Amazing!

Re: Reverse polarity protection on the sBitx? #sBitx #sBITX_v3
Reverse diode and a fuse is all I use on any of my projects. Total cost about $0.50. Voltage drop equal zero.

I also use the fet method, not as simple as a diode, but voltage drop way lesd [email protected]> wrote:

Re: Reverse polarity protection on the sBitx? #sBitx #sBITX_v3
I use Powerpoles for battery and PSU connections.? I also use KC9ON's FET-based devices in place of diodes.? They're good for up to 50 V and 7

Re: Sbitx and ad831 mixer
Farhan, Later I would like learn more about harmonic mixing. What I think I would do is to setup the bandpass filters for 10m, 6m, 4m and 2m. If fm is added later, it will be fun to operate on those

Re: Sbitx and ad831 mixer
Peter, This the normal sbitx software with audio injector card and si5351. Have two ad831 mixers and a 10.7mhz 30khz crystal filter. To rx clock 2 goes to first mixer and bfo goes to 2nd mixer. Sound

Re: Sbitx and ad831 mixer
This is a nice setup, can you explain it in a bit more detail, what frequencies are you running on each mixer, I assume the second one is a fixed frequency, and are you pushing the output into

Re: Sbitx and ad831 mixer
Farhan, This is a video of a ssb tx test and how it looks on sbitx v1 spectrum. For mic bias I used 10k resistor to 5v and 4.7uf capacitor. No mic

Re: Sbitx and ad831 mixer
With the AD831 mixer, you should be able to use 3rd harmonic mixing and go upto 435 Mhz [email protected]> wrote:

Re: Sbitx and ad831 mixer
Farhan, No band pass filter in place yet. Just wanted to see if it was generating rf.? Need to decide which bands to include since the need to filter per band. Juan WP3DN

Re: Sbitx and ad831 mixer
Incredible! Have you tried SSB? That is the proof of overall linearity. What is your bandpass filter? [email protected]> wrote:

Re: Sbitx and ad831 mixer
Tx works!!!! Did a little board to swap the clocks and another board to switch rx/transmit audio and tx/receive audio. Very low power but enough to listen on a handheld radio!!! Juan WP3DN

As often happens on the group, we seem to have several threads running simultaneously. I believe Bill was responding to my post about the prospective board and semi-kit buyer list that was in

Re: Production zBitx #zbitx
Too bad. It would be an instant success. I can only think HF Signals cannot afford the little investment required (which is not so comforting...)

Hi Shawn - the 64 bit distribution is all volunteer / user contributed.? You sound like you know what you are doing - I'm sure you will be more than wellcome to jump in and contribute. And Farhan is

Re: AM on sBITX?
I believe Farhan has also included this in the farhandev branch of the 32bit project.

The code base is the same. Checkout the.farhandev branch of sbitx repository [email protected]> wrote:
