Hi

Did you remember to install the jumper wire in the ATU connector?

  Hi Guys,
  I've just completed my KX1 assembly through the receiver section and =
have a problem getting through the alignment. Hopefully someone will =
have some ideas with my description of the problem.
  1. I have very weak noise level and I know my earphones aren't optimum =
but I don't think they're the primary problem. I plan to get some better =
quality ear buds but I think I have something more serious right now.
  2. When I connect an external antenna, the noise level doesn't change =
noticeably and I certainly don't hear any frequency specific signals. I =
say specific because as my fingers get close to the tuning knob and =
U5/U6 specifically, I pick up some local broadcast station.
  3. When I set up my TS-450 to a 20 meter freq into a dummy load at =
minimum power and go key down, I can hear the carrier in the KX1 at the =
correct frequency but I don't hear the CW tone, just a broad carrier. I =
can attempt to peak the 20A & 20B trimmers and can indeed find a peak. I =
also then begin hearing 20 meters CW activity in the backgroud but as =
soon as I unkey the TS-450, the KX1 goes back quiet with very low noise =
level and no 20 meter background CW where there was some previously.
  Does anyone have any thoughts on this problem description? I assume I =
need to resolve this before continuing on with the xmtr.
  Thanks in advance.
