Hi.

Does any body know the (exact) difference between an NUE7231C rf-board (MTS2000) and
NUE7230C (GP1200)? I thought all MT/MTS/GP1200 boards within the same bandsplit/power are exactly the same. I replaced the defective MTS-board with the one taken out of an GP1200 and after retuning it works perfect (full specs). My JEDI-service-manual knows only the NUE7231C board. Has anyboady some infos about NUE7230C?? Maybe two different modelnumbers for the same thing???

Regards

Yes most Jedi RF boards are the same, just different numbers.
Look in the front pages of last years Price book and under exchange boards for a listing showing part numbers.

Glad that your swap worked out, good to know, got a few bad ones here too.

I find the NUE7231C for the R1, 403 to 470 and NUE7232C for R2 450 to 512 used on HT1000, JT1000 , MT2000, and MTS2000

You know Motorola, one different component can make the entire board a different number. I've swapped many an RF board between MTX8000/HT1000/Visar radios. All worked just fine after tuning (and changing the RF connector on the Visar boards).

The new board is working perfect and i have encountered no problems, even the radio is in heavy use.

Only with the old tuning-values the TX-power level was very much higher (7.2W instead of 3W!!!) after replacing (prior realignment). RX needed only a slight retuning.

Just for everyone's info, or maybe you guys know this already.

In each range of the Jedi RF board, there is a 2ppm and a 5ppm board, and each have their own separate part number.
