Anan 7000DLE birdie without antenna connected

I was testing my Anan 7000DLE with no antena connected (none) and found a very loud birdie at 2.092Mhz.

Any idea about what is this? (I can't hear it with my Icom trensceiver)

Please watch my video:

It's almost certainly an internal power supply spur. I have the same thing on the 8000 here, although it's closer to 2.040MHz. Others have, from time to time, reported similar findings:

For most of us these spurs are outside the amateur bands, but not for everyone.

Thanks for the info!

Out of curiosity I looked at that frequency on my 7000DLE mkII. I also have that signal at approx. 2.040 Mhz
