Re: Any update on ft8 messenger you mentioned before?

 

Still haven't had a chance to dig into the software, so I'm not sure if this is expected by default or a change on your end, but the error is just that there are local changes to a file that haven't been added to the git repository. The fix is likely simple, though you do run the risk of tying yourself in git knots. Probably worth a trip to YouTube university (or making sure to have a backup).

If you want to soldier ahead, two methods would be:

1. Revert any changes and try again.

Running "git stash" will restore that file to it's canonical state in the repository. You can return your changes by running "git stash apply"

2. Save the changes

To add the changes to the repo, there are two steps. After navigating to the root directory of the repo, you can "stage" all changes to files already present by running:

"git add -u ./"

Then, you can commit:

git commit -m "my changes"

Then you can try updating again. If git can't figure out how to merge the changes, it will put both versions in the file in question and ask you to edit them manually (pain).

In the meantime, one really nice tool for looking at the current state of the repository is gitk, which can be installed via apt. Just install and run while in the repository: "gitk", and it will pop up a GUI with changes. Then you can see what's up with that file (I'm assuming it's a file and not something more complicated like a submodule).

Will try to fire this up later today or tomorrow to see for myself.

i got my unit on May 20th.? I have been slowly working all the modes and frequencies.?

I have the same problem with paddle when trying to send above 17 or 18wpm it seems.? Also, if i run stand alone (no external monitor or no web mode) then the macros seem to work fine but when ever in non-stand alone mode, as you said they start and stop part way thru.? I have found no pattern to it.? The stopping seems random

I also can't get straight key to work very well.? I am starting to read thru the emails to see when I can find on these issues.

What software are you using for the Nano?? That can influence the calibration method.

Since it is receive only, zero beating is the best solution that I know of.? Any known CW, AM, or FM source in the receive area can work.? Tune the radio to the signal source frequency (I use a known, accurate signal generator) and follow the general steps of:
1 - Adjust the BFO to receive the low-frequency audio tones by positioning the plateau to the left of the 300 to 3,000 Hz range

Sbitx v3 frequency off by 300 hz

 

?Can anyone tell me how to adjust the frequency offset on the Sbitx? To hear any frequency ie 7.196 I have to use 7.196.3 ¡­ the truSDX has a setting for this and I am hoping this radio does as well.

Thanks in advance, Niles. KC8RJH

old calibrating uBITX

 

Hi everyone, I built a uBitx v5 (so 11.059 filter) from scratch only receiver. I know it's an obsolete and trite topic, but I wanted to ask you if there is a good method to calibrate its VFO and perform the calibration. I've read a lot of things, but I can't do it optimally.
I have calibrated the frequencies output from the raduino via software. But the receiver I just can't understand the logic.
I hope to receive some safe suggestions, to then transfer it to a container.
Also, the VFO calibration and calibration, must be done on an amateur radio frequency or on a commercial one (also much debated)?
Thanks and 73 by Antonio IU7SUX


Re: Activate auto-hotspot on zBitx?

 

¿ªÔÆÌåÓý

Is there any way you can carry a cable to connect direct to a router in where ever you are staying? ?I am an old newbie but I can connect my Bridgecom hotspot (for DMR) direct to the router in the condo we rent each winter and therefore don¡¯t have to connect through the wifi. ?When reading your email I just wondered if that was possible in this case. ?If I am way out in left field I am comfortable out there as I have been there much of my life.

Many of the motels and condos we stay at have the router right behind the TV. So for the gurus out there is the above thought possible with the zBitX? ?Remember guys, I am a big proponent of the ¡°There are NO dumb questions in a hobby¡±. ?Please be kind. Ha!

Waterfall and CW decoder on/off

 

The receiver noise would go away if the waterfall could be stopped. Could someone put a "Wfall on/off" icon in the SET or MENU functions that would stop the waterfall.
It would be nice if the CW decoder could be stopped as well.

