This is the source code of ZUMspot/MMDVM_HS firmware for personal hotspots (ADF7021 version of the MMDVM firmware), based on Jonathan G4KLX's MMDVM software. This firmware supports D-Star, DMR, System Fusion, P25 and NXDN digital voice modes and POCSAG 1200 pager protocol.This is a short manual for setting up MMDVM hotspot or repeater using Kavkaz SD card image created by Igor UA6HJQ. STEP 1. HARDWARE. You need to purchase next components: - Raspberry PI3. - 8GB or 16GB Class10 MicroSD card. - Arduino DUE. - Shield for Arduino DUE, for example designed and assembled by ES1BIS.The second option is to swap out the D-Star hardware with an MMDVM repeater setup in D-Star mode. Of the 2 option, this is probably the best because it would allow people to change reflectors and even use the other reflector types, not just the old REFxxxx reflectors. Also, it would eliminate the convoluted hardcoded network configuration that ...Important update ,from firmware v1.4.12 Frequency restrictions to avoid satellite interference.

You can use an MMDVM hotspot if you don’t have a digital repeater nearby or simply want some other options. Basically, hotspots are your own personal digital voice repeater and gateway. A personal, low-power hotspot is a combination of hardware, firmware, and software that lets an amateur radio operator with an Internet connection link ...After some time in pratical use Im extremly satisfied with the performance of the two repeaters. The Project: I got hold of two TB7100 Repeaters which I decide to use as dualmode DMR/D-star repeaters. I found some useful info from florian DF2ET about interfacing the TB7100 to MMDVM at the brandmeister Wiki.

When using a repeater/modem board attached to an appropriate FM repeater/radio, it may be necessary to "de-tune" the repeater/radio slightly, most commercial grade equipment operating within a 12.5khz channel may impose a strict 2.5khz (and no greater) maximum analog FM deviation, this is well below what is required for good digital operation. 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).

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.Specifications. The MMDVM-Pi board is designed for repeater and high power hotspot applications – connects to user supplied Raspberry Pi board and radio(s) Utilizes a high performance 32bit ARM processor (STM32F722) running at 180Mhz (Room for future upgrades) Fifth generation analog filter design that provides an extremely low BER …We specialize in producing hotspots and digital mode repeaters - such as our best-selling ZUMspot and MMDVM-Pi products.

The STM32-DVM-MTR2K will saturate the MMDVM ADC input at signals much stronger than -30dBm. That's ok, I did that on purpose in order to keep the signal level at the low end up a little higher in order to improve ADC resolution for weaker signals.
