Hello Rick,
I'm glad I could help. It seems you are very close to closing the box, and making 1st CW QSO with the K1. If you have the antenna connected and the band is open, we can try to set a sked, so I can contact Long Beach(just checked QRZ.com). My lot is small as well, and my main antenna is a WIMO GP with radials for 15m/20m, and now it is cold I have installed in-house below the roof an inverted V, loaded with coals to make it fit below the roof. Anyway, good luck with the K1, I made so far in~3 months >50 CW QSO's, worked many new countries, it's really fun, and so nice quit to listen through the 200Hz filter. The nicest contact so far was VK4.

I sent off an email to Elecraft yesterday when I posted this and no answer yet, maybe I will call them and talk to Scott there. I have to get a couple of speaker slides, heck those things are small! I even played with the 40m section and got another watt out there also! Can I live with 4.4 watts on 20,maybe, but if I get more pwr out, even better. Thanks again for the info Rick/WA6ES Marc PE1FJN wrote: Hello Rick, HNY2010. When I had output power problems at 15m, not at 20m, I increased the output power by 'tuning' the low pass output filter (L9/L10, L11/L12), suggested by ELECRAFT. By bringing windings together I was able to get the required output. It does not look as nice when having the windings evenly spread, but in the end the output power is more important. Make sure you have a dummy load when checking Pout, as when VSWR is poor, depending of the COAX length you will see high or low max output power on display K1. Reason: K1 is measuring Vpeak out, and calculates it back to power. So reading on display is only reliable when you have 50ohm, or have installed the internal antenna tuner. Also make sure you have 13.8V, Pout max between 12V and 13.8V makes a difference. I run it at 12V, Power is 5W at 15m/20m band, while running at 13.8V I can easily get up to 7Watt. For me 12V is fine. If tuning of the coils does not work, contact elecraft support, and refer to power problems from PE1FJN October this year at 15m SN: 2761. I changed 1 resistor on instructions from ELECRAFT. At this moment I have now no access to this mail(sorry), but I'm sure you will be able to get the same instructions. Having changed this resistor power was very fine, and not marginal anymore. Hope this helps, 73 PE1FJN Marc K1 SN:2761 PS: Good Luck, at 20m DX is really nice with this RIG. _____ View message @ http://n2.nabble.com/K1-Low-power-tp4248493p4253616.html To unsubscribe from Re: K1 Low power, Suggestion to increase output power, click < (link removed) vbWUubmx8NDI1MTY0OXwyOTg2MTMxODQ=> here. -- View this message in context: http://n2.nabble.com/K1-Low-power-tp4248493p4256646.html Sent from the [K1] mailing list archive at Nabble.com. ______________________________________________________________ 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
