[HAM] buzzy 122

[Carl Mal]

As far as I know,  G1 and G2 are 180 out of phase, thereby balanced (mutually cancelling) when sharing common ground.

I expect this was used because of the  rf and emf rejection properties,  still in use today with microphone cables for example.

Do you mean you tested with headphones G1 & gnd, then G2 & gnd, -or- you clamped your headphones onto G and G?

When I 1st got my trek OBL-2, I tried clamping it onto G and G and got nasty humm.  When I connected to ONE of the Gs and chassis ground, it worked like it says on the box.

I don't expect the trek preamp would be any different than the old preamp in this regard.

I'm still a newb but starting to get it I hope, MC/SW/CC/Kon/JW/DW/KC/etc. will correct me if I'm wrong

I don't have a 122 but a 147 and am struggling to understand the differences.  

One day I might just post, 122/147 what's the Diff?
