[Elecraft] KXPA100-AT observations

[Kenneth A Christiansen]

Hi to the group

A few days ago someone asked questions about the KXPA100-AT and at the time I wished for the same information. I got mine yesterday and I am looking forward to using it on the SKN tonight and tomorrow. I have it hidden behind the second monitor for my computer so my station now gets out better but it still looks the same.

Frequency                                                      14.025 mhz
My power supply is set for                            15 Volts
The KX3 receive is                                           0.198 Amps
The KXPA100-AT off draws                             0.001 Amps
The non transmitting but on amp draws         0.382 Amps
The amp putting out 12 watts                         4.9     Amps
The KX3 set for 100 watts out                         1.415 Amps
The KX3 and KXPA100-AT at 100 watts out  15.8 Amps
 Drain shown in the UTILITY                           13.0 Amps 
Dropped voltage to 12.0 volts and current      15.0 Amps at 100 Watts
Drain at 12 Volts read                                      11.4  Amps at 100 Watts

Please do not attack the accuracy of the measurements. My digital meter can not measure over 10 amps so the lower current measurements were made with it and the higher current measurements were read on the meter in my Alenco DM-330MV power supply. 

I do a lot of camping using a large battery. I feel this should be comparable to how my K2 and it's 100 watt amplifier performed. 

I hope this information is useful to the other hams that are interested in how the KXPA100-AT performs.
