If the multiplying scheme for 15m on the Valiant could use 40m crystals X3 then there are many possibilities.
7150 will put you right on 21450 kHz and I have plenty of those available. I also have several on 7140 kHz which will land you on about 21420 kHz. Add a little ink or pencil lead and bingo, you easily get down to 21400 kHz which is the AM calling frequency. Anyone want them? 73 - AF4K, Bry > Hey Jim, > > Thanks for the tip on using a 6.050 crystal for 17 meters. Interesting idea > for sure.
