RE: [TenTec] "PTT CW" vs. PTT-controlled CW redux

["Richard Detweiler" <rdetweil@hotmail.com>]

Scott:

Thank you for your post.

And thank you for listening.  Spriit is taken as intended.

You are right about the issue that if a modification is done to force the 
relays to TX and mute the audio,  It would require a manual switch to take 
out the PTT control and put the radio back into QSK mode.  Not a great idea 
but again, do-able.

It is sometimes hard to express what the real problem or functionality 
desired is.  Thus leading to confusion in terms.  Between us we have an 
understanding of what is desired.  We should probably come up with a better 
term for what is being described.  So a clarification of what is wanted and 
what can be done would simplify the discussions.

I'm not the spokesman for everyone,  but I can say what it is I'm looking 
for.  In CW Mode, when the PTT line is lowered or closed,  the antenna 
relays would go to TX position and the audio would be muted, that's all 
that's needed,  The CW key would then do the rest as normal.  When the PTT 
line is raised or opened,  the radio would revert back normal operation.  
Any Transmit operation would always 'override' the PTT line so if a change 
occured in the PTT and it went open and the transmitter was still sending a 
dit or a dah, the PTT line would have no effect until the tranmistter 
operation was finished.  If the PTT line opened and there was no transmit 
operation, then the antenna relays would revert to RX and the audio un-muted 
immediately.  If this is what MOX PTT is, then that may be a good term to 
use.

It would be great if it was something that could be field upgraded.

Again, Thanks for the discussion.

And appreciate you talking with me over the phone so many times.
