Woody KZ4AK tell us that he is very happy with his µBITx.
He has completed many of the board mods, added RX amp/attn/agc, changed and added to the RX audio chain, added forward and reverse power meter & S meter, VOX, sound card interface, and fan.
Woody says the TX power is still about 6db down from what he expected and he plans to address that later. He is achieving about 3 watts out on 80m SSB which is a bit of a challenge, but it works! On the other hand he is getting near 10 watts on 30M FT8.
Most of the details are in two ZIP files that can be downloaded. The uBITX is at the top of the list.
