Elecrafters,

 

While reading the thread re: charging batteries I saw the note re: adjusting
the Astron.  

It occured to me that I could bump the ouput up from 13.8 to the "legal
limit" for my KX1.  The goal of course is "more power" out!

 

Is this a bad idea?  I say "bad" because I know that many will say that
small increases in power are not of much value given the nature of decibels
and the human hear, but unless this is a "bad" idea, I prefer to experiment
and see what results I get!

 

The ads for my RS-70M say it is adjustabe and my schematic shows a 20K ohm
pot on the input to the V meter  and a 500 ohm pot on the input to the I
meter.  I have not popped the top of the ps yet so I don't know what visual
inspection will reveal.  After I get some feedback on my idea I'll take a
look and see what I can do!

 

BTW, my Kenwood TS-570D specifies 13.8 VDC plus or minus 15%.  This gives me
a ceiling on 15.87.  I am only going to 14.2 for KX1!  I run them both of
the RS-70M when I am operating from home.

 

Thanks,

Jack, AE6GC
