Re: [Elecraft] K3 HI-TEMP ALARM
Wayne & Gary, Thanks for the support off the list. After I set PA TEMP to "R ONLY" instead of "T AND R", the problem stopped. I don't know the reason why. But anyway it seems usable with this setting for the time being. Jaakko, Please try this setting on your K3 too.

Re: [Elecraft] K3 HI-TEMP ALARM
In my experience with this, the five watt calibration of the K3 was incorrect. The gain required to set the fifty watt cal was then incorrect. This can cause various problems, including burning out the low power amp, and not getting 100 watts out when 50 is calibrated. Note that a Bird wattmeter with a 250 watt slug is NOT sufficiently accurate at 5 watt levels.

Re: [Elecraft] K3 HI-TEMP ALARM
Hi folks! Thank you for suggestions. In my previous post, I forgot to say that my K3 works without hi-temp alarm after warming up (about 30min or so without transmit just receiving status). So, it's just the same with Jaako's case. My shack temp was around 15C these days. hmmm...

Re: [Elecraft] K3 HI-TEMP ALARM
Atsu, Try re-calibrating the PA Temperature Sensor as described in the manual. Also make certain both fans are turning. 73, Don w3FPR JE1TRV wrote: > Hi Elecrafters! > > I have problem on my K3/100 (S/N3050, factory assembled). > When I transmit more than 12W(means hi power amp on) > within about 30min after mains power on, HI-TEMP alarm > occur and equipment is forced to set 5W. > > No problem at all when hi-power amp is through ( Po<12W ). > > Any idea? > Thanks in advance > 73, Atsu JE1TRV > > __ 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] K3 HI-TEMP ALARM
Hi I have same problem, when shack temperature is below 17 degrees Celcius When PA Temp is higher than 25 degrees C then power is OK. Jaakko OH1MA / K3 ser. 2952 Hi Elecrafters! I have problem on my K3/100 (S/N3050, factory assembled). When I transmit more than 12W(means hi power amp on) within about 30min after mains power on, HI-TEMP alarm occur and equipment is forced to set 5W. No problem at all when hi-power amp is through ( Po<12W ). Any idea?

Re: [Elecraft] K3 HI-TEMP ALARM
Atsu, did you check the fans ? Connect a power supply to your K3 and test the fans and KPAIO3 interface control as follows: - Press the POWER button to turn the K3 on. - Hold CONFIG to select the Configuration menu, then turn VFO B to KPA3. Normally, the display will indicate NOT INST (not installed). - Turn the VFO A knob to PAIO ON, then turn it further to PAIO TST. When moving between ON and TST, you should hear a relay click on the KPAIO3 board. If you don't, press the K3 POWER button to switch it off, then on again and retry the test. - Turn the VFO A knob on past TST to FN1, then FN2, FN3 and FN4. The fans should start turning at FN1 and increase speed as you continue to FN4. Turn the K3 off and disconnect the power supply. --- 73 de Thomas, DM7TN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of JE1TRV Sent: Sunday, January 10, 2010 3:14 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 HI-TEMP ALARM Hi Elecrafters!
