Hello everyone,
During the alignment of the Top Band option of my K2 I did a stupid thing
and connected the dummy load to the wrong antenna connector. I used the tune
button and tried to align the filters to set the TX power using the power level
set to 2 watts. I got a high current warning on the display and then no power
out. So it looks like I have damaged the PA by transmitting into no load. The
net result is that I have no TX on all bands. There was no smoke, no excessive
heat and no visual damage to components. The K2 ATU option displays 0.1:1 when
I hit the tune button (incidently I thought the K2 should display power out
when the tune button is pressed) and the Motorola test set I use indicates 0
power out. RX seems fine.
I can only work on the rig at the weekends and there is no friendly
component shop handy where I live. Clearly I will need to replace something. So
I was thinking of ordering the components which might have failed by mail order
and what I dont use will go into my spares store. Any ideas what I should order
and or where the fault might lie....
Thanks in advance,
Steve
