Bill, I found this info from an earlier posting by Ed in Alaska who was a beta tester.
On some of the early 2M models the printing on the metal shield was backwards to that shown in the manual. I made the mistake of installing my shield per the photo in the manual and got the shield on backwards which partially shorted the output transistor resulting in low RF output (0.3w vs 3.0w). I was one of the field testers so my unit was very early production. MY understanding is that the label issue was remedied in later units. To be absolutely sure the shield is on correctly you should visually examine the shield to see if the tiny cutout is over the output transistor (this is the one with a tab you secured with a black flat-head screw). You should be able to check it without removal of the shield. Another way to describe it is the cutout is along the side of the shield nearest the edge of the radio case. 73 David Anderson GM4JJJ > On 13 Jun 2015, at 06:51, BillP <b.bil...@gmail.com> wrote: > > KX-3 Serial number 2517 > Internal or external battery power, same condition. > HF SSB/CW/Digital operation is Fine > > No 2 meter RF output on any mode. > I've carefully followed the 2 meter module installation instructions and > firmware settings, loaded the latest software as of Friday AM (and again) and > cannot measure 2 meter RF at the SMA connector using verified coax and VHF > SWR bridge.
