I have similar problems when trying to use yaesu ft-857 and android phone. Jarec crashes if the s-meter setting is on, and there are many other problems. Sometimes I can't get more than a few watts from the radio with ssb, and when I store different frequencies in the memory locations, they don't always work, there are also many other problems. With previous old versions, ft857 worked without major problems. I first suspected that there was a problem with my own devices, so I tested with another similar program, RC FORB CLIENT, remotehams. It works perfectly, so the problem must be in this V.4.2 program. Are older versions available somewhere? is the jarec5 version coming?
