Ian KD8CEC is working on a new release of his CEC firmware for the uBITx that will be more modular in approach (picking up on John VK2ETA’s mods to Ian’s firmware), interface with a range of displays (I2C versions of the 1602 and 2004 displays as well as the display that comes with the Raduino). More importantly, however, this new version will enable the µBITx front-end of the receiver to be connected to an RTL-SDR USB device. The RTL-SDR device will draw on the HF receive sensitivity of the µBITx along with the front end bandpass filter and first IF roofing filter and associated IF stage amplifier (normally at 12MHz) to produce a quality SDR receiver (for just a few $s invested in the RTL-SDR tuner).
This version is available to download (1.071 Beta) from Ian’s website now.
