Hi Guys,
Has anyone ordered a cover from Ernesto in Puerto Rico? How did it work
out? I ordered my Hex Key cover from him by postal money order (his only
accepted form of payment) in MAY. Despite numerous cordial emails from him
advising that the cover was completed and promising a

After some more debugging it appears that the ksb2 is causing the
problem.
Removing it returns tx power to normal levels. Some might say, good

don't need ssb anyway.
Sounds somehow familiar. Check the resistor packs.

I hate to admit this, but I finally finished the KX1 I
purchased over a year and a half ago. I made good progress
in the beginning, then ran into a snag, so I decided to set
it aside for a while. That while turned out to be over a year.
At any rate, #577 is now live and on the air. Power
Hi Pat,
There are three two signals fed into the KSB2 that directly affect
power output. One is V RFDET which controls the base of Q1 and the
other is ALC which is applied to the collector of Q1. Since removing
Q1 makes no difference, V RFDET isn't likely the cause. But the ALC

I bought an used linear amp Ameritron AL-811H for half of the price

If I want to connect my KPA100 to an Ameriton AL-811H, what should I
do ?
It seems that Relay control conector behind

The MD2 from Elecraft is wired the same as the Proset-K2, no
adjustment necessary when switching between them.

I fixed the problem by cutting back power to 15.0w.
Q: is this normal? Is 3.7A for Cal Cur too

It's been my experience that even with marginal conditions (when even QRO
doesn't work), as long as you have a decent antenna, 5w is plenty even on
SSB. Now if I'm ever forced to use a marginal antenna, I'll consider going
to 10w (not 15.2 - thanks for the heads up!) or maybe 100w.

Hi all,
So far I thought I was doing great. Just to save some time I thought I would
ask the collective before I go digging for misplaced components and solder
bridges.
I am building a K2 for a friend. I am at the first point of power up
testing. Control board, front panel and a few components
Hello Folks,
Another fine day today. Well except for the mountain beaver deciding
our foundation was meant for hole digging. But we will deal with him.
Means I'll not be hanging any wire antennas but hacking down the last
year's growth of alder. But the back 'yard' needs a clearcut!
Quick update. I checked the 4 MHZ oscillator and it is working. On the
control board that is. Still no joy. I also unseated, reseated all of the
socketed chips and checked for bent, misaligned pins. Socketed chips are as
they should be. Also at the suggestion of another, checked to make sure the
Front panel's U3 powers the shaft encoder, the push buttons and the
pots, makes it look guilty, but it has nothing to do with the LCD
display which also fails once every 5 power ups.
The control board seems to initialize itself properly whenever the
LCDs work, so that will be somewhere down on
18 matches
