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

Tonight I achieved 2-axis control of my homebrew satellite system (so far, only one plane of antennas, but another may come soon). The elevation rotator is homebrew with Amazon motor and parts.?

Juan -- I checked, and the jumper appears to be present.? ?I was able to find it in the schematic also.? ?Thanks! Gordon

Ron -- I'm not a guru, but I've always been able to simply zip up the code on one of Ashhar's githubs, paste it into a place on a raspberry and get it to compile with something like ./build sbitx In

Where are they at with the order numbers on shipping the ZbitX's.??? I might need to be out of town and need to make allowances to have someone get my package for me. Thank you Jim KE0VVU

Thanks to David, who guided my thought is now fixed! but the zbitx now freezes a lot…. any suggestions?

Hi all, As I stated before, I bought a BitX40 at a hamfest a number of months ago, built by an unknown ham. I had to figure out what all the controls are and how they worked since none were labeled

Can I use a Raspberry Pi 4 with a fresh 32-bit OS install to build the binaries needed to run an zBitx? Is so, where are complete build instructions, including all the dependences required (sqlite,

Thanks a lot Gerry for the clarification. I had started a bit later in the hobby than most of you. There are a few younger hams in this region still getting hold of 807s and making linear amplifiers

Cannot guarantee it, but might be worth a try. Gotta fix those little problems. All radios have issues.

Took the family to DC/NYC for spring break so had the shop on hold for a bit. Saw your order this morning and got it in the mail on the way to work! Now trying to sort through all the groups.io

If zbitx/si5351v2.c is the correct place to look, then in lines 243, I see the variable drive_current being set to 2ma. But then that variable is being ignored, and the Si5351 is being configured in
