As someone that cut their teeth is the '70s with K&R C the biggest thing I see is poor programming not poor programming languages. I also grew up in systems where resources are scarce and adding

If the problem is feedback from the RF portion of the AGC board back to the AF input, wouldn't a ferrite bead on the Audio input at the AGC board accomplish the same thing without attenuating the

I have this happen, but typically with poor SWR. That would make sense if it is an EMI issue, wouldn't it?

Kees, I tried the clip on beads and if anything it made matters worse- applied to the audio cable. Perhaps multiple turns on a more perfect mixture may help but in reality adding that additional

Did you add the ferrite bead on only the Audio line (not the ground) and was it #43 material ? That's what I would try. But if adding 10nF-15nF to ground which is about 7K at audio frequencies is OK,

Writing that in plain ansi C is just more error prone work than it needs to be. What is your suggestion to fix that? There are elements of C++ that I don't like and tend to be misused (e.g., multiple

Howdy, I am seeking someone close to Atlanta, GA that has a working Bitx-40 "Kit" the one that you just do the final wiring and put the "kit" in a enclosure. My "kit" receives great but does not

Forgot to ask. Did you connect the capacitor across the connector end to ground of C1 or the 2N3904 Base end of C1 to ground ? 73 Kees K5BCQ

FWIW, I soldered the cap across the audio input pins on the underside of the board. I didn't have an SMD so it's just a plain old leaded part...I'm not even sure what technology it is (it's blue),

Ian : I did as you suggested within the uBITX Manager : - Enabled Adjust CW Frequency - Shift Display Frequency on CWL, CWU Mode I encoded and wrote to the uBITX and then reset and I see no

I did it exactly as Mark did and I'm using Kees' PCB. John KC9OJV

I just uploaded 4 files for the Nextion 3.2 display. They are for the basic and enhanced to work with Dr Ian Lee's CEC 1.094 firmware. I am starting to work on the 3.5 display next. I would appreciate

I ordered mine towards the end of April, there was stock showing at the time of order but this soon changed. I had several email exchanges with Sunil, over the course of my wait, with a final

Len Steel, Is your enclosure metal or plastic? Just one more possible cause.
