KX1 power output
Locked

Howdy,
After a long break, the summer, I finally finished my KX1 #2140. Two rookie mistakes but I finally figured it out. I installed the KXAT1 tuner and had a question on the output power indicated on the RF scale. When I am running on batteries the power output on 20m is 2 bars or if I understand the manual correctly that would be about 1 watt. Using my AC adapter I get 4 bars or 2 watts. On 20m I get 2.5 watts on the batteries and 3 watts on AC. Does this sound about right? Next, when you change bands I believe you have to tune the antenna to the new band is that correct? The cw study is coming along but I don't feel confident enough to give it a try just yet. Thanks in advance. 73, Ed KE7HGA |

Ed,
The LED bargraph indicates approximately 1/2 watt per bar, so yes, 2 bars = 1 watt, 6 bars = 3 watts and so on. The KXAT1 will remember the tuning for each band, so after you do an initial TUNE to match an antenna on any one band, there is no need to do a tune after switching bands. *However* if you have changed the antenna for that band, a new TUNE cycle is required. Good luck on the CW. Start slow and don't be afraid to make contacts - there are many forgiving ops around (but a small number who are unforgiving as well - ignore them, for they should be ignored). 73, Don W3FPR EMD wrote: > Howdy, > > After a long break, the summer, I finally finished my KX1 #2140.
