As Jim pointed out... the problem(s) you report are frequent for the
way Spectrum does business. The trick is to see if they charged your
credit card or cashed a check for the order.
You might need to reverse the charge before the credit card time
limit is up. IE do it fast...

Well, you kind of messed it up. Tuning the pass band for best received
signal is ok but any time you move the pass band even a small amount you
mess up the notches big time. Then when you tuned for minimum noise with the
repeater transmitter on you probably moved the notches for best noise

Remember, the narrower the bandwidth on something the more sensitivty
it can get. Theoretical sensitivty is -174dB, problem is that is at
1Hz of bandwidth.
I would recommend slowing the sweep rate, narrowing the IF filter and
taking smaller sweeps at a time. a 100kHz sweep with 10kHz per
division
As was previously posted, you need to slow down the
sweep speed and/or narrow the resolution or video
bandwidth, which may automatically slow down the sweep
speed. The filtering is done digitally in most modern
SAs, and this takes time, so the sweep is slowed down
to accomodate this. You don't

Sounds more and more like the duplexer is not tuned as well as you
were led to believe. Use two 2m ham rigs, one as a rx and one as a

Great... you've got questions..?
A spectrum analyzer is a receiver.. It gets tuned by an electronic sweep
signal rather than by using a knob. The spectrum analyzer gets tuned from
one part of the band to another part of the band (called sweep width) just
the same as you would manually tune your receiver from say frequency A to B.
I have several Vocom amps in service, Cresend backs them up 100%, their service
and response is nothing less than fantastic. never had an issue with them.
