We added a special message to the protocol. It should be sent by the server to repeaters. No response is required. Message format: RPTSBKN01234567. Where 01234567 is ID of repeater (hexadecimal string of 8 characters). BrandMeister supports handling of RSSI reports: Message format: RPTRSSI01234567:1-120.0. Instructions indicate using the STM32-DVM/MMDVM_HS - Raspberry Pi Hat (GPIO) modem choice. It works great in simplex mode, updated firmware and current pistar software. I have a few questions when using it in duplex mode. Instructions say turn on "Duplex Repeater (or Half Duplex on Hotspots)". When I do that, I assume I need a split in TX & RX ...patreon.com/M0FXBHAMRADIODIARY paypal.me/M0FXB paypal.me/M0FXBDouble timeslot in DMR mode, work as a mini Digital repeater.

Is there anything that has to be done via hardware? I understand if you want to decode the AMBE, using a chip is economically better because of patent. But I assume MMDVM repeater doesn't need to decode AMBE, it just passthrough the voice stream.

Longitudinal studies play a crucial role in understanding the dynamics and changes that occur over time. These studies often involve the collection of data at multiple time points,...The duplex boards have one immediate advantage over the simplex hotspots, which is that you can transmit even when your radio is in the middle of receiving. This means that you can easily unlink from a busy talkgroup even when the hams using the TG don't leave gaps between their transmissions. Another advantage of the duplex boards is that you ...

The K0USY Group 444.375 repeater in Lawrence, KS is a multi-mode digital and Analog FM repeater. This is the whole repeater, nothing has been omitted. There are no cables or devices hanging off the back of the MTR2000. To be fair, this article isn't just about the STM32-DVM-MTR2K, but this handy board from WA0EDA makes it even easier to do.

I'm interested in building a DMR repeater with a GP340 and I like the idea of using single frequency as'd save a diplexer and ideally a radio as well. No, you need a duplex hotspot for that. Most MMDVM's fake it. A real repeater can do it, but not an MMDVM. Just for clarity, I'm not talking about the hotspots (although it would be neat to use ...For a REPEATER install you need to load the FM firmware onto ur MMDVM repeater board.

Unlike Hotspots, the STM32 MMDVM Radio modem can scan mutliple modes very quickly and lock on the RF mode it hears. My other repeater scans for D-Star, DMR, and Fusion and decodes very quickly and reliably. Here is an image of my latest MMDVM repeater build, using the RB STM32-MMDVM modem and two FC-301D data radios.

GB7IT is our DMR repeater which is connected to the Brandmeister network. We are using a Yaesu DR-1X repeater with an MMDVM KI6ZUM radio pcb for raspberry pi board plugged into the rear 15w HD connector of the DR-1X.

I even tried a different radio thinking it might be the radio is not transmitting. Using a AT-D868UV I get the "repeater not found" message. Using a GD-77 it doesn't give me that message, but nothing seems to be happening. Also on the Zumspot board the only light that is on is the power light. During none of these tests did the PTT or the DMR ...Every MMDVM board has the potential to be calibrated slightly different due to the tolerances of components during assembly.
