[222mhz] Spectrum 220 transmitter

[Chris Boone]

I had two other replies, Brian...both had the same ICM part number (and
different from yours!....I think it ended in a 020...Anyway, I sent that
number to ICM and they replied back with a 18MHz fundamental (Im  on
224.500) and everything looked right..Have two Spectrum SCR200 220 rcvrs now
(not including the rptr!) for sat rcvr use..one already has the 222.900 rock
in it..just need to order some more ;) and then add the UHF links and
voter..

 

Thanks for the reply...I am kinda curious why the different part #s.but
Spectrum was not a good customer with ICM..they royally  POED ICM back in
the 90s over a 1million dollar deal of 900MHz paging xtals..and ICM swore
they would not deal with Spectrum again..so their paperwork is a bit out of
date it seems!

Hi Chris,

I don't subscribe to all the other groups, but I did not see an answer here.
I show the ICM catalog number as 00845192 and 00845192E. My latest TX
crystal was the E suffix and was ordered in 1994 (yikes!). Example
fundamental frequencies are 18.715000MHz for 224.580MHz and 18.706666MHz for
224.48MHz. Spectrum listed the transmitter as "2204-A, C TX".

The matching receiver catalog number is 00845195(E) with a fundamental of
about 58.4MHz (222.980/58.420).

Again, I don't know if you still needed this, but I thought I might try to
help you as I have seen you help so many others over the years.

73,
Brian

I am ordering a new xtal from ICM for a Spectrum 30watt 220Mhz xmtr
(standard SCT110 design but in a S7R Spector rptr)

ICM came back with a 28MHz xtal freq!!!! and the model they quoted was a
2830B???? Nope,  not what I need.

Anyone out there have the ICM part # for a Spectrum 220 xmtr xtal OR the
load/divisor specs?? I have misplaced my entire Spectrum folder which had
all that!

Thanks!
