Hi Lyle, Having the HI RFI detection and warning message is great. If I ever saw it, my first reaction would be to turn the K3 off. Does turning the rig off provide any more protection from the high RF levels than what the built-in protection circuits do when operating?
The next thing I would do is look in the manual index for "HI RFI". In rev D2 of the manual, there's no index entry for that. (There is an entry for "RFI detection", but not for "HI RFI"). Given that immediate action should be taken to prevent damage to the rig, it might be good to have an index entry for the message for quick access. 73 -- Joe KB8AP On Jun 30, 2009, at 8:26 AM, Lyle Johnson wrote: > Hello Lee! > > The HI RFI message is informing you that there is a problem in the > station which is resulting in potentially damaging levels of RF being > applied to the K3 receiver. > > This could be due to another transmitting radio's antenna(s) being too > close, someone accidentally connecting their transmitter to the K3's > feedline and keying that transmitter, or any number of other > possibilities. > > It does not necessarily mean "The K3 front end is damaged and needs to > be repaired."
