[Wbo2] Using the Bosch WB sensor with L1H1 circuit board

[bcroe at juno.com]

Building a commercial unit to a very small market can be a  
costly thing.  Some of the features, and most of the overhead 
of a commercial unit are not too useful to the occasional user.  

It is not so hard (in some cases) to build a basic no frills 
unit which may actually better serve the amateur tuner.  I 
would rather have the unit I built (for my purposes), than 
any more expensive unit available.  

Check out the specs, don't pay for what you don't need 
(including a huge overhead).  Accuracy to extra decimal places 
is useless to the amatuer, but a good dynamic display is 
everything.
