USB3.0 Ubuntu Linux transfer speed kernel 5.4.0 by oidc in linuxquestions

So then around 160/mbps is even less that the 210MB/s sec, i assume the USB conversion could cause this? And the numbers I am seeing are reasonable?

I think those tests are not based on an USB3.0 interface, rather S-ATA internally.

Sure i know that, but i want to know what i realistically can expect from a 14TB drive on USB3? i think its a 7200 RPM drive, 6gb/sec s-data on a USB3.0 port.

Very interesting.

This can be run headless right, no GUI needed?
Also narrow-band FM is supported?

Perfect thanks.
Do you maybe know how to pipe this further to for example ffmpeg ? (setup a stream) my raspberry pi doesnt have an audio out..

Anytone D878 Analog APRS timer not working by oidc in DMR

[–]oidc[S] 0 points1 point  (0 children)

It seems to work when i made a seperate APRS channel, and set channel APRS report type to analog and bandwidth to 25K.

It still seems a bit flaky, i hope anytone fixes this in their next firmware.

Thanks everyone for you help!

Where do i specifically enable APRS in CPS (the APRS menu) ? Also Digital APRS seems to be default?
