41-290 Alignment
#1

I'm in the process of redoing a 41-290. I've got the electrical portion pretty well finished. The AM band picks up a few local stations quite well. The other two bands pick up several transmissions, but they are rather garbled. I suppose that the transmissions are SSB. I have the schematics and other service info that I had ordered from Chuck which includes the alignment instructions. I don't have any access to any equipment like a signal generator and I don't really want to go out a buy one as this is pretty much a one-off project. Is there a simple procedure to check the alignment without having to resort to any test equipment, or should I just leave well enough alone since the AM band seems to be working quite well?

I haven't had the radio powered up for too long yet to really check it's performance. Also, my work area is right next to the main power panel which does seem to have a big effect on the little AM/FM radio I have out there to listen to when I'm working. Should I move the radio to a more "RF friendly" area to get a better idea of it's performance?

During the electrical restoration, I had several question come up which were answered by the kind folks at this site that were a real big help.

Thanks!!
