Dittel radio squelch

The squelch on my Dittel FSG 50 has got to the point where it lets a lot of noise through. After a search of the Internet, I have found many allusions to the fact that this can be adjusted with one of the internal pots, but cannot find any reference of which one to actually turn. I've attached a link to a picture of the inside of my radio and I'm hoping that one of the many technical minds on r.a.s can tell me which one I should adjust.
Thanks in advance for the help.

There is a good chance you don't have a problem with squelch at all, but you do have a problem with interference from all the other electrical devices in your panel. Your radio is doing exactly what it is designed to do.........present a weak signal for you to hear! If you turn down the internal squelch, you will also be denying any and all weak signals that everybody else is hearing. What other instruments do you have in your panel and how close are they to your radio? Try turning off the other instruments,one at a time to see if your radio stops breaking squelch.

Sounds reasonable, I guess the next questions are...
-any new devices added?
-any wiring recently moved?
-any devices moved?

I would start with the new stuff, work backward from there.

I ran into problems with an inexpensive DC/DC converter (12v to 5v for USB). Lots of the electronics we use generate noise. The cheap converter broke squelch so badly the radio wasn't usable. Solved the issue by getting a different converter unit.

Good luck,

I also was getting a lot of breaking of the squelch with a cheap 12V USB converter. I later used a Dell adapter like the one that came with the Dell Streak and it was very RF quiet.

Since I installed my Flarm Red Box I also get a lot of interference. I adjusted the squelch pot a bit. You should be able to Google a manual. I tried various ferrite chockes, but they didn't help.

I have had this problem and there is a pot that will adjust the squelch
issue that you are having.Your picture covers up this pot by those yellow
straps.I believe I can find a diagram that Karl sent to me years ago.If so
I will notify you.

I'm having the same problem with mine without any converters in the circuit and am interested in trying the squelch adjustment. Thanks for the help.
