Midlands Microwave Round Table

Post by G8GKQ » Wed Nov 29, 2023 4:24 pm

The BATC will have a stand at the Midlands Microwave Round Table this Saturday.

In addition to the normal shop stock at reduced prices, we will have uncalibrated noise and power measurement facilities for all the microwave bands up to and including 24 GHz (150W limit on 10 Ghz and below, 100 mW on 24 GHz).

And of course Digital ATV transmit and receive testing, fault diagnosis and fixing. Also a Raspberry Pi 5 capability demonstration.

Dave, G8GKQ

Excellent, I'd like to compare my measurements of NF on my 3.4GHz Ionica-based receiver, plus lots of dishes/antennas to evaluate in the chicken shed.

I also have a HP Server PSU '50Volts' (can be tweaked up/down a bit) at 35A + if anyone would like it - I paid £20. Surplus to requirements, and storage space at home.

Hello all
Im looking forward to this weekend's round table. Are you coming too?
Im bringing this year's model of Portsdown 4 transceiver to demo. I filled the 19 inch case John!
I've the 10GHz transverter looking for an expert to take home to commission.
I've a Ryde receiver which doesn't receive that needs examination. The Minitiouner works as an Rx in its own right and the software on the pi is up to date with working remote control. I'm proper puzzled by it. If the repair desk has a spare pi 4 it might be useful in diagnosis.

Regards

I'm looking forward to seeing everyone again. I hope to bring my noise source for calibration, please.
