It's all about the Software

Just noticed this error(?). When selecting Pre-Amp on/off a window pops up saying the AGC must be off? Pre-amp works just fine on or off with AGC on.
Just uploaded the latest, V3.3 build 3236 on a W10 laptop

Did you just update the AirSpy HF+? This might be a new feature of the update? That doesn't seem likely; but, I am willing to bet it's a bug. On an HF tool the preamp is usually not needed, especially with big antennas. So that may be why nobody has run across this before?

I see this dialogue on latest 3.3 Release build, but I have not yet updated firmware on HF+. What's odd is although it says AGC must be off, it's clearly (audibly) turning the pre-amp on even with AGC On. I wonder if it's a bit of text that Simon forgot to remove during one of the updates? I don't ever remember this being a prerequisite with the HF+?

This was discovered the day before the firmware update. Checked it again after and it's still the same.

I'd suggest sending a question about it to Youssef. That would nail the lid on the source of the problem's coffin.
