Hello all, This is my first post to the group so I hope it works correctly!
Happy to report that K2 S/N 5556 is alive in Australia! However I'm slightly concerned about the results I'm getting during transmitter alignment. After running through the TX alignment procedure twice the best results I can get for max power out are as follows: 80m - 8.1w 40m - 9.6w 30m - 10.8w 20m - 14.5w 17m - 13.6w 15m - 9.1w 12m - 10.5w 10m - 10.6w These power figures come from the internal K2 power meter but a CB radio pwr/swr meter connected between K2 and 50 ohm commercial dummy load agrees with these figures with surprising accuracy. The question being are these output figures 'normal'? Output on 80m, 15m and perhaps even 40m seems a bit low to me. Simply because I'm expecting to see 10w or more on each band. In addition I got a 'Hi Cur' warning are soon as I raised the power level to maximum. My K2 consistently draws 2.69A on all bands according to the digital current meter in the power supply but the K2 current meter registers values from 2.52A to 2.54A. I'm inclined to believe the K2 but as yet have not checked the current draw with a meter. I have for the moment increased the 'Hi Cur' warning threshold to 3.0A. Again, same question, is this current draw 'normal' or abnormally high? I have double checked the 80m bandpass filter components, toroid type/number of turns and the capacitor values and all appears to be correct. So I'm not sure if I have a problem or not. A sincere thanks guys for all your combined help getting me to this point. No I haven't posted to the list before but when confused (and that happened regularly !-) my questions were always answered by the list archives!
