I am seriously considering adding two new streams.

To help people adjust TUs. for 170 shift. Active filters

drift and must be re-aligned every year or two.

One would be a steady 2125 cycle tone.

The other would be a steady 2295 cycle tone.

How do you Greenkeyers feel about this possible service?

It may be a bit of expense and trouble and I don't want

to do it if nobody cares.
