Congratulations on your new site. I invite you to link to the West Coast AM site at www.ami-west.com. Over 400 strong and still growing.
All the Best
cool you can't have too many AM groups
That's the truth !
Also drawing attention to http://amfone.net
And for those who haven't heard the sound of an AM QSO lately, hit the link:
I agree, I have many "AM" video's on you Tube. Enjoy and remember, you cannot make SSB without first making AM......Unless someone changed the laws of physics last night while I was sleeping....Hi Hi
Enjoy Ron W6OM
Is that true? Sounds as if it could be. I don't think I've operated AM more than once or twice, mostly just to test something. Seems to me it's a mode that requires a lot more than barefoot power and modest antennas.
Technically, SSB is a form of amplitude modulation, only with one side band and the carrier suppressed.
It's possible to generate DSB (double sideband suppressed carrier) directly with a DSP.
I have DSB and never used it. On my list of things to try. But for now, I wouldn't know when I'd even use it over "regular" SSB.
Only if the receiving station is using DSB synchronous detection. Otherwise, it's a waste of transmit power.
BTW, pretty much all modern amateur SSB transmitters use a DSP to generate SSB. First a DSB signal (or more precisely, a series of digital values at some sampling frequency like 24 kHz) is created and then the DSB signal is run through a Hilbert transform to eliminate one sideband (this is also called the "phasing" method when analog techniques are used).
