Hello all, Just got the 2 meter unit hooked up. This is a factory built unit. The keying polarity is opposite of what it says it should be. When I tune using the mouse wheel, a relay clicks proportional to the mouse wheel's motion. I tried changing the polarity as well as TX enable in the transverter screen, but nothing cured it. Thanks for any help. Paul WA3GFZ

I subsequently found that the TX RX B+ lines were wired backwards at the DEMI factory. So much for testing before shipping. But the relay is still clicking due to noise induced by the parallel port.
