[Boatanchors] Solid state crystal calibrator circuit needed

[Radios R. Me]

Greg - there are a number of circuits out there.
Some of them use a standard tall hc13u crystal on 100 kHz while others use a 
higher frequency crystal 

and divide it down to 100 kHz.  To me, I prefer the old way with a standard 
crystal, although oth will probably do OK.

The simplest method would be to use a transistor in a Pierce oscillator   There 
are numerous articles in 

the later ARRL publications and 73 Magazine articles etc.

Another good example is to look at the manual for a radio like the Yaesu FT101 
series or the Kenwood TS520,
since these used a solid state 100 kHz calibrator with the traditional 100 kHz 
crystals.
The manuals for both are freely available for download on the web.  You can 
easily replicate those circuits 

with readily available parts and the designs should be most reliable./

Any inductors you use will need to be large enough to make it run at low 
frequency.

If anyone needs a 100 kHz crystal, please e-mail me off the list.

Hi:


I'm looking to build up a 100khz crystal calibrator for my SBE SB 34.  I'd like 
to use an MPF 102 fet and an HC/6 tall boy crystal at 12 vdc.  Got all the parts 
but no road map.
Thanks
