    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.

Digital on FRS / GMRS??

...As much trouble we are in as a nation and we are worried about the frequencies that some business is using...As a nation we have way more important things to worry about, than someones radio. Good lord. LOL

The thing is, the FCC is not concerned with lack of funding to education. They are not concerned with veterans getting proper health care in a timely manner. They are not concerned with ISIS in Syria. They are not concerned with which politician is using what email account for official business.

The Federal Communications Commission is only concerned with communications related matters, such as a licensee violating the rules and regulations that are set by the Commission. Or unlicensed users using a radio service that requires a license. That's their area of responsibility given to them by Congress.

MOTOTRBO

Not sure what the hate is toward MOTOTRBO, There are 4 huge DMR GMRS repeaters in my area of WI another one over the border in IL and one in MI.

I am 100% supporter of DMR and a licensed GMRS operator, I cant wait till DMR is the new standard.

2 conversations on 1 channel, crystal clear audio, unit to unit calling, text messages and GPS, Analog has nothing on DMR. I can hardly stand the bacon and static when I use analog now that I have used DMR.

I have been running a DMR repeater for months, DB-420 at 150' with an XPR 8300, it has about an 80 mile raduis of mobile coverage and 30 miles of portable.

If the FCC was going to come knocking it would have happened, I would guess the next revision of part 95 will include DMR as the spectrum management is superior to Analog.

If you don't want to hear DMR noise don't run an open squelch, there are systems on the same freq DMR and Analog play nice and nobody is complaining.

I travel most of the state of Florida many times every month. I have a radio installed in my truck and while I travel I like to listen to FRS / GMRS as well as all the business band frequencies. I recently have discovered what seams to be a digital platform being used on many FRS / GMRS frequencies. I can't tell if it is DMR or P25. However I do know that is it some type of digital format being used on these frequencies. I have both P25 and DMR radios that I would be able to use to monitor and find out. However, trying to find the group numbers or NACs is too time consuming. Does anyone know if this is usual? Thanks.

PS: No radio police or negative comments. Thanks.

Set your recieving to digital csq if it's older astro digital equipment. Modern digital set the recieve nac to F7E. Opens to any clear digital p25 traffic.

I think you figured this out on your own but the intermod from digital repeaters, especially the ones with really loud obnoixious grumble noises is the primary complaint, especially when people are listening on completely different frequencies using ham radios and scanners. Nobody's saying the technology is bad for the users of the systems but it hasn't exactly been great for monitoring.

Cory there is no hate towards Trbo or Dmr in general, as long as it's used in accordance of the rules and kept in the bands where it's allowed. GMRS is not one of those allowed bands and it's not likely to be changed. ;)

Not legal on FRS and MRS. Possible dPMR. There are some cheap radios out there that likely are bein programmed for those frequencies. dPMR is not authorized for use in the USA. Not compatible with DMR/p25

dPMR may be using NXDN.

I wish digital modulation were legal on GMRS/FRS. P25, DMR, and NXDN are already narrowband compliant since the modulation fits into 12.5kHz spaced channels. I'd like to go with the flow of what's being used in Part 90 radio services. Digital modulation could benefit GMRS in many ways if it were allowed but I don't see it happening anytime soon.

I also think that digital modulation should be allowed for GMRS but not for FRS since GMRS is a licensed service. Licensing can allow for more privileges than "license by rule" does. Cheap bubble pack GMRS/FRS radios might be priced out of the market if they had digital capabilities. So let the unlicensed bubble pack users stay with analog since they're not going to have a clue or want to spend extra money for a commercial grade digital radio.

Generally the more serious users of GMRS are going to use commercial grade equipment instead of bubble packs. They can easily afford digital radios instead of analog-only radios. The cost of digital capability has fallen in recent years and a brand new DMR radio is only slightly more expensive than its analog only counterpart. Since they tend to know more of what they're doing when it comes to radio, they are probably more likely to be licensed and would want to be licensed to be legit and protect their investment. Digital modulation could help solve the bubble pack problems on GMRS.

IMHO, digital modulation on GMRS could benefit GMRS in a lot of ways if it were allowed.

But was we know, there are those that the Rules don't apply to :mad:

Maybe. But many of us are satisfied with the systems we currently have in place and see no reason to try to fix what's not broken. Personally, I'm satisfied with the rules as they stand and the equipment allowed at the present time. :)

I think it would be cool to have the option to go Tier 2 or even in some rare cases Tier 3…unless the commission says okay I'm just gonna keep my wideband analog stuff up. Have enjoyed playing with DMR-MARC's network but I'm not in a pushy push mood to try and get the rules rewritten.

It could bring a lot of cool things in…but why abuse it even more than its being abused now.

My opinion is gmrs murs and frs should stay analog. Any digital play should be ham licensed Scenerio.

dPMR is great in that you can encrypt it.

Why? if it's that sensitive why not use cell phone or person to person contact? It is almost the Wacker scenerio but in radio land Wacker form. If it's doomsday I doubt radios or enc would help anyone and if that's case of a end world scenerio which is fantasy then why not just go full aes p25 using a 110 watt astro or apx and any channel since it would be zombie fantasy apocalypse. Reminds me of the bad idea of using enc in ham service. You'd still have to give it out to others if you want to communicate and in public world eventually it'll leak. It isn't like government.

I don't think anyone mentioned anything about "apocalypse scenarios"...and what's with this "whacker" stuff? I think this term is WAY overused, and is not applicable in this case.

It's not at all "whacker" for a business to want to encrypt their communications, IMHO. Whether it belongs in GMRS is another story.

Another side of that story is amateur radio should remain analog only and digital should only be for commercial services. There are a ton of older hams (who have been in the game since the FM revolution) who are that resilient to change. Also the guys that complain for weeks when a pl gets implemented on a 20 year old repeater.

In reality, GMRS is a spinoff of a part 90 commercial service. Business can be conducted over the service…so the real question is should the FCC continue to hinder a service that was once at the leading edge of communications tech (and in many areas GMRS repeater's were found years prior to amateurs even trying FM in the same areas)?

that is a valid question/point with grandfathered licenses using business on gmrs. As for secure comms in business sure. Private individual it's more is a toy for short time but to use secure everyone and his brother would follow if one or two did. Then not to mention the various formats coming out.
