Thanks for all the suggestions and encouragement. I agree with WA6ARA that the bandswitch is a likely suspect. For the E socket on the Drake 2-B (that’s where my 22 MHz rock goes) the bandswitch switches in not just the crystal, but also a slug-tuned coil. It is presumed to be an overtone crystal. <\/span><\/p>\n

The receiver works fine on all other bands.<\/span><\/p>\n

I’ve already hit the wafer switch with several shots of RadioShack Contact Cleaner (I’m out of De-Ox-It). And I’ve given position E a good work out. No joy. <\/span><\/p>\n

I will dig deeper this week.<\/span><\/p>\n

It may be the crystal. It looks like I got it from Drake — it is marked “22 MHz 2C” so it may be for the 2C receiver. It has a sort of worrisome dent in the side. I may build the test oscillator that Steve recommends. <\/span><\/p>\n

Of course, as soon as I get this fixed the sunspots will disappear and 17 will become a white noise generator. <\/span><\/p>\n
