To get to channel 40, you'll need 3 crystals. You'll need a 12.000 mhz, a 12.050 mhz, and a 12.100 mhz crystal.
The 12.000 crystal will get you 26, 27, 28, and 30.
The 12.050 crystal will get you 31, 32, 33, and 35.
The 12.100 crystal will get you 36, 37, 38, and 40.
The clarifiers on these old radios can slide into 29, 34, and 39 without too much fuss if you know what to do.
Remove the 11.7000 mhz crystal, which is channels 1-4 on the dial. You can either swap in any one of the 3 crystals above to get hose channels in place of 1-4. Or, you can put all 4 crystals on a switch, and solder leads from the switch to the socket where the 11.700 crystal goes. Just make sure if you use a switch, to mount it as close to the crystal socket as you can, and use the shortest leads possible. Using this method, you can have 1-4, as well as the above listed channels.
I have a photo that illustrates what I have done on another radio. I have done this method on many 23 channel SSB radios, and it works pretty well. The clarifier might not always be on center slot with every crystal, but if the crystals are cut properly, there shouldn't be much variance. Good luck!
This particular radio is a Midland 13-893, and with the crystals it has, it has continuous coverage from 26.965 to 27.555, as the clarifier slides to get all the "in between" channels.
~Cheers~
