The uBITX comes with a 2 line display and an Arduino CPU. (not shown). I am designing a 5″ display, Cortex-A8 (minimum) CPU with the Si5351A Synthesizer chip, and will be writing the FW for it. Also, will be designing a circuit to tap off the IF and provide a band scope/waterfall on the 5″ display. In addition, will be designing an audio circuit so that the radio can be plugged into a computer to run digital modes. (Maybe include a decoder in the FW?). Maybe just put a bluetooth module and write a control protocol, and build an iOS app/macOS App to run the radio. Now, this sounds ambitious, and it is, but I really want to build the radio they way I want to. I will probably add a remote facility to control it via a network, or better the web (OpenWebRX?). I am hoping to be similar to the display in the second picture. If it turns out well, it could become a side business. The display will look somewhat like this:
Apparently, it arrived a couple of days ago, and was behind a planter on the front porch. (Thanks DHL).
The main board is very nicely done.
I got notified the other day that my uBitx is shipping from India. I cannot wait to try this radio. Meanwhile, I have been working on a better display system. I plan on re-doing the Raduino in my own way. New main display board using a 2.8” display, and maybe a more powerful Arduino, or even switching to a different CPU (cortex-m0?). I am working out the circuit as we speak (as well as working on stuff I do for work, so the new front panel console will be done in my own time). I have even considered putting in a 4”-5” LCD and adding a landscape to the receiver. Anyways, now a days it is great to be a home brewer and the toolset to make your own stuff, while expensive, is powerful.
Well, I have received a SDRPlay RSP-2Pro and I love it. Such a beautiful SDR. The folks at SDRPlay really did a nice job on this thing. I run SDRUno with it on a (ick) Windows 10 installation in BootCamp on my MacBook Pro and it is a nice combo. (Hey SDRPlay, you should have me port SDRUno to macOS!). What I like about the RSP-2pro is the metal case, and that it has 3 antenna inputs. a Hi-Z, a standard SMA antenna connection, and a bias-t SMA antenna connection (to power those LNAs, etc). The thing really shines, and compared to the RSP-1, the difference is amazing. Another SDR for the shack!
