[Kenwood] RE: Power Supply for TS-130S

[Hsu, Aaron (NBC Universal)]

The Astron RS-35A is a great choice and can be had for under $130 (shop around or to go a HAM fest/swap).  The main advantage of the RS-35A is that it's a linear power supply - no RF hash of any kind.  But, it's quite heavy - lots of copper in that transformer!

Switching power supplies are convenient and *light*, but are RF noisy by design.  Some companies filter out the hash quite well, but others don't do such a good job.  I have both RS-35's and a SS-30M switcher for portable use.  I can hear the SS-30M's hash on a Kenwood TS-850, but it doesn't bother some other rigs which may not be as RF sensitive.

Given the choices listed below, I'd go with "none of the above" and choose an Astron SS-30M (for compactness) or an RS-35A if it's not going anywhere.

Subject: [Kenwood] Power Supply for TS-130S 
 
I will be purchasing a "gently used" TS-130S from 
another ham. What type of power supply do I need 
for it? 
 
The TS-130S Instruction Manual states ... 
 
"The TS-130SE requires more than 18A at 13.8 VDC 
when transmitting with full power. Use the model 
PS-30 power supply for fixed stations." 
 
Since finding a functional PS-30 power supply might 
be hard, what other power supplies would be compatible? 
Would a switching power supply work? 
 
How about ... 
 
MFJ-4322 - regulated, switching, 13.8 VDC at 22 amps 
surge, or 20 amps continuous? (List Price $99.95) 
 
MFJ-4125 - regulated, switching, 13.8 VDC at 25 amps 
surge, 22 amps continuous (List Price $109.95) 
 
Kenwood KPS-15 - switching, 13.8 VDC at 25 amps surge, 
or 23 amps continuous? (List Price $143.55) 
 
Suggestions??? 
 
Thanks & 73,
