[HBQRP] QRP watt meter ???

[Arnie Grubbs]

Hi Guys,

Quick question for some of you hard core QRP'ers...

I have an oak hills research QRP watt meter that I got from E-buy a few weeks ago.
It is a model WM-1.  I was going to purchase the kit and build the WM-2 but couldn't
pass up the deal on the auction site.  

BTW, I think that this might be a very good HB-QRP group project some time, even
thought they want about $100 for the kit.

On the OHR website, I see they have the WM-2 on the website at

with better pictures at..

My ??? is, what is the difference between the WM-1 and WM-2?  
The only thing I see from the WM-2 pictures is that it seems to be able to be powered from
an external Vdc source in addition to the internal battery.. is that the only "functional"
difference?


Thanks.. Arnie - KA0NCR
