[Motorola] Syntor X

[John Jewkes W6HNC/AAR0MI]

Hi Paul,
    The Micors, should be worth about $40 each IF they have the elements 
for the Crystals (ICoMS) inside, otherwise about $5. The 412 MHz will do 
FB for MARS and HAM frequencies. To verify operation, they will need to 
be spec'd out using the shop manual.
    Syntor X is a little more difficult to value. The PROM that the Syntor 
X uses for Frequencies and PL tones/power output levels is no longer 
available from Motorola. IF he has any blank prom chips, then it is very 
valuable, and the chip values can be burned into prom by anyone who has 
a chip burner (MANY ham's & ham clubs either have or know of someone in 
the electronics industry with a chip burner/access to one.
    OR-- their is a ham who has made a retrofit kit to make the PROM into 
an EEPROM system, programmable on the fly via a laptop or desktop 
computer. Google for 'Syntor retrofit' as I don't have his callsign off 
the top of my head. If updated to the EEPROM, or blank PROMS available 
probably $75 /$10 without. Syntor, Syntor X are both very cool running 
finals at 100 Watts continuous, and very stabile oscillators (Nominally 
.002 PPM equivalence vs .005 PPM for other makes/models of the same 
vintage. Only MSR2000, also by Motorola, beats them, as the Base/
Repeater MSR 2000 will normally run at 300 Watts +/-.
