Wonderful presentation !
In the USA Central Electronics was a big name. Many hams switched their AM transmitter to Double SSB then SSB using Central Electronics Exciters.
I do appreciate these types of learning videos I passed my U.K. test while in lockdown. .. keep up the good work. Takecare ☺️
That's great! Thanks for sharing. 73 Peter
Thanks for that great history lesson. A refresher for those like me that grew up with SSB back in the 60's, and for the new hams that are interested in the history of this mode. Keep up the good work, sir!
I learned about AM & SSB communication in the 60's while in high school electronics. This is an excellent refresher. Thanks, 73, KA2AHE. Ed
Glad it was helpful!
Thanks again, Peter, for an interesting and informative video.
All that talk about AM amongst the history of SSB makes me all nostalgic and want to dig out my old Codar AT5 Tx and fire it up on Top Band. Any one still using AM on there Peter do you Know ?
Used to love the Sunday morning rag chews. Interesting Video as usual by the way. 73's Dave G4FAQ
Hi Dave, thanks for sharing. Yes there are some AM nets but not sure as to sure where or when. Anybody got info?
Thanks, Peter - very interesting video - I used a B&W phase shift network in 1963 it was a pain - I went back to AM because nobody could understand me haha - we have come a long way - regards Dave
Many thanks fir that Dave
In the early 1980s when I was a lad I used to love to listen to the "old timers " that had huge AM stations whopping power ( my Elmer was one of those super power stations) they were clear as a bell. I had a good general coverage receiver so I could listen to them.
Peter brought up channelization , i started out my ham career with a Heathkit HW-101 SSB those days you tuned as close as possible to the other stations - things like traffic nets were difficult to get everyone into tune .
Thanks for sharing.
Hello Peter. In the USA, the Central Electronics 20A was probably the first exciter available. Phasing. I remember looking at the pictures in QST. But my paper route didn’t make enough. De AD0L
Interesting to learn - but I am old enough to remember that name!
Hi Peter ! Just a quick note for those operators in the US, our access to 60m is “channelized” to 5 designated frequencies only. Most all modern transceivers sold in, or for, the US market come with transmit enabled on these 5 frequencies only in the 60m band. (Leave it to us to make things confusing 😆!) 73 de Dan WD4DB
Hi David, yes 60m is the exception - at the moment! 73 Peter.
Thank you Peter. A very interesting journey through radio! 73, Mike. M0MTJ
Cheers Mike.
Even air-band is AM.
Great video Peter.
73 de Kevin, VK4KK
I was once told that AM was safer as two stations calling at the same time would be heard much easier on AM than on FM
Great video! Thanks for making this!
My pleasure!
Peter, thanks much for this lesson. You remind me of some of my most favorite college professors.
Wow, thanks! Not sure if that is good or bad!
Super duper explanation Peter… I like these R&Ds
✅
Many thanks!
Very nice explanation of SSB communication
Many thanks.
❤ thank you so much x
No problem 😊
Thank you for the well presented history, a slight exception to the norm is the 60m band which is channelised and USB. It is certainly interesting to see how the evolution of SSB generation has changed, my older rigs used the normal filter method the newest use DSP to generate it. It is hard to believe now but SSB did meet with some resistance when it was first introduced. 73
Thanks for the info! Yes you are right. There were some who vowed never to use it!
Thank you👍 I still have a KW Vicroy in the shed (not working) with its mate an AR88.
Nice 👍
The point about power is a good one. I find when I'm first to find a contact I can often easily make a contact with my 50w into VK or ZL but everyone running lots of power creates a need for more power, I can sometimes bust through a pileup though but tend to give up after say 4 or 5 attempts to avoid getting frustrated, as soon as the fun is lost best to find another contact i think.
Yes I totally agree. On the rare occasion I have been on the other end of a pile up I often pick out the weaker signals!
Hi Peter. Nice vidio on SSB and how it came about. Iove AM it's how I started in the late 70,s when I designed and built my first transmitter and reciever all good valves offcourse. Lol
Now I live in Thailand but sadly the only band we can use AM on is a very small part of the 10m band and nobody is ever on there.
Very sad.
Any3love watching your RUclips channel.

