NOTE: THE RADIOS ARE REUSED FOR 9V1RMP REPEATER

This MMDVM project is something that I have wanted to do since I joined this hobby.

If you guys have an MMDVM Duplex Hotspot or repeater… and your Ailunce HD1 or any other radio is not allowed to transmit or say the repeater fail or give a long continuous beep tone, Here is what you need to do: 

Set your DMR TX Level higher than 50. Best to increase in 5 increments. For my setup, I have set it to 75.


The Project is Put in a Case and is ready to deploy as a hotspot.

Update 27 June 2022 

// This are for the GM338 radios that i have.

The RSSI File is configured as follows:
# This file maps the raw RSSI values to dBm values to send to the DMR network. Several data
# points should be entered, and the software will use those to work out the in-between values.
#
# The format of the file is:
# Raw RSSI Value dBm Value
#
#
# RSSI Default Values for MMDVM_HS

On 27 February 2023, I pre-programmed the Software to minimize programming on-site due to the limited time at the repeater site. Request that the Repeater Host forward these ports to the HamVoIP on the Pi. Port 32023 TCP for SSH Port 5038 TCP for Supermon management Port 4569 for AllStarLink Incoming Let's start!! Grab an SD Card and flash the SD Card with the latest software version.  Allstarlink version or HamVoIP version  . I used Balena Etcher on Windows 10. I used a 32GB SanDisk Ultra Class 10 card. For this Raspberry Pi, we will be using HamVoIP version 1.7-01. Plug your audio interface and ethernet cable into the Pi, The interface I will use is from Repeater Builder USB RIM - Alinco .   Now it is time to find the Pi on your network; I used Advanced IP Scanner and ...

13 August 2023: 9V1RMP UHF Repeater Maintenance Change log

Image
  Published on the 14 August 2023 at 1330 Hours UTC All Images and text cannot be reproduced without permission from 9V1FH / AI7GW, Fu Hang. On 13 August 2023, I went to the 9V1RMP Repeater Site to do maintenance and install the new Motorola transmitter and receiver as the old Icom FR6000 Finals blew. I arrived at the site at about 1500 hours when the scheduled time was 1500 hours. Warmly welcomed by the Repeater Host, 9V1BH, Victor, on-site. As the Repeater and AllStarLink node was already configured at my place and tested on a test frequency for 2 weeks, the whole unit was ready to plug and play. Still, it required port forwarding, confirmation that the links were set up correctly and no RFI when testing. While installing the new repeater, I requested the Repeater Host to forward three ports to the Pi. Port 32023 TCP for SSH  Port 5038 TCP for AllStarLink system Information and control Port 4569 UDP for AllStarLink Incoming Did some testing by connecting to 9V1RS AllStar Nod...
