Re: zBitx firmware update using Macbook/Raspbian
Thanks for suggesting to try a different cable - turns out that was the issue. Now upto v1.06 :)

Re: Spectrum display window bug

If this does not work, I suspect some compile files are missing some data.

WSJT-X Audio Setup
- Settings-Audio, Soundcard Input: plughw:CARD=Loopback,DEV=1
- Settings-Audio, Soundcard Output: plughw:CARD=Loopback_1,DEV=0
- Right click speaker icon upper menu bar, select: audioinjector-pi-soundcard
- Right click speaker icon upper menu bar, select: Output Device Settings
- Click Capture tab, Maximize Capture slider.
- Click Options tab. Verify Line (Capture) is checked, Input Mux is selected and Output Mixer HiFi (Playback) is checked
? ? ? WJST-X Radio Settings- Rig: Hamlib NET rigctl
- CAT Control, Network Server: 127.0.0.1
- PTT Method: CAT
- Mode: USB
- I WILL TRY THESE SETTINGS LATER TO SEE IF THEY WORK FOR THE ZBITX
This is what my sbitx was setup?to work with wsjt-x
Joe? VE1BWV
Yes, i did resolve it. I thought i had documented or taken pictures of the settings.
I am looking thru my old paper work.
( I have sold the Sbitx a while back so don't have it to compare to)
Hmm maybe even in one of my emails. Checking

Joel, if I remember correctly, you had a CAT problem with wsjtx back in the 32-bit era. Did you manage to fix it?

Zbitx arrived with major issues
Well, my long awaited ZBitx arrived 4 hours ago.? Put the batteries in, connected an antenna and was soon listening to lots of stations on 40 and 20 meters.? But when I tried to call out, no one responded.? I got a friend to tune up and listen.? I heard him clearly, he heard nothing when I transmitted.
?
I then tried a local receiver, and same thing but maybe worse:? I hear no audio when in TX but do hear a constant carrier on the receiver on the Zbits tuned frequency (this is in SSB Mode).? If I start shifting the receiver off frequency, I can hear some modulation products 1.5 kHz away, but nothing with useful readability.
?
The SWR and power meter on the Zbitx show power and low SWR, as does an external wattmeter.? The ZBitx also gets hot, so I know power is being made, but that power doesn't seem to be related to the tuned frequency.
?
One last item, as I got finally frustrated, I picked up the Zbitx while in TX and heard noise from the local receiver.? Tapping on the metal bottom produced some tapping sounds in the receiver.? But even that was inconsistent.
?
So, I suspect something is loose/broken in the new Zbitx.? I don't mind trying to troubleshoot, but I'd much prefer having a radio that works as anticipated, as I don't have infinite time to waste fixing someone else's problem.
?
Has anyone else had similar issues?
?
What do you suggest as remedial action???

Re: #zBitx Tilt Stand for zBitx anyone?
#zbitx
2PCS Zinc Alloy Mini Foldable Laptop Stand, Portable Computer Keyboard Riser with 2 Adjustable Angles, Self-Adhesive Invisible Notebook Stand and Keyboard Lift for Desk (Black)
This works great for my zBitx.? Bill AG5ZN
Hi Pete,
???? I'm using a small calculator stand, because I haven't found anything better yet. But actually it seems to work well.

Re: Homebrew satellite control system that can run on sBitx
Some additional careful measurements with a spectrum analyzer, tracking generator and calibrated attenuators, the outside antenna, and such.?
?
the sensitivity of the sbitx on 10m seems right in line with typical HF receivers without a preamp. It was designed for maximum dynamic range! ?
working with the $165 Ukrainian transverter looks like I am almost to the noise figure/sensitivity that I need. ? Adding 10 DB or so of low noise preamplifier gain in front should make a great deal of improvement.
?
the $120 preamp on DX engine engineering looks like a good possibility of success. So it is ordered and we¡¯ll see what happens!
?
I have the advantage that I¡¯m not going to be transmitting into the same antenna, and I will put a diplexer in ?front of the receive preamp anyway to help protect ?

Re: Unable to Update Pi Zero
Hi Gyula,
???? I have burned the image file onto a new card.? But how do I get to the old card to replace it?? I removed the four case mounting screws but there are three more nuts on the bottom metal plate that just spin without loosening.

Re: zbitx - No Tx on WSJTX?
I am able to use grig to change the zbitx frequencies if I start grig with:?
grig -m 2 -r
so my optinion is that there is something missing from the zbitx hamlib.c?
Leo? AI5II
Same issue here. I am looking for the settings I used on my Sbitx, to see if that?helps.
As you indicated ft8 rx is working TX or any cat commands don't work

Re: Wifi Alternate - Can you copy wpa_supplicant.conf into boot folder to get wifi?
Could be. I never knew such a thing existed. I guess I should get one of those. Also a USB-C one (which I definitely knew about).?

Re: Homebrew satellite control system that can run on sBitx
I'm just a sucker for trying to use the least expensive gear....so even though the sBitx / transverter system just couldn't create enough sensitivity.... I ordered a GaAs FET preamp with up to 20dB gain in hopes of making the sBitx work on this project!

Here is the schematic of the board I made for controlling azimuth +/- elevator rotators:

Boards will eventually be available via a project on pcbway.com

probably impossible since the IF is around 40MHz
use a transverter

Gary,
Hope dies last because you've read a lot about it but haven't seen it in action.
This device is an RPi-controlled SDR radio, packed as small as possible, with its advantages and disadvantages.
Not all options installed on the board work, and several applications work differently than you've seen so far.

Re: Wifi Alternate - Can you copy wpa_supplicant.conf into boot folder to get wifi?
I¡¯ve had the same question for some time. For reasons, local access to the Pi, at least initially, is going to be difficult to impossible for me otherwise.

Re: Unable to Update Pi Zero
If nothing works, download the Image, extract it to .img format (32GB), copy it to a good quality uSD card with balenaEtcher and use that. This has the latest version.
