Hi,
After having been off the air for about a year (moving house; other
interests) I have recently fired up my KX1 again. When tuning up a
random length of wire, I noticed that the output power indicated by the
KX1 ATU was only 0.4 to 0.5 Watts (while SWR was good: 1:1.0 to 1:1.1).
I attached a 50 ohm dummy load and hooked up my oscilloscope and saw a
nice 24V peak-to-peak voltage on key down. That's 1.4 Watts and IIRC not
bad for a battery-powered KX1 (battery voltage indicated by the KX1:
8.5V on receive, 8.4V on transmit).
Why then the low power indication by the ATU?
I have already taken the unit apart and have resoldered all solder
joints on the ATU PCB, but to no avail. Does anyone have any ideas?
Thanks in advance,
73 de PA4N
