[amsat-bb] Is This a Connector? If so, what kind?

[Norm n3ykf]

RF connectors are "N". The single pin animals (for power and signal)
are feed through capacitors. Helps keep noise and bad stuff out of the
power supply/signal input chain. Less of a mess to deal with at RF.

'PQL makes nice kits. Well documented. Currently building my way to a
pair of amps (VHF and UHF) for the B210.

The ultimate amp control board will do many of the amp control things
natively. SWR sense, lockout, sequence (DC power, bias, RF power and
holdoff, in that order and reverse for unkey)

Relatively inexpensive to buy this kit. Slightly painful to build as
it's SMD. Ring magnifier at a minimum. Best with a stereo microscope.
The right tools make the job almost painless.

His analog method of doing timing for the control board is pretty
neat. Spent a few hours contemplating that circuit.

Uses an LM35 to do temperature sensing. My amps run out on the edge.
Best place to run (cleanest) them per the data sheet. Does mean that
there's not a lot of headroom for errors and oopsies.

Using VI cor 24VDC in-> 12V 5A bricks to run the chips and
electronics. Paneltronics has 24V 5A circuit breakers to stop any
power supply craziiness.

I used Phoenix Mecanno enclosures with integral card slots. Not quite
as pretty as a custom milled enclosure.
