Re: [Elecraft] HI current 30 meters
Thanks for your insights. I'll take a look at all of what you have suggested. I use the 20 watt scale, the next lower scale is 5 watts. The K2 and the wattmeter agree on 10 watts on 30 meters, it's just the amount of current that bothers me. I appreciate your help.

[Elecraft] HI current 30 meters
I bought a K2, sn 01489 on ebay. Had to replace the PA transistors and drivers and R50. Upgraded the firmware. Anyway, on 30 meters, at 5watts, it draws 1.56a. At 10 watts, 3.42a. Also a bit high, I think is 40 meters which at 10 watts draws 2.46a, and 15 meters at 10 watts, 2.30a. The rest of the bands range from 1.80a to 2.14a at 10 watts. This is into a dummy load. Any suggestions would be appreciated. -- View this message in context: http://elecraft.365791.n2.nabble.com/HI-current-30-meters-tp5672958p5672958.html Sent from the [K2] 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
Re: [Elecraft] HI current 30 meters
Sorry, Don, I don't have the hang of this forum yet. My K2 is a bare bones unit with the exception of the audio filter. I have a Diamond SX-200 power meter and an MFJ-280C dummy load. It could be that it is wired for max efficiency at 5 watts, but even at 5 watts, 30 meters stands out with respect to current drain. At 5W, 30 meters draws 1.56a. The next closest band is 20 meters, 5 watts, 1.36a, and the lowest current drain is on 12 meters at 1.24a. I'll check those items you suggested and let you know how it goes.
