Hi Richard,

It's a  PC controlled  (USB)  swr/watt meter.    Coax sensors connect to 
the main unit which connects to the pc.     First off, if I were 
starting from scratch today, I would look  at some combonation of the 
Elecraft meter or Power Master in conjunction with the Hampod.  I've 
never used either one, but  they are options - maybe better, maybe not.

  Good things about the WN-2:
Audio readout of power  and SWR, either by it's internal voice with a 
key press, or with your screen reader.

Can be set up to disconnect an amp keying line in the event of  high 
swr.   Kind of a moot point for me, since the MFJ-998  has a similar 
feature.

Many options of sensors available  for different frequency coverage and 
power levels, from  QRP to mega QRO.

Bad points:
Software is graphical and  not blind friendly.  However once set up, 
either by trial and error or with sighted help,  things aren't so bad. 
   There are many graphs and charts and visual meters that are lost on us.
.

The tones for tuning an amp or tuner are sort of an afterthought and 
are worthless.   This is why I keep my TW-1 inline, for the audio tones. 
   The tones in the WN-2 react too slowly for practical use.   A sighted 
ham  could watch a pie chart on the screen change color as   power or 
swr changes, but the tones don't react fast enough for tuning an amp or 
tuner.

You can download the software at wavenode.com and  see how graphical it is.

There is a review from a blind perspective  at hamradioandvision.com

I've been using this for a number of years and am happy with what I 
have.  I had the original WN-1 LPT port version years before the TW-1 
came out.  however science marches on and there may be something  better 
suited today.   None of this stuff is cheap, so  do moocho research 
before  spending any money.

73, Steve KW3A
