A short video showing the DVPR in use. The IC-910 is being controlled by a very low cost PIC and about 10 lines of code for detecting RX signals, PTT control and switching the RX/TX frequencies (using serial CI-V commands) between the MAIN and SUB bands depending on which band a signal is detected on. The IC-2820 is being used for chatting in DV mode. This test was with Bob G1SAA who was TX'ing on 144.6125Mhz and being rebroadcast locally on 438.6125Mhz with no problems at all.
