The STM32 has an on-board microcomputer, so there is no need for a separate Arduino or other processor board. This board, plus a platform running MMDVMHost is all that is required.Use MMDVM on a repeater with Raspberry PI3, Arduino and NTH radio card. On the raspberry I mounted a UTAH SD but I have the problem that when I restart the raspberry, the MMDVMHost does not start automatically .. By launching MMDVMHost instead manually, it works regularly.Dec 12, 2019 · After setting up the MMDVM duplex hotspot board, it is necessary to adjust the transmit and receive offsets in the MMDVMHost expert editor section. Basically this corrects the transmit (TX) and receive (RX) frequency of the board, if they’re not on frequency. This is the BER 0.4% when no setting RX/TX offset.

Re: Building your own MMDVM repeater. by KA9UCE » Sun Dec 16, 2018 2:07 am. Hello.... I am thinking about programming a couple of Maxtracs for use with MMDVM, and my Pi-Star ZUM radio.

First I compared the sample TKR 850 model 2's programming with the KPG 66 I have ...

DMRDelay is how you tell MMDVM about this delay so that the subscriber can properly synchronize to the repeater. It appears the XPR8400 has a similar receive architecture. I re-tested D-STAR and got the RX pots optimized. Then testing DMR, I started with DMRdelay of 165 and walked down to 1 55.Dec 22, 2020 · For preview, more settings guide please follow my YouTube , I will update again.MCS2000 pinout sane as GM1200.The MMDVM repeater board and cable, obtain from...

DATA SPEED = 9600 bps and use 6-pin Mini DIN cable as specified by RepeaterBuilder.org (pin 4 "PR9" is audio output before discriminator). From MMDVM set TXInvert=0 and RXInvert=1. Note that TX audio gain must be set quite high for DMR to operate properly.The hotspot repeater name of ‘KK6DCT B’ needed to be set EXACTLY in the repeater name setting for the DV memory setting on the radio, otherwise keying up the radio wouldn’t even appear on the mmdvm status page and it seems the transmissions are completely ignored by the hotspot (presumably because it’s not hearing traffic matching it ...Apr 28, 2021 ... patreon.com/M0FXBHAMRADIODIARY https://www.pistar.uk/ https://www.facebook.com/groups/291263039350674/ http://pi-star.local/ ...

This repeater is extremely well built, rated 100% duty cycle at full power. Initially I used a Repeater Builder STM32-DVM MMDVM modem board. This board and associated software on the Pi take over as the repeater controller.

and a MMDVM board is a digital only device. on the flip side you can use AllStar on GMRS to link repeaters together and I suppose simplex nodes as well (no repeaters allowed on MURS) there is plenty of GMRS linking going on via AllStar. but you must run it on a private network as you cant cross GMRS and Amateur services.

MMDVM hardware and software is at the core of most digital mode hotspots on the market.
