Well I just ordered replacement fuses for the Powerwerx adapter. Looking at
the power requirements of the K3, I thought the 40 amp fuses supplied were a
bit too heavy. I had some 25 amp fuses here at home but I thought they might
be a little light for the K3. I decided to purchase 30 amp fuses to u
I was not sure about the power drop question when I purchased it. My astron
is about 4 feet from the radio on the floor. I am not sure how long the
standard Elecraft power supply cord is but the Powerwerx adapter adds an
additional 1.5 feet. My K3 now shows a voltage of 13.6 volts, a drop of .2
vol
It's too bad the overall length isn't 4 or 5 feet...with the additional
length on the APP side of the fuses. That would be more elegant.
The way it is now, you have one voltage drop going through the fuse,
another going through the APP to APP and then the APP at
the radio. Then multiply by two
I purchased the power cord with fuses from Powerwerx, item RGH-10 -

- It is hooked up to my Astron RM-35M and I use the Elecraft provided
power supply cord from the fuses to the radio.

The standard, for vehicles, is to connect to the provided binding post, then
run absolutely no more than 18 inches unfused. This allows the fuse to be
placed for access. It also allows for shorted wires.

I thought that's what I said ... if I didn't, I was wrong ... as close
to the power supply as possible. Many present era power supplies have

Lee,
What size wire are you using ? Should not be smaller than
#12.
The length should be as short as comfortably possible.
That means as short as possible with enough extra length
to dress the cable around the operation bench if/as needed,
and to be able to pull the radio out of its operat
I will differ with Fred - the fuse should be mounted close to the power
supply - you are protecting the wire, and not the radio.. There could
be a fault in the wire (actually more likely than a fault in the radio),
and a fuse at the power supply end will trip - think about a fuse at the
radio

Questions.
1. Do you need fuses to be in both the positive and negative lead? Or, since
I
am a "fixed" station, can I get away with one fuse in the positive lead?
Currently, I have both leads fused.
2. What length should the pow
