14th Feb Woodford Park meeting is a chance for us to catch up on the
various projects/activities we’re up to – in particular any follow ups
to the Great Construction Contest but not limited to that.

If you’d like a short (5 minute or so) slot let me know.

Doesn’t have to be stuff – could be contest updates or how RADARC
contributes comms to events like 3 towers etc.

Also – what would you like to see and I’ll try and arrange?

We can take contributions on the fly on the evening if need be.

• Min G0JMS will kindly bring along a RigExpert HF to VHF SWR meter (Digital display) RigExpert to show you and VHF to UHF swr power meter (Cheap unit) which includes frequency. He will also do a brief demo of Yaesu Fusion – Wires X technology RF paths permitting.

If necessary, I’ll bore you for a few minutes before the bottles and
tomatoes start flying:

• Geostationary satellite project – es hail 2. Mike G4CDF (and possibly others???) is making the running on this one but I will present on his behalf a very short overview. iirc it’s 2.4GHz up and 10GHz down. tx/rx is based on an SDR transceiver (lime sdr mini).
• Adventures with FT8 internals and taxi radios (generating FT8 tones by pulling a carrier around) – update. TBH anything that generates a stable carrier and can be pulled a bit maybe down to 1Hz resolution looks like it might work – eg. voltage controlled oscillator.
• cheap RTL-SDR dongles (£15 delivered). Mine does work but probably better to get the real ones rather than fakes like mine.
• short gnuradio demo (maybe)

We’ll have the ICOM IC7300 out for people to have a play with and the spectrum analyser.

Tea, coffee and biscuits will be in plentiful supply all evening.

Looking forward to hearing from you.
