Re: TR-4C Problems with 28.0 and 28.5 bands


 

Well, this morning it's behaving normally and I was able to set the BIAS with no problems. Strange! I'm hearing lots of stations on 28.0 and 28.5 bands this morning but nothing yet on 29.1. I can hear my signal generator up there so I know it's working, that part of the band just isn't open yet or there's nobody up there. The can cap (C145?) has been replaced with individual caps by a previous owner.
Current problem is Xmit on 21/28/28.5/29.1 bands. It will tune up but when I key up the mic I don't get an SSB output. It's a strange output, it will send a very brief output on loud voice peaks but nothing on lower volumes. This is with the Xmtr gain all the way up and a hand mic that works just fine on 80/40/20. What output I do get when tuning up is about half of what I get on the lower bands.
73, Dave
