[Elecraft] K3 Temperature Sensor Calibration
Consider re-calibrating the temperature sensors in your K3 before getting too alarmed about the readings. From the Owner's Manual: Front Panel Temperature Sensor Turn the K3 OFF. Allow about 15 minutes for the radio to cool to room temperature. Turn the K3 ON. Locate the CONFIG:FP TEMP menu entry. Adjust the parameter to match the reading of a room thermometer. Note: Deg. C = (deg. Fahrenheit - 32) * 0.555. PA Temperature Sensor Turn the K3 OFF. Allow about 15 minutes for the PA heat sink to cool to room temperature. Do not turn the K3 ON during this period. Turn the K3 ON. Locate the CONFIG:PA TEMP menu entry. Adjust the parameter to match the reading of a room thermometer. Note: Deg. C = (deg. Fahrenheit - 32) * 0.555. 73, Paul W8TM __ 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 temperature
Tom N0SS said What bothers me, a bit, is that my cooling fans seem to be running a LOT more frequently, and at higher speeds, than they did several firmware versions ago. My FP temperature rose from 18 C to 35 C in a three-hour test yesterday. I don't believe the fans came on but not sure as I can't hear them. When ever I look at them they are not running. The PA temp rose from 17 C to 25 C over the same period. (I may have transmitted a short SSB period, can't remember). So I am wondering at what temperature the fans come on and where that temperature is measured.

Re: [Elecraft] K3 temperature
The fans only come on in response to the PA temp sensor. In a future release they'll also come on if the FP temperature is excessive. But so far, I haven't seen any reports of excessive FP temperature -- they're all in the acceptable range. 73, Wayne N6KR On Jan 27, 2009, at 6:21 AM, Mike Scott wrote: My FP temperature rose from 18 C to 35 C in a three-hour test yesterday. --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 temperature
That's interesting. I would think that the PA shielding and top venting would make the fans pretty ineffective for cooling the FP. Or is the idea that if the FP is too warm, the PA is probably too warm as well, regardless of the reported PA temp? 73 -- Joe KB8AP On Jan 27, 2009, at 8:39 AM, wayne burdick wrote: The fans only come on in response to the PA temp sensor.

Re: [Elecraft] K3 temperature
Speaking of temperature - A week or two ago I complained about the fans continuously speeding up and slowing down during a contest. Since then I have set the fans to run continuously at low speed (config kpa3=fn1). The fans are almost inaudible at this speed, and I didn't hear them cycling up and down during the 160 cw or bartg sprint contests. The rigs were running only 50 watts though, driving high gain amps. The NAQP RTTY contest is coming up on Feb 28. That's a 100w RTTY contest. The rigs will get a workout there. I'll keep an eye on pa temp and fan speed. I did verify that with kpa3=fn1, the fans do speed up if pa temp rises.

Re: [Elecraft] K3 temperature
Since K3 #145 has had it's sub receiver the forward area of the right hand side panel seems to get a little warmer and I've assumed this is due to the sub rx or second dsp drawing extra through the 2 voltage regs bolted to that panel. Shows it's all working ok since the panel is the heatsink for those devices. I don't understand how you could suspect the sub rx of increasing the PA temperature if everything has been installed correctly. BTW: I took part in a local RTTY contest for the first time the other evening and was a little concerned about running full power despite reassurances here. Running about 95 watts for 90 contest minutes I kept an eye on the PA temperature and it never went above 46 deg; I put my hand over the back once or twice and the fans seemed to be running but only slowly. I'm now reassured. Stewart Rolfe, GW0ETF wayne burdick wrote: Since I fitted the second receiver, my K3 is running a whole lot warmer, even on receive with the sub receiver turned off. The aux DSP adds around 100 mA even when the sub receiver is turned off, as I recall, so some increase in temperature is normal. The KRX3 module itself adds nearly zero current when turned off, and I don't believe it could cause any increase in temperature since just due to its location above the RF board. When turned on, the KRX3 adds about 150-200 mA. -- View this message in context: http://n2.nabble.com/K3-temperature-tp2216250p2217060.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 temperature
Well... I must agree that, since the addition of the KRX3 in my K3, the internal temps HAVE risen on the order of about 10 deg. C overall... However, this is NOT anything I didn't expect... in fact, I seem to recall that Wayne even posted (somewhere) that KRX3 users would notice higher internal temps. What bothers me, a bit, is that my cooling fans seem to be running a LOT more frequently, and at higher speeds, than they did several firmware versions ago. I've mentioned this on the K3 Field Test reflector, but no one has risen to comment upon my observations. 73, Tom Hammond N0SS At 23:06 01/25/2009, Matt Zilmer wrote: Hi Barry, I installed the KRX3 in #24 here last week. My experience with temps is different from yours. Ambient temp: 22C FP temp: 23C PA temp 34C (this is right now - in the middle of NA winter) Chassis exterior doesn't have temps any different from before the KRX3 went in here. At least not so far. This was after the K3 had been sitting on for most of the afternoon. Now, it's possible that your ambient temp is different, given that you are set right in the middle of Summer there. However, I recorded FP and PA temps no higher than 36/48 here last summer. This was due to the fact that I was running a lot of high duty cycle PSK31 QSO's at the time. The ambient open-house temp was 35C, which is a little warm. And believe me, the fans were running! We were open-house because of a power outage, and with solar power the only inconvience was sweat. You might want to look at how your cables are dressed, esp. the one at the back from ANT receptacle to the KRX3. If your fans can't get started, this might explain the high-temp problem. If the cable is laying across the fan(s) Also - make sure the KRX3 shield box isn't contacting anything on the RF Board. Check your DC power supply's metering to see if it pulls appreciably more current with the KRX3 installed. It seems unlikely that the KRX3 is the problem.

Hi Barry, I have noticed the same. Here also, the FP temp settles at roughly 36C, receive only. This is much warmer than before I fitted the KRX3. Ambient temperature here is about 20C.

However, I've never seen an FP temperature of higher than 41C, so if you're seeing 44C, you might check your FP temp calibration. Even 44C is very unlikely to be a problem. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

To put this into context 37C is very warm, it isn't. I used to do elevated temperature dynamic burn-in on fiber optic RS-232 modules at 50C in a precision temperature controlled oven.

Re: [Elecraft] K3 - Temperature Specifications
Hi Stewart, I have a K3/100 + KRX3/KXV3/KAT3. In RX/stby it runs 1.01 A @ 14V according to the K3 display. I agree that the temperature is quite high. With about 26.7 degC in the shack I read FP 41 degC and PA 36 degC after 1 hr stby. I guess the two DSPs are generating quite some heat + the FP lamps. I have the display at its lowest brightness (2). When I make a QSO with a couple of transmissions the PA temp rises to about 41~43 degC. The fans are very efficient in cooling down the PA quickly afterwards. Comparing the feel temp of the K3 case with other rigs (FT1000MP and IC736), give me the impression that all this is not excessive. BTW. I wonder what current exactly is measured and displayed (could not find a clue in the owner's manual). 14 W in standby with AF volume at normal level, with all my options, seems a bit low. I would rather expect something in the range of 50 to 100W. -- Enno, PF5X Stewart Baker wrote: Thanks Gary (and others), I think that since fitting the 2nd RX the unit gets quite a bit warmer.
