History

2021-08-09: I re-created this page on my self-hosted web server.

2013-01-20: testing the device. The antenna connector snaps in place with a very audible click, which is nice. There is a plastic cover over the usb plug, easily removed. When I connect the device to my FreeBSD workstation, currently running:

tingo@kg-v2$ uname -a
FreeBSD kg-v2.kg4.no 8.3-STABLE FreeBSD 8.3-STABLE #6: Fri Apr 27 23:50:55 CEST 2012     root@kg-v2.kg4.no:/usr/obj/usr/src/sys/GENERIC  amd64

a blue LED lights up, and I get this in /var/log/messages:

that's all so far.

2013-01-19: the package arrived, delivered straight into my mailbox. Nice!

2013-01-10: I ordered a Newsky TV28T v2 usb DVB-T & RTL-SDR receiver from eBay (seller NooElec) for USD 20.45 shipping included. Contents: dongle, antenna, remote control.
