What is it?

This is so easy even a Caveman could finger it out..... A clue? Solar powered.

We always knew ClassicCrazy was a Caveman!  Now it's confirmed!

Must have been the fancy model since it had an  LED backlight for display. Or was that LED cut through the board for something else ?

Some sort of rx linear?

The insides of a repeater ?

[Halfcrazy]

It sort of looks like the inside of a television transmitter? I see an swr bridge and a circulator etc but I don't see any indication of RX just TX

Some sort of rx linear?

Well actually a TX Linear but hey! Close enough. Slow project on the back burner. Found it this way...needs a total rewire as the "lamp cord" has gotta go!

A pair of MRF 154 RF Mosfets rated for 2MHz-100MHz. I'll be running it 1.8-30MHz. 1.2KW. 50VDC supply. Cabinet is a bit on the small side...might have to go bigger!

Some kind of lab power supply?  Battery "conditioner" for individual cells?

he already revealed it ralph as it is to be a solid state tx linear amplifier. i saw the balanced circuit in the negative picture and i didn't put it together as the combiner for the mosfet outputs. or was that for the input?

[ralph day]

So, even with the answer already provided/./.I got it wrong!  Says a lot for reading the posts instead of just looking at the pretty pictures

Niel, are you referring to this? If so that's the TX/RX relays.
