That's exactly what i was after and then some, very comprehensive..thank you. I'm about as far south of the equator as 4 F1 gets and the patch does a fair job, looking forward to trying this.

Re: diy biquad for inmarsat

Great job! I have the same dish but running the patch antenna. Could you post some dimensions and maybe a straight on shot of the solder join? Thanks.

Re: Signal Identification Help

I believe that those are SCADA signals. They send data from all kinds of monitoring devices from storm water to gas etc. Quite prominant in a number of bands with good signals. They almost always are proprietary for the purpose and difficult to decode.

Re: op25 (police radio)

It's been a few months since i used my op25, but from memory, there are keys (poss. the arrow keys) that allow for live fine tuning. Have you tried those in conjunction with the phase plot?

I'm in no hurry, i understand the need to design these things correctly. In the mean time, i will still pick up a vivaldi to play with.
