Saw one of those President AM FM radios in the box today. Noted there was nothing on the outside indicating FCC type acceptance but glaringly bold was 50w PEP being touted. Do either of these fly? I don't remember which model.

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

There is no way a 50 W radio can get FCC certification for CB.
As of October 2021 new radios can have FM with 2.0 kHz deviation but so far only about 3 models have been certified.

FM CB radios: All new mode now allowed by the FCC (walcottradio.com)
Also wonder if the Uniden x36 and SDS scanners will be able to receive. I would think so?

from the SDS manual and same for the x36 manual.
Configurable Band Defaults – Allows you to set the step (5, 6.25, 7.5, 8.33, 10, 12.5,15, 20, 25, 50 or 100 kHz)
and modulation (AM, FM, NFM, WFM, or FMB) for 31 different bands.

FM has been available for years and years. Good luck finding someone using it.
But was it legal in the US on the CB band?
No, FM was never in the US on the CB band. That's why CB radios sold in the US never had it. Only export radios and some 10-12 meter radios had/have it. Now that it's legal, some CB radios sold in the US will have FM.

How many tens or would it be hundreds of thousands of export radios sold past twenty years?
Now available on regular CB it won’t make much difference overall. I’ll guess it will be guys from one company in close proximity while off road and at a worksite.

The power rules have not changed. 4W AM/FM, 12W SSB.

Step size and deviation are separate things. Generally, an FM receiver will receive FM signals with less deviation than they are set for up to a point but they will appear weaker and they will receive FM signals with more deviation than they are set for up to a point but with distortion.

i copied the section to show you can change step size AND modulation.

Neither have the speed limits on roads and it’s doubtful you pay them much attention. Or texting while underway. Tailgating, etc.
So far as harm is concerned, let us know the year in which you adamantly followed every road safety law after research, interpretation and practice.
A typical Ford Fusion needs 180-feet to come to a full stop. I’d doubt you maintain 90+ feet separation at speed.
Big trucks need 700’. Ever gotten in front of a big truck to make your road exit at less than 100-yards?
— If CB worked well at 4W no one would upgrade from there. Get a clue.
Car installations need little “help” assuming a permanent-mount antenna. Start there and use a field strength meter. The dual-final exports are popular for very good reason: they work.

FM use will be considered popular or not based more on export radio users than any others.

Class D CB works perfectly well for its indented purpose at 4 watts. It is only when users attempt to turn it in to a replacement for Amateur radio that the low power becomes an issue. For the purpose it was intended Class D CB radio should never have been assigned a set of frequencies in the HF range with the potential for skip or with AM modulation which is much more susceptible to man made and natural pulse type noise.
Class A CB (what is now known as GMRS) would have been a more appropriate set of standards for what was to become Class D CB and should have been expanded and adapted to cover that assignment.

Pretty vague, don't know what you saw or where (you didn't note a model name?), but this is my understanding: President has a lot of radios that have a USA "FCC" variant and an "Everyone else" variant that doesn't have 'FCC' in the name. If you saw a box that didn't say "FCC" in the name, like a "Thomas" and not "Thomas FCC" then that box was smuggled into the US somehow unofficially, and probably should not technically be for sale at any reputable US radio store. The President Bill model sold overseas has FM and like 20 watts IIRC, while the President Bill FCC sold here is 4 watts and no FM. That doesn't mean some overseas models of the non-FCC P. Bill radio aren't floating around here... they just didn't come from a legitimate commercial source with the crown's blessing.

Based on the specs and the 50w being on the box it looks like it was actually a Ronald that makes it NOT a CB. A foreign compliance certificate is shown but nothing FCC so I'm guessing export only. My mistake folks.
Huh???? The OP asked if the 50W radio was legal. I answered his question. You don't need to post your nonsense again about speed limits and texting. Trust me...nobody cares. The OP asked a legitimate question and I answered it.
Personally, I could care less if people violate the law on CB. It is a desolate wasteland. You do you.

“Legal” is in the hands of the people and always has been. Bureaucratic rules aren’t law.
Encrypted radio as used by government is genuinely illegal.
Try for clarity.
