[TowerTalk] messed up wiring to key my amp

[terry burge]

Thanks Keith,

Working on that right now per Kelly's suggested just checked the impedance on the 'Key Out' which is alright. Going to try that again. The only time I figure on using VOX is when I do CW on the K3 so that is a possibility. VOX just never was something I had any luck setting up not to mention noisy bands.  Also got a new cable that checks out good for running between the K3 and the amp relay. And trying to stay positive about this. Not easy after losing my P3, two watt meters and amp keying after just trying to clean up wiring. I'm never good at doing a good job with running this wiring it seems. 

Thanks,
Terry
