Hi All,
I have discovered a problem today that has me a little puzzled. I use
my K2 primarily transverting to 6m with a homebrew transverter from 28
MHz. I decided to have a play with Julian G4ILO's K2net software to
remotely control the K2 over the wireless network in the house. After

Oops! I have found my problem. It seems my failing memory had the KIO2
output as switching the amp directly. This is not the case, it switches
the transverter to tx mode which then switches the amp. It is now
obvious why the transverter fails to transmit when I disconnect the KIO2
lines!
Operated Field Day as 1B (5w and battery power) into a 120 foot
end fed wire launched out and over a 45' pine tree.
The rig was a Elecraft K1 w/autotuner at 5W, with gel cell battery power.
I laid out two radials for each band. In 4 1/2 hours I managed

I picked up K2/100 #4760 on eBay a few weeks before field day - it was

several times and got the receiver working well.

Not sure I understand your question. Obviously, everything wasn't found at

For me, the most important part of doing inventory is identifying all
the components, especially the tricky capacitors - like the ones
labelled 270 and 271. It's pretty darn easy to use the 270 for a
270 pf capacitor and then later on complain that the 27 pf capacitor is
nowhere to be found.

I've been reading the technical literature lately and have been following
an interesting development: ultracapacitors. These components are on the
order of 5K to 20K Farads. So I did a little calculating.

1 Coulomb = 1 Ampere Second
Thus 1F = 1V * 1 Amp Second.

Hi Kevin,
One day we may be running our rigs from ultracapacitors instead of
batteries. They recharge extremely rapidly. They store charge for a
long period of time. And they discharge at rates that put the best
batteries to shame. If you need high amperage devices (think your 100

Mike,
I agree -- well almost.
The K2 is packaged into several bags - the front panel, the control board,
the RF Board (2 packages) and a hardware bag.
While there is some mixing from the hardware bag items, the electronic
assembly moves smoothly from the Control Board (1 bag) to the Front Panel
The articles I've been reading put these components in association with
solar cells, regenerative braking, and with various types of fuel cells as
the electricity source. Fuel cells and ultracapacitors play very well
together. The economy of scale is coming from the hybrid automotive
market.
