Problem with KPA100 - HiCurr
Locked
 
|
Dear all,
After a lot of checking and checking I still have this problem. I removed T4 and did dubble check. I did replace the coax cable by a teflon coax cable. I did set R26 and R27 to 43K. Sometimes when turning C1 it is possible to set 1.0-1 but than it reduces the power to 0 watts. After switching off and on again the display is saying Hi Curr again. Any other suggestions? 73, Koert PA1KW ----------------- "HAMRADIO - when everything else fails!" Koert Wilmink wrote: Dear all, I just finished my KPA100. I do have the following problem with the first steps connecting the KPA100 to my K2 #05618. I've connected the ribbon cable, speaker and RF connector to my K2. I've got audio and I also receive stations when I connect my antenna. With my dummy load and after setting power to 5Watts on 40M I see the 5 watts and the SWR for 1 second in the LCD screen and then the HiCur (High current) appears on the LCD.On 20m bands I only see the PWR in the LCD screen without the SWR for 1 second and than I see HiRefl. On 10M I do see the pwr and the SWR! The latter I only get 2.1 watts when set to 5 watts. Please can somebody tell me where to start? I did check the connections and this seems to be ok. There is no pwr to the KPA100 so everything is bypassed, except the bandfilters? help is very much appreciated!. 73, Koert PA1KW ----------------- "HAMRADIO - when everything else fails!"
