I have a transmitter site that needs an RS232 data link for the remote control. We have a 950mhz STL (Moseley 6010) going to the transmitter and a 950mhz RPU return channel (Moseley 6010) coming back to the studio. I am looking for a simple, affordable solution to send and receive RS232 data via the STL/TSL subcarriers. I'm not really interested in IP-based solutions and there are no copper lines at the site, so phone lines are out. It's STL or nothing. Any ideas?
