Does this receiver have some form of SHARX? In the first video the radio seems to narrow the selectivity after a few seconds, which is how my car radio behaves when receiving weak signals next door to strong ones.
Good DX.

It doesn't seem like that to me.

The radio has direct frequency entry, but there is no "enter" button, so there is a delay before the station is tuned in. I am using directivity to peak the weaker signal, which is remarkably good given the small whip.

I do think the chip has some sort of DSP however

Thanks for watching.

You'd expect that the Play/Pause button would function as an Enter button for direct frequency entry (I assume you have tried it ) ??

Any manual available online for this Bannixing D-68E radio ?

Is it's range the usual 87.5 to 108.0 MHz or does it cover lower than 87.5 (taking in Japanese band as well?) ?

How does it behave tuning on the up/down ( << >>) buttons?

?

The buttons you mention don't function for manual tuning, they are concerned with auto preset and memory recall. (Also navigation in MP3 player mode)
