[Elecraft] Pleased...P3 No. 1327...

[Fred Townsend]

I would disagree on being the 'most reasonable' [fix]. However I do think
the relay solution is a good one if you are planning on plugging the 12 V
coffee pot in. 

I think this issue is the classic glass half empty or half full. There are
really two issues:
1) A field Fix
2) A wish list for feature products

As for #1 the Radio Shack solution is a good but one should apply the
appropriate Murphy law that being the probability that the Radio Shack
appliance will be forgotten on any field day is directly proportional to the
distance to the nearest Radio Shack. If FD is held at RS then the appliance
will be remembered. If FD is held in the Yukon Territories the probability
the appliance will be forgotten is 99.9%. Ask any FD chairman!

As for #2 yes it will require a change to the PCB, the sheet metal, two
manuals, BOM, and possibly the fuse rating. I still think it's easy to do.
To do being on the next clean up run of the PCB. Easy does not mean
insignificant.

  The current available from the K3 DC output jack is limited.  A PR6 and a
P3 just about max it out.
For those who want to turn multiple 12 volt powered accessories on and off
with the K3, drive the coil of a 12 volt relay from the K3 DC output jack
and run the power supply feed through the relay contacts.  Lots of devices
can then be turned on/off with the K3.  That is the most sensible solution
IMHO, no worry about overloading the K3 12 volt output.

A little enclosure to hold the relay and several RCA jacks or other
connector of your choice is an easy project to construct.
