You don't really have to replace that resistor if you are willing to do
a
simple modification. I don't have the details at hand but the overall
effect is to considerably reduce the power dissipation in the Ranger
while
eliminating the 30K resistor. I made that change to my Ranger a year
ago
based on information I found on the web. I'll look it up if you want me
to
but you can probably get the info faster via Google "Johnson Ranger
modification".

Brian,
You can fit two (2) 15K in series in there.

I think you are referring to the Phil Salas, AD5X articles
http://www.ad5x.com/images/Articles/Ranger%20Mods%20RevB.pdf
I did these to my Ranger several years ago and they are great....
