I was wondering if it is possible to reflash radio the has the Astro digital so it will do P-25 ? Thanks in advance

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.

I don't believe the XTS5000 ever had VSELP so in this case, Astro digital is most likely P25.
Post your firmware and dsp revisions.

The term "P25" is used very loosely, & I myself do not know exactly what it means. To some it means "digital" such as Imbe, or Vselp. So does the OP have a radio that is only analog, & needs it flashed to do digital? To others P25 means 9600 baud trunking, So does the OP need his radio which does 3600 trunking to be flashed to do 9600 trunking. I would be interested in learning the true meaning of "P25".
P25 means that the voice/data methods used conform to the APCO Project 25 Standard, and it defines a couple of things.
In the case of voice, it means the IMBE/AMBE+2 vocoders used in the PARTICULAR packaging specified by the P25 Standard. All voice transmission conforming to that standard is P25 voice... a somewhat interchangeable term is the P25 CAI - Common Air Interface. VSELP is not included in or compatible with the P25 standard.
There is also a range of constructed SYSTEM types that conform to the standard, that are termed P25 SYSTEMS. That's where you get the difference between the non-P25 SmartZone systems and the full compliant ASTRO P25 7.x (P25 Phase I/II) systems... which i term the way they are because they are not the only 3600/9600 baud TRS types out there - I don't like referring to specific things by nonspecific descriptors they match.
ASTRO Digital is Motorola's brand name for P25-compatible voice transmission.
Chucklynde, I think I see your question, but I'm not sure. Are you asking if a radio capable of P25 CAI Voice (but only conventional or SmartZone systems) can be reflashed to work on a full-on ASTRO 25 7.x Phase I system?
If you want to go for flashcode options, that would be going from a set including any of the below:
Q806 - ASTRO IMBE Digital Operation (especially this)
H35 - Conventional Systems Operation
H38 - SmartZone Systems Operation
Q173 - SmartZone Omnilink MultiZone Operation
to a set including:
Q361 - ASTRO 25 9600 Baud Trunking
If that's the question, with the appropriate flashkey, yes.

While I am not CERTAIN that "ASTRO DIGITAL....." should be construed to mean P25, it might be.
Isn't VSELP the FIRST Motorola ASTRO version?
I think "ASTRO 25" is the Motorola P25 term.
VSELP is definitely NOT P25.
And my understanding is that there is NOT an easy way to FLASH upgrade the older VSELP radios to do P25.

XTS5000 VSELP was not even an option. It has to be P25
Yes, you are correct about Astro Digital. It's a generic term for either P25 or VSELP. Just saying a radio is Astro Digital doesn't tell you much.
ASTRO25 is just a Motorola term which denotes the next series of radios after the Astro line which were capable of P25.
Changing a radio from VSELP to P25 is easy. Once the flashcode is changed to indicate that the radio is P25, you reflash it and the correct DSP will be loaded.
