Two issues with NXDN operation

I have found two issues I would like to find a resolve for. 1) In NXDN mode, a linked reflector seems to time out and become dropped at some point. I know DMR drops after 15 minutes, except for static talkgroups, but since NXDN only supports 1 at a time, I assumed it would stay connected. After it i...

Re: Unusual P25 Behiviors

I've exhausted the tools I have available. Utilizing a dummy load and a power meter/frequency counter (uncalibrated) I determined output power is expected on both high and low, and frequency is stable to 1kHz (the accuracy of my equipment). I can't tell if it's exactly on frequency, because its not ...

Re: Unusual P25 Behiviors

Frequency & stability are something I need to look into. I know I don't have the equipment necessary to check that, but I'll reach out to some friends that might. I can understand the scanning of modes, but the massive delay doesn't happen with other modes, and the repeater has every mode enabled.

Unusual P25 Behiviors

I'm new to P25, but this doesn't seem normal compared to other supported digital modes. I have a P25 HT, and it is programmed appropriately with the repeater/hotspot and the correct C4FM Astro personality. I have a hotspot, and access to a multi-mode repeater based on the STM32 hardware and pistar s...

Re: MMDVM Dual Hat Duplex Setup

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 frequency? Yes. I tried the same frequency, and a 0.3MHz split. Neither work. With the 0.3MHz split, It reco...

MMDVM Dual Hat Duplex Setup

So, I decided to build a second hotspot and split D-Star from DMR now that I have started using both for a while. I decided to use a duplex hat since the price difference and availability is about the same. It is installed on a RPi3+B. I have it tuned up as s simplex node (according to the band plan...
