Well after getting everything connected I had a little bit of success.
I came across some blips on the spectrum, looked the frequency up on google and found that it was a pager signal (POSCAG). Another quick search on google for some decoding software and I hit on PDW. The picture shows PDW (top) and HDSDR on the bottom).
I'm debating wether or not to put a Diamond X30 2m/70cms co linear up in the loft and use this as my sdr antenna as it basically covers upto about 500mhz. The NewSky TV28T covers from 20mhz to 1800 Ghz) any comments welcome.
