Default Re: 20.431 Mhz Crystal wanted

In the last year I've had the guys at QuartSlab - - cut some crystals for me - these were 5.mumble MHz ones to put my AEl3030 transceiver on 3.6/3.7MHz but they offer a good service - the crystals mthey did for me came up mwithin 100Hz of the target frequency and have not gone-a-wandering frequency-wise over the last half-year [drifty crystals were a bit of a probllem with some suppliers in the 70s and 80s - a 250Hz drift when multiplied x32 or x36 in a VHF/UHF transmitter could put you on the next-channel-up!]
