[FedCom] RE: feds using nextel

[tvsjr]

<off-topic>
The irritating part of the 2660 (and apparently all of the 26xx monitors of
that vintage) is that, when tuning anything with a wide passband using the
tracking generator (think bandpass filter), these little peaks start
appearing. Moto calls them "markers" but they make tuning filters a real
chore.

The 8921 is an 8920 with all the options... enhanced tracking generator,
spectrum analyzer, ultra-high-stability OCXO, etc. The only thing it doesn't
do that I'd like is P25... but I'll find a 2975 one of these days :-)

I figured that it ias so that you could do more, and not hav eto put up
with the problems with the tracking generator.  What does this HP monitor
have on it then?
