[ARC5] Crystal Alternative

[David Stinson]

I've used them in many places with good success.
Often use one of those 75-cent DC-DC buck
converters to supply them from either A+ or
rectified filament power.
Used these from Digikey for most projects:

My SCR-274N VHF
receiver listens to local aircraft traffic whenever
I'm in the falling-down cluttered barn corner I use
 to melt solder.
All four channels are little prog-osc boards.

A sweet little Forest Service radio needed a receive
crystal I didn't have, so a four-pin osc. went into
an FT-243 case.

Couldn't find the right crystals for two Receiver
channels in a BC-669 so:

Was also missing one for a Transmit channel
and it needed more "umph" than receive, so:

If I can get the right crystal from Bry, I sure would.
But these will do when a crystal just isn't available.
