Are 1MEG boards (spectra or saber) absouletly required to use basic secure functions, or will they operate with 512k board?

I picked up a UCM (3.52 I think) from a board memeber. Initally I will just getting key fails (can't find my KVL cable to load a key). Then yesterday, I was getting 9/10's and 1/90's with a 512k spectra.

the UCM version is tied to firmware as to whether or not it will work.


if memory serves, only ucm 2.xx and lower modules will function below host 5/6....


methinks your module is "too new"

In the pre '98 512K radios I've worked with the EMC has been typically 0.60 or 1.00, non UCM, and generally single algorithm.

Hmm.. akardam also sent me a SRN about the same problem that I am having, but I suspect the vocon issue more than anything.

Doug, this is one of those Dayton Specials that you suckered me into :) The firmware was bumped up to the most recent about a year or two ago, so I suspect its just being 512. I should know more later tonight. Just may have to swap vocons for this radio.
