My batch2 ZbitX shipped today and delivery is expected friday according to DHL. -Dean

Ron, I have that same problem, in fact I would say every zBitx owner is having this problem. There are some on this group that think this might be the SPI serial interface updating the display and

If you have 807s and power transformers available then use what you have.? Tubes are almost unavailable here and unused.? I couldn't even give away a few 2E26 tubes - nobody wanted them. Gerry

Evan, Thanks for the advice. Jeff returned from vacation and I placed an order on his site for the board kit. Very quick response and Jeff shipped an assembled board as an upgrade. Outstanding

The exact same thing happens to me. I'm a Morse code operator, and proper CW operation is crucial to me. Since I'm not very good at updating firmware and modifying the radio, I don't mind waiting a

I think this effect is due to its very small size. Probably shielding would eliminate the problem. This could be aluminum or copper foil, which is insulated on both sides. Short circuits should be

I hear a pulsing noise from my zBitx speaker, even with a dummy load connected instead of an antenna, and both the audio volume and IF gain turn down. Seems to pulse or hum 3 to 5 times per second. Is

The reason that the zBitx is not supplied with a battery is because of shipping restrictions on lithium batteries. The shipping time would be much longer if the battery were included because it would

The dependencies are in install.txt on github. The run will not happen without hardware because it will be missing the components connected to the GPIO pins for proper operation. The hardware is

That's modem_next_sample in the above. You can read online about Flex cw keying issues in a $4500 radio. I have a Peaberry V2.?? David the designer actually wrote a little windows driver program

Executive summary:?? The pin change interrupts could/should implement Dit latch and Dah latch that should be processed before reading the state of the keys with key_poll. In modem.c we have

Gordon, Just in case test the rx on the lower portion of the 70cm xverter band. Closer to 432mhz. The ones I have are not very broad banded. So maybe you have to adjust the transverter bandpass

I don't notice much of a difference in the audio, but when the switch is up, which I'm assuming is the fast position, the meter needle drops faster than it does in the down position. I may remove the

What? is the password for the*zBitx *Pi OS? When I try to install a .deb file, I am asked for a 'user name' which is filled in as 'Pi'. What is the password I should use? Thank you.? Don in

OK, thanks. Yes, there is an S-meter installed in the front panel. I'll give a more careful listen to see if there's an audio difference between the switch positions. So far I can't tell much of a
