Jim,

As Farhan mentioned in his message, we will begin taking orders for the V4 once we clear the backlog of zBitx orders we have right now.

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.

Hi Guyula,

?

I looked and I still can’t seem to find anything about rebuilding the file. Any ideas?

thank you, 73,

Robert

Mine also has the same on hold message and at the Cincinnati Hub

Noooooo.? ?Why?? ?Anyone else seen this??

Thank you,

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.

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. ?

your Buddy,

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.

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.

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.

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.

I purchased the rig in the pic from eBay about a year ago. ?The best I can remember it is a version of the Bit-X but not sure. ?I haven’t used it other than som RX because it didn’t have a manual and operation isn’t obvious to me. ?Is there a manual on the web?

sorry my first post was questions but that’s alli have until I start making contacts. ?Pic attached.
