5MHz band soon - restrictions?

[Glen Zook]

As I mentioned the letter in the original post, you
can find the letter on both the CCA and CRA websites.
It is Service Information Letter 2-75 issued by
Collins Radio Group, Rockwell International.

It turns out that there are only a very few segments
of the 5.0 - 6.5 MHz range that cannot be used.
Fortunately, the 5.3 to 5.5 MHz range which takes in
the new 60 meter band is fine for all of the 200 KHz
band.  You need to use an 8455 KHz crystal in one of
the bandswitch position 2 (normally 40 meter) to use
the 60 meter band.

If you try to use bandswitch position 1, the receiver
works but the sensitivity is down.  However, the
transmitter will not work at all.  In position 2, the
receive preselector is between 1 and 2 and the
transmit exciter is around 1.  There are two peaks on
the final tuning, one near 1 and the other near 9.
You want the one near 1 since the one near 9 is the
second harmonic (10.6 MHz) and the final will
definitely "double"!

I number of years ago, I received a letter from the
folks who bought Collins (Can't remember the name
right now).  The letter stated how to use the S-Line
and KWM-2 on frequencies between 5.0 and 6.5 MHz.
