Re: Fixed: cw latency and wsjtx/flidigi sidetone

Even after the update to 3.052, working with straight keys isn't possible. There are a lot of dropouts. The "dits" at the beginning of the characters aren't sent, even with a delay of 500. This isn't right! The annoying noise from the speaker is now audible even at volume 0. It's annoying!

If you have the option to select CW, the radio may have been updated with Munter's fantastic BitX40 software. The attached manual shows the hardware mods needed to operate CW.

Re: Fixed: cw latency and wsjtx/flidigi sidetone
Now
it’s on the way to get really fun in CW ... just upgraded? v 3.052 , much
much better.

I have a minor update to make zbitx work with wsjtx/fldigi/etc
and fixed cw latency.
You have to update just the raspberry zero.

From a terminal window, type this:
cd ~/sbitx
./update sbitx
this should do it

Can we someday have change logs for the zBitX firmware and screen updates?
The title really says it all. I know you guys are really busy, but sometime there's a lull, maybe start posting some kind of change log update documents for the new and wonderful firmware you're cranking out? I'm really in awe of your ability to do all that. It's been years since I did any sort of coding, and most of what I know now is obsolete. So I'm always glad to see the change logs, because then I know how much is changing and how fast.

Re: #zbitx I would really like a formal way to shut down the software gracefully
#zbitx
Received my zBitx via DHL yesterday, and powered it up today. ?Used a micro-USB to ethernet connector, and ssh'd in.
To power off without wearing out the barrel connector, I purchased a 5.5x2.1mm inline power switch (for Arduino's).
I first issued a shutdown command, waited about 10 seconds, and then hit the inline switch to remove power.

No, thank goodness, it will be just like the V3 only with a Raspberry Pi Display 2 in it. Farhan says there will be some other facelifts also, so basically it will be like a V3 only better.

Will the V4 still have the PI-4 or will it be like the zBITX with a pico?

First CW contact on YouTube
Thank you Ashar :)

Displayed log time is incorrect on this screen, but is correct when I view it via VNC. I'll open a bug report.

If you've been watching this thread for an update, like me, then look instead at this thread. I've applied the patch and early testing shows it works FB with no latency, and QSK at 50mS. 72 y'all

Re: Fixed: cw latency and wsjtx/flidigi sidetone
I take that back? Once I opened wsjt-x and? hit tune from there, the tune on the zbitx panel started working?

Re: sBitx v3 - next final MOSFET killed
Wojtek,
?
I'm sorry you went this way, but you can learn from your own mistakes.
I'm just recommending it, because it worked for me (it's true that I'm not using it in remote mode) that the power supply protects against overcurrent intake with current limitation.
Before replacing the FETs, it is advisable to select the new ones with almost the same opening voltage. Bias setting should be done with a maximum 2.00 A power supply.
I have v2, which has an IRFZ24N built in, and these are more sensitive to overvoltage and overcurrent.
I replaced it once because I tested it on a battery (without current limitation) and I'm still using them.
I think this is due to the current limitation. The limitation is 12.5V and 6.50 A.
I currently have over 10k connections in 1.5 years and I use one antenna (without antenna tuner) on 3 bands (7-14-21MHz) with a slanted vertically fed delta loop antenna.
In short, I am satisfied with the v2 hardware, although I have made several small modifications.
Most of them were aimed at reducing the temperature.

A while back at a hamfest I picked up a mystery radio being sold by a guy selling items from an SK's estate.? He didn't know what it was at all, so I got a good price on it.? Bringing it home, I found out that it's a BitX40 v3.
The builder didn't label any of the buttons or knobs on the radio, so I had to figure those out myself.? Got it all sorted out except for one switch that goes to another smaller board under the main PC board, but that'll be a question for another time.? There apparently have been multiple mods done by the original builder to the radio, but so far I haven't been able to reverse engineer what's been done to it.? It does work great and has great receive audio as well as good transmit audio.
Right now, the things I want to figure out is how much power output the radio should have.? All other Bitx's I've had are 10W output, but this one seems to only be 5W with one IRF510 final. If 5W is what I can expect out of this radio, then fine. I was making contacts on a net last night.
The radio was built without having a hookup for a CW key.? I'd like to install a CW jack so I can operate CW with it.? I did find a schematic but can't seem to find where to hook up a key to the circuit.
Any help appreciated.

sBitx v3 - next final MOSFET killed
Hello,
My sBitx v3 has killed next final MOSFET. Again, as previously, only one was dead: However, this time the failure wasn't caused by overheating (the fan was cooling the heatsink and its temperature was ca 30 C) but by SWR.
I was operating my device remotely via WiFi in FT8 mode, and my ATU got crazy. Unfortunately, I could only see the increase of SWR on my laptop, and the connection got broken. I couldn't cease the transmission immediately. When I reached the sBitx, it already showed the output power 0W.
Well, when replacing them, I have exchanged the mica insulators with AlN ones. Let's see how long is it going to survive now.
BTW. Is it possible to replace IRF510 with other MOSFETs (maybe more expensive, but offering higher maximum voltage and better power at 28 MHz)?
?
