Neil,
Next, with a dummy load connected, if ypu just run the txcal from webui, it

I hope the power supply is juicy enough.

Sorry, this is my V2.? The DE is waiting for a dose of ambition to perform the mods.

Farhan,
This is from a known good power meter. I ran the calibration routines back when you first discussed them so the sBITX power readout is pretty accurate up to 17M and a few Watts off on 15 -

Neil,
Is this power output reading from your radio's display or is it from an

Can you remind us if you have a v2 or the de?

I had the same issue with my DE sbitx.? I had to reload the image on the microSD card, do the update, and then reboot.? After that, the mic worked again.

Re: sBitx DE (and also V2) notes and hints
Thanks Evan. I finally got around to doing that calibration. The number I settled on was 24999450. There doesn't seem to be any audible change unless the number is stepped up or down by more than 100.

Sorry to reply to my own post, but I was hoping someone could advise me.
Is there something I should be doing (see below) or should I be happy with these numbers?

Hi Ashhar, let me ask, just to be clear, the latest ./update is for the V2, which has no physical LPF relays. It seems to be working on my V2. What about the DE (which has upgrade #2, and the T/R

Unfortunately I just experienced what you all have been talking about. One of my inserts came loose (V2 #89). My quick solution was to put back the stud but secure it from behind with a M3 30 mm screw

That would make sense, but so far you and I seem to be the only ones having this exact issue. Mine is the latest software (updated Friday) and software would affect everyone using that version.
