A list of mods from BITX Hacks I build in my BitX40.
BitX40 mod #1
Although I didn't think that I needed it, but having my first QSO with Gerald PA3GEG (just 5 clicks away from me), I realised that a RF-Gain control is a must. So the first mod I added to my BITX40 is the "ND6T's RF Gain Control". I didn't use the tombstone method, because the mod can also be done by removing R15 and connect a 10K ohm variable resistor in serie with a 10 ohm resistor to the now open pats of R15. Easy piecy and works like a charm.
BitX40 mod #2
Working on that.
