I have a couple of questions about the KPA1500's internal tuner. For the most part, I leave the tuner inline. Except for two sub-bands (SSB on both 40 and 80m) I am well below 2:1, and maybe 2.5:1 at the top end of 160m. The KPA does a good job throughout.
The problems/questions arise when I need to transition between the KPA's internal tuner on the bottom ends of both 40 and 80, and the external Palstar HF-Auto tuner, which I need to wrangle very high SWRs on the phone portions of those bands. Obviously I don't want both automatic tuners inline at the same time. The situation is most acute on 40. The HF-Auto (external automatic tuner) is bypassed everywhere except the range of 3650 to 4000, and 7100 to 7300. I would like to automatically have the KPA1500's tuner go into bypass at the above ranges, just as the Palstar auto-tuner bypasses outside of those ranges. Is this somehow possible, or must I manually switch the tuner in and out when I cross the appropriate thresholds? Second question, and I think this relates to the whole "bins" thing, which I don't understand, relates to having different tuning solutions on the same band segment. This could be handy for me on 80m. Unlike on 40, for 80 I have an inverted vee, and it's easy for me to drop the ends and change the length of the antenna, so that instead of being resonant at 3550 I could make it 3700. I did this for the ARRL-SSB contest and it worked pretty well. Is it possible to have two different sets of memorized tuning solutions in the KPA-1500, in the event I have the vee set for CW (normal) or SSB (for phone contests only)? --------------------------------------------- 73 and Good DX Peter, W2IRT President, North Jersey DX Association DXCC Card Checker Letter O Manager, ARRL Incoming 2nd District QSL bureau ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
