NanoVNA-F V3 from SysJoint firmware beep


 

Hi folks,

I'm brand new here. I just got the NanoVNA-F V3 which is made by SysJoint.
Like with my other VNAs (a cheap small NanoVNA-H & a LiteVNA 64) the first thing I looked for was the (custom) firmware situation because the SysJoint NanoVNA-F V3 beeps every now and then and it's no possible to switch this off (I asked the SysJoint support).
So I was wondering ... I learned that there's another official manufacturer of the NanoVNA-F, Deepelec, and read that its firmware can be flashed onto a SysJoint NanoVNA-F, too?
But has the Deepelec firmware an option to switch any beeping off?
Are there other firmwares that can be flashed onto my SysJoint NanoVNA-F V3?

Thanks a lot & all the best,
Stefan.


 

Deepelec has not updated their firmware in several years and their architecture is not the same as your V3.

Why not open the case and disable the beeper? Put some tape across the output port or cut the PCB track.


 

I have found that all beepers can be permanently silenced with a pair of diagonal cutters. ;-)
A less invasive method is to stuff the transducer full with putty, Blue Tac, epoxy or similar physical means.

Ohhh, that's too bad. Is there really no software based solution?
I really don't like the idea of physically destroying something in a "brand new" (for me) device I just bought.
?


 

If Sysjoint does not listen to customers and provide a firmware solution you have only three choices: live with it, muffle it or cut the beeper circuit.
