[Elecraft] RSGB RadCom K3 review posted on RSGB Members web page

Hmmmm!  Makes me feel like I knew something when I decided to get the 400 hz 
filter instead of the 500 hz filter!

As far as power settings, I usually like to follow a self imposed rule of 
never running a transceiver at more than 85% of "maximum".  It probably is 
meaningless in many cases as far as really being a safety valve, but I 
figure that less than maximum strain ought to have some beneficial effect on 
the finals, etc.  It probably sounds very arbitrary, but I follow this same 
rule in lots of things--even other than ham radio.   In golf, for instance, 
I find that swinging the club at about 80-85% of what might be my maximum 
results in better contact and consistency.  As far as the receiving station 
is concerned, 80 or 85 watts vs. 100 watts should be imperceptible. 
Although the K3 may not be one of them, there are lots of rigs out there 
that are very closely spec'd, either as to the finals, or the filters, etc. 
Some rigs have lots of  "cushion"--the older TS-50 comes to mind, which 
apparently could easily  run 200 watts or more with the finals in that rig. 
Some folks were actually cranking them up to that or higher!  But nobody 
seemed to be too concerned about what the bandpass filters could handle, 
etc.,  and that bothered me enough to resist the temptation.  So, I usually 
set my K3 at around 85 watts if I'm running QRO.  Ignorance is bliss 
sometimes!

Interesting review.

Considering IMDDR3 it seems like one should stay
way from the 500 Hz filter, looks like the 400 Hz
is the filter to get.

Also the TX probably shouldn´t be cranked up to
120W but instead 100W should be maximum.
