Everyone knows it is important for the K3/100 to receive a solid DC supply.
If the supply drops significantly when high current is drawn several effects
may occur:
1 - The Transmitted signal becomes wider than it should be
2 - The power control loop is upset leading to unstable output power
3 -
Yes I´m beginning to think that K3 is more sensitive to PS
then other radios, right now it looks that way.
Then this should be in the manual!!!
What happens is if I have a bad signal on the bands I will
together with Elecraft get a bad reputation. I will of course
tell everyone what I´m running
As a good engineer I should have stated what I measure
with, sorry.
Normal 2-tone test, and a HP 8591E spectrum analyzer.
Normally I like to do it with speech, i e fully
modulate the radio and look at the sample 5 kHz
on each side. That is IMO better then a 2-tone test
since it will tell you
I used the included power cable and did notice a drop in the voltage
of about a volt. I had bought a 35 amp, 25 amp continuous Astron
power supply which has variable voltage but does not include a remote
probe as the one I made from the ARRL handbook offered. The probe was
used to ID voltage
The old TenTec attachments
were not as sexy as these PowerPoles but I felt they had more heft
and I didn't feel concern that someday the internal soldering would
come loose from repeated motion as the rig is located from one site
to another.
Interesting. At least on the newer T-T rigs, the

I recently used a heavy guage cable (#8 stranded, I believe) between the K3
and PS in a portable operation. The extra stiffness of the cable caused a
strain that fractured the plastic shell on the positive Power Pole connector
in the K3. So, I agree that some sort of strain relief is in order
