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! 73 Bert, VE3NR _____

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. Michael NZ4D
