I'm Chris.
Yes. Thanks for the diagram Chris, it explains things a lot more more simply - "a picture is worth a thousand words"!

Just to update this I replaced the Dale 100k resistor with 220k AN Tantalum's.
Result, knocked off 7-9 db which dropped the noise floor very nicely. Definite improvement overall, although I concede there are better ways to lower gain but they are currently slightly beyond my abilities.
Appreciate everyone's views.

How do you calculate these values? I have found a T Attenuator calculator here https://www.leleivre.com/rf_tpad.html
