Can anyone tell me what crystal would be needed to put a d201 on channel 30? Thanks!

I believe 16.6085 for AM and LSB

That is for sure channel 30 for a tram 201? Thanks

The 40-channel D201A radio uses that crystal for channels 26-30. The D201A schematic at cbtricks.org has a crystal chart showing which crystal runs on each channel. You won't get channel 29 in a 23-channel radio. Just 26, 27, 28 and 30. Simple fix is to choose which four channels in a row you don't care about and swap this crystal for that one. Adding a switch to select the new or old crystal is mechanically awkward. If you run long wires to the switch, this will disrupt the crystal's oscillator circuit. A convenient spot for an added toggle switch will be too far from the oscillator circuit. Putting it close enough to keep the wires short will make the switch inconvenient to operate.
