When I introduced CTR2 last year I included basic control features for Flex radios. In a nutshell, you could control the A slice and a few other basic features of the radio. The idea was to provide enough utility to allow you to use CTR2 to control your Flex without SmartSDR running.

When I ported the code from CTR2 to create CTR2-Mini those same features came over to the Mini. Several hams wondered if it would be possible to control more than just slice A so I got to work. I’m happy to report that you can now connect to and control any slice on your Flex with your Mini. You can also create new slices and/or panadapters on the fly. You can connect more than one Mini to your Flex radio with each controlling its own slice. If you’re not running SmartSDR the first Mini to connect becomes the “GUI Client”. Other Minis will connect as “Non-GUI Clients”. Simply push the [A] button (Tx Enable) on the Mini whose slice you want to make active. If another Mini was active, it will switch to inactive mode.

As of v1.02.01 the Mini now supports CW keying over WiFi. This means that you can connect a straight key or set of paddles to your Mini, enable network keying, then connect the Mini to your Flex over WiFi and have a real CW QSO. You can run SmartSDR on your iPad or iPhone if you want the full panadapter experience like Stefan, VA3AR, does in the photo below (photo courtesy of VA3AR), otherwise just use Mini to run your radio as a POR (Plain Old Radio).

I demonstrate most of the new features in this YouTube video. Click here to watch it.

Flex Only Shack?

If you run a Flex-only shack you don’t need a physical interface between your Mini and your radio. Both PTT and KEY outputs on the Mini can be mapped to use the network connection instead of the physical PTT and KEY outputs from the Radio I/O module. If you don’t want the Radio I/O module included in your order just indicate that on the order form and I’ll deduct the cost of that module from your order.
