Hello. Wondering how important the original sbitx.db and the hwini files are from the original disk I got when I purchased my unit a few years ago? Before you ask, I DID back up those two files to a

Thanks Evan now it works. Ramón

I am curious about the voltmeter mod. Which two gpio pins does it connect to? I saw it uses two but the notes dont mention which ones. David [email protected]> wrote:

Thanks for the link, I'll definitely consider this option! ________________________________ Sent: Sunday, March 2, 2025 10:26 AM To: [email protected] <[email protected]> Subject: Re: [BITX20] reviving

Well, who knows how it got damaged. Don’t forget to put D7 back in there, and it wouldn’t hurt to put something even a little beefier like two or three of the one amp diode in parallel. This is

It was in fact one of the IRF510s that failed. So I will replace both with a fresh pair, then proceed to recheck all of the active components in the PA section. If all is well, I believe I will

With all the fanfare around the zBitx, I've heard nothing about sBitx. When will we be able to order the current, or next(v4) iteration of SBitx? 73 -- Mike - K8MCB

The 3D STL mount file and wiring diagram is on our Discord server :)

The file to verify is in /boot/firmware.? It is config.txt.? Attached is a copy that works for me: 73 Evan AC9TU

Thanks Evan, so far I have not been able to disable vc4hdmi0 and vc4hdmi1. how did you do it? pi@sbitx:~ $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: vc4hdmi0 [vc4-hdmi-0], device

My last sad experience shows that a possible extension could be a temperature sensor (with range up to 150 or 200 Celsius) placed on the heatsink near to MOSFET. The software could then limit or swich

JJ- Excellent work on the improvements with V4.4. CW is much more responsive and the full spectrum option (elimination of the decoder screen) is absolutely SUPER! It could be made even better with a

A diagram ( documentation ) of mounting the INA260 Power Sensor thanks

Works great!

I already ordered AlN insulators from Aliexpress. They should arrive in two weeks. 73, Wojtek SP5DAA

That’s great news! I would strongly suggest switching to the aluminum nitride insulators Gordon kx4z

Yep, at least I had a bit of foresight and ordered a few more pairs of IRF510s. I'm going to pick it up again tomorrow. I've found that in cases like this, more than a few hours and I start to get

Yes! Replacing the MOSFETs fixed my sBitx v3. So I have learned two lessons: * Running continuously in FT8 mode requires either reducing DRIVE or using a fan to improve cooling MOSFETs (especially if
