[RTTY] PTT From Where?

[Ken Alexander]

I'm planning on operating in the BARTG RTTY contest for a few hours this weekend with my K2.

I will use a MicroHAM CW Keyer as the interface for rig control and a SignaLink USB as the audio interface.  I'll be running N1MM and MMTTY software.

Both interface boxes are capable of controlling PTT on the K2 (the CW Keyer via the I?O port and the SignaLink via the mic connector), but it makes sense to allow only one of them to do so.  The question is, which one should be allowed to?  My first inclination is to let the microHAM do it because it's a "rig control" function.  Does that make sense or does it really matter?

Thanks and 73,