Hi Paul, great to hear from you. I can’t remember the last time I came across an AM signal but I believe there are a few nets here in Europe. 73 Peter.
Where in Thailand are you?

Hello 1st Thank U for this episode..
Hopefully you give us an episode about Astroplane Antenna and How it’s work to give 2.2 dBd and it’s similarity’s to half folded dipole use to be at repeater towers
Sorry it is not an antenna I am familiar with, maybe will take a look at it sometime. 73 Peter
G2DAF was the persin that br4oke SSB to radio hams in 1960 yntill then no one talked about it. he started working with ssb in 1941 int the radio develpmemt
The RSGB published a design well before G2DAF which I built and operated on 80m. The G2DAT design came somewhat later and was the first all-band SSB transmitter circuit published by the RSGB, which I also builtF
I wonder if younger hams question why FM and AM exist at all when you look at the quality of SSB audio on modern equipment.
A beer foe? How terrifying!
I thought that I remember that SSB was
developed by Collins Radio with a push
by General LeMay of the U S Air Force? 😊
Thanks fi4 sharing. 73 Peter
excellent video. VE3GUE
Glad you liked it!
Hi Peter, at 5:55 your marker was a bit off the carrier frequency, I'm afraid. 73 de Glenn ON4WIX
Yes about 20Hz but I think you get the idea?
Before I got my licence last year I picked up a monster Yagi antenna still new and in the box, I don't ever think will have enough room to erect it Lol OMG it is massive.A HyGain TH6- DXX Super Thurderbird, the faded instructions said when tuning to the "Phone End" of the band, What did that mean for the Love of God !! My 1st introduction to SSB. Kris ZL1KJT
For phone. substitute SSB. It was on e common to refer to any form of speech transmission as “phone.”
I don’t know if this has anything to do with your video but, in the US back in the 1950’s and early 1960’s, commercial am radio played popular music. It was very poor fidelity and mono only. Soon, commercial fm broadcast took over playing music as it had high fidelity and was in stereo. I was told that if you took two am radios, tune one down slightly and one up slightly off of the commercial frequency, the sound of the music would be slightly different, kind of a poor man’s stereo. Sideband?
I have not heard of this but there were some interesting experiments in the early days of stereo broadcasting.
I really miss the BFO control we had on receivers in the old days, the very one thing I would like to have seen on modern rigs these days. Thanks Peter for an interesting video once again. I remember the good old days of AM on Top band, 80 and 40, they were certainly exciting times for me as a young lad back then!
Couldn't agree more! Thanks for your support.
Very informative. It puts Dartford, my hometown on the map, along with Keith Richards, Mick Jagger, VOX Amplifiers and of course myself😊 VO1OK
Interesting info. Thanks.
Why don't the Comm Authorities of Countries declare certain frequency ranges only for QRP use of RF modes?
There are - 7.030 and 14.060 - examples of CW spots. Others for SSB - try Google search
The issue is your remark about "Comm Authorities." Voluntary standards set by hams themselves already exist and can adapt quickly and without bureaucratic hassles.
That goes straight out of the window whenever the next contest is on...
How about if dx land 😅😅😅😅
Unfortunately, with the advent and popularity of digital modes, SSB will eventually be a thing of the past. In the future it will be rare to hear a voice on any band. But isn't technology great?
If by digital modes you mean typed text, that'll never replace the ease of voice conversations and probably SSB for much the same reason texting hasn't replaced phone conversations. At most, digital voice modes may become popular, but that's unlikely to take over. Analog modes such as SSB and pre-digital TV fade gradually. Digital modes collapse utterly, which can be irritating.
@@Inkling777 My prediction is based on the many very young new hams I know that are only interested in digital modes and have no interest in speaking into a microphone at all. But it's just a prediction that's all.
In fact digital modes are starting to become less popular as the data exchange is both slower and unable to create a “conversation.” Even CW can beat it for speed of data exchange!
Interesting presentation. Thank you.
Another good one Peter
thankyou 73 Rob G3RCE
Many thanks Rob.
I hope you guys in England get more bandwidth in the 40 meters band along with your new upgraded power allowance. 73 de N3TGY
Could be some way off. We only had 100kHz originally.!
