It seems to me that it would not be in
Motorola's interest to provide capabilities
to use old equipment when they could sell
you new equipment instead.

The MOV I used is labeled GE N4 130L20
The spec sheet from Littlefuse/Harris/GE
says that the 130 is for RMS voltage.

I added a 130 Volt MOV across the hot and neutral
of an Astron 50 Amp power supply for a repeater
and had an interesting effect.
We lost AC power and switched over to the generator.
When the load was added to the generator, the Onan's
voltage sagged a bit and the throttle opened to
bring the spee

They also did some interesting trade secret things.
Many of the hams they hired in the past were not
able to service the equipment and left them with the
bias against hams.

When I got a job in the 1970's at a big LMR shop in Southern
California, they told me they almost didn't hire me because I
had an Amateur Radio License. They were unimpressed by most
ham's skills.

I'm in from 1985 (Detroit, Michigan).
I think I sat for my First Class in Long Beach, CA in 1977.

An alligator is a critter will a big mouth and tiny ears;
an elephant has bigger ears.
An alligator repeater is heard further that it can receive.
An elephant repeater receives further than the repeater
transmitter can be heard.

Just curious, what is the current drain of the LVD 12-30 and LVD
12-75 when operating? Have you had a chance to measure it? It
isn't mentioned on their spec sheet.

One technique I haven't seen mentioned,

administrative capabilities.

I remember back in the early 1960s going to the local home and

to show us the new Touch Tone service they were preparing us
for. They had a demo with step and pick relays on one side and
DTMF on the other. You got to dial
Just a personal experience with residential Internet:

The power went out. Our PCs and cable modem were on UPS. I
brought the PCs down gracefully and waited.
After a half an hour, I started my generator and booted the PCs.
It was about an hour after the fail
You can get close with minimal equipment.
Here's one I did (2 meters, 600 KHz spacing).
Start by doing each cavity individually.
I used my old Motorola S-1318-A signal generator
to the cavity with a Tee connector, then to
a UHF Tee connector with the Tee'd pin
unscrewed, then to a dummy load.
Thanks, got my BNC pigtails in good shape today.

I would watch the wobble when the wind blew and

When I brought it down I discovered the four pins

You weren't kidding about New Old Stock. When I opened