The says:

It is a hungry radio in terms of power consumption. It draws 500mA (4.5 Watts) just when it is turned on and I¡¯ve seen peaks up to 4A on transmit.

Your fifteen minutes at 4.5W would mean the batteries were asked to deliver 60W for a quarter of an hour so 4*4.5=18 watt-hours.??
?
suggests a typical 3000 mAh battery is around 11 watt-hours, two would deliver 22 watt-hours.

My late night couch math suggests that perhaps the batteries weren't exactly duds, especially if priced accordingly.

Sorry if I made any mistakes, corrections are welcome.

Either way, I would be interested in the listening time you get on the two fresh 18650 batteries, along with their milliamp-hour specification.

Zbitx Mic(HT) Wiring

 


Built this wiring harness this afternoon to convert a HT Mic(Kenwood connector style 2.5mm/3.5mm) to the Zbitx, and I assume it would work with the sbitx.?

The microphone's speaker is amplified, I tested with a regular mic and found the sound levels were too low. The amplified audio on the mic really helps.?

The one thing to take note is that the speaker(EAR) needs to be connected as well because the MIC and PTT take the ground from the EAR's ground. If it's not connected you won't be able to TX.?

I haven't tried it on air, but listening to myself on my other radio and it sounded really good. About the same level as the internal mic.


Re: First Satellite Downlink Reception over sBitx (for me at least)

 

Unfortunately, SATPC32 does not appear to be able to do CAT control via Hamlib (otherwise it would be easy to control the sBitx)? -- but it can control ICOM type CIV on "Radio2"? ? Unfortunately, it also does not have capabilities to handle an sBitx with a TRANSVERTER.
?
There are probably many solutions to this, but I have limited skills.
I already have an ICOM emulator system that can handle CI-V commands over serial port (see the WIKI for MODS)
?
If I then intercept the CI-V commands coming from the SAT32PC program, and adjust for the transverter, and then forward them to my icom emulator -- that should work.? ?( A brighter person would go directly to the hamlib interface over tcp/ip....but I don't know quite how to do that....)
?
I think I can do the interception with an Arduino, so maybe I'll work at that.... or alternatively I could just alter my ICOM emulator and produce versions that are based on this or that Local Oscillator frequency!? ? That is probably the easiest way!!? ?I may work on that.
?
In that case, I could have the sBitx with its spectrum display, paralleling the receiver in the ic820H simultaneously.? ?That would be quite nice!

Finally I can Boot zbitx From USB

 

I finally managed to boot from an external USB on my zbitx.
I had to modify /boot/cmdline.txt? on the internal sdcard to point rootfs to the external device UUID.
Of course if I remove the external device the zbitx doesn't boot because it is waiting for the root file system which is not there .
Not sure how the zbitx boot process works but it appears that the internal sdcard is needed to actually boot from the external sdcard. Not sure why that is?
Once the zbitx is up and running on the external device I am able to unmount the internal sdcard and everything runs ok.
/dev/sda1 is mounted as /boot and
/dev/sda2 is mounted as /rootfs
It looks like what is needed is a? check to see if the internal card is present and the external card is not then boot from the internal card and its file systems otherwise boot from the external sdcard?
Ideas?
?
This is what I did.
?
1. Ran sd card copy creating the USB mounted sdcard partitiongs changing the UUID's.
2. Copied `/boot/bcm2710-rpi-3-b.dtb` to `/boot/bcm2710-rpi-zero-2.dtb` on the internal sdcard.
3. Copied `/boot/bcm2710-rpi-3-b.dtb` to `/boot/bcm2710-rpi-zero-2-w.dtb` on the internal sdcard.
4. Added `program_usb_boot_mode=1` to /boot/config.txt on the internal sdcard.
5. Modified /boot/cmdline.txt changing rootfs to point to the UUID of the USB sdcard rootfs.
6. Rebooted the zbitx.
7. Unmounted the internal sdcard boot and rootfs dev's.
