[TenTec] OT: Rob Sherwood's impression of the FLEX 6x00

[GARY HUBER]

I agree with Bob, a SDR like a FLEX-1500, (you can buy or build for a 
Soft-Rock for less) along with a basic PowerSDR like program and a Radio 
Control Program (DXLab Commander for example) with a computer, will work as 
a station monitor, panadapter, scope, and other things.  Download Audacity, 
software for recording, editing, and analyzing audio and you have the tools 
to analyze your (or others') transmitted audio.

Other than the SDR and interconnecting cables, the cost is minimal, as the 
software mentioned above is free.

A FLEX-1500 or a FLEX-1000 if you can find one should work just fine as a
station monitor.  It will allow one to "see the band" and allow one to
observe their signal within limits of the sweep range.

Personally, I went a different direction and purchased a RIGOL DSA815-TG.
Now this cost a good bit more, less than $1500 delivered, but does a LOT
MORE in terms of being a piece of test equipment thus allowing one not only
to "see" their signal but make other analysis of their signal.  It has a
tracking generator or signal generator that is quite nice for other work as
well.   This product was reviewed in QST some months ago.  Performance wise
and feature wise it compares favorably to my $30K HP Spectrum Analyzer,
except the DSA815-TG weighs 9 lbs and the HP some 45 lbs. and it is about
1/8the the size of the HP.

Other than this, the SB-610 in good clean and working condition is worth
abut $250 or so.  I have two of those, one dedicated for the AM station and
one for the station at the house.

In any event, understanding how to use and analyze the data presented from
any piece of test equipment or station equipment is the advanced key to
success.
