Hi all,

I am new to this forum and basically I googled to get the best gps-repated forum out there, hence I am here to ask a question.

I have a few RTK GPS Instruments in which basically a base station broadcasts its correction data via a Radio Transmission medium.

Currently, I am using HX-U202 Radio which supports a frequency band of 450-470MHz.

The problem I am facing is with the receiving nodes of the data, called rovers. Their radios (Satelline perhaps) have malfunctioned.

I am looking for an option to get a open source / software defined radio hardware which would be compatible with the link protocol of the HX-U202, which is Trimtalk.

Is there a way to get a general 1 watt receiver and implement Trimtalk protocol somehow to receive data from the HX-U202?

Or maybe another suggestion? Where would you advise to get started?

I'm sorry to say it, but you are probably better of in a forum like Stack Exchange. It's full of people who love answering questions like yours.
