Title: sp-600 RECAP Post by: N9NEO on December 22, 2008, 12:05:16 PM Greetings AM brothers.
I need a link to the SP-600 instructions to recap the chassis. I'm down to 4 left of the ones I can see. Looking for the hard to find ones. regards, NEO Title: Re: sp-600 RECAP Post by: w3jn on December 22, 2008, 01:43:16 PM 54 total, Bob - good luck! Here's a nice article on this unpleasant task:

Theres a 50/50 chance that its burnt. I have done 11 of these from the JX-1 to the JX17 and 5 of them had a bad antenna coil.

Regards, Gary How does a bad antenna coil manifest itself in terms of operation? My JX17 has ceramic caps but I did have to dig into the rf deck for other reasons. I can't remember checking or even looking at the antenna coil - it's been a few years.

I have not seen this listed any where else. An excellent resource for most of the SP-600 manuals is at \\http://www.jamminpower.com:8080/jp/ AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
