We had 41 reports from our team about our Tuesday net, and 57 stations heard. The reports showed that most of us had fun on the afternoon / evening gettogether - thank you one and all for making this such a great thing for everyone to enjoy. Particularly nice to see so many people trying things, fixing things, building things, operating QRP etc - sure a bit different from what you might hear on the phone part of the bands; old technology is being used to rejuvenate amateur radio and give us all something to look forward to each week. v RSS Happy! Last Tuesday’s Here’s this week’s Group list of the 57 stations heard, thanks to our 41 CQQRS team stations who shared their report with us this week: CQQRS Team Member cQ Heard on air Worked 40m Worked 40m Heard 40m Worked 40m Heard 40m Tried 40m Worked 40m Heard 40m Heard 40m Heard on air Heard on air Worked 40m Heard 40m Heard on air Worked 40m Heard 40m Heard 40m Worked 40m Heard 40m Tried 40m Heard on air Worked 40m Heard 40m Heard on air Worked 40m Heard 40m Worked 40m Heard 40m Heard on air Heard on air Worked 40m Heard 40m Heard on air Worked 40m Worked 40m Heard on air Worked 40m Heard 40m Tried 40m Heard on air Worked 40m Worked 40m Worked 40m Worked 40m Heard 40m Heard 40m Heard 40m Worked 40m Heard 40m Worked 80m Heard 80m Worked 40m Heard 40m Heard 80m Worked 40m Heard 40m Heard 40m Heard on air Heard 40m Heard 40m Heard 80m Worked 40m Heard 40m Worked 40m Heard 40m Qsoi Qs0 2 Qso 3 Qso 4 Qso5 Qso6 QSO7 Qso 8 ZL3TK Heard on air ZL4TE Heard on air Masthead Image The image above Is of my 45 year old Trio TS-50S transceiver and my WT 8 AMP No 2 keys.

The spreadsheets above show the known stations on last Tuesday’s Group. Comments distilled from the reports I’ve received follow: Comments: From Paul VK3KLE at Stawell [40m] e Started the evening a bit after 69m edst with mark vk2ki on my Johnson valiant tx (using its internal tube vfo) with my Drake R4A Rx. Was a long QSO and very enjoyable. e After dinner and a short rest | used my Tentec Omni V for the rest of evening. It's a 1990s rig and | have replaced most trimmer caps and electrolytic caps. They are only reliable for 5000-1000 hrs at best spec. Yesterday | replaced the QMHz IF trap cap. Also some front end upgrades to the jfet j310s. It has very low background noise now without an antenna. Looks good no smoke from latest work on the Tentec - straight from the work bench into a hot QRS QSO.. From Jordan VK3ACU at Meredith [40m] ¢ Had a listen late while mobile on the way home from work. Also a quick contact with VK3DRQ and VK5LJ, apologies if | have noted any call signs incorrectly | was mobile, relying on memory and not concentrating heavily on the CW. Until next week 73.

From Manny GOOD STATION, SIGNALS THIS EVENING QSB QRM TOWARDS VK3DRQ AND AND ALSO LATE VK6, MAINLY EVENING WITH SWL, VK6 at Blackburn [40m] e Even though When | finished past midnight, wasn't happy with what | achieved. | couldn't hear any VKs or ZLs | could copy RUOLL. The joys of Radio! e But, the real BIG JOY was to have used the just finished Noise Canceller from VK5TM. My thanks must go to all of you who insisted in having one, since my Noise level was hardly ever lower than S6. Special thank you to OM Stan and OM Mark. Now | can copy without Noise at all!. e Highly recommended ¢ 73&77 Unit.. Manny. [Fantastic Manny! I’m really glad you have given the VK5TM noise canceller kita go Manny.

