Rick, and Bob, Thanks for the reviews. I note that Rick started his off with
a clever limerick. Here's another limerick in honor of both reviews: The K4 has
been a long wait,
There's been lots of talk and debate.
But its finally here,
And the verdict is clear;
Reviewers say:"It's really
I had a similar problem with our K3/Astron PS atP40L-P49Y. Removing the power
cable from the back of the Astron and sanding the wires ends lightly (though no
corrosion could be seen) solved the problem.

This is certainly getting way off topic on the Elecraft reflector, but I can’t
resist mentioning that I have visited the FAST telescope in Guizhou Province.
Here is a brief explanation from my trip notes (we were guests because my wife
is an astronomer with many Chinese colleagues). It’s odd
For one data point, when I got up for other reasons this morning at 2:20
a.m., I turned on the radio, as I need KH1 on 160. They were very solid
copy on 1822.5, and easy to work, using my K3 and KPA500, with only an
inverted vee for TX and RX. I was surprised that they were solid copy, as
DX Engineering sells several also.

You might want to try an industrial supply
Eric,
Hallelujah! First acknowledgment of such a possibility! I vote to put a
second amp module in the RF Deck (i.e., an RF deck that is the same as the
total size of the KPA500) and have a separate switching supply in another
box. 1200-1300 watts would be a sweet spot if 1.5K is a problem.
I thought I would share a fix to my KPA-500 with the group in case someone
else might have the same problem.
I have an old amp (two-digit serial number), and it has performed flawlessly
until yesterday. Suddenly the Operate-Standby button stopped working, and
then I noticed that other buttons
Ian,
At P49Y, I also like to use SLP=0 for pileups, because then one can "ride"
the RF Gain control to try to differentiate signals within a pileup. On the
other hand, for casual operation, it is easier on your ears to use higher
values of SLP in order to make the volume of signals more
