VHF Field Day Feb 12, 13th 2022
Let us hope for better conditions….PLEASE
- HWB – Off air – WIP Back on air soon.
- EE122 – The Analogue/Digital repeater is restored. If it is in the digital mode, you will hear noise on an analogue receiver so it is advisable to have the 141.3 CTCSS enabled on your EE122 analogue channel.
- UHF DMR – now all connected to the network so no longer operating as just a local repeater. You can now talk to the world.
Topics for 2022 meetings
- Educational: Electronics and RF matters incl Arduino programming, applying design software eg Eagle, KICAD, LT Spice, and EZNEC (now free!)
- PCB Design and construction capability, by 3D printing? & new soldering stations
- Computers IP and IT topics & sessions configuring wireless IP Links and Access Points
- AREC training to widen our capabilities for SAR and related events
- Continuing the development of resilient systems locally and across Otago
- Preparations for the National HF Jock White FD
- Preparations for a 100th anniversary of the famous first trans globe radio contact
- The 100th anniversary of Radio Dunedin in public broadcasting
- Plus many topics from our members eg, Welding and welders, Home solar Wanaka, HF Radio, Using FT8, Projects completed or under way, our KRD Site and APRS.
- Design a simple VHF Yagi to allow Home Stations to listen for Wander Track signals
If you would like to help with a presentation, please let TT know. Allan ZL4MD has developed our Zoom capability to allow us to take presentations across the country.
After the report last year that Solar Cycle 25 might be a fizzer, Ol Sol has been sparking away to its own tune. Dec 2021 sunspots were double the predictions and some big CME’s have occurred. One happened one afternoon in Late Dec and caused about an hour of surging white noise across 6m band. Keep listening out there, you might miss something.
Six Metre Band
A wonderful opening to Japan and China just before Xmas saw full screens of FT8 traffic for about an hour. (I worked one station with my humble 10 watts). But the Magic Band has been pretty flat since with few contacts and weak beacon sigs.
New Amateur Satellites
From ARRL: EASAT-2 and Hades Satellites with FM Repeaters Launched
The EASAT-2 and Hades satellites were launched on January13. They both have not yet deployed antennae so sigs are weak. For latest info: https://www.amsat-ea.org/ .
Please share reception reports with AMSAT-EA: http://data.amsat-ea.org/ .
EASAT-2 was designed and built by AMSAT-EA and students from the European University of Degrees in Aerospace Engineering in Aircraft and in Telecommunication Systems Engineering.
* EASAT-2 Frequencies: 145.875 MHz uplink, FM voice (no subtone) and FSK 50 bps, AFSK, AX.25, APRS 1,200/2,400 bps. 436.666 MHz downlink, FM voice, CW, FSK 50 bps, FM voice beacon, callsign AM5SAT.
* HADES Frequencies: 145.925 MHz uplink, FM voice (no subtone) and FSK 50 bps, AFSK, AX.25, APRS 1,200/2,400 bps. 436.888 MHz downlink, FM voice, CW FSK 50 bps, SSTV Robot 36, FM voice beacon call sign AM6SAT
But there’s more:
The eight-Satellite TEVEL Mission launched on January 13 on the same SpaceX truck.
The TEVEL mission consists of eight satellites carrying amateur radio FM transponders and were developed by the Herzliya Science Center in Israel.
All eight satellites use the same frequencies, as long as their footprints overlap, and only one FM transponder will be activated at a time. Beacon transmissions will be on 436.400 MHz (9,600 bps BPSK). The uplink frequency of the FM transponders is 145.970 MHz, and the downlink frequency is 436.400 MHz. The satellites were built by eight schools in different parts of Israel. https://amsat-uk.org/2022/01/12/tevel-satellites
