Very nice; thank you!

It appears that the lower photos are from KO6NM, Mike Dorrough, the

All the best,


Kevin, WB4AIO.

If you live in the San Fernando Valley not so odd.

I think you both miss the point, however. SSB can sound BETTER than
AM. It requires more than a 3 KHz channel to do so, but the quality
is comparable to sync detection on DSB AM.



Yes, SSB can, if engineered properly, sound just as good in
frequency response and distortion terms as properly engineered DSB.
But it would require a pilot carrier and pilot-carrier-based AGC to
preserve the dynamic range as well as inherently carrier-based modes
like AM and FM. (This prevents any increase in receiver gain between
words and sentences.) This has been done, but is seldom seen.

There are quite a number of good fidelity amateur SSB stations on
the air these days (sometimes they are called ESSB for "enhanced" or
"extended" SSB) -- a phenomenon of the last few years, really. Not
surprisingly, quite a number of these stations also operate AM.


With my best,



Kevin, WB4AIO.
