[SignalOne] 30M

[Anthony Clare]

Jerry,

The CX-7 works great on 60 meters too. You just need a 45MHz crystal, which
should be fairly easy to find.

I have mine on 30 as well.

All,

   Desiring to add 30M support to my CX7A.  The manual does not offer 
precise specs, so I punted.
What's the easiest and fastest crystal to obtain?  Amazon, of course:

https://www.amazon.com/dp/B0C38G144V

For the same price as two or three crystals from Mouser ( +shipping ), I 
got a box of 80 crystals, including 5 50-MHz ones.

They're the modern "short can" kind.  The pins are way too thin to plug 
into the socket, so I bent them
over 180 degrees.  The pins are fairly stiff, so - bent over - they fit 
sort of barely OK.

I plugged it in - no action.  Then twirled C77 and got a burst of noise. 
  Am now listening to WWV on 10MHz!

It only oscillated at a very short arc of C77's adjustment.  So I'm 
guessing that the capacitance is
not optimal.

Moved up to the 30M ham band, hit TUNE and got 110W on manual, no fuss 
no muss.

30M is important to me.  If you like CW, and you're NOT a contester, and 
you want to operate on a
weekend, 30M is it.

                  - Jerry, KF6VB
