KXAT1 Alignment and Test Help I am not sure what I am suppose to see or do in the following steps:
Select 40 meters using KX1 BAND Switch (Done, I understand) Connect a 50-ohm Dummy Load (Done, I understand) Set the ATU parameter to CAL using the menu, (I think I am there. Pressed Menu, rotated the VFO knob to ATU, then press and hold MENU, rotate VFO knob to CAL.) I can hear the relays click when I go between CAL and TUN, in the ATU menu when I rotate the VFO knob. Is that how I select or bypass the ATU? I remained in the ATU CAL position while I adjusted the R1 and R2 as per the KXAT1 Manual Errata sheet Rev A-2. (The diagram was helpful, Thanks) Then I exited the ATU menu with the ATU still left in CAL, set up my DMM connected to a KX1 standoff and the REFL test point on the KXAT1 board. I entered the TUNE mode by pressing MENU and BAND at the same time. I then adjusted C9 for a null (0.7vdc) monitoring the DMM using the 2-3 VDC scale. I repeated the process using the DMMs 200-milli vdc scale I went back to the ATU menu and changed it back to TUN to support normal operations. My question really is, should I have left the ATU in the CAL position and exited to enter the TUNE mode? I measured the power out from the KX1 using the DL1 Dummy load test points. It shows a very solid 4 watts. I also installed the KXB30 meter module. During the alignment process I got a very positive peak from the 30A cap, but I really didnt see much of a response from the 30B.
