A few times over the last few years, a friend's UHF MSF 5000 has been
found to be off-frequency by 5 KHz on receive.
We find this out, of course, because everyone sounds bad, and then one
day we thought... hmm, that sounds 5 KHz off frequency...
Repeater is on 449.625 TX, 444.625 RX.
VERY interesting and I don't think it's off topic at all but I am not the

I would go with the .80/40 since both duplexers will be rejecting both
TXs nearly to the maximum. I would keep the UHF close for the same reasons.

I'd go with 50 to 100 kHz spacing from the analog channel and use

The problem is on the user end, if there's only 10 Khz between both

You're in luck! Both Saber Vehicular Adapter manuals are still available
from Motorola Parts:
6881058C70, and 6881061C60, each about $5- less than the cost to make a