From 8 ESE Geoff Hart-Davies tuesdays-group-10332490? e=282909cbd8 / VK6HD at Mandurah [40m] ¢ | was pushing the odds as | was QRP (IC-705 and QMX) with a home brew magnetic loop sitting on my desk inside the home QTH “Faraday cage". Heard a few Stations about 1600-ish and then put out several calls on 7033, but no answer. In an effort not to waste my time, | conducted a highly scientific N=1 experiment by switching between the IC705 and QMX. Witha consistent noise floor/QRM of about S2, due no doubt to the magical qualities of the loop :), | can report that the IC705 just picked up a few local stations, whilst the QMZ did not, which is hardly surprising.. [And a slight relief | imagine mate! Hint.... | know it may not be according to Hoyle, but posting an alert on WhatsApp when calling QRP may pay dividends! Backinmybox!] From Daniel VK6WE at Cottesloe [40m] e Signals were good with several Stations available. However my two contacts used the time | had available before setting off for an evening of fishing! You have to exploit the right conditions and the signals were great at the beach too.. Ernonm Datar Rann VM 2WING! at Riaclhiirn Malhniirna EEiwitlt © WG BVGHEEEE WEIN UW ee UL WIE NVUETT, PICU [40m] e Felt awful after | managed lose to both my initial contacts of the evening VK2NNW) In noise (Adam and in an extremely sudden fadeout from 579 119 with David VK3DBD. to Very different operating in real radio conditions from working on VBAND or using the Morserino server. e Apart from my usual sending stumbles, my embarrassing moment de resistance was surely working VK2KI and completely failing to recognise that | was actually talking to Mark Bosma. Doh!. [Well! For a start Peter, your CW sounded very good to me - no stumbles heard from your end! A year ago you reported having your third CW contact in 40 years on the CQQRS net... sure didn’t sound like you've forgotten much of your keying experience. And secondly - nearly every week | chat to people who have better things to do than try to remember peoples’ names. Rest assured that | can’t remember people’s names 1.5ms after they’ve told me face-to-face. only just. On air Is slightly better... but | use an electronic list on my phone of the names of the 200+ members of our wonderful QRS team!] From lan VK7TA at Latrobe [40m] e Conditions were pretty good. Not so much heard around 1830 local time, but things improved when From Keiran | returned after dinner.. (Bad Tempered Victorian) VK3BTV at Lilydale, Victoria [40m] e Thanks Manny VK3DRQ, VK5AO Mait and Greg VK5KFG for putting up with my clumsy lOwpm - | really need to practice more [i.e. practice full stop :) ] [Sounded pretty good to me when | eavesdropped on your QSO with 5AO mate! From Solid signal up here too. / Peter VKO6IS at wundowie [40m] ¢ the band was an little more active this week,. e then it got quite noisy later on. e with few ES stations heard..

From Greg VK5KFG at Willunga [40m] ¢ JAOBZH was readability 5 and calling "CQ QRS PSE". | was happy to oblige but did not quite make the return journey.. From Phil VK6GX at Gidgegannup [40m] e Plenty of activity from both sides of the country and in between. Good propagation, but no ZL's heard, even on the two Beverages.. From your editor Mark VK2KI at Beautiful South Bowning NSW [40m] e At the start of the net | heard Paul VK3KLE at Stawell testing his now-so- Stable Johnson Valiant transmitter, in combination with his Drake R4 receiver. lan VK/TA at Latrobe and | both tried calling Paul without luck. lan went on to chat to Brian VK2EBW at Newcastle, and | finally hooked up with Paul for a long relaxed chat about his modifications to his classic transmitter; now his transmitter was more stable than my drifty old Trio TS-120S.. e Next | was called by Pete ZL4TE near Hamilton; it was great to have a chat to a Kiwi on the net again; things have been pretty quiet across the Tasman on Tuesday evenings; conditions were marginal, but we had a nice chat. Having had so much fun in Samoa last year, Pete was eyeing off Niue Island.. e After dinner | hooked up with Maity VK5AO using his sloping dipole up 13m at Banksia Park, then Peter VK3WOW at Blackburn - both nice long rag chews. Peter had a nice signal into Southern NSW, and confirmed that he was now using an inverted-L antenna, versus the doublet in the ceiling that he used when he first joined the net. That QSO was followed by our nearly weekly tradition of chatting to David VK6KD portable - this time at Coobowie on the Eastern side of the Yorke Peninsula.. e After David, | was called by Max VK6FN at Manjimup; although Max and | chat regularly on the WA AllStar network (which comes out on a $20 70cm hand-held in my shack via my Raspberry Pi AllStar node), it had been over six months since we'd enjoyed a CW QSO. To finish the evening | had a chat to my complement, Paul VK2IK 140km ENE at Moss Vale. Paul had recently reestablished his 40m antenna after losing it in one of the many recent storms.. ¢ A terrific night - lots of stations and really nice rag chews; thank you one and all.. [80m] e After chatting to Paul, | had a quick look down on 80m. The VK1CM KiwiSDR Showed that the band was quiet - and after a number of CQs, | confirmed that - eventually padding off to bed at around 12:30am to prepare mentally for the Post Morsum callback at 9am.. From also from your editor Mark VK6QI Brookton [40m] e Nice to hear a bit of activity via at via the VK6QS KiwiSDR near LIIC VNUYO NIWIOUYIEIN LICdal DIFUURLUTI before dinner here. The band started to open to the East at around 0815z with some weak signals appearing on the waterfall soectrum display.. e Then after dinner at around 1000z, | watched my QSOs from VK2 with Maity VK5AO, Peter VK3WOW, David VK6KD/5, Max VK6OFN and Paul VK2IK all coming through nicely into WA.. [80m] ¢ 80M was quiet when | finally slid down for a look. The band was open nicely across Australia though, with strong signals from my 50 Watts from NSW.. From Richard VK6PZT at Dalyellup As you have probably guessed I’m flat out with my new imaging clinic in Busselton at the mo, so | can only get on air about once every three weeks or so. From Nick VK6DV at St James WA [40m] e VK6KHz Ron - thanks for the QSO. QSB and local noise made it almost impossible sorry - glad we made It though.

