Re: suggestions for a graphics display
Farhan good thinking. However, I would suggest not to use the small displays as it will be difficult for most of the old timers to read. Balance the size with cost Thanks and regards Lawrence

Vic, I understand that the specifics are for the Bitx40, however some of the comments were that it was used on commercial rigs to protect receiver front ends.? Would be interested in the reason it

Is there anyone in Maine, USA that would be interested in a couple unassembled BITX40s? I have two kits. I was about to assemble but have decided not to. I'll make a local person a really good

Re: BITX 40 #bitx40 #bitx40help
Another 'gotcha' on the Bitx40 is the LM386 - it really doesn't like pin 3 direct to earth (Volume pot wiper)! The track to the socket runs alongside the IC, so it's not a huge task to cut a break,

Re: BITX 40 #bitx40 #bitx40help
Oh Lordy! Why the -12V??? Make that line 0V (GND)! The regulator on the Raduino is 5V out, and needs a minimum of 1.5V extra input. At its max current, that means 1.5Watts or so to dissipate, which

Re: bitx v3 rx linearity?
Check the biasing of the transistors to verify that they are in the linear range.
By Gordon Gibby <ggibby@...> · #65446 ·
Re: bitx v3 rx linearity?
Probably due to biasing of Q70. Try change R50 to 180K and/or R51 to 2.2K, that should change the Q70 collector voltage and give you more amplitude before clipping. Raj
