I agree that there are many people standing on Farhan's shoulders and he has certainly created/generated a huge interest in his uBIT-X design point..... key parameters being that the cost is being held low for a simple design to allow more people to try modifications if they want to ......AND he's allowing others to start small businesses and learn skills. I think the latter, in itself, is great.
Message counts of ~2000 per month definitely indicate a huge interest.
My point was that there are many steps in the progression from the uBIT-X that arrived in the mailbox, TO one that has slight modifications, TO more comprehensive AGC hardware, audio amps, etc, TO SWR indications, 4 line displays, more keyer features,
TO DSP and other SW defined modes, RPi, Teensy 3.5/3.6, large touch screens, etc ......you get the idea. Many options. The point is that you can take the path and get off at any step. I personally want to go as far as I feel makes sense to me (staying with the Nano or an Arduino based derivative and basically "Keeping It Simple") with a result that I think I can reach, and a Transceiver I will/can use. Some of the guys that want to Hack-to-the- Max ....more power to them but the number of followers will drop off pretty quickly and I for one will become a (maybe) drooler, not a follower.
