Re: New board is dead!
Carl,
That's because it boots into the RasPi OS. It has the sbitx info in the 2nd partition which is not readable by Windows.
Put it in the Pi and boot up the radio.

Re: #sBitx Sample Rate

Mark,
The bandwidth is limited by our crystal filter. I couldn't make it wider
than 25 KHz. If, instead, we had used phasing method, we could have
achieved a full 96 KHz spectrum display. I discarded

#sBitx Sample Rate
#sBitx
The sample rate appears to be 96 kHz, but the bandwidth is only 24 kHz. Shouldn't it be 48 kHz, half the sampling rate? Is this due to the overlap-discard processing?

Re: sBitx V2 SN #141 Spurious/Harmonic Measurements
Impressive that the harmonics are NOT a problem.? ?I don't remember ever being much worried by them on my DE, either.
I've seen those low low frequency spurious signals a lot.? ? I think changing

Re: sBitx V2 SN #141 Spurious/Harmonic Measurements
Gordon,
Here are two spectra for 80 and 10 meters.? 10 seems to be the worst, with both lower-than-set frequency spurs and a higher 3rd harmonic:
Based on the latest measurement, I may have a

Improving Dial Scale Linearity on a 15-10 meter BITX rig
Kind of old-school.? No rotary encoders or si5351s here.? Just L and C for the VFO.?

I would like to get a project enclosure and have a cable out the back for the microphone cable on the radio. Have 2 jacks, one for the electrict microphone and the other for PTT. It would be nice to

Re: FS Sbitx V2. (No Pi)
You can certainly use an amplified CB mic. I’ve done that with Heathkit vacuum tube transmitters successfully. However, it’s probably considerably cheaper to just use the element that I found

Rose, I’ve never tried the side tone for voice. I don’t know anything about that
If I crank the mic gain up as high as you were saying, I’ll have terrible distortion. With the stock Mike
