[Elecraft] Normal KPA500 behavior?

[Mike Walsh]

Hi,

My KPA500 does a couple of things that seem a bit odd.  Other KPA owners - do your KPAs also do the following?

1)  When I transmit a 500 watt carrier while displaying TEMP the displayed temperature drops 5 degrees C.  When I release the key the temperature goes immediately back to the real value.  Lower transmit power levels cause a correspondingly lower drop in displayed temp.  This behavior causes the temp display to bounce around while transmitting CW.

2) When I power down my KPA the fan turns on (as it should) and then the right most POWER LED flashes on an off quickly.  Is that LED flash normal?

Thanks and 73,
