[Elecraft] KDVR3 Firmware request

[Ed Gray W0SD]

Thanks Lyle!  For me that is great news!

I have another question on the KDVR3. If I am using PTT rather than VOX 
can I play a DVR message by tapping for example M1.  Let me explain 
more.  A long term problem with VHF contesting and using DVR on two 
meters and above is hot switching the amplifier T/R relay at high power, 
ie 8877 on two meters.  By and large people use PTT and even then in 
some cases a sequencer to be sure the amplifier T/R relay has to be 
closed or at least gets a head start at two meters and up.  If you use 
DVR on VOX you soon burn up an amplifier T/R relay at Two meters and up 
unless it is an expensive vaccum T/R and I have seen them go!

With the KDVR3 I am wondering when using the K3 with a XVERTER if one 
can key it and the amplifier it is driving with PTT and then play the 
KDVR3 message tapping the M1, etc. key.

I am assuming if the VOX is not on the KDVR3 will not key up the radio 
if you accidently hit M1, etc.  However I am wondering since in USB or 
LSB you can send CW even though the radio has the VOX turned off. Put 
another way you can not transmit with the mic until you engage PTT but 
if you hit the key it still works jsut like VOX.  Maybe there is a 
setting where that can be defeated but if so I have missed it?
