My KX-1 do crazy things...

[SV1COX-2]

Operating my KX-1 for 8 months now I was more happy I could ever dream.

 

Since I put the KXPD1 key on it and start to do crazy things:

 

1. Some times I have output power some no or less power.
2. It start to tune while I transmitting

 

 I figure out that maybe it is something with my body effect (now with that
key I have to hand the KX1).

 

Any ideas? Hints? Suggestions?

P.S. Antenna is Buddistick

Ge Panos,
It looks as a bad solder joint and/or a mecanical effect on the PCB induced
through the key. Give a look at all solder joints and all mecanical
connections and or effects.

Panos,
Can you create the same conditions when driving a dummy load?
If it happens only when using an antenna, then yes, your body may be
acting as part of the antenna system and can cause strange behavior.

I had the same problem as Panos when I was trying to operate K6DGW/MM
with my KX1 from a cruise ship balcony on a Panama Canal trip in 2005.
There wasn't much room for my wire antenna and it was obvious I was part
of it ... likely the dummy part of the load :-)  I had the counterpoise
grounded to the ship, but it was about 2.75 meters long.  I discovered
that if I grounded the radio itself directly to the ship [fortunately, I
had a couple of short clip leads with me and I managed to get the teeth
of one through the paint on the rail [there is a LOT of white paint on
ships], the problem went away.  www.foothill.net/~andreaj/Ham43.htm

Many thanks to all....

i wait till i install the 30m board to make some new tests and answer here.

yes deffinitely was due improper antenna. Part RF feedback in KX1 and part my body as ground.

KX1 still rocks here :) now on 30m too :)

many thanks again, have fun
