[Elecraft] T1 on KAT2

[Wilton, Paul]

I have just got the stage of setting the bridge null adjustment (C55) and am only getting HI on the display.  Putting a DVM probe on U1 Pin 4 shows that the REFL voltage goes between 2.4 and 6.4v as C55 is adjusted.  I have checked out the components around the SWR bridge (all ok) and have checked for bad soldering around T1 - all ok.  However, I notice that I have installed T1 "upside down" ie leads 2 and 4 come from the underside of the toroid and 1 and 3 come from the topside.  I suspect that this is cause of my problems.  However, before I dismantle T1, would anyone like to confirm that this indeed is my problem.

#2546 is otherwise going well.  SSB board is in and working ok.  Need to do the flattening mod and to work out why the current readings are low, otherwise all ok.  Once the ATU is done, aim to have my first HF QSO.  Then it will be a fight with my 8 year old son (M3DPW) as to who gets to use it!
