Further to your comments
What comes next is quite another story. Linrad does not know
what you might want to do with your Perseus hardware. Do you
want to make a 24 hour waterfall just to look at or do you want
to make measurements on the spectral purity of a transmitter?
Perhaps just listening to AM stations on HF - but maybe you have
QRN that could be removed with the Linrad noise blanker? You might
want to improve S/N on frequency unstable microwave signals
by use of AFC and a narrow filter or perhaps you want to
send data from Linrad over the network so you can run
several instances of Linrad to process several narrowband
I think that in order to make LINRAD more user friendly you should
make more interfaces, each one specialized for a certain purpose:
- receiving weak EME signals + removing local QRN;
- working in VHF contests with strong QRM + removing QRN;
- receiving VHF signals from a converter + SDR receiver and slaving a
separate transceiver for transmission.
- receiving HF signals;
- listenening to HF AM signals;
- using it as a spectrum analizer;
- using it over network;
- making a 24 hour( or whatever time)waterfall to look later at the
activity in the spectrum
every interface should have all paramenters set up for the specific
purpose, which could be slightly altered later by expert users.
In this way the program will become more user friendly as the normal
user has to chose only the receiving device and type of interface for
his specific purpose instead of setting a lot of parameters.
Thanks for your understanding,
