The new specifications will allow AM, FM, and SSB modes to be used on the standard 40 channels 26.965 - 27.405. Power output is 4 watts AM/FM and 12 watts on SSB.

Glad to see this side of the pond catching up to England and Europe, now all we need is for people to start using FM. Sure haven't been able to raise much interest here with the locals.
What is the Difference Between AM and FM Radio?
What is the difference between AM and FM radio? If you’re having trouble distinguishing these 2 radio types, read this article.

"Because FM waves don’t reflect off the ionosphere well, they cannot travel very far.
For good Frequency Modulation broadcasting, the station must be placed at the highest point or on high masts to enhance coverage."
Well that pretty much settles the question of, "why". If your communications aren't LOS you're pretty much SOL. LSMFT

You need to find better sources for information.
I can set here in California and work a FM repeater on ten meters in New York on 29.620 FM when the band was open.
There are lots of guys that have worked FM DX on 10 meters and 6 meters and.....
FM is a method of modulation, nothing more.
There are even guys that search for DX in the FM broadcast Band.

Same, last solar cycle I worked lot's on stations on 10 FM running 25w in the truck, simplex and repeaters.
I very much agree with the last two posts above. I used to work FM from the mobile into Europe quite often on the freeband. Worked 10m FM repeaters MANY times. One very popular one was located in the US Virgin Islands. I'm in Nova Scotia Canada BTW. European DXers have logged countless east coast FM broadcast stations. Mode has nothing to do with bouncing off the ionosphere. Frequency does. FM is wider bandwidth so the signal/noise ratio is worse but FM will CERTAINLY be heard around the world. The big problem as I see it is that people immediately think of the FM broadcast band when they think of FM. That is a VHF band from 88-108 MHz. Completely different than talking FM mode on HF.
Perhaps there are a few more as ignorant as I as to AM/FM radio and it's difference with "AM/FM modulation".
As it applies to FM modulation doesn't have the limitations of FM radio?
Those respondents having success with 10M, 6M and DX connectivity may it also be assumed for other bands, such as the CB Band?
Might I also assume these same respondents are also well endowed with towers, kilowatts, and the knowledge of repeater use.
Thanks Capt Kw for a bit of clarification. How that applies to HF bands could be the area of explanation needed for greater Advertising of FM use in the CB Band; for the lower crust, the out of the circle club.

The faceslap was for the guy's that wrote the article, windupradios, from that you can see they must not have much more experience than the am/fm radio in their car.
They confuse mode with frequency.
CBRS is in between 10 and 12 meters, both bands known for world wide propagation when open.
You don't need a tower, or multi kilowatt station, often you can work DX on these bands mobile with 25 watts or less.
And not only repeaters, fm simplex works just as well.
When the cycle is up, even on 2 meter fm you can experience sporadic E.
The maximum usable frequency can go as high as 200 Mhz at times.
In the UK they started with FM CB, right below 10 meters and those guys worked FM DX just like we did here on AM.
For the guy's that wrote the referenced article to say that fm mode is line of sight is just plain wrong.
Not everything posted in the internet is accurate.

As a note several years ago a radio station on the southeast coast of Nova Scotia put in an FM rebroadcast transmitter to extend it's coverage area. The delivered the audio to the TX site via what is called an STL, or studio-transmitter link. This STL was in the 450 MHz band. They had to switch frequencies after the first summer because the traffic reports from the WCBS Boston traffic helicopter was over-riding the STL feed. Granted this was NOT F-layer propagation but rather tropospheric ducting. REALLY strong ducting. LOL
I like to drive up one of our Mt.s here 7,000+ ft. and put up myA-99 (sorry) and run 500 watts and just lessen and call, I have heard some over 100 miles awy but no contact yet....may be a 2 el beam....? all for fun...What is the Difference Between AM and FM Radio?

Hey there Cookie55-
We have a small group here in west Texas and we recently started using FM. For local communications you can't beat the quality!! We love it and we're definitely glad that one of our buddies suggested we use FM, now that it's legal. If any of you have a group of people who like to talk on a regular basis, I highly recommend FM.
