It may also be worth looking at this from the other end. Presumably
Elecraft's bags are 'hand filled' rather than by machine, so there is
the possibility of error there. Changing a long established method of
grouping all of these components, possibly for something more complex,
may introduce

Participated a couple of hours in a 9A operation at N4N (amazingly
organized) and then had a little personal FD of my own with a recently
acquired K1 thanks to John (WL7M) - was KL0WN - yes, he worked as a clown
with RB BB Circus - and is a very accomplished builder! Excellent job
John - tnx
Surely some out there have read Philip Jose Farmer's River World series.
Mark Twain ran his Fabulous Riverboat from an ultracapacitor.
Can you imagine what would happen if you accidently shorted a ring across a
fully charged ultracap of 20,000 Farads? Goodbye finger(s).

Hi,
I'm not sure if anyone else has noticed this but the time for my K2 to switch
from transmit back to receive in the SSB mode seems a bit lengthy. It's
probably in the 200-400 mS range which is annoying. Am I missing a menu
controlled item or is something wrong?
Any insight would be
Kevin,
The first thing that jumps out at me is that
capacitors voltage drops at what I remember is a log
rate when discharging. A capacitor would still have
something like half the coulombs of electrons left
inside when the voltage would have dropped too low for
the average rig to work
Hallo Mike,
The only parameter I now is the tr-Delay Parameter in the Menue, but it just
should affect CW mode. I do not have any
Longer delay.

Mike,
Is it possible that you have the K2 set for VOX operation ('L' or 'U'
indicator blinking)? - if so, the VOX delay will increase the time for
switching back to receive. The PTT switch will still activate the transmit
condition even though VOX is selected. Press the TEST/VOX button until
And I will add that we should be very cautious around batteries and battery
sourced power supplies too. Batteries will produce a LOT of current if
shorted. I once tested an 8 cell pack of AA sized NiCad batteries in a lab
for their short circuit discharge current - yes the current dropped off
with the KXAT1 installed, what does this feature actual do to make receive
better.

Since you don't know which one to really trust, may I suggest that you
connect an RF Probe directly across the dummy load (a TEE adapter at the
dummy load connector makes a convenient way to attach the probe)
It seems to me that the calculations in the original post are not quite right.
1F = 1V * 1 Coulomb.
The Farad is a Coulomb per Volt or Q/V not Q * V
This starting point inserts errors in the calculations that follow.
For example:
Thus 1F = 1V * 1 Amp Second.
The unit V * Amp * sec is
Hi Michael:
In case you don't have an antenna analyzer and the OHR dummy load you refer
to is their 100 Watt RF Load, I just measured the impedance of my OHR
dummy load with my MFJ Analyzer. It shows 50 ohms resistive and no reactive
component at all until the freq gets up to about 16 mHz. So I

First of all thanks to everyone that responded to my query abt. fiberglass

With the help from you all I was able to make a choice.
My decission went in favor of the heavy duty spider pole 12 meter high.
Low weight and short transport lenght was main reasons.

Hi Don,
Thanks for your reply. First the easy answers:

I noticed this at Field Day. The club was using a repeater with output
on 146.625. As soon as I turned on the K2 we got hash on that
frequency.
Any suggestions for tracking this down?
You must have an older KIO2 with the 16.289 MHz oscillator. The 9th
harmonic is 146.60 MHz.
You can change
Sam,
Funny you should mention that. In my shack, I have the K2 with a KIO2
and also a 2 meter rig nearby. Whenever the K2 is on, the 2 meter rig
stops scanning and hangs on 146.625 and just breaks the squelch. As soon
as I shut the K2, scanning resumes.
