Hi Gary,

Thank you for the reminder....
It was quite some time when I (successfuly) played with 21cm receiver, using preamps from mini-circuits and spectrum analyser as receiver and data recorder.

The main drawback of that setup was power consumption... ~ 600W over couple of days/weeks for full sky scan resulted in notieably warmer room (and significantly higher power bill).

After that I purchased Nooelec dongle (with TCXO) to try low-power setup.

The plan was to use Spectrum Analyser software (freeware) which was quite powerful then (https://eartoearoak.com/software/rtlsdr-scanner).

Another app I tried then was very clumsy and basic, so I never really used it: (https://www.rtl-sdr.com/tag/spectrum-analyzer-2/)

I think it is now time to revive and continue with the project, maybe the newer applications are even better.
