[Elecraft] K3 - what power supply are you using?

[Jim Wiley]

Yes.

You should also consider a 35 to 55 AH (or thereabouts) Gel-Cell battery 
and a 3 to 4 amp automatic charger.  Advantages:  (1) Instant emergency 
power good for several hours, (2) protection against line spikes 
(surges)  and dips (brown-outs),  (3) the small charger will make up the 
"daytime" discharge overnight without needing a much larger main power 
supply, (5) generally, while system ends to be rather less expensive 
overall, and  (6) the battery acts like a huge ultra-capacitor that 
absorbs "junk" on the circuit powering the radio which helps with hum 
issues and such

I ran my entire station from such a system for years. The station 
consisted of  a 100-watt HF rig, a 50-watt 2-meter set,  35 watt UHF 
set, a Heath WWV receiver/station clock, audio processor, and several  
accessories, all from a 10-ampere automatic charger and a single Costco 
deep-cycle Marine battery.

Any time I wanted to add something, I just hung it across the battery (I 
actually used a home-built a DC distribution panel) without worrying 
about needing to add yet another 12-volt power supply of some type. 
Also, didn't have to buy them - a savings that adds up to quite a bit 
after several rigs are added to the station.
