Welcome to BI7JTA'Wiki for MMDVM.

Begin December 1, 2019, I will continue update this WIKI page instead of Google blog, I am working on MMDVM just for my hobby, I am happy to share my knowledge and resources about MMDVM open source project.

Motorola Hytera big offset adjustment

Attention: Motorola ,Hytera DMR radios, as my experiences, there's always a big offset, And decoding is sensitive to frequency offset requirements (If you use AnyTone878UV, TYT MD380, or other China DMR radio, will better to decode DMR signal, and not big offset.

But no problem, you can adjust it easy, it is not he MMDVM problem, remember!

Very Important Process: Calibration Frequency Offset

 How to calibrate it? the frequency is shifted too far?
 1, Calibrate your RTL-SDR frequency, Config --> PPM, Send a FM signal and received by your RTL-SDR SDR#
 2, Adjust the PPM , let your RTL-SDR frequency same as your handset Radio,
 3, Send the same frequency from your GM338, GM340 repeater TX/RX radio , find out the offset, compare your Handset radio.
 4, Calibrate your GM338, GM340 repeater TX/RX radio frequency (Hz), use Professional software, if you can't find it, jump to 5th
 5, Write your handset radio frequency , suit your repeater radio.
Frequency Offset Calibrate software

    • You can also use RTL-SDR, SDRPlay, if you have adjustment your SDR PPM (frequency offset)

RSP-SpectrumAnalyser.png


RSP-SpectrumAnalyser-2.75KHz.png

Repeater Bandwidth for test

Repeater radios bandwidth recommend order: 25KHz >> 20KHz >> 12.5KHz(Some radio will get big BER if use 12.5KHz)
Your DMR/C4FM/P25/DSTAR/NXDN radio decode bandwidth (MMDVM TX):12.5KHz,

You will find it will easy to decode your radio RF signal in low BER%, but if your radio have big frequency offset, it will hard to decode voice and data in your Digital radio.
So Calibration Frequency Offset is very necessary , especially in old GM300 and Motorola digital radio.

In particular: For Motorola, Hytera DMR devices, frequency offset causes Repeater, Broken QSO to fail to open.

How to adjust Frequency offset? 1, Programming your DMR radio, 2, Programming your Repeater radio.

eg.

Adjust Motorola XPR4550 DMR radio, possible offset -500Hz, -400Hz, ....400Hz, 500Hz .... , till the BER% become low and perfect to QSO , listening

NOTE: FM Mode just work in Motorola GM338 GM340, GMxx,CDM1250, CDM1550 Serial now, NOT work in YAESU ,ICOM, KENWOOD.

In New firmware, you have to use new MMDVMHost(Pi-Star OS)

OS requirement
 Pi-Star for Repeater V3F4 New Firmware
 2024.1.25 
 If you use official PI-STAR (MW0MWZ), in order to detect the new V3F4 repeater firmware, you need to updete && upgrade your PI-STAR to v4.2.0
 Download the new IMG: https://www.pistar.uk/beta/
 Known issues:
 1, If you are using 460800bps the New FM network(MMDVM repeater V3F4), you must to add the follow settings to your

OS requirement

In New firmware, you have to use new MMDVMHost(Pi-Star OS)

 2024.1.25 
 If you use official PI-STAR (MW0MWZ), in order to detect the new V3F4 repeater firmware, you need to updete && upgrade your PI-STAR to v4.2.0
 Download the new IMG: https://www.pistar.uk/beta/

If still can not flash successful, you can try the follow methods:

Step_1, Plug out 5V2A Power supply,
Step_2, Short BOOTO and 3.3V Pins, then Power ON, let Repeater enter Recovery Mode, PWR, ACT, COS, DMR, POC light.
Step_3, execute ./v3f4_12MHz_flash.sh

(3) ST-Link tools

Risky operation, Caution, do not short circuit +5V, +3.3V, you need to be familiar with the use of ST-LINK.

How to Debug RX and TX

Debug TX and RX standalone, take DMR for example, first write 9 group contact to your DMR receive Talk group list , decode debug data.

SDR# lite (Old version just for view the spectrum) https://www.bi7jta.org/files/RTL-SDR/

RTL-SDR V1 , install Driver in Windows7/Windows10 (not test in Windows11)

RTL-SDR V4, suggest use SDR++ https://www.bi7jta.org/files/RTL-SDR/V4/

NOTE: FIRST YOU GOT THE BOARD ,KEEP THIS POT DEFAULT! The purpose is make repeater radio side generate a best digital spectrum. If you not have RTL-SDR,SDR#,Spectrum Analysis meter(such as CMU200), I not suggest to turn TX Potentiometer.

Adjust RX Level with MMDVMCal

The situation must adjust RXLevel

Turn the RX pot clockwise until the CLIP LED turns off

RXLevel-overflow.png

BER too high possible cause by RXLevel
 Attention: BER too high also possible cause by Repeater frequency (such as offset 500Hz, 1KHz, not control in Pi-Star)

NOTE: FIRST WHEN YOU GOT THE BOARD ,KEEP THIS POT DEFAULT! DO NOT ADJUST THE RV2 POT ON THE BOARD, UNLESS YOU HAVE RESEARCH ENOUGH KNOWNAGE ABOUT MMDVM PROJECT.

The purpose is make repeater radio generate side receive a best digital spectrum. If your BER% verylow ( less than 0.5), I not suggest to trun RX Potentiometer.

Hight BER% also cause by the BIG OFFSET of your REPEATER RADIO , or your Digital RADIO, consider this reason first.

To get the best value for the RXLevel, enter SSH mode

Set Static Talkgroups

First, you must Register BM network https://brandmeister.network/?page=register  ,then wait the BM WebMaster review, about 1 day.
Change hotspot default password(Must do). https://brandmeister.network/?page=profile

Second, set static talkgroup for your DMRID , support ESSID (the two number tail of your DMRID)

NOTE: The static talkgroup is closely related to your hotspot ESSID and BM Server!


Method 1: Config online

Explain:

rep-edit: Duplex repeater mode , can use TS1,TS2 the same time.

hotspot-edit: Simplex mode, just can use TS2,

460072322: 4600723 is my DMRID, 22 is my duplex hotspot ESSID, corresponding to my hotspot DMR ESSID item
