Hi Glenn, My bitx40 originally had loud clicks whilst tuning is changing, decoupling the supply to the Raduino board helped a lot, it does not totally eliminate the clicking, but with the antenna

AF6TC tonight with analog BitX40. TX to CA. Always a thrill but the ears on the other end are a very important part. 72, Bob KI0G

very neat gian, which software do you use? i have been using kicad and the schematic symbols are 'horrendous' as they say back home in london. - f [email protected]> wrote:

Guys- Here are pix's of my BITX40 fired up today in Receive for testing. #1 I have the tuning clicks- so I will be debugging that. #2 shown in the pictures is my test of calibration which was not

In a pinch you can solder them, then I didn't crimp the wings that normally crimp on the wire, they aren't that tall so they'll fit in the housing and if it's a good solder joint there's no reason to

The prescaler and especially the AD8703 stuffing options are admittedly a bit over the top. ?The audio and RF signal generators and the RF probe would likely cost pennies, it's all R's and C's and a

Hi I see that Adafruit sells the PA-09 crimper. If you watch either Adafruit's Ask An Engineer or Show and Tell shows, they will show a 10% discount code. These shows are live on YouTube, Show and

Hi Jerry: Rolling these features into the BITX40 (hopefully) is unnecessary. That said, I think a (non-integrated) tool with these features would be useful for almost everyone; BITX40 or not.? I

I'd like to see some sort of RF probe built into the main board of the Bitx40 on any new PCB rev. ?At least pads and traces laid out for it, to optionally be stuffed with parts obtained by the user.

Hi Don, In addition to the other very valuable insights and suggestions you've received, for the specific problem of the carrier behaving as an "AM transmitter", I'd suggest you check the balanced
