Nick VK4PP is working on a nice little add-on board for the µBitx with the following mods incorporated:
- 200hz CW Filter
- Mic Preamp (SMM2167 Module)
- VK3YE LED AGC
- LPF section (Dual relay per filter)
- POP fix for earlier v3 boards, and
- High Pass Filter on RX for BCI option.
Nick is designing it for use with through hole components with the exception of the 100uh inductors underneath the board, which will need to be 1206 Surface Mount devices. At this stage he is hoping to provide the board at $5 each plus post (VK-$1, DX-$3).
