I have a UHF Saber 2 model# H44QXJ7139CN. Does anyone know what the TX power values should be? According to the RSS the power is currently set as follows: high is 4c, med is 4c, low is 1b and special power is 4c. What I am looking to do is set High for 4 watts or 5 if possible, Med to 2.5 or 2 watts, Low to 1 watt and Special Power to 0.5 watts. Can anyone tell me the appropriate values for these power levels? I would just do it on a watt meter but I don't have a Motorola brand cable with the watt meter plug nor do I have the meter. Thanks.

No wattmeter equals no exact power setting.
Set the thing at appropriate points on the power
scale in the tuning section, like 1/4, 1/2, 7/8, etc.
A 7/8 setting on a UHF Saber should get you about
3.5 to 4 watts output.

I usually set my UHF for about 57 for high and 4c for low Just dont Jack it all the way up its a sure way to burn up the PA

Thanks. Do you know what 57 and 4c translate into in terms of watts?

You fail to understand the concept of trimpots (softpots, in this case). Every Saber PA is a bit different, due to variations in the components on the board. A "5C" for one radio might be 6 watts... and 4 watts for another radio... and 7.5 for another. Furthermore, even within the same radio, there may not be a linear correlation - if "10" is 1 watt, "20" is 2 watts, "50" might be 8.5 watts.

Sabers are somewhat dangerous - the PA is easily capable of 10 watts, but you'll cook it in a hurry at such output.

You need the proper service equipment to align your specific radio... service monitor, proper test cable, etc. I'd suggest you either purchase such equipment or find someone who can align the radio for you.

A Saber PA, if running wide open, can put out more than 7 watts. But it won't do that for long, so be sure to trim it back. My Systems Sabers are trimmed to a meter 4.5W.

if you do alot of "ham" talking, cutting them back to around 3 watts is desirable, as that's all the little metal frame which serves as a heat sink can safely handle. The difference between 3 and 5 is not that great in terms of db. and it saves your PA life as well as longer talk time. Being that new PA's if you can get them would cost more than what these good old bricks are worth, it might be a prudent thing to do.

and a properly aligned analog Saber is one of the best synthesized portables Motorola ever made.
