Re: Elecraft Digest, Vol 14, Issue 10 -- Dummy Loads

I have never understood  “the thinking” with many Ham’s when the  discussion
of Dummy Loads comes up. Some Ham’s will tell you, the minute they  hear you
tune up on a frequency that you just made a QRL inquiry on, “GET A  DUMMY
LOAD, WHAT ARE YOU TUNING UP ON THE AIR FOR”! Well, what if my antenna  represents
several hundred Ohms on one wavelength, and only several Ohms on  another?
 
I have a Bird Model 43 Wattmeter, and a Bird Dummy Load. From a “DC”  
perspective, it measures 50.0 Ohms. From and “AC” stand point it also measures  
50.0 Ohms from 1.8 MHz to 902 MHz. It has very little error even at 1300 MHz.  
That is a good thing, because I depend upon it for real work, like assessing  
line losses etc!

Folks;

The KRC2 Version 1.3 updaters have now been posted to the Elecraft  
Manuals and Downloads web site. This is a bug fix update. It corrects  
a rather nasty problem with BCD band output that shows up on the  
KRC2ACC, and may also occur on the standard KRC2 product. We  
recommend that all KRC2 owners update to this latest version of  
firmware. Note that if you have purchased a KRC2 within the last two  
months (including at Dayton), you most likely already have the V1.3  
firmware in your KRC2.

The Manuals and Downloads page also contains a downloader for Windows  
to make installation of the update much easier. If you are using a  
non-Windows system, there is a relatively easy download procedure  
using a terminal program to apply the update. (Just ask!)
