Red Pitaya monitoring station
Posted: Mon 21 Jun 21 2021 2:27 pm
With 9V1RM relocating away from Singapore - we will need to have a monitoring station for the purpose of tracking band conditions and detecting openings. For years, Rath has been providing that service quietly for all of us but it is time for the baton to be passed along.
The Red Pitaya that 9V1RM is a good platform that allows for simultaneous monitoring, decoding of FT-8, CW, WSPR, RTTY skimming all at the same time across multiple bands. The hardware is a Red Pitaya Stem 125-14 (SGD502.96):-

Casing (SGD87.02):-

For the loop pre-amp, a Cross Country pre-amp (USD70 = SGD94.18):-

A bias tee is needed to power the pre-amp (SGD5.34):-

Pavel's software is ideal and we have to work out a way to get skimming going as well. This also requires a small Linux box - maybe an RP4 or similar. I could deploy the Zotac for this purpose, with the benefit of a proper i386 Ubuntu platform.

Total cost of this project is at least SGD688.65
