Re: Need Help with a PL-600 and MTM Loop

It now works and you are correct.  While I did know to scrape the wire and did so the first time, guess I did not do it well or enough.  I simply used a knife the first time. This time I took some sandpaper and made sure I saw a distinct difference between the wire I cleaned and the rest of the wire.

Truly I think it was the end on the capacitor body that needed it most.

Thanks to all who offered suggestions and help

I have received many emails from people whose MTM loopa didn't work after they completed them, and in every case it was due to the fact that the wire is enameled and the enamel insulation has to be scraped or sanded off beofre the ends are soldered to the tuning gang. Many people miss's really the most likely thing that can cause it not to work.

I have placed the radio within the loop, pointed the long side of the radio at the center of the loop, and had the two antennae in a collinear fashion. Tuning the cap shows no improvement in the signal or distinct peak.
