Re: [Drakelist] Vox not holding on TR4CwRIT running CW.

Hi Michael,
 
Have you adjusted the VOX delay time and VOX Sensitivity? As far as SSB goes
maybe you have to turn up the MIC gain? Just a couple of thoughts. Good
luck!

Hello everyone - 


I have a TR4CwRIT that will not hold once it switches from receive to
transmit, running CW. It sounds like I am running QSK full break when
sending ... after turning up the sidetone to make sure it was loud enough



I have substituted (one at a time) the:


1.  V-2 The sidetone oscillator 12AV6


2,  Then the 9Mhz Xtal Oscillator V-16 (6GX6) 


3. Then the VoxAmp/Relay V-19 (6FQ7) also tried using the earlier used 6EV7


4. Finally the V-17 Anti-Vox 6AQ5A


Each time nothing changed, I put the original back, trying to eliminate
extra variables  and while some guys may want to try and get a TR4CwRIT
to run QSK ... with the relay cycling so rapidly (between dits) I don't care
for it at all, not to mention the workout for the relay.


Anyone have a suggestion?  

PS One other clue is when I try to operate using the microphone, I am
getting a normal vox relay change over that does not fall out and cycle back
to receive, but I get no drive when whistling in the microphone ... so it
keys up to transmit mode seemingly perfectly normal, but regardless of my
drive setting I get no deflection on the meter to indicate output.  BUT I do
get normal output when using a key in CW mode ... just does it in QSK
fashion.


Thanks everyone ... I am stumped.
