Hi guys! Sorry it's been so long since I've updated. Believe me, I haven't forgotten. I've been hard at work! As you may know, the PortableSDR was selected as one of the 50 semi-finalists for the Hackaday Prize! Thanks everybody! Wish me luck!

The next round of judging is less than a month away so I am trying really hard to knock out the next revision of the PSDR. So far I've got dual capacitive touch keys (for morse code), battery charge controller, GPS, and the VNA/Antenna analyzer blocks. Even bigger microcontroller. Real time clock support, digital gain control. MicroSD slot.

Anti-aliasing filters are going in all over the place, built in speaker, mic, and an earphone connector that works with smartphone-style earphones/microphones will be included.

There are a few things that wont make it into this version (RF Amp, 144Mhz mixer) but for some things I am including a "shield" style place to plug in modules. I don't think I am going to get a new LCD in there this time. Also, PJRC's amazing work at speeding up the driver for the ILI9341 makes me think I may not need to switch to the parallel interface on the LCD (which takes A LOT OF PINS!)

I hope to have the schematic changes done in a few days and a PCB design as soon as possible after that (a week?). I'll keep you guys updated!

Great work, exhaustive documentation, progress looks better and better every time. Good luck to you, although I feel your design speaks for itself. And congratulations again!
