Eh, the author confuses DSB and AM. I wouldn't put much faith in
his/her analysis.


I wouldn't put much faith in someone who is confused over the gender of
the name 'Phil'. Ludicrous and a "poisoning the well" logic fallacy.

DSB never has a carrier. There is no such thing as DSB and DSB without
a carrier, just DSB.

Telamon:

Listening to AMBCB in the car where I don't have a sync detector and
home where I do sure makes me wish I had it in the car.


See my article "ferrite rods make poor car antennas".


Where? At Yahoo? I'm not a member.

The improvement in reception most radios have with sync detection is
huge not small and so the improvement is not open to argument.


Is SAM on your RX340 a huge improvement over SSB? (Yes it's a trap.)


SSB on the RX340 is superb. SAM works great most of the time. The SAM
does have the locking problem when you encounter rapid deep fades the
AGC system in the radio can't seem to handle properly. In those cases
you can usually fiddle with the programmable AGC settings to get an
acceptable response. Only other solution is to use an antenna less
susceptible to rapid fading. That would be one with larger cross
sectional area. The SAM can lock on very weak signals and is side band
selectable so with DSP filtering it usually makes adjacent channel
splatter disappear. SAM usually works like a champ.

You really get really excellent sound from this radio as you can
increase the bandwidth as conditions allow for SSB or AM.
