Gang,

The Delco 5300A is QRV on 7030 KHz.  Well, 7029.809 actually.  A little 
600-grit wet-or-dry moved the WWII 7025 rock without a lot of drama.

Contrary to popular belief, it's possible to use FT-243 crystals in 
these things.



The receive crystal (front) is foam taped to the chassis.  The transmit 
crystal is tied down to a resistor lead.



D-subminiature (RS-232) pins are a perfect fit for the xtal sockets, and 
octal-tube-socket contacts grab the crystal nicely.



Next step is to make some computer cables in an attempt to make up for 
my atrocious Morse skills.

How would people feel about a once-a-week experimental radio 
get-together in the evening, probably below 3800 KHz?

VY73,
Al
