Hi David,
My guess is that the walwart is unregulated or has very optimistic
specs. You could also be getting RF back into it. I never power serious
radio gear with walwarts, even HTs. There's too much junk out there.

I am in the process of getting familiar with my newly acquired KX3 purchased
for POTA and am enjoying it immensely.
I am powering it with a 14.8V, high quality, Yamaha walwart - very little
internal noise. Settings indicated in the VFO B display area using DISP are
normal.
When I set the PWR level to 10 watts and then key the xmtr, the power
immediately drops to 5 watts. With the key down, I am monitoring the VFO B
display which indicates a drop from 14.8V to 10+V and 1+A. That makes it 10W.
If so, why does the reading when I push in PWR drop to 5W? Is that ‘input’
power vs ‘output’ power, ie, 50% efficiency?
If that is true, how does one achieve and maintain 10W of output power?
Any help would be most appreciated. Feel free to RSVP here or call if you like
- or send me your number and I’ll call you!
Tnx es 73, David, NS4V
