ok, it's HOT in Longview, Tx; my garage hamshack is only slightly cooler than the great outdoors. I noticed at lunch, with the rig off, but powered, the fans were running... huh ?? maybe i'll just let ambient temps heat the thing, at least in summer ? I'm 'going green'...

    Dan: The temperature in your shack should not be an issue for the TCXO in your 6500, (or the OCXO in the 6700.) However, the fans running continuously with the unit turned off is unusual. ( I assume they are on "Low.") It could be either a software bug, or a hardware problem. Please disconnect all 12 Volt power from the unit, for say 10 seconds or so, then plug the 12 Volt power back in. If the fans now stay off, then some kind of shutdown sequence software bug. If they come back on without ever pressing the "On" button, then a hardware issue. Let us know which it is. We will then either add it to the software list, or have Tim move you to the Help/Service Desk. --- Graham / KE9H ==

    It shouldn't. The PC is just a thin client to connect to the radio server. The radio controls its own fans if DC power is applied to it.

    Dan: I'll ask Tim to open a help desk ticket. . It is not urgent and won't hurt anything (other than logging extra hours on the fans), but we should get your radio back and get the fan control resolved. --- Graham / KE9H. ==

    Dan, I am beginning to suspect that your high ambient temp is such that the radio requires that additional air flow to cool off the internal processors and remove latent heat from the transmitter being biased on RX.
