I'm wonder if the PTT to CW delay also applies to FSK? Does anyone know this? It would seem that it would since perhaps both may be keyed from a serial port when using PC generates. Seems like it's the same thing only one uses DTR (CW) and the other TxD (FSK). Thanks... 73, Don AA5AU http://www.aa5au.com http://www.rttycontesting.com
