[Elecraft] K2 sn4011 is on the air !!!

[K8RA@aol.com]

I completed K2 sn4011 this weekend and it worked perfectly.  I installed the 
SSB, NB, 160 and tuner modules and each one checked out exactly as perscribed 
in the manuals.  It sounds great on the air and the receiver is very quiet and 
sensitive.  It puts out about 15 watts as designed on all bands.

I do have one tip.  I first tried to peak the receiver as described in the 
manual using the background noise with the pre-amp on.  It worked but tended to 
result in a broad peak.  So I hooked up my Wavetek signal generator to the 
antenna input and measured the output with a good audio voltmeter at the 
headphone jack.  It made a world of difference in aligning the radio.  the peaks were 
very distinct and sharp.  I have no doubt that the final results are 
optimized.  I know that everyone does not have a good signal generator and Booton AC 
voltmeter laying around, but I recommend finding a friend who does and spending 
an hour at their workbench doing the tuned circuit alignments in the radio.

Tonight, I begin wiring the DSP unit.
