The software I am using is SDR# and soundmodem.

The band supplied is 150-170MHz and I was wondering how hard and fast that range was.I'm going to do more research myself but if anyone knows or has used something similar that would be very useful.

I have found modules for 433MHz band but I need to design a circuit for ~169MHz (VHF band).I'm unsure of the matching circuit and which components to use.Any help would be greatly appreciated.

I used a GNU radio flowchart and was able to decode the messages sent.

I am trying to decode S2LP transmission using software defined radio. I am able to transmit between S2LP devices but the message is not being decoded by my SDR. Any help from anyone with experience would be great.

Will I be able to program the SPIRIT1 to receive at about 144.3MHz?

I am looking for reference circuit designs for the spirit1 low power sub-GHz transceiver. The data sheet is limited and the design references is no longer on ST. Does anyone have more information about layout and setup?
