Can a UDRC hat be used for FreeDV? FreeDV is a Digital Voice mode for HF radio. You can run FreeDV using a free GUI application for Windows, Linux and OSX that allows any SSB radio to be used for low

[…] It should work. It is actually on my TODO list to get my little Raspberry Pi going with FreeDV. At worst, we might need to tell it how to drive PTT, and that should not be a hard modification. Act

I'm going to try to compile the FreeDV code using Compass Linux, which runs on the Raspberry Pi and UDRC-II hat very well. It has the drivers for the UDRC-II board. The PTT line is handled by the UDRC

I currently have the the Raspbian Jessie port of FreeDV loaded on a RPi 3 and UDRC-II. I have not tested it yet to see if the processor can keep up. The UDRC shows up using ALSA in the configuration m

Indeed. That, or I wonder if we can do something with hamlib, since FreeDV integrates with that. Anyone know if hamlib supports UDRC PTT? It is actually on my TODO list to get armhf builds of FreeDV g

Hi, My name is David Lardizabal (HQ2DDL), I am located in San Pedro Sula, Honduras. I have a UDRC II sound card on a RPi 3+. I have used the set up for a high power hotspot simplex (5 watts), it has w

You can't have access point set to SIMPLEX. It should be set to GATEWAY in the software. The dstarrepeater repeater software will do the swapping of the RPT1 and RPT2, so that the UDRC software would

Hi Johnny, Thanks for the response I have made the change but it still remains the same only outgoing transmission, but no incoming pass from/to UDRC to the VHF radio.

Correction no incoming transmissions as well as outgoing in the GATEWAY setting.

Next I would check the wirings from UDRC to the icom 7000. I guess you are using the minidin 9600 baud connection to radio. I am not familiar with icom 7000, but may want to make sure it is set to 960

Hi Johnny, I do not think it is the cable because I checked using the icom 7000 as a hotspot earlier today and it worked okay. On the 9600 baud, I tripple checked because I have made that mistake on t

#udrc-ii #vhf

Yes. I believe if your icom repeater is set to a specific callsign, you will need to set the access point to the same, so your own callsign can not be in the settings of dstarrepeater and ircddb gatew
