If you cannot access the forum any more then it could be that your IP range has been blocked as part of an approach to keep out a recent steady stream of Russian hackers.. Unfortunately other valid users might get blocked also but there is little can be done about that.
One Russian hacker did make it through last week, had a post accessable for about 3 hours and posted just once, part in English and part in Russian. Since then, the server access logs have been reviewed and any IP address range seen to be a viable hacker access point has been blocked. This is being reviewed daily and more new address blocks are excluded each time checked.
If you have been blocked then the only way an unblock will occur is if you directly email me your IP address and user name and I will check the user log.
I will NOT unblock IPs that are from VPNs.
If you don't know how to email me then you need to do a bit of research !

Saturday 6th April at St Michael’s College, The Abbey Place, Caboolture.
Hi,
It’s John Saunders (VK4BZ) from the Redcliffe and Districts Radio Club.
This year’s Redfest is doing things a little differently!
Ladies! We are trying to look after the ladies in our lives as well as the ladies on-air with their own callsigns. As such, Redfest 2024 will feature non-radio related tables focussed purely on female interest areas. There will also be a specialty café with proper coffees, cakes, slices and cookies, along with sit-down café tables under the club marquee. Very civilized! ALARA will also have a presence this year to encourage more ladies to take up this great hobby of ours. So, invite the ladies along this year! (My XYL is coming!)
Technical! For those who want to expand their technical knowledge, there will be a demonstration of the ICOM IC-905, the new commercially made microwave transceiver. The Brisbane VHF Group will also be there to do a Tech Talk on microwave propagation.
Prizes! Raffle prizes are always attractive items at Redfest and this year is even better with the ICOM ID-5100A VHF/UHF FM and digital transceiver as the main prize. There will also be minor prizes as well as hourly lucky door draws.
And as usual! Yes, all your favourite stalls full of pre-loved goodies along with our regular commercial sellers will be there too! Did I mention Dougie’s famous bacon and egg rolls? Yep, the BBQ will be running hot as always.
Food available from 8:00am and the gates are open to the bargains from 9:00am. Major prize draw is at 11:00am. Entry is $5.00 and raffle tickets are also $5.00 (can be purchased prior to the day – see the club website).
See you at Redfest 2024!
John Saunders (VK4BZ)

New amateur radio arrangements have begun
In December 2023, we announced new arrangements for amateur radio, including the upcoming Radiocommunications (Amateur Stations) Class Licence 2023 (the class licence).
The class licence has now commenced. It means qualified amateur operators can operate foundation, standard or advanced amateur stations without needing to apply for an individual licence or pay any fees.
Alongside the class licence, there are new arrangements for qualifications, examination assessors, call signs and overseas visiting amateurs.
Around 180 accredited assessors are ready to conduct and assess amateur radio examinations. We have also opened applications to become an accredited assessor. The Accredited Assessor Guidelines have been updated, providing more detail about the accreditation requirements for applicants from New South Wales.

Audio Clipping on Sideband? |

Is it possible to detect audio clipping on a sideband signal?
I've just recently obtained a bluetooth headset and adaptor. The bluetooth adaptor connects to my Yaesu FTDX3000. I've found that normal mic gains are far too high, so I've had to wind the mic gain back to about 7 to allow for this. Problem is, how do I know when the audio is clipping? Obviously, I want to get full modulation without clipping. I am feeding into a dummy load and monitoring on a RTL-SDR.com device, but it's hard to see if there is clipping or not.
See attachment. There seems to be lot's of harmonics. I've wound back the mic gain and there is less harmonics, but how do I know if I'm modulating 100%?

Flying the flag for the Gippsland uWave stations |

G'day All,
I had a chat today with one of the local Gippsland microwave operators whilst I was driving to East Gippsland. It was noted that whilst during many of the MAD arvo sessions lately, that there are a few portable & home stations in Gippsland that are capable up to 10Gigs and are keen for some of us central Vic stations to work. Hopefully they’ll post their location on the Contest Radar… https://contestradar.com/ particularly for those of us operating up on a hill east of the Port Philip Bay. Some of them have a bit of horsepower on most of the uWave bands. I guess some of us, particularly a few of the newer players, that aren’t aware that there’s some good stations in Gippsland to work.
So to share the wealth, point your antennas towards the Traralgon / MtTassie / Orbost / Bairnsdale direction. And with a little bit of lift in conditions, you may be able to stretch the legs of your gear, work some distant uWave stations and put a smile on your dial. Plus don’t forget to take a few pics and/or some video.
Cheers,
|

AREG - Adelaide Radio Experimeters Group - Hamfest Saturday 25th October 2024 |

G'day All,
I've heard on the grapevine that the AREG might be holding a Hamfest on Saturday the 25th October this year. I've heard that the club may make announcements later on re the confirmation of this event.
Two things...
- Depending on the interest, I was thinking of booking a table or two to demonstrate & promote some microwave gear & operations. Plus I have to return the favour of Iain VK5ZD of his big effort in coming to the Ballarat Hamvention last weekend with his microwave gear to display and help recruit some newbies.
- Would there be a few microwave operators be interested in heading out to work some microwave bands in the days before and/or after? I was thinking of making a week of it - any excuse to make an escape from lockdown central in VK3.
- I'll have all bands from 2m to 10GHz (inc 3.4G) and maybe by late this year I could have 24GHz ready as well.
Cheers,

Antenna Tuner Adjustments? |

G'Day All,
I have an manual Antenna Tuner (Palstar AT2K), which I am trying to make as efficient as I possibly can with my adjustments.
The manual offered very little help other than providing a suggested settings table, which don't come close to what I have.
I am more concerned about 15-10 Meters.
The antenna is a 132' Half Wave End Fed with a 49:1 Unun at the feed point.
The way I am thinking is to have the Caps as close to fully meshed despite where the inductance sits.
I am assuming this will transfer the maximum amount of energy to the actual antenna.
Thought please.......
Pete VK4CCV
