sBitx or zBitx: Analyzing the FT8 messages in my application
I'm interested in analyzing the received FT8 messages in a software (e.g., a Python script) to detect messages from DX entities which I'm especially interested in. In case of sBitx, it can be a script running on the radio itself. In case of zBitx it can be a script running on a connected laptop or smartphone. Is such a functionality already supported, or should I patch the software myself?

Jim,
please ask Farhan the same thing.
How are we supposed to know what he's planning?
For example, I am not a mind reader, but I am excellent at correcting by laying on my hands. ;-)

Due to the size of the zbitx, the best solution is to expand the SD card, because the USB port is not enough to use a USB stick.

Trouble is, to swap the SD card REQUIRES disassembling the radio - at least
removing the case. Not an "in the field" friendly operation. Having a proper
shutdown command sent to the Raspberry Pi greatly reduces the chance of SD card
corruption.

Hi Guyula,

I looked and I still can¡¯t seem to find anything about rebuilding the file. Any ideas?

I use a mini bluetooth keyboard/touchpad with my zBitx. The touchpad is a little jumpy but it works. The RealVNC viewer also works well with a laptop computer.

Re: zBitx keyboard and monitor recommendation and advice

i suggest that you get a microUSB Port extension with at least 2 USB Connections like this
AuviPal 3-Port Micro USB OTG Hub...
this plugs into the zBITX socket. ?Then you just need a small QWERTY keyboard and mouse. ?For the Monitor connection you will need a miniHDMI to HDMI cable like this
Thsucords Thin Mini HDMI to HDMI...
to connect the miniHDMI port on the zBITX to a regular monitor. ?

Re: zBitx +-2 MHz transmit spurs?
Are other people not finding problems with spurious mixing spurs around 2 to 3 MHz above and below the Tx signal of your zBitx?
You can listen in with any wideband SDR such as an SDRPlay or RTL-SDR connected to very small sniffer antenna (paperclip).
If other people are not seeing strong spurs, perhaps my unit has a bad MS5351 clock chip or faulty bypass caps that I can fix. ?
Thanks and 73, Ron, n6ywu

Thank you so much!? I have never had an SDR QRP rig before.? I¡¯ve have TT Powermites and Argonaut 505 and 509s as well as anHW-8 and had HW-7&9.? This is a whole other ballgame.? I¡¯ll probably pick up a Bit-X at some point as there is a large following.? Thanks again!

It is not a BitX.? This link should get you started.

Re: Tiny GNSS Clock for the Field
Hi Li,
?
? ?I have a number of devices with so-called 'real time clocks' including Teensy 4 and RasPi devices.? I end up removing the battery as some clocks emit RF ticking, and not one of them has actually kept reasonable time over a 24 hour period.? None of the devices I have keep time accurately enough to use?WSJT-X modes.? I do not have a zBITX so can't speak to how well that RTC keeps time.
?
? ?When I'm on land and using my Ultimate3S WSPR rig from QRP-LABS, I use a GPS input and never have to worry about setting the clock - it's "never" off.? I use GPS timing when I'm at sea and away from cellphone coverage for the same reason, whether using digimodes or when timing celestial navigation sights (a work in progress...).?
?
? ?When the device is GPS disciplined, one doesn't have to worry about setting the clock - the device becomes a 'toaster' - it just works.

Re: zBitx keyboard and monitor recommendation and advice
Given that one can set up a zBitx from the command line, one can just ssh in from anything that can connect over the network. ?
?
Since most people carry a mobile phone with them when doing portable ops, an ethernet dongle or two (a small OTG to ethernet hub for the zBitx, a small ethernet to Lightning adapter for the iPhone, or similar for Android mobiles, plus a short ethernet cable) allow connecting to the zBitx, and are lighter than any HDMI monitor. ?There are multiple ssh terminal and Remote Desktop apps available in both major mobile device app stores.

Re: Tiny GNSS Clock for the Field
Li¡ªyou are correct. ?All of this GPS stuff is superfluous provided that you know your location and your real-time clock isn¡¯t terribly terribly off. Which isn¡¯t likely to be. And it¡¯s easy to sync with WSJT anyway. ??
However, for our field day effort, our group wanted to demonstrate full emergency communications capabilities without any Internet, and so we built an NTP server that is independent. ?We are an ARES group

We had to deal with this a year or so back, so that we could compete in FIELD DAY with FT8/FT4 without requiring any internet.? ?There are of course many ways to "sync" these signals and they are pretty resilient even to being off more than a second -- but we wanted a general purpose solution.? So we built our own NTP server using a cheap dongle GPS receiver and software on a raspberry pi.? ?Something similar should work on the SBitx etc...

We built ours as a standalone system and have used it in a couple of Field Days I think now with good success.
