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

Re: zbitx - No Tx on WSJTX?

 

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

I have WSJTX running nicely on a 2nd monitor on the zbitx except that it is failing to trigger Tx with a hamlib error shown in the terminal window?

Can anyone share their working WSJTX radio config for the zbitx?

Many Thanks

Re: 6M

 

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

Wouldn't a micro usb Ethernet adapter work also? Allowing you to access internal RPi?

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.

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.

Re: Unable to Update Pi Zero

 

I copied the zbitx Image today because I was curious about a problem. I have sbitx v2, the hardware is different, and the program logged in fine after starting it.
If you changed the password in the RPi menu-> Preferences -> Raspberry Pi Configuration settings, use that.
It does not ask for a password to enter the terminal. I do not see a link in the manual to ask for a password.

Try using "raspberry", that looks like the password for the Rasberry Pi itself.

Just joined the group.? I ordered my zBitx on Friday....on the 4 week waiting list.? Looking forward to playing with this radio.? I belong to a group in Chandler, AZ called "BE-HIP" (Hams In Parks).? We take our portable radios out to local parks and setup our stations.? This radio is perfect for that.? I am not the big of an FT8 fan, but with it built into the rig, it makes it much easier than dragging my laptop and support cables out to the park.? Currently I am on the upper end of the price spectrum with a KX2....

Re: Unable to Update Pi Zero

 

hf12345 does not work.
6M

 

Is it technically possible to open the sBitx / zBitx to use 6M or is it hardware limited?

Spectrum display window bug #zbitx

 

I don't know if anyone has noticed, but the spectrum display frequency window is not centered on the frequency, the water fall is perfectly aligned but not the spectrum. I hope I explained this correctly, I'm sure someone will tell me if I didn't.

Re: Unable to Update Pi Zero

 

Hello Gyula,
???? I am following the procedure on page 22.? When I hook up HDMI monitor, keyboard, and mouse...then power up the zBitx, here is a pic of the screen I see.? No password, even the default password, works.? I cannot get past this screen.? Note that the zBitx is still waiting to load, so perhaps that may be why I cannot get to the terminal to do any updating.

Re: Carrier line

 

It is a "birdie"??
All receivers (well, most anyway) have them.
You can try more internal shielding on the radio (there was a great thread on that before, suggesting that shielding the display cable was the frist step) to try and reduce it.? ? It is unlikely?to be a single component? ?It is a real signal.? ?Just one that isn't coming in from the outside.

Good luck!

Re: CW decode

 

Andrew,
There was a comment here on the forums that decode works best when the radio's speed is set to the incoming CW speed. And, as others have commented, don't rely on the decoder, for when it misses then you are up the creek without a paddle to decode in your head.

Re: Unable to Update Pi Zero

 

Ed,
could you please clarify where you got stuck. They have published a manual for zbitx, where pages 22-24 describe how to do it.
