Pete:
I like it! You and I may be the only people in the world with that kind of VXO range control switch on the front panel!
I checked my VXO. I run it at around 23 MHz. I use two single crystals, also switched by a relay.
The 23.144 rock tunes from 23.127 to 23.151 24 kHz
The 23.166 rock goes from 23.144 to 23.168 24 kHz
So I could have had 48 kHz were it not for the overlap. As it is, I get 41 kHz. Not bad.
The reason I went with this LO freq was that I had these crystals from the Dale Parfitt/Doug DeMaw Barebones Barbados Receiver. DeMaw had used color burst rocks for a 3.579 MHz IF, but Dale shifted up to 5 MHz. I could occasionally hear WWV! (But with the 3.579 I heard W1AW in the IF!)
