Hi,
I received my KX3 one week ago and had some fun yesterday with it and an
end-fed wire antenna roughly 20 mtrs long. The ATU worked great on getting
the SWR down to 1:1 (not on 160) but there was an issue that concerns me:
while transmitting, the ATU icon in the display went flashing and the SWR
changed. I'm not sure if the relays clicked or not (have been using
earphones) but I think so. At another instance, I saw the "HI CURR" warning
in the display and heard a relay clicking (I was only running 4W and the
power supply was a 25 A, 13.7 V linear). I think the tuner suddenly went
into a kind of bypass mode at both instances.
There is a video on youtube showing exactly what happened to me.
Is anyone else here experiencing this? Is it related to antenna impedance or
poor ground? Have been using the same wire with a K2 and its tuner and never
noticed something like this.
