Just ordered new crystals and they arrived today. 18.432Mhz to get me on channel 2, 27.4688MHz for near channel 6, and 25.4563MHz for near channel 5. These are standard frequencies that DigiKey had in stock. About $2 a piece in oneies-twosies. I put in the ones for channel 2, and channel 6. The one for channel 2 is almost dead on, and the one for channel 6 puts me about 800KHz low. But closer than the 27Mhz crystal did (about 2.2Mhz low). These crystals are fundamentals, but I'm running them in 3rd overtone, which is close to but not exactly 3x the frequency.


You'll also notice that I trimmed the old tuner section off, just keeping the modulator portion. The two F connectors are tied together, and the modulator output connects to this link thru a 50 ohm resistor and capacitor. I can then daisy chain another modulator on channels 3 or 4 to this one. I need to skip channels, as there's no vestigial lower sideband filtering.
