They were using scripts, and they do have a lot of single pol gear (airgrids),
but nothing to explain why a lot of radios were locked
to MCS3 or MCS1....mostly fixed now. we've been touching every radio

We have a 2.4 network we recently acquired - in going through some of the

I've never seen a configuration like this nor have I ever heard of it being
done.
Why would someone do this? What possible benefit could this have been?
If a radio is on the verge of upshifting mod rates, but will shift back down;
causing a flutter in mod rates; this can take up air time. In such case, you
could fix the max mod rate to the lower of the two to stabilize performance;
but you wouldn't want to go to MCS1.
Maybe they did it to limit usage by limiting the bandwidth via mod rates?
That's about the worst way to do it I can think of, but it would have that
effect.
Perhaps they were configuring the radios via a script, and it's an error? I
saw that happen a couple of times when my field people restored backups on
dissimilar hardware, it caused 2x2 units to get locked to MCS7.
