[Elecraft] K Line Power Requirements

[Jack Regan]

The specifications according to the manuals are:

 

K3                          20.0  A (recommended) 3-4 (typical)       NOTE:
When barefoot I run 100 Watts for CW, SSB and RTTY

P3                           00 .5 A   

KPA500                 20.0  A

 

FT-7800                00.5 A    RCV
NOTE: 6M, 2M, 440. Squelched. I sometimes have this on scan when working HF.


08.5 A    XMT                                                       NOTE: I
do not think I have ever transmitted on both at the same time.

 

Do I really need a 49.5 amp continuous output PS?

I have an ASTRON RS-70M that has been running for 10 years with no problems.
I was hoping to get a smaller, lighter supply to help simplify my setup.
This is one of the reasons I am thinking of the KPA500, in spite of its high
price.

 

One alternative I am considering is the MFJ-4245M.

 

Any advice and/or suggestions would be appreciated!
