I have the dual directional coupler and the indicator unit in very nice
condition. I also have a separate unit wired as just an SWR indicator built
into an LMB CABINET. It also uses the original MicroMatch meter.
The 252N1 indicator can be easily updated to the 261 by adding a stereo plug
and an SPDT switch to the top of the indicator unit. That way it can measure
both forward and reflected power. The LMB unit is already wired that way.
I calibrated it at 100W on 80M and it was dead on at 15M.
