Thank you Stefan (and all),

I think I will put the FCDP+ at the top of my list for now.

Regards software. This has been a bit hit and miss with me for SDR's.

I like SDR# but it is Windoze only. I prefer Linux but use Windows when 
have to. On Linux I have been using GQRX. They all have their pluses and 
minuses but the challenge becomes getting everything to place nice 
together, for example which OS? I like GPREDICT and there are Windows 
and Linux flavours but the FCDP+ software is Windows only (or is it? I 
will have a go look see).

I guess it is time to do some more reading and research.

Glad I didn't get a HackRF.

cheers, Graham ve3gtc
