[Boatanchors] SSB ***WITHOUT SUPPRESSED CARRIER***

[Ian]

I know of no prohibition against SSB **WITHOUT** suppressed carrier.  (SSB
is really SSBSC)

However the few times over the years that I've transmitted that way on the
AM bands people have sometimes commented on the audio not sounding as full
as it should.  

Advantage...somebody with an old receiver or one that drifts or performs
poorly with the BFO on can listen to the signal without using the BFO and
they don't have to return to keep their receiver on the proper frequency as
often.

Subject: [Boatanchors] SSB and carrier insertion?

Here's my question. I've begun studying for my general and I read in the
arrl book that inserting a carrier with one side band in not a legal
emission. Is that right? Could I have misread this? If I read that right,
can anyone explain why if DSB with carrier (am) is allowed and LSB and USB
without carrier, why wouldnt LSB-C or USB-C (with carrier) be allowed? 

As soon as I get my general and code passed, my transmitter is a central
electronics 100V (courtesy W0YVA). This radio has SSB and also SSB with
carrier inserted modes (also has PM, AM, FSK, you name it!) and I began to
wonder was this kind of emission legal at one time (radio was made around
1959) ? Does any one know when/why it became illegal? 

Also, what would be the benefit of running SSB with carrier? Does it make
the signal more easily detected? say, without the need for a product
detector, but just a BFO? 

Thanks in advance (for being patient with all my questions!) Eugene KC2NWG
