I would like to scan the businesses around me that use DLR/DTR radios, as I hate not being able to listen. Which radio in the series would be best to use to discover and scan? Any advice from someone who has done this before? TIA

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.
Scanning DTR/DLR

I would recommend a scanner, as trying to discover using a consumer radio is a bit more tedious and they can be very balky to program.
I do most of my discovery stuff via SDR on a laptop, so there is also that route.
Not sure what your price point is, but the current gold standard is an SDS100...

For FHSS radios? Good luck with that.
You won't even detect the DTR/DLR radios with a scanner. They use FHSS in the 902-928 MHz ISM band.
If a business users is using them with the default group codes, you can use another DTR also set to the defaults and hear them.
I'm trying to remember what DTR and DLR stand for? I did a quick Google search with no luck. And what is FHSS? Can anyone explain please? Thanks...

Frequency hopping spectrum.
Basically it has defined frequencies
1 = 900.000
2 = 901.000
...etc(NOT LEGIT FREQUENCIES JUST EXAMPLES)
and the radio/software will randomly pick out of the 100s of possible combos for a frequency and spend like 1 second of talk time on that 1 frequency before changing to another one. Scanners can't track that fast. Also not possible to figure out it's next frequency
I didn't know that DTR/DLR were FHSS. whoops, thanks!
Yeah.....as was already said, not going to happen. There is no scanner in existence that can monitor these radios.
Each channel is a 50 frequency hopset, with no more than 90ms spent on each frequency.

DLR & DTR are model types of Motorola FHSS ( Frequency Hopping Spread Spectrum ) radios. There are DLR1060 and DLR1020 radios which run at a lower cost than the DTR600 and DTR700 radios.
I have used the DLR1060 as well as the DTR700 models and they work very well, within reason, considering the frequency range they use.

There's a lot of activity in urban areas using the default profile.
That’s kind why it’s important to carefully read the thread before throwing out best scanners, SDR’s, etc.
here in Pittsburgh at my location i have about 5 different company's in a 5 block area use DTR radio on public channels .. i just bought a dtr radio and scan all the public channels and i got all of the 5 places so i hear what they are saying.. most places around me that uses those radios just buy them turn it on and use them. my old school uses them as well on a public channel. i find most people don't really know much about the extra features on the radios unless they a radio/scanner Wacker like me lol ..
Well, in @a417 's defense, his post was the 1st post after the OPs question so there was no thread to read yet.
Thanks, but it's ok. I have little familiarity with DTR/DLRs. 36hrs and 9 posts later it's ok to monday morning quarterback me...I earned it!
Are there channels that can be set up to not be scanned or not able to be listened to? Such as a more private channel then FHSS already is

So default is like a "key code" and default I think is 0000. If you change that 0000 to something else, unless person plans to try all combos, they can't hear the conversation(s)

How many public channels does the dlr or dtr have? One day I may have to invest in one for how popular they are getting.
i do believe you can make private channels i would do your research im not great with dtr other then i setup the public channels to scan to see what's out there in my local area
