[NLRS] Deafness on 6M

[Bryan LaPlante]

Thanks to the group for helping me accurately measure my local noise issues,
it is better now.

However, I find my station is still plenty deaf.

The station -
6 M 3ele yagi, horizontal
TE systems brick
Timewave ANC4 noise canceller
Ten-Tec 1209 Transverter 6M->2M
2M rig Kenwood TR751a

at 50.750 MHz, I can pick up Channel 2 audio at S9+30+ if the Timewave is
off.
with it on, it's down to S9+20

I can't run the pre-amp on the TE brick - you just get overload.

Puzzles:
1) why do I get channel 2 at 50.75, when it should be at 59.xxx MHz?
partial answer - because I can also hear it on the HF rig at 9 MHz FM -
solid, but not showing much of an S-level.
Now, why on earth do I have it at 9MHz?

2) Is the reason I'm deaf because of local stations overloading me?

3) The Ten-Tec has only a 7 db or so NF - while other transverters have a 1
db NF.  Is this a big deal on 6M?

Solutions?
Do I need a cavity on 6M?
Tuned stub for 59MHz?
