Here is a USA source of crystals for two of the 60 meter channels:
This is the location for KC9ON's 3rd Planet Solar site. He has crystals for "channel 4" and "channel 5" I have ordered those crystals (and other crystals from him) and the quality is great and his service is excellent.
I am not aware of anyone that has crystals for channel 1, channel 2 or channel 3 for the 60 meter band at this time. If you have a source for those crystals, would you please let me know? I would be interested in getting some.
