Default Question of moment - SS - S-AM

So, folks - When Drake decided to call it quits, did decent SS S-AM
die? The Eton, a few Sony radios (and maybe some future JRC NRD?)

effort it deserved. For a fairly easy-to-implement innovation, it
does not seem to show up much...

The K3 has synchronous AM, effortlessly realized in DSP. You need a
base receiver for $1,600, a wide filter for $100 and the General
Coverage filter set. Run you abt $2k.


Just took a look-see. Mighty nice, would not need the transceiver
section, but still...

Still did not see how the S-AM is implemented, if at all, since it
seems to not be mentioned on the page. I understand that the 6 kHz AM
filter is required for AM use, and hopefully that general coverage
package would include a 4 kHz. It comes with a 2.7 kHz narrow, which
is about as tight as I'd care to go on AM. I also did not see a
passband control on the rig, so not sure how that function would
work.

The reviews it gets on E-Ham are obviously glowing, so there must be
something to it.

Thanks!

It's a world class receiver. Nothing else comes close for the money.
There are crystal filters and DSP filters. All the detection and
demodulating is done with DSP.
