[Elecraft] K2 on 160m with battery power?

Mon Mar 11 11:30:01 2002

Dave, Pierre,

I have the same problem on 160m . High current and max. output power of  4 Watts.
I have  also noticed that  PA output transformer is getting warm if I Keep  K2 on transmit for 20
seconds or longer.
This happens with P.S or battery.
I didn't have a chance to check LP filter yet.

73!

Hello,

My K2 is drawing a lot of current, on 160 W. I cannot go above 3 W, and it
draws 3 Amps, on a 50 ohms dummy load.
This is not changing, if I connect it to a battery, or to an external power
supply, even at 15.0 Volts. In addition, I can see that the Volts, on the
display, are  wandering around, despite the stability of the power supply
itself.
N6WG suggested that the Low Pass Filter is not set where it should,
therefore the low power. (BTW, thanks for the suggestion !)
It can make sense. However, I had no time to check the LPF, with the antenna
analyzer.

Regards, Pierre
