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.

Can the repeater frequencies with no channel assignments still be used?

What is a repeater frequency with no channel assignment? That makes no sense.
All the ones after channel 22 on the bottom of the list, they have no channel assignments, starting with 467.5500

Those are the repeater inputs. They can -only- be used for repeater inputs, not for simplex.
You could plug those into your scanner and listen to see if someone nearby is accessing a repeater, or to hear if someone is doing something stupid on the inputs.
Did you read the notes for #3 right beneath the list? Those are the repeater inputs.
Found out after the fact.
Did not scroll down far enough.

Don't GMRS approved radios come pre-programmed with the correct frequencies?

Depends on the radio. Cheap consumer-grade radios that don't transmit on other frequencies do. The Kenwood and Motorola commercial radios that also have Part 95 certification don't come with GMRS frequencies.
And just to add, my radio did come with the GMRS frequencies pre-programmed with all the GMRS frequencies.
I will just need to add GMRS repeaters to the radio once I get the right programming cable.
I haven't really read the latest updates on the FCC's Part 95E the General Mobile Radio Service, but I'm sure the FCC hasn't added additional channels to the service. However, I notice the Amateur Radio 220 Band is slowly being occupied by other services, such as the FREDs or EOT Devices for Freight Railroads and I'm sure the PTC Positive Train Control Systems. I didn't any recent changes for GMRS or MURS.

PTC and other railroad stuff isn't in the amateur band. There haven't been any changes to the 222-225 MHz amateur band since the 1990s when 220-222 MHz was taken away and 219-220 MHz added on a secondary shared basis.
I may have gotten a few facts wrong in regard to how the railroad industry use the 220 band, but the railroad transportation industry utilizes the 220 band. I could have sworn that I've seen a 220 frequency within the Amateur Radio Spectrum used in the Remote-Control Devices for Yard Switch Engines. Maybe I'm wrong again, heck I'm always wrong!

"Band" is somewhat deceptive, as there are many, many bands as seen on this US chart. Many bands are further broken down by type of transmission, and/or freqs designated to specific business sectors or companies.

Today, the FCC maintains what are known as allocations of spectrum, but they can also be interleaved or shared with other services. 220MHz is one of those allocations.

it's already in Sentinel, man. i added my own gmrs system to my scanners but i use the national defaults for those services too and you don't need to do anything else but i use squelch tones on my household system that i want to log and record as such instead of other tones or lack of them.
chirp can download lists for frs/gmrs/murs for any supported radio!
