[Elecraft] A->B mods

[David Kearns]

I've just started the A->B mods and found that I had
problems at 7MHZ.  The following may help others:
The freq. is never exactly the same, but is very close
(within .5kHZ)

To find if you have a problem tune to the top or
bottom of the 5kHz section where the freq is very
similar.  By changing the freq by 10Hz across the
boundary, you will hear a distinct change in note to
the RX signal.

I used a DDS to produce a CW note to listen to, but
any signal will do.  If you have a problem it is very
obvious.

Hope this helps
