Good Morning All:
Playing with a nice TR4 here and wondering if there is a way to extend
the delay when using CW mode. I see very little difference from CCW to
CW on the VOX control in CW although it works fine in SSB.
Would like to lengthen the drop out time without messing up the VOX
Curt -
VOX delay is adjusted with R106, which is selected at final test. It is designed for SSB, as is the
rest of the TR-4. You _might_ be able to find a value that is a reasonable compromise over the
narrow range of adjustment provided by the VOX GAIN control, but ...

I feel your pain on this problem. What I finally did was follow a little
paragraph ditty in the TR-4C's manual (and Ron Baker's suggestion) and
added a small manual on-off switch plugged into the mike socket. It works
I have found that to get the CW delay that I prefer, increasing R106 above 3.3
meg is not enough. In fact you will reach a point where the VOX will hang. I
suggest replacing C143 with a .47 ufd capacitor and then experiment with values
for R106. You could instead mount a pot in an unused hole
