Enhancement request - pan/zoom

[Have Blue]

Because I purchased my RF Explorer mostly just to 'play' with and learn more about RF, perhaps this wouldn't be as useful for those who are using it for actual analysis work, but I figured I'd toss the idea out anyhow.  Unless I'm testing a specific piece of equipment, I'm just using the RF-Ex as a 'visual radio scanner' to browse through the entire spectrum, looking for interesting peaks.  When I find something interesting, the only way to 'zoom in' on a peak is to go into the menu and manually adjust the frequency span (and hopefully guess close enough on how much span is needed).  Then, when I'm done, I need to 'zoom out' via the same method.

What I'd like to have is a way to adjust the frequency span by using the arrow keys.  Obviously, this would need a way to switch between 'pan' and 'zoom' modes, but I think this could be done by holding down a pair of arrow keys simultaneously.  Ideally, I'd love to have two more keys for 'zoom in' and 'zoom out' on the bottom (the keypad is just begging for a nice 3x3 button grid), but maybe that can happen in a future hardware revision...

Hi,

Your suggestion makes sense, and can be combined with an auto-tune feature I have in the TODO list, together with a few suggestions from another user who proposed a set of features like the ones you describe.

I will collect them all and populate in this thread so we can all contribute with ideas before final implementation takes place.

Thanks
Ariel

For reference, this was suggested by John sometime ago, and looks like a nice and simple approach:

I recently purchased the WSub1G RF-Explorer and love the functionality.  One suggestion would be to have the Left and Right arrows change the Span and keep the Center Freq. when in Center/Span mode, and pan (as it currently does) when in min max mode on the screen.  That way you can easily zoom in on a frequency instead of having to manually type in the numerical details you want to view.  If the span is between 10 and 100 then have the span adjust by 10.  If between 1 and 10, adjust by 1 ... etc.

Thanks,
    John

Ah, I never even thought of having it just switch depending on whether or not you have it in center/span or min/max - I love that idea even better!  Auto-tune sounds neat - can't wait to see the full list of proposed enhancements.

Yes I think this would be good and may be a natural feel as opposed to moving to the next 'window' of activity.
