[Elecraft] K3 Front Panel

[Mike Greenway]

I just received a new K3 S/N 7604.  I am noticing the front panel is running very warm.  It has the second receiver installed so that might be a reason.  I have another K3 without the second receiver and it is very cool with a reading of 36 C for the front panel but the new one is showing 61 C.  The static PA temps compare.  Is this a normal range for the K3 with a second RX? The radio are the same other than the 2 nd RX.  Maybe some input from other users with the second RX.  73 Mike K4PI
