Julius, I also strugled with this and made a small Excel file to calculate at which frequency this birdie will be. File can be found at: www.pc5m.com\projects\resources\kpa100_xtal.xls
At the top you can input the x-tal freq used in the KPA100 and below it will calculate the mixing products (up to 5th level). If a cell turn red than the spur will be in-band ! It turns out that NO x-tal (in the vicinity of original one) will provide birdie free operation on all bands, but depending on your preference you can position this birdie on the bands/frequencie best for you. In my case I changed the x-tal to 16.0 MHz gl, Carel, pc5m ------------------- Just out of curiousity, after spending some time on 10M during ARRL 10, I noticed a birdie around 28.019/20. Is there a way to eliminate this or move it below 28.000? As to my high current draw on 160, the KPA100 works fine into a dummy load and straight into the antenna. It does seem to draw more with the KAT100 in the circuit. I can't imagine much in the tuner that would cause such a problem (although I could be wrong). My thoughts drift towards a ground loop issue and/or rf getting back into the rig's control circuit. Guess I will be adding some further current chokes in the shack... Best wishes to all for the holiday season. May 2007 be good to you and yours...
