Yes, that is 'normal'. The silkscreen indicates the position of the
capacitor, not the size or shape.

On the KPA100 kit, C2A and C6D are 1200PF 500V caps. The ones I got
were marked 122J and are of the brown type (like 103, 104, etc.) but
Hi Dennis,
Don't lose hope. You will be a better builder after you fix this. If you
don't have one, get a digital volt meter. You can probably get a decent one
for about $20. ALWAYS check the voltage , and the POLARITY, if DC of any
power supply, including batteries before you hook them up to

I did that too (worked Sierra Hotel One Tango) with a ETO/Alpha 91B, some years
ago. Boy, did I say some sharp words!
Alpha support got me back on line, just a couple of fried diodes on the control
board. With the K2's minutarisation, some extra ICs might be gone, but it can

Once again I want to thank you for your help in repairing my Elecraft.
I followed your instructions and quickly discovered that pin 8 on the DB9 of the
KIO2 was not soldered. Pressure alone had held it in place and it sure looked
solid, but with magnification I saw it was not the same

And this will only get more confusing before it gets better.
There are actually two references of RP3 on page 3 of the Parts list.
The first is line 1, as you have found. The second one is on line 18
(or line 4 under the heading Components on Front Panel Board). There
is where you'll find

Thanks to all you folks for the recognition, it means a lot. It is a joy
working with you here on the Elecraft reflector.
Believe it or not, I really enjoy solving puzzles, and that is what I think
troubleshooting is all about - it is a puzzle to be solved.

I don't post on the list often but I do check it several times daily and
especially watch for Don's posts. They are ALWAYS useful and I have learned
a great deal from them. It is wonderful to have his experience in trouble
shooting and general electronic knowledge. My thanks to him.
Todd,
This is the kind of attitude that expresses the very best of the spirit
of ham radio. Building and then operating a K2 is a truly rewarding
activity. Being a member of a world-wide community that provides a
endless supply of support, encourage and recognition provides the lesser

Hi gang,
Where can I buy a good quality LINEAR power supply that will provide at
least 500mA (that's all I need) at 12-14VDC? I don't want a switching power
supply, due to fear that it would produce HF crud.
Thanks very much 73,

good eve, not perfectly clear on which is the Flat side of c9, on the board
for auto tuner for my K1. The outline on the board is completely rounded, not
much help. Both sides of c9 are flat, one side has more surface area then the
ofher side. Which is the flat side?
I've nearly completed my K1, and the receiver has been calibrated and
works extremely well. While calibrating the receiver against my K2, I
had a 3 foot antenna consisting of daisy-chained alligator clips
attached to the antenna jack, and I was picking up not only the adjacent
K2, but also
Tom,
You have one of the new boards where the silkscreening did not adhere over
the tinned solder pads.
Rathr than trying to describe how to mount the capacitor in words, look at
the parts placement diagram in the back of the manual for a picture.

Hi, sorry if this repeats previous information request, but I did a lot of
searching and didn't find anything directly on point (even though there were
several threads on preamps and Heils, etc.)
I downloaded the Microphone Pre-Amp for Heil schematic on the Elecraft
website.
My
Radio Shack used to sell a small 1A linear supply in a metal chassis.
Wall mount supplies are linear if they're heavy, but usually not regulated. 12VDC at 1A is a pretty
common size.

Sadly, the transmitter has not been so kind. Any attempt to put the

I recently bought a Heil 'Handi-MIc' with the Icom element (designated

Definitions first - RF IN and RF OUT are designation of the RF Bandpass
filter only - on transmmit the signal goes in as RF IN and comes out as RF
OUT - however, on receive the path through the RF Bandpass is reversed, so
'in' is 'out' and and 'out' is 'in' G.
Since you have a scope, I
The Heil microphone preamps are required for the Heil microphones using the
HC4 and HC5 elements. The electret elements do not need a preamp (but they
do need a resistor at the mic jack). The Heil mics designated for use with
Icom transceivers are usually of the electret typw and work quite well
