[Elecraft] K3 SSB is it really better

[Maarten van Rossum]

Bjorn,

We have already exchanged emails about this but just to be sure, did you
change the TXG VCE to a lower setting?
In my case setting it to - 3 dB (minimum) made all the difference. Now even
in the first few seconds it puts out right amount of power.

Gary also told me te set the PS to 14.0 VDC because I was not able to get
full power (100 W) om 6, 10, 12 and 160 m. Changing it form 13.8 tot 14
VDC corrected that and now all is perfect except for 160. On the Top Band it
is negligible 5 W short.

As far a I can tell, my K3 is doing what it´s supposed to do. During the CQ
WW SSB this weekend I will give it a run for it´s money ;-)

73, Maarten
