I just received my KX2 and really like it. I have the ATU and battery
installed. Receive works fine, but I cannot transmit. When I press PTT
I get several beeps and in some cases the radio shuts off. Sometimes I
get a Hi CUR message. Here is some data:
7.213 MHz, Voltage 11.7, Power set at 8 watts. When I press ATU
to tune the tuner works hard and displays 25.4 - 1 while trying to tune
and never changes. Is this telling me the SWR is 25.4:1? The antenna
SWR checked at the BNC connector on the antenna at the radio with an MFJ
259B is 1.3:1
7.285 MHz, Voltage 11.7, Power 8 watts, SWR checked with MFJ 259B is
2.0:1. Same result when I press ATU.
When I bypass the ATU I still get the same result except that I do not
see the 25.4 - 1 display.
Also, same result on all other bands. I installed the side panels
before I tried to transmit. I thought maybe I had a bad antenna
connection. A check with an ohm meter shows a good connection between
the BNC connector and the antenna connection on the ATU board.
I checked the connector from the ATU to the RF board and it seems to be
mated properly. I tried transmitting into a 50 ohm dummy load with the
same result. I made a jumper cable with a BNC connect on it and
connected it to the ATU bypassing the installed BNC connector - same result.
SN is 463, just installed firmware 2.66. Did not try to transmit before
upgrading to 2.66 or installing the side panels. Seems to me I have a
bad antenna connection somewhere. Does this make sense?
Any help will be appreciated.
