Zenith H500 Trans-Oceanic
#27

I'm curious if anybody has had difficulty aligning the H500's "spread bands", 19m & 16m to be specific. The other bands aligned OK.

If I recall, these bands have only one adjustment and are aligned at the center frequency. The two H500's I've restored these seem to be off quite a bit on either side of center.  Not that there's much left to hear on those bands these days, but it would be nice if WWV was at 15.0 on the dial Icon_biggrin.

I have to check, but now that I think of it, I may have aligned one of them at 15MHz.

I have another H500 and 2 or 3 other TO flavors in the queue...

Can't think of anything witty.
