[Elecraft] N8LP wattmeter kits

[Larry Phipps]

Just in time for Christmas... sort of.  For all of you who expressed 
interest in the LP-200 project, I have added "Buy Now" PayPal buttons on 
the LP-200 webpage. Deliveries will start in early January, due to 
manufacturing lead time on the PCB and bottom plate.

I made some small changes, which include adding the HP dual Schottky 
diode detector, which eliminates diode matching and some of the 
calibration procedure... and I also changed some of the cal screens, 
adding a second gain screen for high power, and an offset screen for 
zero'ing out the opamp offset error.

I have also started a new wattmeter project, the LP-300, which is a 
handheld, battery operated directional wattmeter with digital readout. 
The project is in the prototype/testing phase, and should be ready in 
2-3 weeks. It borrows heavily from the LP-100 and LP-200, has digital 
readout and a number of features important for portable use. I mention 
this only because I thought you should all know about it in case you 
feel it is better suited to your needs than the LP-200. I believe the 
three wattmeters provide different needs, but there is obviously some 
overlap of features since they are all wattmeters ;-)

I have also added a webpage with a comparison matrix of the three 
projects. If you go to my home page, www.telepostinc.com, you will find 
links in the LATEST NEWS section to the LP-200, comparison matrix and a 
preliminary look at the LP-300.
