Pitft 480x320

[ac6y]

Hi András,
I just discovered qtcsdr and was very excited to try it out for a totally-portable RPi3-based, battery-powered sdr setup with the 3.5" Adafruit PiTFT

I didn't have any idea what I was doing (I haven't programmed qt before), but I found designer-qt4 and took a stab at squeezing your ui down to 480x320. It actually worked, so I'm passing it along in case it's of interest. I don't know what the right way to make an alternative ui like this into a proper option, perhaps at build-time or even as a cli option - what do you think? So this PR isn't really ready to be merged right now - it is just meant to pass along the alternate mainwindow.ui file.

Having the waterfall float behind the buttons was totally an accident, but looks pretty neat on the tiny screen. :)

Thanks for putting qtcsdr out there - I'm very excited to discover it and find that it works so nicely on the Pi3... it's nice and lightweight and looks easily extensible the way you're tying together the dsp chain via the shell. I'm hoping eventually to develop (or find) a "Universal Software Radio Physical Interface" - perhaps RPi-based, with real knobs and switches (maybe using teensy), that could easily be upgraded with anything from an RTL-SDR to an Ettus radio (and also have the main compute board easily upgradeable too). RPi3 and QTCSDR seem like a great platform to base a project like this on!

Cheers,
Michael, AC6Y

Hi Michael,

I agree too that qtcsdr is a really nice development! I already shown my transceiver concept to my firend András, athough we are booth on lack of time nowadays to finish that.
Here I'm sharing my idea of a RPi based transceiver:

Cool!

Thanks! I'll look for a way to integrate it into qtcsdr.

73!

Great! I am running the software on raspberry 2, it is very speedy and low cpu load! Very fine. If need I will try to contribute. Best 73 de IK8YFW.

@gcallipo Great! Thanks!
