Never heard the Science Set Back, have heard the Donald Duck label. Were you hamming in the 50s?

Why care? Because if you do piss one off and they find you either in your car or truck ( tag number/truck number ) or talking on your base ( house number ) talking where you should not be they will turn you into the FCC. There are hams that live to do this and that $10.000 fine and confiscation of ALL your equipment is no joke!
I am ham myself and i could care less where you talk and how much power you run but there are others that would want to see you fined for any reason.......just because you talk on a CB radio. -
My first license was dated in 1963. and by 1967 i had finshed school and held CB/HAM and the old FCC 1st Class ( Now General Radiotelephone Operators License ) when i went into the Army signal corps.
I would lissen to the debates about SSB/AM as a young kid and get to know the voices of many of the guys who were involved and MEET some of them before they became SK's. Yep it was just like today some loved SSB others did not .....

IMO SSB can be a pain in the rear while driving because you have to constantly "dial" the other party in with the clarifier, especially if their radio drifts around a lot. Which can take your concentration off the road.
Now if you were sitting at home and wanted to use the SSB, heck yeah. Go for it. It's an awesome mode to have.
They say it ain't a real radio unless it has SSB.
My 2 cents. -
FM is a far better mode in a car than SSB .... -
Does a 10 meter have SSB??

There is a reason why aircraft use VHF-AM as opposed to FM: FM receivers 'lock-on' to a single signal, so it 'captures' a receiver, excluding all other signals. If you are trying to listen to one driver and he's pretty far down the road, a slightly stronger signal on the same frequency will capture your receiver, locking out the one you want to hear. You can only hear one signal at a time. With AM (and SSB) you can hear multiple signals, even if they compete with each other. The idea with aircraft is that you want to hear both signals if there are two aircraft within range of your receiver. The same would make sense with trucks.

Aircraft radios have been AM since the first ones in the 1920's ALL military Radios on 125 - 240 mhz are also AM however in the 225 - 400 mhz range many have both AM/FM modes. I used then for my first HAM staion on 2 meter AM back in the 60's I worked on them at several places in both production and engineering however Aircraft use AM because they have NO REASON to change over and it's unlikely they ever will.
The REASON Cb will not go FM is BANDWIDTH otherwise the FCC would have allowed it back to day 1 ( 1958 )
I work on FM radio systems and there is a good reason they rule just the fact many use REPEATERS makes AM or SSB next to useless .....

Hi Bruce,
I agree with you about the benefits of FM. In fact, you and I have probably used the very same two-meter repeaters from time to time. I suspect that you and I have also used FM on 146.94 simplex. I seem to remember that there are even repeater links to 10 meters between Michigan and Florida and those are pretty cool too. I've never really given a whole lot of thought to the question of "What if drivers went FM on 11 meters?" or for that matter went to some form of digital like TDMA, CDMA, GSM or some other protocol that allows greater traffic on the same bandwidth. Again, I think that the issue of being able to listen to multiple signals simultaneously might weigh in favor of an archaic method like AM or SSB. Either way, we make the best of what we've got. Right?
Regards,
Clinton
