- FAMPARC Club Repeater VK3RMC (NET)
Hi Members, We have been very lucky to have had a lifelong member run our Tuesday night nets. Bill VK3MMM has been in the hot seat for many years. I cannot remember a time when he has not been at his radio at 8.00pm on 146.425. Whilst local members have no issue with joining the net. Other members who live further away report they cannot hear the net. A recent discussion at the club regarding the use of a local two metre repeater resulted in. Mr Ken Millis who is the secretary of the Moorabbin & District Radio Club offered their two meter repeater VK3RMC to Famparc to run our Tuesday night net. We are most grateful to their club for this very kind offer. Bill's radio has been set up, and found to fully quiet the repeater. Next Tuesday 12th July at 8.00 pm Bill will open the net through the repeater. Members will require to tune their radio as follows 147.325 up 147.925 and include a tone of 91.5 Please be aware the Moorabbin radio club holds their net meetings on a Wednesday. Please avoid disturbing their meetings, or you are most welcome to join in for a chat. As one Famparc member suggested, perhaps we could all monitor this repeater at other times. Repeater Details: Aprox. Location: Narre Warren Vic. Output Freq. 147.325 Input Freq. 147.925 Repeater Tone: 91.5 Grid Location: QF21PX Please do your best to join our clubs net each Tuesday at 8pm via the repeater.. At least make the effort to check in and check out if you are pushed for time. Enjoy what your club has to offer.. FAMPARC Don't forget our For Sale section on our Forum !
- BAREC Field Operations Group.
UPDATE REMINDER When: Friday August 19th at 7.30 pm. Where: Bendigo East Hall, 35 Lansell St. Contact: Graeme, 5441 5461. Official Launch of the BAREC Field Operations Group - Friday August 19th at 7.30 pm. Bendigo Amateur Radio & Electronics Club invites you to our August meeting - theOfficial Launch of the BAREC Field Operations Group, presented by Neil VK3ZVX. This Special Interest Group will focus on BAREC's contribution to Community Support during a regional emergency. Its mission is to Plan, Prepare, and Train for the inevitable. As an Amateur Radio Club, this is the most important work we can do. The first step in this process will be a Show-and-Tell night with a focus on Field Operations (SOTA, Mills-On-The-Air, Parks Activations etc). So if you have:- a Go-Kit, - a good box for a Go-Kit - a Squid Pole antenna of any sort, - a favourite Wire Antenna, - a portable Antenna Mount, - a Shack-in-a-Box, - a Shack-in-a-Sack, - QRP rigs, - Batteries, - Battery boxes, - Portable/camping Solar Panels, - a Pedal Radio setup, - Portable Logging Hardware / Software, - a Compact ATU, - something that you think is worth demonstrating - e.g. WinLink, Digital Mode - or anything else which might help you to operate away from home and without mains power, - even if it is only a half-baked idea, a half-built project, or a pile-of-bits for one ...BRING IT ALONG... (...and be prepared to explain it if need be...) What matters is that we get the widest possible range of ideas and inspirations. This will enable us to design BAREC's Go-Kits with the cleverest solutions from our combined experience and skills. Our Hall is well heated now, but with covid numbers rising again we encourage everyone to make their own best decision about attending. Masks, hand hygiene, and social distancing will apply for everyone's well-being. The presentation commences at 7.30 pm, Friday August 19th at BAREC Headquarters, Bendigo East Hall, 35 Lansell St. A gold coin donation would be appreciated, and a light supper will be provided. For more information, contact Graeme on 5441 5461. The presentation will also be made available after the event on the BAREC YouTube channel at: https://www.youtube.com/channel/UCyg-RkGPc5yn5Mgp0gVJIrA
- Harlow & District Amateur Radio Society
Photo Friday: Harlow & District Amateur Radio Society (HADARS) recently ran a Radio Masterclass for Year 7 pupils at Robert Barclay Academy, Hoddesdon. The young people experienced morse, satellite, voice and data communication, as well as successfully building their own one chip, digital FM radio. Altogether over fifty confirmed QSOs were made using VHF, HF and data modes. Each pupil was presented with a certificate of achievement for completing all the activities, as well a printed QSL card for the special event call used on the day (GB0RBA).
- The microphone gain game ...
