Hello.
I am writing to say thank-you for guiding me in the right direction for the
repair to my K3-100.
I bought the radio from a good friend of mine, he had built the rig as kit
form. I bought it home and let it stand for 24 hours before even powering it
up. When it came time to turn the K3

Any chance you can advise those that wield a screwdriver and/or
soldering iron from time to time on their Elecraft rigs or on those of
others what the problem was? Error in build/construction, board failure
or something else entirely?

You said you can adjust the ALC and CMP levels, but you did not tell us
the level you adjusted them to.
The proper way to adjust is to set the compression at zero to start,
then increase the mic gain until you see 5 to 7 bars on the ALC meter

Hi Jay !
I suggest that you need to use ... borrow? ... some sort of an antenna
analyzer such as an MFJ-259B and find the points on each band where
the antenna -is- resonant. The resonant points on some bands will be
quite narrow (80M), but I'd think you can adjust the lengths of the dipoles

I'm assuming the cost will be about
I don't have, nor have seen, the KX3. But from what I read it looks
more like competition for the K2. In the basic 10W version (ie without

camping trips etc. A KX3 will take up a lot less space in your hand

A tuff question.
First, what are you going to so with the radio?
Second, the cost will most definately NOT be the same.
The K3 as a full featured contest radio capable of suporting multi

The only place I see the KX3 having an advantage is where size is an

Hi David,
No need to stress about CW contacts -- just realise that the only critical

Good work! Keep at it. The decoding program may give you some extra confidence,

practice. However I'd recommend to ditch it as soon as you can, since it is

That is the correct procedure.
If it happens again, your tx gain calibration may be getting messed up.

So...If I were to tweak the power supply voltage should I use the K3
internal voltmeter or an external one? If an external one, I assume
connected at the DC input to the K3 to compensate for any voltage drop.
Also, should I set the voltage under load/while transmitting? I guess
that would
Set it under TX full power load at the K3 APP terminals, measured
using an external voltmeter known to be accurate. Just probe into the
APP backshells with the DVM probes.
I use 14.2 at full load. RX voltage is then 14.5V. This provides
some margin for the power supply going bat$#!+. The

I use two 100 amp supplies here that are made by Walt Williams W5YUO They are
quiet and bullet proof, but if you want one you will have to come to Texas, as
he only sells local and only makes them on order.
They are very heavy, so shipping would be a problem...

Dear Group,
I am considering a suitable power supply for the K3/100.
One manufacturer whose supplies are readily available on our Australian
market and well documented is XP Power. These supplies are manufactured in
China but judging by their datasheets, they seem much better quality than
those
Another interesting power supply -

Hi Shane,
Have a look at these supplies:

There is an excellent review of the Samplex SEC 1235M by AD5X at
http://www.ad5x.com/images/Presentations/SEC1235M%20Review.pdf. He is
right on target with everything including the need for a simple mod to
quiet the on-demand internal fan. These cost US$140 at US retail, or
about US$120

1. The LCL300PS12 can provide 25A and has an adjustable output range of

If you operate SSB at full power, I'd recommend at least 13.8V and
preferably higher. The K3 is

I use the PowerWerX 13.8vdc/230VAC ( I have two of them) and no issues at
all.
They have a terminal at the rear as well as 2 each Anderson plugs on the
front.

I use a Diamond GSV-3000.
I have had two Samlex 1223 power supplies die in the past couple of years.
First one was replaced under warranty, but they took over 3 weeks to get it to
me. The replacement unit died soon after it's warranty ran out. That was enough
for me.
I recently purchased a Powerwerks supply. It is
