Garey,

 

Yes, it is a T-4XC.

Eric -

A pot is easier, then put in the nearest standard value. You can use 5%
carbon film resistors which are usually MUCH more accurate than that,
selecting one from a group if available and necessary. Again, the
meter is no precision device, but it is pretty repeatable at a single point.

I have a little test box with a 10 turn pot and Bourns 10 turn counter
dial so I can set it and read the resistance right off the dial. Most
are in the 100 - 300 ohm range.

Just to be sure, we are talking about a T-4XC, correct.? There have
been several transmitter threads lately! :-) The reason I'm asking is
the T-4XB used a 2.7 ohm resistor.
