If it is the same 45 watt amplifier kit I bought a couple years ago, be aware that the INPUT of the amplifier needs to be EXTREMELY small - as in, milliwatts - or it will blow. Check the

There is a 45w amp kit sold rather cheap on ebay and aliexpress both. iam74@...> wrote:

Jorge: Note that you cannot directly substitute a IRF530 for a IRF510. That is because the input gate capacitance of the 510 is ~180 pF. and the gate capacitance of the 530 is ~620 pF. That means the

Use the MFJ to determine where the antenna is resonant. If the frequency is below 7.285 decrease the amount of coil and recheck. Conversely if it is resonate above 7.286 you will have to add coil.

Thanks for reporting Dave, Yes, it appears there is some variability between the BITX40 sets. Mine performs best at 4mA, yours may need another value. I suggest to use v1.08 as it allows you to

I was having a lot of difficulty with my bitx40, the audio would get louder, then softer. I have done a number of mods to the board, and added features to the point that it no longer worked right. I