Foundations of Amateur Radio The microphone gain game ... One of the most misunderstood settings on your radio is the microphone gain. You'll often hear people talking about adjusting it up or down depending on what they hear and the results are often displeasing to the ear. The very first thing to know is that the microphone gain is likely the single most audible setting on your radio, right after the tuning frequency. It's pretty much the first variable between your voice and your transmitter. Set it too low and you'll hear nothing, set it too high and you'll hear gibberish. I said it's pretty much the first thing, but it's not the very first. That's your voice, unique in all its glory, loud, soft, happy, sad, funny or not, it's the thing that your microphone captures to transmit. Closely coupled to your voice is the distance between your mouth and your mike. The closer you are, the louder, the further, the softer and the more background noise creeps in. As an aside, speaking of noise, there's background noise at play, but there's also the noise that comes from the audio circuitry itself, which can for example change depending on the temperature of your radio. I'm going to refer to both as noise here, even though they're slightly different. So, starting with the ideal model where you always speak in the same way, at the same volume, at the same distance from the microphone, with a constant temperature in your radio, at all times, the next thing is the microphone gain, or gain. Gain is an imperfect attempt at corralling your utterings into electrical signals without causing the audio circuit to distort or drown in noise. Distortion comes as a result of overloading of the audio circuit when the gain is too high, causing clipping, which essentially changes the audio waveform into something that no longer resembles your voice. At the low end of the gain range there is no difference between audio and noise which results in your voice being buried inside a hissing noise. You might wonder why we don't just build transmitters that cannot clip and increase your volume. Well, we do. We use things like AGC, or Automatic Gain Control to attempt to prevent such things from happening, but this isn't perfect. All this results in the microphone gain being a setting that you need to tune to your voice and adjust as things change. Overall, the best outcome is when you set the gain so the AGC just engages when you talk normally. This gain setting also applies to computer generated signals, often fed into your radio via an audio or microphone input. If you set the gain too low, noise is the problem, set it too high and the Automatic Gain Control will distort the signal to the point where it no longer works and causes interference for everyone else including the station that you're trying to contact. On older radios the output power was fixed. This is also true for Software Defined Radios. To reduce output power, you can change the microphone gain down and reduce the power. Change it to halfway and your output power is essentially reduced to half power. This works for a range of settings, but get too low and we're back to noise and audio fighting each other. The opposite isn't true. You cannot increase the microphone gain to increase power. The moment you exceed the audio circuit range your signal is distorted. On an SDR this means that you're exceeding the ability of the Analogue to Digital converter to represent your audio. In digital terms, zero means no sound and all on means 100%. If your audio is so loud as to only be 100% on, that's like sending a tone out the transmitter, resembling anything but your voice. All of what I've talked about is related to SSB signals and to some extent AM. FM is a different animal entirely. For starters, output power on FM is fixed. The next difference is the signal or channel width. Without going into full detail, FM comes in different widths, WFM or Wideband FM, NFM, or Narrowband FM, and between the two, "normal" FM. To make things more fun, not everyone agrees on what each one means at any given time. Also, channel width and channel spacing are not the same thing, but that's for another day. Gain aside for a moment, consider two matched FM radios using the same channel width. Your voice volume is determined by how much of the channel you use. Louder means wider, softer means narrower. Adjust the gain up, the signal gets wider, but the limit of the channel width remains, get too high and it clips at the channel width and distorts. At the other end, changing the gain down, you'll use less of the channel width and eventually the noise and your voice will be at the same level and you won't be heard. Let's look at what happens when you use a normal FM signal to transmit to a narrowband FM receiver. Essentially your signal is too wide and the result is that your voice will be clipped unless you speak really softly or if you've set the gain really low, either way comes with more noise. Similarly, if you transmit a narrowband FM signal to a normal FM receiver, then your voice will be very low, regardless of the microphone gain setting and turning it up will only distort it due to clipping inside your transmitter. So, for FM, before fiddling with the gain, make sure that you're using the same FM mode as the other station. One thing to remember is when you use a repeater, if the audio is always too loud for everyone, your mode is probably too narrow. Similarly, if the audio is always too soft and you always need to turn up the volume on your radio, your mode is likely too wide. Check your radio specifications to determine what each mode means. In broadcast audio this whole thing is managed by calibration using standard tones, but as amateurs we tend to rely on other people reporting their feelings on the quality of your voice with the often heard admonishment to adjust the microphone gain.

- 40m VDSL filter for your NBN
A few of us have been battling with our HF transmission knocking out our NBN connection. This creates all sorts of problems especially to our loved ones who are trying to use the home Internet. I stumbled across this page on Andrew's VK3FS Blog page. Here! Comments from his site: 40m and Australia's NBN delivered over FTTN just doesn't mix. It's like oil and water. Transmit on 40 metres and kill the internet.... For further information Click here to visit's Andrew's VK3FS Blog Page. UPDATE! 4TH AUG. Update as of 4Th Aug. I received this tiny RF Choke from my good friend Richard, VK3TXD on Monday and installed it just as the image shows above.. I have been testing it over the past few days and since installing this tiny piece of magic, so far.. it works!!!! Amazing.. Thank you to both Andrew VK3FS and Richard VK3TXD.

- IC705 - TAKE CARE
Recently one of our members had a small problem with his IC-705.. Nothing major, but it was a situation that it best not to use the rig. The problem is that tricky little Micro SD Card Slot.. It can be very fiddly to eject and insert the SD Card. Mainly because of the position of the SD Card Slot and size of the SD Card, being a Micro Card. The problem he encountered was when he tried to insert the SD Card back into the slot, what can happen is that you may insert the card beside that actual carrier of the SD card (The Slot), and when this happens the card can be pushed further inside the case, thus causing a nightmare. The SD Card can then not be retrieved. Once this has happened, it is best to contact Icom as did the owner, and it was quickly fixed. Or if you are game, dismantle the radio to remove the misplaced SD Card. (Not Recommended!) The good news is that the repair was done at Icom and no damage was done to the transceiver.. Good news hey !! So.. be careful when inserting that fiddly little Micro SD Card, as it's very easy to insert incorrectly. Craig. vk3ncr
