Question:
I am finding the following on my QRP K2 with KAT2, cal current set 3.7: 20 meters power setting 14.6, current displayed 2.84, CW 30 meters power setting 14.6, HI current displayed at CW TX, SWR 1.2:1, current 3.74 40 meters power setting 14.6, Hi current displayed at CW TX, SWR 1.2:1, current 3.72 Should I consider this as OK? Or do I have an alignment issue on 30 and 40 meters or some other issue I should look into? The ant. on 30 is a vert, on 40 and 20 a dipole cut for 40 and 20. I am in the process adding the upgrade to K2/100 and do not want to create smoke. Thank you for your consideration.

Dick,
That current is definitely too high (except on 20 meters). The most common cause for that symptom is the Low Pass Filters. Do count the number of turns on the toroids in the LPF area - count each pass of wire through the center of the core as one turn. I believe you will find you have one extra turn on the toroids. A straight wire through the toroid center is one turn, a complete wrap around the core is two turns. 73, Don W3FPR richard gilley wrote: > Question: > > I am finding the following on my QRP K2 with KAT2, cal current set 3.7: > 20 meters power setting 14.6, current displayed 2.84, CW > 30 meters power setting 14.6, HI current displayed at CW TX, SWR > 1.2:1, current 3.74 > 40 meters power setting 14.6, Hi current displayed at CW TX, SWR > 1.2:1, current 3.72 > > Should I consider this as OK? > Or do I have an alignment issue on 30 and 40 meters or some other > issue I should look into? > The ant. on 30 is a vert, on 40 and 20 a dipole cut for 40 and 20. > > I am in the process adding the upgrade to K2/100 and do not want to > create smoke. > > Thank you for your consideration. > Best regards > Dick AD1G > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > ------------------------------------------------------------------------ > > > No virus found in this incoming message. > Checked by AVG - www.avg.com > Version: 8.5.409 / Virus Database: 270.13.80/2349 - Release Date: 09/06/09 05:51:00 > > Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
