I need to take my K3 to class. I'll need just enough oomph to talk to the
serial
port. What would be the minimum rating for a PS? Any suggestions for a small
packable
one?
Would a couple of layers of bubble wrap be sufficient for packing the rig in
checked
buggage?

My K3 with two receivers draws about 2 amps on receive. It drew a bit over 1
amp before I installed the second receiver. For tr

Rose Kopp made one for me that fits this description -- in fact, she
made two, the second for my running buddy, N3ZZ, and they're configured
to lash to

Rose does custom things. The bags she made for us were custom, but the
link together was something she had done for W0YK, and the pouches for
computer and PSU she had done for someone else. .Rose is quite
responsive via em
Thanks Jim. I'll check Rose's site.

Looks like a Radio Shack 22-507 PS will meet my needs @ 3A. Unless someone has
a
better/cheaper solution. I have 4 20 amp (or better supplies), and don't need
another
of those . .

Current rating isn't the only spec for a power supply -- RF noise is a
VER
Understood. The point is that I ONLY want to talk to the RS-232 interface. No
xmit or
recv is needed. I'll be in a Mac programming seminar at Big Nerd Ranch. Really.
I have one of those RS supplies in the shack, powering 4 receivers that listen
for
railroad traffic and send it to an aggregator
Take a look at the TDK Lambda switch mode power supplies. The LS50-15 that
I have is pretty quiet, with output voltage adjustable from 13.5v to 16.5v,
about $20 from Newark Electronics. The LS35-12 is a bit cheaper if you
really only need 12 volts.

Thanks, Chip -
Looks like just what the doc ordered.
