Yeah, it’s that extra 5% when you’re blind though. …

I felt exactly the same way when Al suggested using TS instead of a menu system. Now, I like it. Keep in mind you rarely actually "use" the TS system, with probably 95% of the time you're only using the Tuning and ALS encoders. Indeed, once you do the setup to set the "factory defaults" to your preferences (e.g., DSP filters, WPM, sidetone frequency and volume, equalizer, etc.), there's little need to use the TS system. Think about it.

Sounds great, except, and understanding I’m in a minority of 1 here, the touch screen. I’d love this tied to a menu if needed plus a 4X4 keypad or such. …

If we went to a screen that small, I think we'd drop the touch screen feature and do complete menu system. The costs aren't cheap compared to those display sizes (e.g., > $10 versus $34), but 5" at 800x480 is nothing to throw rocks at and is easier on the eyes for us old people. Also, quite a few have adopted the Nextion display and they cost twice as much as ours and are about half the size. Also, we give you an experimenters platform with a dozen empty pins and idle resources to play with (see feature set below). Also, we have a pretty robust feature set:

5” or 7” TFT Touch Screen 800x480 TFT Color Display
Dual VFO
S Meter
Real Time Clock (add optional battery)
50 CW Preset Messages, selectable at runtime
Touch Screen Band Selection
Touch Screen Buttons for function selection and control
Dual Encoders: Frequency Tuning, ALS Tuning, Program Input
Frequency Tuning:
ALS Tuning--ALS Tuning: Special tuning using the second encoder. If the
frequency increment is set to 1KHz, ALS Tuning sets the second
encoder to one-tenth the increment of the primary tuning rate. This
allows for rapid tuning to an approximate frequency using the main
encoder and then using ALS Tuning with the second encoder to fine
tune the signal. Once you use it, you'll wonder how you lived without it.
Filter Selection:
CW presets (3dB bandwidth): 150 Hz, 300 Hz, 400 Hz, 600 Hz
SSB presets (3dB bandwidth): 1500 Hz, 1800 Hz , 2200 Hz, 3000 Hz
EEprom storage of user preferences and CW code presets
3 external hardware buttons for CW code messages (e.g., contest exchanges)
Based on Teensy 3.6 Microcontroller with Audio Shield
Hardware AGC using IF take-off
Mic Compressor with adjustable threshold
Mic 8-band equalization
Receive Audio Filter
48 dB/octave (8 pole equivalent DSP filters)
2 Variable bandwidth filters – user-defined knee frequencies with Rotary Encoder control
Audio AGC with adjustable threshold
Variable Notch filter, encoder adjustable, use specified Q
CW code to Text converter
Code Practice Oscillator Mode
About a dozen I/O pins to play with plus 800K of free flash memory, 200K of free SRAM,
all clocked at 180MHz

Finally, this is Rel. 1.0 of the software. We think we can do some pretty clever stuff with Rel. 2.0. You can see these board in the video here:
JackAl uBITX Add-on

JackAl uBITX Add-on
This is a preview of the up-coming uBITX add-on board. Centered around a high-resolution touch screen TFT displa...

We also think the system is flexible enough to adapt to other inexpensive rigs. Al and I plan to experiment with this after JackAl is released.

can this be adapted to small tft displays? the cost of going from a 2.4 inch to this display is quite high.

If you can run the Arduino IDE, I don't see why not. The software is all on the board. If you can't run the IDE, go to a school lab, borrow a Windows machine, ciompile/upload, take home and plug in...done!

Jack and Al,
I concur. I also would prefer a “all in one place” maxi purchase. Many of us have Macs and cannot use Ian’s utility program. Will we also be able to utilize the Jackal? 73 Mike KF6KXG
