[CQ-Contest] wtb, quick rx checker

[Robert Chudek - K0RC]

This isn't necessarily inexpensive, but it's a nice tool for antenna 
analysis. I have one. The AEA VIA-HF Analyst generates a low RF signal from 
100 KHz to 54 Mhz. It'll sweep a range or sit on a frequency you enter via 
the keyboard.

There's several things I like about it. The graphic display is one. Another 
is being able to sweep an antenna at it's terminals on the top of the tower 
and bring the VIA down to the shack to load the data into your computer for 
review. You can make an antenna change and then compare the before/after 
graphs. No guessing about "what changed".

My only negative is that it eats batteries if you don't turn it off (8 
AA's), although NiMH's help in this department. And like all analyzers, if 
there's a nearby high-power RF field, the analyzer can be useless (Field 
Day, 50-KW broadcaster down the block, etc.).

The VIA-HF product is in the lower left corner:
