Yes, I agree with you in regards to the UHF Micor and MSR 2000.
The UHF Micor microstrip circuitry are all 50 ohm in/out sections.
Very handy for trouble-shooting too I might add.
I usually use a Bird Wattmeter for this ... and have a 1 watt slug
which makes it that handier.
In my request, I should have added the 150.8 - 174 MHz range boards.
Thanks for your comments,