Certainly made me pay attention!. [Heh heh - the witches’ conversation will remain a mystery by the sound of things. The Vs you heard was probably me testing the NSW to WA path, as is my want!] Post Morsum Callback - Wednesday From Richard VK6HRC Well we managed to keep the AllStar/ Echolink and linked SW repeaters busy for nearly one hour discussing CW, small farm activities and lots of other topics on Wednesday morning’s post morsum callback. On this morning : VK6HD-~ Geoff VK6QI Mark VK6OFN Max VK6KD/5 David VK6HRC VK6MRB swl and others. Geoff called in during his morning walk to let us know that he tried a magnetic loop from inside the Faraday cage he calls home. He was doing a signal comparison Was hearing between his IC-705 and QRP Labs QMX. Signals on the 705, but they were not strong enough to work. Mark was busy feeding chickens and picking grapefruit in Edible Avenue and reported that from the East he logged seven long ragchews on forty and heard another seven stations; VK6QS he also heard 13 stations via the KiwiSDR in the West. Max got the mighty Flex radio going nicely at last after sorting out last week’s embarrassing side-tone problem, and logged six contacts on forty with a good mix of QRS and QRQ. David logged four contacts on forty but the gremlins returned on eighty so nothing logged there. | had one contact on forty one on eighty and spent a lot of time monitoring the traffic over East on the KiwiSDR - a great mix to work on decoding skills.

You can just pound the square brackets keys or the CTRL key on your keyboard (or prod at a touch screen If you really must), but VBand Is much better when you use a proper Morse key. The VBand website owners sell a device that will allow you to connect your key to your computer, Shipping + custom but they're based charges can make in the USA and therefore it rather expensive. My OQRZ.com page gives details of how to convert an old computer mouse for this purpose - | think Richard VK6HRC has had a go at that.

[Thanks Jordan and Nic. LM741 At less than $2, operational amplifiers like the are a snazzy way to create some really interesting analogue circuitry. The opamps work on a differential inout - one input produces an in-ohase output, the other produces an out-of phase output and the opamp amplifies the difference in voltage between the two inputs. The opamp has a very high gain which is controlled via negative feedback via external components from the output back to the inverting input. In the filter, the output Is fed back to the inverting input via the high pass filter (the three O.O1UF capacitors and the four resistors connected between pin 6 (output) and pin 2 (inverting input). The higher frequencies are passed from output to inout better than the lower frequencies, which means the higher frequencies produce more negative feedback - ie produce more gain reduction than the lower frequencies. The difference in opamp gain between the low and high frequency feedback effectively amplifies the filtering effect of the feedback circuit - in other words, the simple broad high pass feedback makes the opamp produce a much sharper and deeper low pass filtering effect. Inverted from Really clever - thanks for sharing Jordan and Nic.] L Antenna Peter VK3 WOW Here are some antenna. photos showing how I’ve set up the end-fed inverted L | found the key to making this setup viable was using the right sort of wire. | was originally trying to use JayCar hookup wire, and it was WAY too heavy. As soon as | switched to using the much lighter stainless steel wire, the whole thing became practicable. much more The Inverted-L now effectively functions as a stealth antenna — easily raised and lowered. With best wishes, Peter VK3WOW Common Pee eee PA Mode IS ONT Choke to Reduce Noise. -FrOM) RICK VAOAI Something we rarely think about is the outer braid of our coax fed antenna. It is a conductor stretching from the chassis of our rig to within Inches of the antenna. A common scenario Is noise from the shack power Supply and computer etc Is induced onto the braid as a so called common mode current. Guess what happens when it reaches the end nearest the BALUN... picked up by the very sensitive receiver! The reciprocal situation also happens where RF being radiated from the antenna Is picked up by the braid and comes back into the shack possibly causing RF feedback on your microphone or squiggly lines on your monitor. This should not nappen if you have a perfect BALUN drops away at right angles from said antenna. and the feed-line Rarely do we Nave sucn a perfect set up. Anyway cutting to the chase, one way to stop the nasty things happening Is to Insert an RF Choke onto the braid of the coax to disrupt this current. RASS | needed to do this and found an easy way that really works. Been The big electronic stores have ee : . Split core ferrite chokes available.

