K2 Problem and new elecraft kit proposal

Hello everyone here.
Last week , I posted a mail on this list , reporting a problem with my K2.
Strange behaviour , sometimes loosing all the commands on the front pannel ,
sometimes loosing RX sensitivity , and recovering it by pushing band+ and
band - , I even found the K2 in TX mod e, mode where it decided to go by
itself.
Today I opened the box , and immediatly found the problem origin :

There is a unused RS232 connector hole in the rear pannel. A mouse entered
by this hole and used the K2 as an high cost toilet. I took all the boards
off the box and started to clean them. Tomorrow I will reassemble it , and I
hope all the problems will be gone away.
So U all K2 users , U should put the connectors in the options holes to
avoid this pb.

I suggest to the Elecraft crew a new kit:

K2BUG: ultrasonic board to avoid mouses , spiders ect... :0)

I just put black tape across all the open holes from the inside. I figure it
might also help with cooling (controlling where air enters and exits).

RE: K2 Problem and new elecraft kit proposal

Oh, Dom this is priceless!! Too funny.

I could see how randomly placed natural semi-conductors could mess up a
circuit.

I wonder if anyone else has had problems with creatures getting into the
K rigs while they are in the field? I could see a backpacker having
something inside the radio when he wakes up in the morning. Probably a
good idea to seal every hole.

Re: K2 Problem and new elecraft kit proposal

I can tell you that moisture is a problem :(

last rove we spent all of Sunday driving around in pouring rain.
Unfortunately, the Jitney leaks a bit, and as the day went by more and
more water was accumulating here and there and one drip was landing
unnoticed on the low-band station K2. It started acting very weirdly
as you can imagine. We opened it up and propped it against the dash
with the A/C running + heat, and by the next stop not only was it
working much better but the overall gain seemed to increase quite a
bit!

He is a thing for people to do if there is a problem with any
electronics getting wet.

I do model war ships that are designed to sink. What we do when the
electronics get wet is,

Open the unit, "unplug and remove battery's" With a squirt bottle, douse
the circuit board with rubbing alcohol. The alcohol with displace the
water from the board. Drain the alcohol and let the remainder evaporate.
When there is no trace of alcohol moisture present, the system is safe
to use.

I have used this on many electronics systems and has worked perfect each
time with no corrosion on the board.

In reply to this post by f6dro

F6DRO: Rodent urine can be very corrosive - the combination of
rodent urine & fecal matter even more so & the former often
comes with the latter.

If not cleaned immediately - and cleaned properly - can come
back to haunt you. GL.
