Hearing busy van to dispatcher comms on 29.790 MHz and 31.120 MHz, mobiles signing on and off with dispatcher, solid SIO 555 S9 signal on the COMMSIGMA KiwiSDR located on the CT/MA border. 31.120 is the most active frequency at 2050 UTC. Looking at the waterfall for 30-32 MHz I am seeing other FM signals, although they are much weaker than the Van Pool repeater network under licenses WQMA652 and WQPU857
