DATV-Express SSB / FM Radio Transmitter

Post by G4GUO » Tue Sep 12, 2017 3:01 pm

Terry G1LPS asked me to make this available.
Copy it to a folder and start it up!
What is it?
It is a simple 70 MHz to 2.4 GHz all band SSB + NBFM radio transmitter for DATV-Express
that I wrote 2 years ago. It uses constant envelop SSB.

No warranty, no worries!

Little know fact, you can use DATV-Express with GNU-Radio

Hi Charles,
GNU-Radio is a bit of a beast to run portable or on the bench for setting-up...
Now you have the hardware abstraction layer clear in your mind.
Please have a think about supporting the SSB / FM Utilities on the Lime and Pluto boards too..
Happy new year.
Dave

Hello Dave,

I thought I would advertise Alex's OZ9AEC work as he did the port some while ago
and I doubt anyone other than me has tried using it. Looks like I am going to have to
bite the bullet and figure out using GNU-Radio for DVB-S2X soon myself as I need to do
some receiver testing. My biggest problem is finding space for all these wretched
computers!

Have you tried SDR Angel for Lime/Pluto? https://github.com/f4exb/sdrangel

I think Mike G0MJW has used it on a Windows machine.

I did and it worked. The interface is a little strange but OK once you understand it.

Gnuradio works on Windows too - sort of.
