[Hammarlund] HQ-215

[Dan Cotsirilos]

Note of interest that maybe HQ-215 owners already know. Up until 12 mc the HQ-215 uses the exact same crystals as the Collins S-line. I happen to have a crystal pack and the crystal freq's are the same as the 215. After 12 mc the Collins uses double overtone and the 215 uses triple.

The filters are the same 1/2 the crystals are the same triple vs double is a funny place to make a distinction?
