The amplifier I am using is a commercial unit made by Unique Broadband Systems (UBS) here in Toronto, Canada, originally for Sirius XM base station repeaters.
They have an extensive R&D lab and manufacturing facility on site, for commercial and military customers.
The owner is also an amateur radio operator. I have permission to say that the company would like input\s from the EME community for what they would like to see in a high power amplifier. They could offer a reduced cost version with a built-in front panel display of amplifier status, power, temperature, vswr, etc.
They can make anything 50 MHz - 10 GHz. A production quantity of 8-10 units would be accepted by them as a minimum to do a custom design and manufacturing.
My question for the EME community: What bands would you be interested in, what features are needed (PTT switching, USB control, etc.). If a list of specifications can be agreed upon, I could forward this to the company. I think it is great that they would be willing to support the amateur community with a specialized amplifier for EME work.
