It's blue in color, bought by me a few weeks ago from china. It says "NEW GEN. RTL2832" and under that "R828D & SDR". It has a small 800mhz antenna with it. The connector for the antenna is tiny and plugs(not screws) into the dongle. The "lsusb" shows "Bus 002 Device 002: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T"

I have some of those too. Mine were ordered with TCXO and the max ppm error I've experienced with any of them has been +/- 2.0.
Glad you got it working however.

If the terminal identifies the calls as "Encrypted" it's because the alg_id is coming through as something other than 0x80 which means they really are un-monitorable without the proper keys and software to decrypt.

It is illegal here in Canada to decrypt encrypted traffic. Maybe there are some exceptions for POLICE and FIRE or EMS, that I do not know about. Would be nice to be able to match the talkgroup IDs with the agencies involved though.

I'm up to 18 unidentified talk groups already, so far everything is encrypted.
