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.

Garey,
I feel that I've got a good handle on this radio, and thank you for your support. Once I get a 3.3 ohm resistor in there, however, and assuming the meter series resistor no longer sets up an accurate 100 ma reading, is there a way to calculate the proper resistance, or is it just easier to wire in a pot temporarily to figure out the correct value?
