3275Re: [V4Protocol] Re: FSK CW ID
- Apr 30, 2013Joe,That sounds like a bug in the V4 CWID...it is supposed to drop back to ON OFF keying (single tone) if VOX keying is not used. The only reason you need FSK keying is to keep the VOX relay from chattering. Of course it only affects the ID and both ON OFF keying and FSK CW are legal ID.Rick
Thanks for the info. I'm using the Creative AudioPCI for audio transport, and a serial-port circuit (RTS pin with 2N2222 and a base resistor & diode) for PTT. I observe my latency to be between 30ms and 60ms when sending connection requests. What seems strange to me is that with the exact same hardware I get the two-tone ID on V4 but CW (single-tone) ID on Winmor. I have both software packages set up identically in terms of using CAT for frequency control and serial-port PTT control. I do not use CAT for PTT.

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.
