• 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.

Radtel invited us, the users, to send them in a Word document a list of Bugs and Features we would like them to address.
Hopefully Radtel will indeed fix and add whatever is needed.

Dumb question but are you using the 5/30 CPS and latest FW & DMR FW -- there are two. If you haven't already, you might want to reset the radio and reload your codeplug using the latest CPS.

In your PDF, you provide good information but lack any FW or CPS version info. Also, I would make two specific sections for "bug fixes" and "new feature requests." These are two very different areas and are likely going to be worked on by different parties.

I haven't seen some of your issues but I wasn't looking either. I'll see if I can repro them.

Thank you for your input.
I guess the RT-4D arrived at Washington State.
:)
I took it for granted that we are talking about the latest of all versions: CPS + Radio + DMR that were not changed in the past couple of months.
I guess it should be kept more in order, but it is a mix of all kinds of contributors.
Would you want to edit/add to the Word doc in Telegram?

Well the last DMR FW was on 7/07 but I was just making sure since the doc showed nothing of version info.

No it's not my doc. If you guys are happy with it then by all means submit it. I just think it's a little messy. They'll figure it out.

BTW, did you see the Radtel RT-6D Pro? It's pricey but I like it's keypad and overall design. It'll be out soon they say.

Yep, the document is messy.
The next time I or someone else updates it in Telegram, I will edit it according to your tips. Thank you.
I am a bit pessimistic that Radtel will address any of the bugs or requests.

I am trying to hint to Radtel and to other potential buyers (in Telegram) that before thinking about the RT-6D/Pro they need to fix their bugs and improve all the aspects of their Radio/DMR/CPS of the RT-4D. Hopefully they will not abandon the RT-4D completely.
I don't think it is worth it for them to have another similar closed-source buggy radio. They should model their product like the Quansheng that so the community can fix and contribute.

As far as I understood RT-6D is the same as RT-4D with a few hardware changes, but the Radio and DMR firmware, and CPS are the same.

I am fine with the low price of the RT-4D and its size form. I do not like large radios. I like to maintain a low profile, as you know :)

I really was only aware of the RT-6D without the Pro. Anyway, the additional GPS/APRS, Memory, Wattage Output etc. is not something I need, and for sure I won't pay 4 times for it.
In addition, I could not get the RT-4D to receive above 500 something MHz, (so their RT-6D advertising range is not true, if it is the same chip as RT-4D). They also need fix their advertising about Promiscuous mode. It does not include Time Slots which is a must.

I do like the middle knob to change channels and the multi-function buttons beneath the screen, if they are working, as with the Uniden scanners, for example. I do like the fact that programming is done via USB C at last.
Indeed the keypad layout with the 0 at the bottom is a "refreshing" look :)

We listened to your comments and made some improvements.
:)
Now the version numbering are mentioned, and the document is divided into Bugs and Requests.
We proofread it and rearranged it to be less messy and more readable.
Hopefully it is clearer now.

Radtel have a DMR Chip Firmware official update from about a week ago.
"(Fix issues related to abnormal digital chip sleep)"
I wonder what did they fix (no Change Log).
Perhaps they fixed the Critical Bug when the DMR (and Analog) stop receiving and the device gets wacko.
I'll try it with Dualtachyon's 40 Build over the weekend, probably.

I installed it today. It seems to work fine for me but I'll test it over the next few days. I'm using it with our local PNW Digital system here.

FWIW, I just read the enhanced suggestions and one that I would add. It'd be nice not to have the RX Group List required for DMR receive. Radtel forces the users to add the TGID to the Rx Group List. So if I add a simple Parrot channel, in order to hear a response, I must have the Parrot TGID in the RX Group List. Other vendors do not require this...

Another annoying CPS issue. It implies that I can show on the display, ZONE and CH ALIAS names. Instead, I get ZONE, FREQ and (small font) CH ALIAS.) I'd prefer the larger font size labels. The smaller font can be FREQ.

Thank you.
In the meantime two people have reported that this updated DMR Firmware did not solve the critical issue where the DMR/Analog reception disappears, unfortunately. So it is not clear to me what was changed.
I hope Radtel will answer that question.

I just found a similar issue where it was scanning and only gave me about 1/2s of audio from a TGID on the RX Group List. If I turn off scanning, then it's fine.

If you understand what this Change Log means, please let me know. It seems to me totally unrelated (I think it is some mistake):

Major Updates:
1. Fixed an issue with the polite mode for enabling dual timekeeping.
2. Added command 66 to set the analog wideband and narrowband transmission frequency deviation.
3. Added command 67 for companding, applicable only to analog channels 4829.
4. Modified the number of precsbk calls for alarm signaling, reducing the transmission duration and disabling digital calls during alarm signaling.
5. Changed the call hold time setting command to a value range of 1-30 seconds.
6. Added format 2 to command 51 to set the vocoder's AGC function.

Looks like commands related to the CPS programming. Perhaps they found some bugs in the CPS that were indirectly causing DMR signaling issues.

I updated my 4D unit and it's working fine. I'll need to wait until daylight to verify any real issues as the repeater is dead at this time of night.

A quick update: I turned on my Radtel RT-4D and set it for scanning. It went along scanning with no hits. I checked to see what time the net was suppose to be... and it was literally in the middle of the net -- the radio kept on scanning.

As soon as I stopped scanning and sat on the correct TGID/Channel, I received DMR audio. The RT-4D just doesn't like scanning on DMR..?

With that said, the audio sounds great, especially from such a small radio. Admittedly, I turned on my Baofeng DM-32 and went on monitoring from there. The [louder] audio output is much appreciated and the DM-32 is able to process DMR slightly faster than the RT-4D.
