I'm using an old Motorola R100 repeater. It's got the DCS option that can not be turned off. I'm running it on a Pi3B, and usbradio and full duplex with no issues, and fixing to add a 2m node to it, on simplex, with the antenna on top of the db-413 who's base is at 50'. It is the setup I had at my previous residence sans the rpi3b. Gonna be interesting. 73 = Best Regards, W5OMR / 29655 On Sun, May 5, 2019, 20:41 Kevin Custer <kuggie@kuggie.com> wrote:
Keith,
I've run usbradio on many Raspberry Pi 3's without issue. The 3B+ works fine with 2 nodes on usbradio, but I don't really recommend it. I also don't recommend a CM119B based radio adapter for usbradio deployments for several reasons.

I'm wondering if this is a realistic configuration for a simplex node:
RPi3 with DMK URI connected to the 9600 audio in and out signals of an Alinco DR-135T. I want to be able to use CTCSS so that random signals don't get bridged to connected nodes.
My concern is that with the above configuration, the CTCSS decode in the radio is bypassed. Consequently, CTCSS decode needs to be done via usbradio since simpleusb does not have this capability. However, I keep hearing that usbradio is not handled well with an RPi and yields less than ideal audio quality.
So all of the above implies that I either use a higher performance node PC or continue to use the RPi, switch to the 2400 audio in and out signals (so that the Alinco can handle the CTCSS) and use simpleusb.
Opinions?
Thanks,
