Re: [Elecraft] K3 Tune power issue on 15M only.
Tx Gain Calibrations must be performed - a pass - at the 5W level before proceeding to the 50W level. If the Tx Gain Cal failed at the 5W level on one or more bands, odds are one of the output or the driver devices are failing. Re-run the 5W Tx Gain Cal, copy the results to an email and send it off to Elecraft support for evaluation on Monday.

Re: [Elecraft] K3 Tune power issue on 15M only.
Good evening Dick, Calibration did succeed on 17M and output is FB-no issues. I have contacted support but thought I would continue to ask for help here. 73 K5RHD /randy On Sat, Dec 28, 2013 at 5:28 PM, Dick Dievendorff wrote: > I'd contact K3 support. > > There are band-specific low pass filters on the RF board that follow the > KPA3. > > How's your 17 meter output?

Re: [Elecraft] K3 Tune power issue on 15M only.
It looks like I spoke too soon. As soon as I got all settings redone, it went back into full power mode no matter what setting I chose from (13W-100) so I ran the transmitter gain Calibration at both 5W and 50W. Sure enough, it failed on 15M with the following: "5 watt calibration succeeded SWR 2.0-1 is too high for calibration SWR too high to continue calibration 50 watt calibration failed" So naturally, I checked my dummy load's SWR at it is 1.3:1 across 15M. KAT3 ATU was bypassed as well. Something is definately up with the 15M part of the KPA3. All other bands are healthy and happy at any power/mode setting. Anyone got an idea on this one? 73 K5RHD /randy On Sat, Dec 28, 2013 at 3:34 PM, Randy Diddel wrote: > After re-loading the firmware twice and restoring my factory settings, all > is right with the K3.

Re: [Elecraft] K3 Tune power issue on 15M only.
After re-loading the firmware twice and restoring my factory settings, all is right with the K3. Still a strange thing. I guess all troubleshooting starts with a firmware reload (or two) HI.

Re: [Elecraft] K3 Tune power issue on 15M only.
Hello, More info. I have checked the decimal point per one suggestion. I also now noticed that running JT65 on 15M, it claims 100 watts (full power) even if I set the power of the KPA3 to 15 watts. If I disable the KPA3 and run the K3 at 10W is shows 10W. Looks like a PA problem of some kind. Odd.

[Elecraft] K3 Tune power issue on 15M only.
Hello Elecrafters, I have been spending some quality time tuning my vertical and getting the bands closer to resonance today. I have gone into the Config Menu and specified Tune Power to 10 W. All bands, 80-6 obey the setting BUT 15M, no matter what setting 10, 25, 50, 100W, or NOR, it shows 100W output on the LCD. I don't have a wattmeter so I cannot verify if this is true or not. Bug, known issue, or undocumented feature? Latest and greatest firmware, DSP, etc. Thanks, HNY, and 73 K5RHD /randy __ 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
