Hello Tom,
I ran my K2 last weekend on a battery (from my backyard â fully
charged 52 Ah. Gel cell), and everyone on the net (40 meter SSB)
complained that the signal was distorted and just plain sounded very
bad. One person suggested that it was the 12 volts put out by the
battery,
Hi Tom, the K2 works very well from a 12v supply in normal
circumstances; indeed, it is designed to run from an internal 12v supply
as an option.
There are two possibilities that spring to mind from your description of
the problem:
1. You may be using a long power cable that is too light
Thomas,
I exclusively run my K2 with battery power (oh, I think I've used an
Astron RS-20M on it once). I haven't had the problems you are
experiencing just because it was run on a battery. Many times from out
in the field I use smaller 7 AH gelcells (well, they are smaller than
what I
1. You may be using a long power cable that is too light duty for the
task and therefore causing a volt drop at the K2.
2. There is RF getting into the power line and causing the distortion
you experienced.
Thanks for the replies. I am using #12 wire, with Anderson powerpole
connectors.
Why don't you measure the voltage drop with a volt meter and let us know
what it is? A 52-AH battery should be sufficient to run a 100 watt rig but
as batteries age their internal resistance increases with the effect seen as
a higher drop in terminal voltage under load. There could also be a weak
John,
Those two capacitors would cause you to have trouble getting a signal
through the bandpass on 80 and on 40 meters.
Yes, 56pf is labeled 560 and 560pf is labeled 561 - 82pf is labeled 820
while 820pf is labeled 821.
Since you installed the incorrect capacitors in C12 and C4, the further
Greetings,
Since completing my K2 in 2002, I've been working on a
long term, back burner project to design and implement
a nixie tube clock around a Motorola/Freescale HC908.
When I finished the clock, I had two unused pins on
the HC908 that could be used as a serial interface. I
also had room
Any magnetic fields nearby? A standby charger on the GelCell perhaps?

the #12 cable should be just fine for the K2/100, BUT the battery may be

at higher power, that battery should allow you operation for about 2 hours
if it is in top condition. The condition of the battery may have a

Don,
I checked U6.
pin 7 is okay - 5 V
pin 8 is strange - 5V always (receive and transmit)
I could not find a bridge somewhere on my board causing the 5V on pin 8.
It looks like output of my Firmware chip is defect.
This means I have to replace in my K2 Firmware chip and U6 :-(
Maybe you can

For a number of years I used the Bencher paddles and was happy. Then I
got wind that there was something better. I picked up a used pair of
Kent paddles and guess what, they are definitely better than the
Benchers. Benchers have a squishy / flexible feel, Kent is solid.

Also worth consideration is the Bencher Hex key available from Elecraft.
I have the Bencher BY-1 and the Kent TP-1, both good keys but the Hex key
is much smoother. (IMHO)

Unfortunately, a quick trial at Dayton is not adequate to determine

I'll add a fourth vote for the Begali paddles, to Joe's three votes :)
But note: the Begali simplex (dual) paddle costs less ($138) than the Hex

Begali simplex mono (single lever paddle) at $165. Of course, you can pay

The problem could well be the age of your battery and its aging rise in
internal impedance. If it will not charge to 13 plus volts of a fully
charged battery, it indicates excessive internal resistance/ age.
The fact everything cleared up on an AC to DC supply supports the battery as

Keith,
I would say yes. The Kent has a mechanical feel and sound to it (which
isn't necessarily bad).
The Hex key is much quieter and smoother in operation. The Hex key of
course uses magnets
which gives it a totally different feel.
The flex on the arms is not a factor if you don't slap it

Yes, one side of C4 is grounded (see the schematic). With 40 meters
selected, check the resistance to ground on both C4 leads - if you find
ground on both leads, look for the solder bridge. If you have higher than
zero ohms on one lead, all is well. Note that if you do not select 40

I am having a problem with my T1. It was working fine, now it tunes to
variable SWR (typically around 3:1),
after I possibly?? put in too high a power for a tune. The indicator
shows a tune, however 2 other meters tried show this to be incorrect
