UV380 + DM-1701 Beta 2023 03 08
UV380 + DM-1701 Beta 2023 03 08
A new Beta is avialable for the UV380/RT3S and DM-1701
This version aims to fix keypad scan issues on some UV380/RT3S and hopefully also works on the DM-1701. Thanks to Colin G4EML for this fix.
It also changes the Calibration menu Frequency Adjust to show the value as +/- 127 instead of an arbitary number from 0 to 255
It also fixes rollover issues with numbers in this menu, and also fixes and internal issue which was causing the settings to be unncessarily marked as 'dirty' and needing to be saved

Hopefully this Beta can become the first Stable release if no bugs are found.

thank you
Re: UV380 + DM-1701 Beta 2023 03 08
Just flashed it in my MD-UV390 and everything seems to work just fine. Thank you so much!
BTW, this beta seems to still have the "click" noise in the menus w/eco mode. Once I fully understand the new code (I've played around with the GD77 sources, but I suppose this will be different), I'll try to see where it comes from and help solve it. However, I wouldn't even consider this as a bug, as normally the radio is never left in a menu unless you're changing something, and in the CH and VFO UIs the click doesn't happen. It's only something cosmetic and doesn't compromise any functionality at all.
That's great news! Can't wait to check it out. I suppose the IDE you're using for this version is SW4STM32 instead of MCUXpresso, right?

I must admit I forgot about the click bug. I did briefly look at the code to try to understand why the problem would happen in the menus and not the VFO or Channel screen, but supporting the DM-1701 and also processing bug fixes for the DCDM Rx and the DTMF + CTCSS (from Colin) took higher priority

RT-3S without GPS, updated and stable. No chance of returning to the original firmware. TKS team.

DCDM Rx always worked on the GD77 etc, but somehow some code got deleted from the UV380 version so that it didnt work.
DCDM Tx is unlikely ever to be supported because
1. DCDM is unncessary for ham radio, as it is a feature to allow 2 simplex radios on the same frequency on different TimeSlots, with or without a master reference base station for synchronisation.
This function is used by commercial operators becuase they pay per channel, and it is cheaper if they can use the same channel for 2 different communications.
On Ham radio we have a huge spectrum and can simply use different frequencies.
2. AFIK. DCDM is manufacturer specific , it is not part of the ETSI spec, and is covered by patents for the Motorola version
3. There is no documentation on how to configure the C6000 DMR chip for operation in this mode.

I agree, it’s not really necessary for ham radio. The only use would be for a single frequency repeater, and it’s my understanding that the RF chip can’t handle changing from Tx to Rx that quickly. I was asking out of curiosity.VK3KYY wrote: ↑Thu Mar 09, 2023 12:05 am1.

GD-77 RF chip does not seem to be capable of switching from Tx to Rx fast enough to handle SFR. The official programmers may know a way to make the RF chip work faster but there is no documentation about if this is possibleEA5JAQ wrote: ↑Thu Mar 09, 2023 12:23 amI agree, it’s not really necessary for ham radio.

MD-9600 may be capable of SFR but we did not have time to develop code to test this.
MD-2017 may also be able to support SFR becuase it seems to have 2 x AT1846S transcievers, but we don't know the internal connections
Re: UV380 + DM-1701 Beta 2023 03 08
Bringing up an old topic.
I am experimenting with a SFR on the ham band to see if it's feasible. The thought of a repeater with no duplexer running DMR is intriguing but in order to test range vs a conventional repeater means having radios that can do DCDM.
My MD UV-380, to my surprise, when I was messing around with the original software has the ability (supposedly) to do it, but can't under OpenGD77, so it doesn't appear to be any limitation in the radio.
So having it a working feature would be really nice--- and even better would be to have it transmit one slot but RX on the opposite, thus making the "user experience" of the SFR the same as a regular repeater.
Food for thought, perhaps it should have been its own topic but I did a search for DCDM and this is what I found.
