4,789,980 cycles per second. How do I align my dx 394 so it is in better
alignment ? My receiver can go down to 100 cps.

I developed a technique for aligning the 4 oscillators of the DX-394
using only a 25kHz (or lower) harmonic marker generator, a software
audio spectrum analyser that reads audio frequencies accurately and my
ears. It's described in the DX-394 special interest group at
http://groups.yahoo.com/group/RADIOSHACKDX394/. With a modification to
the 2nd local oscillator, I achieved an accuracy of +/-100Hz across
the entire tuning range of the DX-394. For AM reception, you don't
need this kind of accuracy but it's a great help with SSB.
