Front panel temperature
Locked
 
|
I raised the issue some time ago of my K3 front panel temperature being much
higher after installing the KRX3. At that time Wayne or Eric indicated they would look into a new function of controlling the fan by the front panel temperature as well as by the PA temperature. Any progress or further thoughts on this guys ?

I have observed the same with my K3. Although I have never calibrated my FP temperature sensor, it was usually hovering around 25 Celsius before installing KRX3. With the subreceiver installed, the FP sensor is now pushing 45C and I can feel top of the radio's front panel being quite warm to the touch. I also had another problem with my K3 (# 789) related to temperature. This one is actually related to K3's ability to handle cold environment. I was operating some of CQ 160 contests this winter from a place with no available heating. The temparature in the shack was around 7 degrees at the begining of the contest. The cold environment caused the K3 to randomly go into TX mode while spinning the VFO knob. The faster I would spin the knob, the RX/TX ratio would increase. I also had to turn off radio pooling from within contest logger (Win-Test) which would also cause K3 to go into Transmit every time PC pools the radio. If I remember correctly, CW keying via RS232 wouldn't work either. Having the temparature in the shack risen above approx 15c , K3 would start working normally. I wonder if anyone else observed this problem? 73, Nick ve3ey ----- Original Message ---- From: Barry Simpson <[hidden email]> To: [hidden email] Sent: Friday, March 27, 2009 6:14:23 AM Subject: [Elecraft] Front panel temperature I raised the issue some time ago of my K3 front panel temperature being much higher after installing the KRX3.

I think mine is up around 35 to 40 C and no KRX3 yet - I did calibrate
it and the KAT3 temp too. -- Power is no substitute for Skill. On 27 Mar 2009, at 11:22, Nick Lekic wrote: > > I have observed the same with my K3.
