5/2/2012 8:13:52 AMElton
Hi all want to align this radio, have the directions from riders 15-34 but they are vauge. it does not tell you where to connect the sig gen for each adjustment. just how to set the dial and where to connect the output meter. Anyone have a little more detail on this procedure?
Thanks

This radio is aligned the convention way. For the IF alignment connect output lead of signal generator though a .01 capacitor to pin 8 of the 7F8. Negative lead to chassis ground. Adjust 2nd IF first, then 1st IF. Keep signal generator output as low as possible.
To adjust antenna and oscillator trimmers two turns of wire to make a loop connected to signal generator. Place this loop close to the radios loop antenna. Adjust the oscillator as per info, same with antenna trimmer.
