KPA-500 and a K2

Ken Miller K6CTW
All,

Just wondering if anyone has tried driving a KPA-500 with a K2?  If so what output did you get at 5 watts in?  10 watts in?

Thanks in advance for any ideas/data.

73 - Ken Miller, K6CTW
K2 # 455

I drove a KPA500 with a KX3 with 10-watts drive.  I think I got out about 175 watts or something like that.

The KPA500 is linear, with 13 db gain. That means the KPA should output about 20 x the input power.
So, for 5 watts in, you should get about 100 out, for 10 in about 200 out.  There are slight variances due to the KPA's input network.
Also, be sure to check what the  transceiver is putting out compared to what it is indicating. Amazing how often power calibrations are needed.
