Re: zBitx upgrading the firmware.
I forgot to add the question of what order should the updates be done in? ?Pico first?

Re: zBitx upgrading the firmware.
This is only the Pico firmware not the main Pi.

Re: zbitx hung-up on startup
Oh heck. You would have received a usb adapter to connect to regular usb devices. But you will need a mini hdmi to connect to a monitor.

Re: zbitx hung-up on startup
When you plug into the “CAT” port you are actually plugging into the microcontroller that runs the display stuff. ?The ports to the left are three ports to the Raspberry Pi main computer. ?I assume that you checked voltage and orientation on the batteries before connecting the radio. ?The DC power system on this radio may be a weak spot for operator error. ?

I was starting to update the WIKI here on groups.io but I am out of town for a few days. ?We need to have a single place for setup, upgrade, and FAQ like things. ?I do not know what HFsignals wants to do about that.

It is probably a bug. I will look into it. Can you file a bug on

I have also been a CW op for 40+ years and am unable to send anything accurately with the built in keyer. Will try with an external keyer later today.?

Tilman, tnx , I 'll update the RPI, I've already update the front panel.

Re: Zbitx external microphone recommendations
Interesting point, and probably relates to why there is a momentary transmit activation of the radio when plugging in a microphone. Gordon KX4Z
Hi there
I find it odd that the pinout of the microphone is different from all other radios having 3.5mm stereo connector.?
They "all" do have PTT to tip and ground and microphone to ring and ground. Means that I would need a adaptor to connect up my microphones? :-(

Hello Ashhar
?
I've received my zBITX this morning and have been listening on the bands in different modes. So far all seems to work as expected and it is fun to use this little rig.
But I'm lost by trying to send CW with the built in keyer. I'm not used to Lambic A after using Lambic B for 40+ years. When set to Lambic B you get a straight key. Is Lambic B not yet implemented or have I set something wrong? If not, will this be included in a firmware update?
Taking an additional external electronic with Lambic B keying half the size of the zBITX for portable use was not my plan...
?
Many thanks for this otherwise nice rig and for any info

Pierre,
The manual should be up on the site soon. We're working on revising it to make sure we document all the features on the zBitx.
Meanwhile, please have a look at from Farhan where he documents the functions of the radio.?

Re: Why? Why in bitx and ubitx is single balanced (2 diodes) mod/demod instead of double balanced??
It was just because, in a modulator, we didnt need to balance out the audio. The audio automatically gets filtered out by the crystal filter
Why in bitx and ubitx is single balanced (2 diodes) mod/demod instead of double balanced?? Just cost?
