[Elecraft] KDVR3 Firmware request

Do I understand if I am in PTT (not VOX) and I hit M1 the DVR will 
transmit(actually act like it is on VOX although the K3 is set to PTT?

What about if I have used PTT with a foot switch and keyed the K3 and 
the 8877 on two meters and the T/R relay in the amplifier has been 
switched can I tap M1, etc. and send the DVR CQ or other message?

If this is true I can make this work.  Obviously I have to be sure to 
activate PTT with my foot switch before hitting M1, etc. or almost 
certainly burn up the T/R relay trying to "hot switch" 1500 watts.

If this works then I would assume even if I take my foot off the foot 
switch the DVR continues(simulates VOX).  I certainly need to keep my 
foot on the PTT switch until the DVR is finished to prevent burning up 
the T/R relay if there was a simulated VOX drop out.

So another question if you are in PTT and you hit M1 and it starts 
transmitting(simulates VOX) does the VOX settings such as delay in 
effect.  I have a hard time getting used to things doing VOX like action 
when you are in PTT.

You answered my question about CW on SSB in that you can defeat it 
sending CW when in PTT.  I never have read the CW Weight item as I don't 
mess with that on CW so thanks for telling me where it is at.  It 
surprised me the other day when I was in SSB with VOX off and I 
accidentally hit the CW key and tripped the protective circuit on the 
Alpha 99 as the amplifier was not set up as I was just listening around 
on different bands thinking since I was not in VOX it would not transmit.

It is a nice feature to be able to transmit CW when in SSB mode and the 
menu item handles the situation well.  I normally will have it so it can 
not send CW but over the years I have seen times where this feature 
would be nice.
