• 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 completely agree and I will buy a VHF model, for that price it's a great thing but I'm surprised that the Chinese brand this so involved. In the Facebook group I've read a few colleagues who had problems with TYT and MD-380, perhaps for that reason there is so much updating. Excuse my English.

You wouldn't be disappointed in buying one

There's a lot of design issues that are more of nussiance than anything else. Like screen color and font. In the sunlight it's extremely hard to see the screen well. Looks very washed out. Also the antenna connector. It has a special connector that isn't uncommon per se, just not the average you usually see. Another thing is CPU speed. Granted I'm in no rush to go through prompts and menu options when using it, but for people who like lightning fast. It is not. However when you buy it and do the firmware updates it runs significantly faster, but it's not like a 700 dollar MotoTRBO fast CPU.

Another thing like mentioned above is encryption standards. It has 128 bit encryption ( with latest firmware updates) but it's not the same 128 bit encryption Harris uses or Motorola. Every manufacturer has their own ideas on the exact encryption they use. So hence can inhibit interoprability in that aspect, but that's not s Tytera prone issue it's a issue across DMR radios in general. The 128 bit key Tytera uses is quite secure and the garbled voice output on the Enhanced Encryption standard for Tytera is similar to MotoTRBOs. Basic encryption is well basic in the sense you can't understand the voice behind the transmission, but can tell when someone starts and stops talking between sentences. Much like voice inversion scrambling on analog radios. The enchanced encryption is garbled fully and much more secure overall. Sounds more like DES encryption on ProVoice or P25.

I too wish they would do something with the screen color & font. As for the antenna connector, it's the common one that's been on Icom, Kenwood, & Yaesu HAM radios for years. What you see on other DMR radios is the commercial version that's been on Motorola HT's for years. So if I ever bought the TYT, I'd have at least 6 gain antennas that have been laying around for years to use on it. The Icom, Kenwood, & Yaesu HAM radios, as well as the TYT use the antenna that has the center pin in the antenna. Motorola radios, as well as most other DMR radios use the type where the center pin is in the radio, & not on the antenna. Diamond, & Comet have been selling the antenna with the pin for years, & it's much more common.

Is digital encryption is the same or similar to the analog scrambler? pardon my rookie questions. Surely many of my concerns is that I'm confusing DMR with TETRA. Is it possible to make a call to an ID and nobody gets?

On the Tytera there is no analog encryption scrambling. Only digital. There are other DMR radios that offer analog scrambling then digital encryption. Keep in mind analog encryption scrambling is not secure and there is software out there to decode it legally. As for the digital encryption end. At 128 bits, is quite secure. Even the Internet your using now on RR is only secured by 128 bits of encryption. It's simply DES standard encryption key length which the government entrusts for all non top secret information to be secured. All top secret information at the federal level is entrusted with AES 256. I'm just saying so you know that 128 bit is quite secure and more then enough for whatever you'll ever need to keep secret or talk about.

As for your call to and ID?? Please clarify what you mean by that

It is the language problem, sorry. You have an ID and I have another, can we talk without anyone hear anything?

If you are referring to a radio ID when you get your radio. That's just simply so other users are able to identify you. Almost all digital radios now a days have radio IDs as well as personality IDs. If your referring to that. That means nothing in the mindset for privacy. Privacy on DMR is solely achieved through encryption. Granted no scanner YTD can decode DMR voice as it is, but computer software can. If you encrypt your voice traffic then no-one can hear you. Preventing eavesdropping all together. Also keep in mind too with DMR. Let's say I am encrypted and your not. When you talk to me I can hear everything your saying in the clear. However since I'm encrypted all you will hear is garbled voice transmissions since its encrypted. You on the clear end of the conversation will need the same encryption key as me to be able to hear me clearly.

I am a DMR noob considering the MD-380 and CS-750 for amateur use AND monitoring of local businesses. For listening to business, it seems the CS750 has a slight edge with it's "monitor mode" which decodes all activity on a particular frequency. Will the DM-380 do this too or would I have to use my scanner/computer/DSD+ to gather the necessary information to program the DM-380 first? Basically, I want to compare the two radios for casual business listening and wonder if one allows me to do it with ease (not using my scanner/computer/DSD+). Thanks.

As of right now the MD-380 does not have monitor mode. However, it is possible that with future firmware updates ( it's software issue/design) Tytera may release a monitor mode as well in the menu setup. I have heard hear say from some people who claim to have pull with the chinese company that this will be added in the near future, but I don't know these people personally to verify any of their claims of who they know, etc etc. Like I stated its hearsay rumors that's all.

do your self a favor and save up for a moto, even the cheapest one, something like an xpr6550 or even the 3000 series . i bought an MD 380 just for kicks and its horrible.... i can key both my XPR 7550 and the md 380 in the exact same place and i cant get into repeaters with the 380.... it is not as powerful as advertised... its a Chinese piece of junk. just like the cs700/750

Thank you for the input. However this discussion isn't about the Motorola line. Though I'll say you might have had a bad one, since I have the completely opposite result here if a friend with a 6550 tries keying up inside my house versus my MD-380.

Thr Motorola radios aren't even made in the US; they're made in Malaysia, so folks that buy them are mostly paying for the name and batwing logo on them. And then they're paying several hundred dollars every few years to have the latest software and firmware updates available, which the "Chinese radios" give you for free.

Keep in mind analog encryption scrambling is not secure and there is software out there to decode it legally.

Where? I've never seen any programs that will decode encryption. I've also never seen any DMR portables with analog encryption. Inversion, yes. Encryption, no.

I wanted the CS750 since it has the monitor mode on it - but lack of FPP and some other quirks with it made me go with the MD-380. I love them - but wish they had the monitor feature the CS750 had.

Both the 750 and 380 have yet to complete their FPP, but both have it in the latest respective firmwares. The 380 will only let you edit channels while the 750 will let you add and/or edit them.

Analog scrambling is not encryption at all. If you re-read my comment I specify that.

I have to agree with the consensus and say you may have a bad radio. The specs on the radio are as stated. Does output 5 watts of power on both UHF/VHF. You do pay more for motorola, Harris and other big manufacturers simply for their name and the way they do business. Most of their radios too are designed in the USA, but many parts including circuit boards, bread boards, etc come from
China, Malaysia, and so forth. That's the way big Americans do business, sadly.

Also keep in mind this radio is designed for HAM users, not public safety grade, etc.

That's true. Some people pirate the SW... :D
Others do not need to make daily changes. They simply drop by a friend's house every once in a while to make any necessary changes. The friend didn't pay for the CPS either, but rather works for an entity where the software is legally used. I wonder what the policy is on that? Eg. Work uses the CPS for their 2-way system, but the employee uses the same CPS to program his friends ham radios.
