- Apr 29, 2013Joe, All,The keying methods for WINMOR and V4 are similar. There are several possible methods.... any will work when set up correctly.1) VOX or VOX type keying. The virtual TNC adds a longer leader to allow the transmitter VOX (or in the case of a sound activated PTT like on the SignaLink USB or similar interfaces) to key the transmitter. If using the SignaLink you MUST have the PTT output wired to the radio and you MUST keep the DLY control fully CCW. For Transmitter VOX you should have the VOX hold or delay set to minimum.2) Using a the DTR or RTS signals of a dedicated serial port. This may have to be level shifted or go through a relay to key the transmitter.3) On those radios that support “CAT PTT” the software will issue a PTT ON/OFF command to the software.The Help should elaborate on these methods and how to set them up.The acid test is to look at the T>R latency as measured when calling for a connection. No matter which method you use the latency must be < 250 ms.73,Rick KN6KB
Joe. I observed on the RMS Express using Winmor, and on RMS Trimode. Did not so far check on myself on V4. We need inventor of both, Rick, chiming in.
I believe the soundcard and way of keying is part of the issue.
