Re: [Drakelist] R4C Hum and audio transistor

Hi Max, I replaced the original audio amp in the R4C with a Velleman audio kit board with an TDA2003. The Velleman kit # K4001. I believe I paid around $ 15.00. Works great. If you're interested I can send you pics. 73 Bert, VE3NR _ From: drakelist-boun...@zerobeat.net

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! 73 Bert, VE3NR _ From: drakelist-boun...@zerobeat.net [mailto:drakelist-boun...@zerobeat.net] On Behalf Of Michael
