Digital Frequency Counter Module Query

[Yorkie]

I've been watching that and pondering as it seems to be much more sensitive than the one I bought before.
Do the Buttons work through a series of Menues like the other one?

The second link that Lawrence gave clarifies the menus and is very helpful. 

The more I look at the spec, the handier the counter seems to be.

Quite a cheap addition to a homebrew radio, and if the sensitivity lives up to expectations, should make a nice little DFM for use on the bench.

I do have a 'PW Robin' (LF/HF/VHF) that I built many years ago which works well and goes up to 1 GHz, (designed by the late Mike Rowe of 'Sussex' valve-tester fame), but you can't have too much of a good thing!
