You also have to add trimmer caps to the crystals in order to "net" them in to the exact frequency. But you have to keep lead lengths short to keep the crystals close to frequency. 11.400 will give you 36,37,38,and 40.Īnd yes you could put the crystals in a little box with a rotary switch and mount it to the radio. Channel 24 you can get in the blank spot between 22 and 23 (I don't remember whether I put it in there or not).Īn 11.300 Mhz crystal will give you channels 26,27,28,and 30. It would be one of the channels you skip, every 4th channel due to the RC gap. Channel 25 is below channel 23 in frequency. You're pretty darn close, although your channels are a bit off. Hell i dunno i think i am starting to confuse myself LOL Like if i was to replace JUST the 11.000 crystal in the first position with a 11.300 crystal it would give me channels 25-26-27-28 on the 1-4 positions on the channel selector. So if i am thinking correctly i would need to replace one crystal with the box then i would have four new frequencies on those positions of the channel selector right? Its a group of 6 "channel" crystals and the 3 different oscillator crystals as shown on the chart. Set the box on say position 1 then use the actual channel selector to chose between the 4 frequencies for that particular crystal right? I should be able to run 6 different crystalls with that right? I'm eyeballing the 6 position 2 pole rotary switch at rat shack for this a 11.350 crystal set on position 2 of "the box" would give me channels 29 30 31 and 32 and etcĪnything special i would need in the circuit? or is it ok if i just ground all the ground legs of the crystals and use the switch on the hot side?

Like 11.3 will give me channels 25 26 27 28. 05 in frequency would give me a new "group" of 4 chennels each? Here is the crystal chart for the radio now am i right in thinking that each.

Thats almost exactly what i was thinking.
