I've known of some private shops who wouldn't hire a ham because the owner
thought hams did too good of a job. Those owners thought that hams took too
much time trying to get the last tenth of a watt out of a transmitter or too
much time tuning a receiver for that last one hundredth of a microvolt
Did Fred use locks? Perhaps that was your point. I don't remember locks on
the mobiles or upright base stations that I had. Seems like the mobile
covers went on and off similar to the GE twin coffins (which I don't
remember requiring a key). It's hard to remember the details of those radios
except
What's the key number or other stamping? Now I'm going to have to look thru
my key collection and find it. Somewhere I have a picture of me sitting next
to my Link six meter base station, but the radio and all the spare
transmitters and receivers and the mobiles are long gone.

You would need to provide more information for us to run the plots.
Including:
Antenna height (looking at your website pictures I presume around 300')
Effective receiver sensitivity (taking into account the noise floor etc)
Duplexer, isolator and any filter losses.
For the other unit, its receive
How about the TX RX Systems 28-69-xxx series of duplexers.

I don't know the current situation, but for years the antennas were inside
the building because the Forest Service would not allow them on the outside.
Around 1971 when the 2m repeater was first installed, we couldn't even
acknowledge where the repeater was located. At one time some years back,
Over the years I thought I had seen it all. That one takes the prize.

Here's a link to a photo I made during a recent service call. Someone
has cut the Heliax to our UHF receive antenna and spliced a piece of
RG-58 to it.
I replace the Polyphasers at the sites I'm responsible for every two years, or
sooner if a direct strike is suspected. Just because they pass RF OK doesn't
mean they're still doing the job efficiently. I believe it is cheap insurance
even it means replacing a half dozen or more at one site.

I believe you could test them with a Megger, but you would also damage the
device at the same time. If it wasn't damaged before the test, it would be
after the test. That's why I have just replaced them rather than try to test
them.
