Is there any fundamental reason why I can't use VOX control while running
PSK with my K2? I've never used VOX with this rig on SSB, but I assume it works okay. I recall much discussion about lack of mic gain not triggering the VOX, so I'm wondering if that is also limiting what I can do running digital modes. If so, I'll stick with PTT.

Parker,
The K2 VOX does not work well with PSK - by the time the audio is cranked up enough to trip the VOX reliably, you will be driving the audio input too hard and the transmitted IMD will suffer. The VOX in the K2 works OK for voice, but not as well for the more steady audio tones of soundcard digital modes, so I recommend you stay with the PTT operation - since you apparently already have that working, I see no advantage to change. The K3 VOX OTOH is very smooth and will work quite well for afsk data modes. 73, Don W3FPR Parker Buckley wrote: > Is there any fundamental reason why I can't use VOX control while running > PSK with my K2?

Don,
Thanks for the quick reply. I expected you would jump on my question! I'll stick with the PTT setup. I'm looking at options for going portable with a laptop, and VOX may have made that easier. I hear you about the K3. I keep looking at my Hallicrafters gear, thinking I could turn that into a K3 at the next Hamvention.... 73, Parker -----Original Message----- From: Don Wilhelm [mailto:[hidden email]] Sent: Monday, October 27, 2008 9:51 AM To: Parker Buckley Cc: [hidden email] Subject: Re: [Elecraft] [K2] VOX on digital modes?

Suddenly lost my NR ability in my K3. Just getting N/A regardless which filters are in or if NB turned on/off. Using latest F/W 02.57 Any hints, someone, please.
