Hi, everyone.

Well, I'm now re-thinking my power supply dilemma, and may not need to go 
out and spend the money for a new one after all.

Here's the latest scoop:

When I took the voltage and amperage readings last night, I thought it would 
be sufficient to somehow clip the leads on my Omega talking meter to the 
lugs on the Astron RS35.  This is where I got the really strange and 
variable readings when putting a load into the circuit.

However, and this is a big however, tonight, I figured out a way to squeeze 
the leads in so that they could connect directly to the rig runner terminals 
themselves, and that made a big difference.  My voltage without any load 
still remained at 13.35 or so, but the voltage when transmitting on full 
power was much more stable this time, ranging from a low of 13.0 to a high 
of about 13.20.  I then took power readings with the TS590's meter on full 
power, and came up with 100 watts.  So, if there is a problem here at all, I 
think it might be simpler, and might merely take the form of terminals that 
meed to be either cleaned or replaced.  You wouldn't think that would make 
much difference in voltage readings, but apparently it does.  I am not sure 
why I initially kept getting those 50-watt power readings earlier in the 
week, but now, I'm less convinced that there is a major problem with the 
supply.  Obviously, I'm going to have to take things apart here, clean and 
secure everything systematically, and then see if the problem recurs.

At any rate, it beats spending money on a power supply that I simply may not 
need, at least right now.