[Thanks Rick - an easy thing to try for those of us troubled by switch mode power supply hash, or stray RF where it shouldn't be. These things can also be used as a Quick and easy alternative to a BALUN at the feed-point of your antenna - either wound as Rick described, or with multipole clip-on ferrites in series. minikits.com.au Is a great source of RF components for amateurs and has lots of good information in the Downloads section about ferrites. / Johnson Valiant Transmitter From Paul VK3KLE Here is a CCT for Collins kw-1 . Find the 6ab6 vfo is similar to a 6au6 in Johnson valiant. A receiver tube . Both screens and plates are VR tube regulated for the vfo tube and buffer tube. The Johnson has a massive 6cl6 tube that's high current -something be required . like 40ma reg would 4TH MULTIPLIER The Collins KW1 is a nice circuit, but before anyone gets too excited about getting one and putting it back on air | should provide some advice, care of my Elma Brian now sk from America.. Frequency multiplication on CW is now discouraged within USA CW circles due to unwanted harmonic products and our very crowded bands. He advised the best idea these days with ancient transmitters is to run the chain straight through without multiplication, using a doubler at most; 80m VFO or crystal for 40m. ie Sounds fair enough to me. The Johnson Valiant keys an 80m rock best on 80m and 40m and as per the manual, 40m crystals can be used for higher bands. It uses a Seriestuned crystal oscillator dual purpose buffer with semi-tuned low Q plate output tank. Recently, following advice from a local Elma | checked the buffer class. From the home builder or factory it had a 470 ohm resistor on the 6cl6 cathode. Other drawings show no resistor here. So I've put a low value hd 47 ohm resistor to the cathode to make the tube when class A. There are other CCT varieties on various revisions including a 33k used as a buffer in or 100k grid leak resistor. My set keys better with 100k. So for those interested in old or new tube transmitters I'm quickly learning every single element and component is of critical importance in these simple ccts. | believe Brian said some builders have run new modifications with voltage regulation on everything up to the pa tube plate, including screen regulation. Now that's a lot of additional circuitry. dropping resistors either; Ideally no big value seperate transformer taps to get every voltage in the ball park for its seperate voltage regulation. I've yet to see a home brew tx built like that, but I'm sure they are about. My improvement uses two 10w zener diodes providing a regulated VFO plate supply on the 6au6 tube, which only needed two small chassis holes that I can live with. A second 6au6 or babe buffer would be very tight, would need a big hole and could be messy and tricky to do. The two lLOw zener diodes are In series, giving 240dc to the plate of the VFO tube. | reversed a previous mod on the buffer tube by reinstalling a LOOK grid resistor in place of existing 33k ohm - it was loading the VFO causing some additional chirp. A couple of times in our QSO on Tuesday | nudged up the vfo, but overall using the ten tec omni as a monitor we didn't vary that much. Please keep in mind that this very old transmitter has the be 1950 500pf mica caps and It's Original temperature compensating dog and bone ceramic Caps. So the temp Stability we all are hearing is Stock minus the new 240v DC regulation of only one vfo 6au6 tube. It's has its own stock VR tube on the screen. That's a fair effort for 1950 technology and longevity. In Tuesday’s station setup | used a MFH noise preamp with relay ant switching and a vintage netcurtus CW keying sequencer. Not much clicking and semi qsk just from the key Also short video using my ten tec as a receiver of the dummy load Signal from the Valiant. I'm showing off keying with my left hand for a laugh. Best Regards, Paul VK3KLE QRZ? Who’s This week on the other end? - Peter VK3WOW In my work life, | made an intermittent living for a while writing TV police shows and soap operas (Bellbird, A Country Practice), plus some documentaries for Film Australia and some TV comedy writing for Max Gillies. While all that was ‘fun’ (sort of) it didn’t really help pay off a mortgage, so | worked as a labourer, TV station operator, psychiatric nurse, taxi driver and taught history and English, before working for many years as a technical writer, working exclusively on software projects. Since retiring, I’ve turned my efforts to writing prose fiction, and particularly novels. As it happens, the central character of my partly autobiographical novel 1961 (https://www.peterdannauthor.co m/1961 novel/) gets interested in radio/electronics as a twelve year old, inspired by his reading of “Radio, Television & Hobbies” (a magazine of that era) and by his contact with a radio/TV serviceman who lives next door, and takes him under his wing. So, not a million miles away from my interests as a radio ham, you might say. I’m writing another novel now. | find it slow and challenaina (hit DN re ee ge very interesting) work. I’m not, in any sense, trying to write genre fiction (detective novels, SF novels, etc), so that adds a level of difficulty — but at the same time, that’s where my interest lies. With best wishes, Peter Dann VK3WOW QRZ? I’m really keen to share backgrounds of some of our team members - it’s really good to know who’s on the other end of the QSO.

