Thanks for the responses regarding my crystal needs. One of the links led to a company that had the 24.5mhz in an hc-6 can but it was priced at $30.00 + shipping + tax. That made it a $40.00 xtal!

I found another way that was super cheap and is actually a better solution.?

A while ago when I was restoring my Drake 4a, I ran into the same issues looking for extra band xtals, so what I did was to purchase xtals in hc-49 cans which had leads. I then cut some sections od PC board pads previously purchased from QRPME. Using an hc-6 xtal as a pattern, I drilled holes, cut pins from rods purchased from Ace Hardware, soldered the pins to to the PC board, and then soldered the crystal to the pins. After I checked them out in the receiver I potted them in 5 minute epoxy.?

Now to the Drake 2C. I remembered that I made a 16 mhz xtal for the Drake 4a, and figured that one of the harmonics would be 32 mhz. Subtract 4 mhz, and you are at 28 mhz which is the bottom of the 10 meter band. I plugged it in, switched the 2C to 10 meters using the xtal calibrator, peaked the preselector at just below full clockwise, and it worked!? The best part is it now tunes up using the main black tuning scale instead of backwards using the red scale.?

I checked everything out running my Ten Tec Argonaut V into a dummy load while listening on the Drake 2C.

These hc-49 crystals are dirt cheap costing about $1.00 each from the many electronics suppliers, and even cheaper from Aliexpress. If you make a few band crystals, by the time you are done, it will probably cost you about 2-3 bucks each.?

I plan on buying some more to cover other bands.?

I hope this helps others.
