I spent a fair amount of time playing with it (I did a pre-order on Friday online). I also was able to talk to Ranko a bit about the design, especially the fan noise. During Gerald's initial video you could hear the fans ramp up during each tx cycle.Amp is slightly wider than the radio and deeper. Looks nice.
Here is a link to a few pictures
I did a couple of videos showing the amp in operation. I was concerned with the fan noise after hearing Gerald's original video. Ranko made improvements to the amp to reduce noise. The internal power supply was upgraded to 3.5 kW and includes two cooling fans dedicated to the PSU. The heatsink for the RF deck is very goo with two fans cooling the heatsink and one fan cooling the RF components.
Unfortunately it was very noisy in the building. The fan noise did not exceed the ambient noise under normal operation, even when 6 inches from the amp.
Here's two videos which were done by sending series of dashes at 1800 watts out.
Power line voltage at the amp was 209 VAC and dropped to 204 VAC during 1800 watts out. The amp had no problem putting out 2200 watts into a load but I wouldn't recommend it :-)
There are two RF in, Two RF out, two keying inputs, two -60 dBc sample ports, two CI-V ports, two CAT ports, and Ethernet.
Amp is set for SO2R out of the box.
It will have control integration with SmartSDR or you can use an Android app or PC app. They did not have the PC app on display.