I've checked on PARG's website but there's no indication that the event has been cancelled. As a radio operator, one gets used to the vagaries of propagation and failed skeds. | shall try again Shortly. If I'm not coming out in Western Australia, my best wishes go out to PARG and | hope that your get-together and raffle are a SUCCESS. For myself, | shall shortly be 140 visitors demonstrating that PARGFEST 2025 was a great success heading back to bed. Night night all. [Wouldn't you Know it! In previous years, PARG set up the emergency coms trailer PARG1 outside the venue and rewarded by a constant supply of sausage rolls, one of the members manned the trailer and ran a talkin. | don’t know if that happened this year. As it turned out, | was away on Friday and Saturday (and | hate to admit, actually forgot about PARGFEST) so! wasn’t listening in this year. If |! had been home, you can bet your bippy that | would have answered Ross if | heard him. Later that morning | was called by Rob VK6LD who had built most of the AllStar nodes on the WA network. Rob said that he happened to be visiting Mandurah but that the node didn’t appear to be connected to the network. / had built the AllStar node as the repeater controller for PARG, so | was able access the node’s Supermon make the connection. website, see what was going on and re- It turns out that at some stage in the morning, someone had accidentally or on purpose sent a bunch of random DTMF codes to the repeater, network. which managed to make it disconnect from the So Ross was connected to the repeater (and would have been heard in the area), but the usual Al/Star network wasn’t connected. Thanks for trying Ross - would have been nice to say g’day.] Wanted - An QRZ.com article page on /@aar> creation fause au I’m keen to help all of our team members to create a nice qrz.com Wien page, especially if it espouses the joys of slow CW! page? Do you have a qrz.com If so, would you be interested in sharing how you created the page with others on the team? If you're able to help, please let me know first (in case there’s a flood of offers!), and then put together a few paragraphs (yeah, yeah, | Know!) on how to do it... step-by-step, with some from go-to-whoa pictures of the steps used to go if possible (or I’m happy to help with the pictures if you don’t have a screenshot-type application to grab on-screen Please let me know if you’re interested: pixels). cqgrsnet@gmail.com Di-dah-di-dah-dit Here So back to the Slow CW QSO Next Tuesday’s Our CQQRS we go. practice net. Net Group will be on as always on Tuesday from around 0700z until about 1300z; see below for details. Doesn't matter whether you’re brand new and want to try just exchanging callsigns and RST reports, or you’re ready for a good old rag chew. We'll have fun. There's usually people around until after 1300z - so keep calling in the segment of the band designated someone. in the table below until you catch | should be on as usual from home in NSW or via the Remote at Bedfordale WA, and I'll also be watching the proceedings using the VK6QS and Tecsun SDRs in WA and NSW respectively. Hope to hear you there. Reports Please let me know via our Reports form bit.ly/CQQRSNET who you work or hear on Tuesday’s Group. The report form closes at lunchtime (Eastern Australian time) on Thursday. Post Morsum Richard VK6HRC will run our phone Post Morsum on the South West AllStar net (via repeaters and hotspots all over WA) from 0600 WA time, then from 0700 WA time on 80m (3605 LSB). For the 0600 (22002) net, if you’re in WA all you need is an FM 2m or 70cm transceiver and an AllStar node nearby. If you’re elsewhere in the world, if you have an AllStar node (or you may be able to connect your local AllStarenabled repeater to the net via DTIMF codes), connect to node 42482, 51077 or 42732 - these are the hubs that tie the network of repeaters and nodes together in WA. If you don’t have access to AllStar, you can connect to the network via Echolink. On Echolink, search for one of the following Nodes: e VK2KI-L e *VK6-HUB* e VK6ZGN-L e VK6RMH-R e VK6NRA-L When you connect to one of those stations on Echolink, you'll be automatically connected to the WA AllStar network, and you should hear us on soon after the hour; let me know (cggrsnet@gmail.com) with connecting via AllStar or Echolink. if| can help If you’re in WA and can’t connect, give Richard a call on 3605kHz SSB from 0700 (23002).

