The DE321 and KA321 are actually digital receivers made to look like analog receivers. According to this review, this design doesn't work well for tuning weak signals.

It's possible that the R-2010D has the same problem tuning weak signals, since it apparently uses the same DSP chip as the DE321 and KA321.

A real Analog radio wouldn't mention 9 or 10khz steps, there aren't any.
The BCL-2000 is a analog radio with a digital display. What it does have is a freq counter that compensates for the IF.

Jeff, read this article http://www.businesswire.com/news/home/20110124005766/en/Silicon-Labs-Cost-Saving-AMFMSW-Receiver-Solution-Tecsun

It's digital tuning, analog readout. The 350 and the pocket-sized Grundig Mini 300/Tecsun R-919 are analog tuning/digital readout.

For those who prefer a purely analog SW receiver, Tecsun and Degen make many of those, too. The tiny, cheap Tecsun R-911 is very good on AM and SW.

In Tecsun radio 2010D,as the analog dial has different dial spreads for FM 1,2&3,so that analog and digital readouts match.
My querry is,then they ought to have similar different dial spreads for AM 9/10 kHz steps(one for 522-1620 & other for 520-1710).Otherwise it will show wrong dial readings when step is 9 kHz on 520-1710 scale,won't it?
And btw Paul siver one looks cute.

This ShouYu SY-X5 radio has two band spreads for AM-one each for 9/10 khz steps.Thats what I was referring to in my above posting.And it's based on same Si484X DSP chip.

I think you're right, Vimal. I also like that the SY-X5 can be powered by either the rechargeable battery OR standard AA batteries. That's the first time I've seen that feature.
