I have a collection of 5 crystals for use in the Drake 2-NT, the Heathkit DX-40 and the Heathkit DX-60. I've used these 5 crystals in these 3 transmitters so I know they work in this equipment. Other transmitters most likely also. In 2012, I ordered 4 custom made crystals from International Crystal Mfg. Co. in Oklahoma. (ICM) They cost me $130 with mailing. These are 7005, 7014, 7030 and 7160 kHz. The other is an older crystal at 3596 kHz. On 20 meters the ICM crystals will double at 14.010, 14028, QRP freq 14060 and 14320. I recently sold my Drake 2-NT and now the crystals are surplus to me. I know someone can put them to use. $60. Mailing cost will be low. I'll package well for safe arrival at your location. I believe I can send to you in a big padded envelope for $4. E-mail or call anytime at 281-435-1733. Mike, W5MP.
