[Johnson] 250-37 directional coupler

[C E]

Hi Steve:
I think you can go to the ARRL handbook and find a
directional coupler that will take the place of the
'37. The coupler (if what I think is right) rectifies
and turns the sampled rf into a DC level and sends it
out to the meter for your SWR or relative power meter
