I have a rtl_sdr.com RTL2832U R820T2 dongle. It works with HDSDR and SDRSHARP programs.

Using win10 64 BIT 10.0.17134.345 and GNURadio 3.7.13.4/V1.5

Windows reports VID_0BDA, PID_2838

When I run GNUradio, I get [R82XX] PLL not locked!

When I open the GNUradio command prompt and run rtl_test -t, I get this:

At this page, https://osmocom.org/projects/rtl-sdr/wiki/Rtl-sdr shows this table :

VID PID tuner device name

0x0bda 0x2832 all of them Generic RTL2832U (e.g. hama nano)

0x0bda 0x2838 E4000 ezcap USB 2.0 DVB-T/DAB/FM dongle

Is it possible RTL_TEST is looking for a E4000 because of it's dongle's screwy PID, even though it sees a R820T. If not, why is it not working?

thanks.
