ENI 2 kW amplifiers - any interest?

[dave]

I have a couple of ENI 2kW RF pulse ampliers, designed for MRI. I believe they cover the 15-64 MHz range, but can almost certainly be modified to extend up or down a bit. I’m wondering if these may be of any interest for amateur radio. These are billed as pulse RF amps, so I’m not sure if some kind of derating needs to be applied for CW use, but I can say that they are pretty beefy, at about 100 lbs each, and require 240V. If one or both would be of use to the space, please let me know.

I’d be interested. I’ve never run QRO before.

I’m thinking there may be other applications too…

Great. If we have a dedicated space (do we have a ham shack?) and someone taking charge, then I’ll bring them by. I just want to avoid having them sit around on a shelf with no purpose (like right now in my lab,)

We no longer have a Amateur Radio Committee, nor a ham shack (it is in boxes). In order to donate these (or loan them) to the space, you need the permission of the committee chair who would be responsible for them. The most appropriate would be @Lampy the chair of the electronics committee.

Would these replace the Plasma Coat PSU’s?

We could try and build a RF CO2 tube. I have a couple of 35 watt RF CO2 tubes we could model. Most run at 15MHz.

Yes, that’s why I posted here, and why I would have to see a concrete project, dedicated space, and a person in charge.

I don’t think so. While Plasma power supplies may operate at RF frequecies, the output stages (I believe) are designed to generate an arc, not for true RF impedance matched RF signals.

Possibly. These are designed for precision pulsed and modulated MRI RF signals, with 2kW peak power, so it may be possible. Some energy may be lost in the impedance matching. However, whoever takes this on should know what they are doing, since it’s a lot of power, potentially very dangerous. Also, poor impedance matching could cause large reflections and damage the amp. Also, that’s a pretty powerful laser, potentially dangerous as well. So obviously nobody should try it. . .

It could also be used to power up to 40 metcal soldering irons simultaneously.
