[Amps] Nice OM amps

[Roger (K8RI)]

Nice, but a tiny bit more than I'd want to pay.
When did the FCC permit 4 KW amps for the amateur service?
I use a single FU728F.  2 should be capable of 5000 PEP out.  Keep going 
and it'll be better than solar panels. <:-)

They are calling drive power, the input power.  IOW, with a 100W in they 
are getting 4 KW out. The input power at an optimistic 60% efficiency 
would be 6666.67 Watts.  Keep going and it'll be better than solar panels.

73, Roger (K8RI)
