[GreenKeys] strange dovetron?

[William Wuttke]

I know I may be speaking heresy here, but the absolute best RTTY tuning indicator is the FlexRadio spectrum/waterfall. Mark and space tuning
indicators get placed exactly on the mark and space tones.

As far as the TUs go, if you are using an old analog radio, the Dovetron is a gem if you are receive only. Tweak the mark and space knobs on
virtually any set of tones as long as you can hear them. For two-way, you still need to tune the radio to the cross display, but it is just as easy
as a scope (at least to me).

An interesting tuning indicator is on the irl FSK-1000 - separate meters for mark and space. It actually works pretty well.
