Sir, what is happening, I think, is that the voltage regulator is oscillating due to the ENABLE pin floating. By bypassing that line will keep the regulator from crating noise.? That noise is getting

There's all kinds of graphics, and thus a variety of editors. Inkscape and yEd are two of my favorites, after GIMP. I did a bunch of work for The PMRC Blurb with Libre Draw back when I was

I added an office suite and attempted to add a small graphics editor. My sBitX is my holiday and vacation radio. With it I do not need to carry a laptop since the Raspberry Pi 4 (4gig memory in my

But filter caps are necessary when using AC power, I tried with my dc power supply and also ran it on battery.

No scope. Best I can do is measure ripple voltage with DVM? I’ll try that soon.

I bought it new from Gigaparts. I thought this item didn’t have a warranty so I fixed the transmit issue that it had when I received the unit myself.

I think some 7" displays have their own memory. Jack, W8TEE

I was talking about sBitx, which requires at least 2GB of memory. If you know Ashhar, you know that He likes to minimize tools. What we are talking about is that there is no 7" LCD display, so it

Good, then I'll guess: you bought it from another radio amateur. In this case, do not contact HF Signals support. Sorry to interrupt your monologue. -- Gyula HA3HZ

I haven't had your particular issue, but if it is the full sbitx, seek a warranty solution first. Please contact sales, support. After that, this forum has some very knowledgeable hams who can assist

Try this.? Put a .1uf bypass cap on the small voltage regulator board, pin 4 to ground. It is the ENABLE port on the board. Pin 4 is the pin next? to the large electrolytic cap on the main board

Thanks. Solved with your help. The sbitx.net site is obsolete... I think the a revamping is necessary... Bye Carlo

What support?

Contact support for a solution. -- Gyula HA3HZ

As far as I know, in addition to the audio injector, the Si5351 circuit is also needed for proper operation. -- Gyula HA3HZ

Nice interface. Too bad I don't use this interface. But regardless, I'll still try ;-) -- Gyula HA3HZ
