interested in the comment that it would make the rig easy to build. If a

Don't know... I'll have to do a google search on softrock
and see what it is. If that *is* what a softrock is, I
may just have to get one to play with :)

The SoftRock is a kit, very inexpensive, with some
neat features and an incredibly talented network
of contributors joined together with the primary
developer Tony Parks, KB9YIG

you can afford that much I recommend you buy one. ;}
What a deal!

Interesting. Run PSK on AM and you get two sidebands for diversity
reception and a pilot carrier. This could make building small PSK rigs
easier...

What about DSB or NBFM, same result?

Maybe not quite as simple as AM, DSB, or NBFM, but probably pretty
If you place different data on either sideband, its ISB which is illegal or if
not now, may be in the near future.
However, if detecting either sideband independently does not produce separate
data streams, then its not ISB.
DSB would only double the information of one sideband so you would