QRL? So tune around and call anyone you hear, or find yourself a quiet spot in the designated segment, send “QRL?” and if the frequency is quiet, start calling CQ QRS at about 75% of the speed you're comfortable receiving at; hopefully responders will match (or send slower to their comfort level). And if you are already having a QSO and someone sends “QRL?”, respond with “R”, “C”, “Y”, “YES” or QRL to let the caller know that the frequency is in use. If we’re on 40m and you can hear that the band is open outside Australasia, perhaps consider calling 500HzZ above each 1kHz slot - to minimise the chance of having to copy our team through QRQ QRM that’s often dead-on the kHz markers. Speed? Rhythm? If you’re proficient at CW and can race along at 20 or 30wpm - terrific, but please remember, the Group’s aim is to encourage participation and learning, not show how fast you can hammer the key. Please send slowly where you can and concentrate on rhythm - listen to your side-tone, get that wrist action going and make a special effort to make perfect CW; how many it sound like the longer we go with our Group, the more | understand just non-transmitting listeners we have - and they will most likely appreciate your QRS! So, if you’re an experienced operator, please try to send nicely balanced slow CW to give them a chance to practice and gain confidence.... they’ reward you one day by coming good up on air to say g’day and thanks - how is that? And if you’re new or like me, just rusty.... ignore the above... just have a go - the lather of sweat will be worth it and there’s plenty of time to get the details sorted out as you practice. Matching And also for the oldies like me, when you hear someone their sending speed - or slower. new, please match The person you’re replying to may not be as deft on the decoding as you - it may be their first ever CW QSO remember your first? Lather of sweat, key that refuses to send that you tell it, brain that refuses to decode those complex letters that were right there half an hour ago, etc! PSE QRS And if someone is sending too fast to comfortably copy - “PSE RPT PSE QRS” PSE or “AGN? QRS” will make life easier for everyone.... and might just encourage other listeners to have a go themselves. The other thing to remember - most operators are writing down what they hear... so when you put it back to them, expect a delay while they read your words of wisdom, Whose frequency before replying. is this anyway? The aim is to give everyone a go at contacting others - no-one owns their calling frequency in this Group. So unlike working someone DX, if you hear signing off - jump in and call - doesn’t matter who was first on the frequency - we really are all good mates in this Group.... and besides, at the speed we’re sending, after a QSO most of us will have forgotten who was first! If you really want to move off frequency (eg because of a spurious switch mode power supply signal that’s just drifted into the conversation), you could try sending an abridged callsign of the person you’re after, followed by “UP 5” or “DN 5” then K; then call that person on the designated frequency and keep your fingers crossed, they may have understood you and followed... or not. landina 7Fona RCO Ey ee If the band goes really quiet, call and listen on 7032KkHz (7028kHz secondary) or 3555kHz. If you catch someone, there’s no need to QSY enjoy the frequency. But don’t forget to tune around if it’s quiet - we have lots of operators with crystal locked transmitters - and they could be anywhere within the segments. For those who are locked, or can only transmit outside the segments, send a message on our WhatsApp CQ QRS - Alerts group advising of your current frequency. And of course, put the frequencies in a memory so outside of the Group, if you’re not tuning around, leave your receiver on one of the primary frequencies - you never know who you'll hear (7032 is used in VK and ZL for SOTA/ PARKS during the day so you'll often hear activity there).
