Unless I missed it, the LEDs appear to be just 'light'. Had they
turned the LEDs on and off at a defined audio rate, the signal could
have been detected with a soundcard with a waterfall display giving an
increase of x10 in sensitivity.
Love the supercaps though. (vacuum tested?)

Hi Folks,
The hotel at which the AMAST-UK Colloquium is to be held will not keep our
allocation of rooms beyond 3 weeks before the event.
SO TO BE SURE OF A ROOM AT TYE HOTEL YOU SHOULD BOOK WITHIN THE NEXT WEEK
(BY 17 AUG) TO AVOID DISSAPPOINTMENT!
The dates of the Colloquium are 14 -
Below is the announcement from the National Scouting Museum here in Irving,
Texas about a contest to select Scouts to be the questioners in an upcoming
ARIAA contact currently scheduled for Jamboree on the Air, (JOTA) weekend,
October 20th. Scouts who enter should be capable of getting to Irving
I bought an Icom AG-35 preamp about a year ago. The fellow ham advertised it
as virtually brand new and it was/is. I planned to use it this summer with a
TS-2000 which doesn't supply 12v voltage to the coax to power a preamp as
other xcvrs do. I used a Mirage KP2 unit to inject power to the coax

First, make sure that nothing else that might block DC is in line between
the power inserter and the preamp. Then, have someone go up the ladder and
listen as you turn the power feed on and off. They should hear a distinct
click as the relays in the preamp engage. Tune to a distant repeater,
Hi Rick
Check the KP2RC unit output volt if it the same as the input supply volt !
This volt suppose to be same on both the input and output coax connectors
of the KP2RC control unit .
Check the RCA phone jack at KP2RC unit if there any bridge or metal twist
any short in this jack will drop the
Rick,
I suggest you use a VOM or DMM to measure the current drawn on 12 volts
going to the power injector. If everything is connected correctly It will
draw 30-200 mA. Confirm that you have continuity in your coax. Some
lightning arrestors have a DC block built in. It is best to test it with a
