I got the Pluto+ a couple months ago and was going to start on a next-generation repeater project that I have been discussing with N8GNJ and KA9Q but then started looking into some LinHT project development, and am currently busy with a few other projects that I should have wrapped up in a couple weeks. The Pluto+ is quite nice in that it can do 2 simultaneous full-duplex channels as well as wideband data and any conceivable data or voice mode. BTW there was another mention of USRP in [Radtel RT-880 Development](https://community.allstarlink.org/t/radtel-rt-880-development/23813/) , is that the Python library you’re using?

Re. the error you saw here’s what’s in [app\_rpt /channels/chan\_usrp.c](https://github.com/AllStarLink/app_rpt/blob/master/channels/chan_usrp.c):

```auto
		if (memcmp(bufhdrp->eye, "USRP", 4)) {
			ast_log(LOG_NOTICE, "Channel %s: Received packet from %s with invalid data\n", ...

```

Looks like it’s expecting the text “USRP” in the packet headers… If you wanted to debug further from the ASL side here are some notes on building ASL from source: [GitHub - davidgsd/app\_rpt at doc](https://github.com/davidgsd/app_rpt/tree/doc#recommended-pull-request-pr-process)
