[R-390] 200Khz marker Crystal

[Flowertime01 at wmconnect.com]

Fellows,

As pointed out in other mail the 200Khz crystal for for the marker is hard to 
find.

Push come to shove, you can open a crystal can with the trusty solder iron.
The old inards can be removed by heating the pins and extracting the wire 
lead.

A new small 200Khz marker crystal can then be installed into the old salvaged 
pin base. With luck and care the old can top can be soldered back on.

As the circuit has a cap adjustment to pull the frequency into alignment all 
the way to the 320 or so harmonic, most any crystal marketed for use as a 
marker crystal will function.

You need not open up a 200Khz can. Any can will work. It may be a 200Khz 
crystal and have a cover stamped with what number.

I did a 455Khz can that way for the .1Khz IF filter. I simple ran some solder 
over the can top to cover the original stamped crystal value. So when you 
look at the can in the IF deck it has no value displayed. 

At least when you look at it you see a can with more solder than expected and 
are not looking at some thing marked 22Mhz and wondering why its stuffed into 
the IF deck.
