Hi everyone,
Well, the Halli HT-32B is on the air. After many years of sleeping.
Changed the Electrolytics, 3 Black Beauty's. and the Bias diode (was selenium).
Also, someone before me had already SS the HV and B+.
Also had to adj. the carrier balance.
 
Working pretty darn good and WOW it is easy to tune-up.
 
One issue has surfaced...last night I was on 7139 LSB of course...and a guy came on and said I was 20 over on 7142 (above my freq)
I had several look at my signal and said it looked OK. But one had a Flex 1500 and helped me out. He said I was about 5KC wide and my signal went away at 7141.5 and went away at 7135.5.

I turned the Mic gain down some (to 2.0) and he said it was a little better but still pretty wide.
Today I had a couple guys on 7131 check it out as well and 4 KC was the width....I do realize these old crystal filters did not have straight skirts.

What should be expected on this TX as far as bandwidth and interference to neighbors??
What has other experienced?
73,
Lee, KC9CDT
