Hi,
I worked a little bit of the SSB contest this weekend. I noticed last
night I received the HI CUR warning a couple of times. The antenna is a
40m delta loop. I have checked the SWR and it never gets above 2:1 on
the entire band. I also use the internal ATU to get it down to 1:1 when
I'm transmitting. I am using a heil goldline with a HC5 cartridge for
the mic and the mic gain was set to 3. I have never had the HI CUR
warning occur while operating CW only in SSB. I looked up HI CUR in the
manual and it says that it's usually to do with the radio trying to
drive the finals at a higher output than what they are rated. I can
connect a dummy load and set the radio to 10 watts then hold down the
TUNE + DISPLAY buttons to put the radio in tune mode bypassing the ATU
and the radio is putting out the correct amount of power which leads me
to believe that the issue has something to do with the mic. Do you
think I have the mic gain set too high? I have since backed it down to 1
and it hasn't done it since but it wasn't doing it everytime when it was
set to 3 so I really don't know if that fixed it or not. Is there
anyone else who uses a Heil Goldline with their K2? Am I even going
down the right path troubleshooting wise? Or should I be looking at
something else?
