No problem, I can run test whenever you want.

Yes, It works as well as the FCD. I can't say it work the same, since sometimes the FCD picks up AIS messages the RTL doesn't, and sometimes it is exactly the opposite.

The default settings for UHD are 256Khz sampling with decimation
filter 4, with this change, the decimation is one when using FCD
(96KHz fixed frequency) and 16 for RTL when used at 1.024MHz (this
was the minimum working frequency for me).
Or maybe would you prefer to allow the user to set it manually, and
use this technique as a fall back only.

Please let me know what you guys think.

Thx,
Chris
