Screenshot of IQ Data Files
Why are the screenshots labelled by the *date of the screenshot*, rather by the *date of the received wav-file*?
Is it possible to get an automatic label based on the actual wave-file

Re: W-FM [1 Attachment]
Thank you for your maxhold plot, Pieter.
That was wide!
For a moment I thought that in the U.S. you had the FCC taking care that nobody would be wider than just the need of Stereo FM. Wich is exactly

Antenna Switching - Remote
Hi All,
I ordered two Velleman DM110 which I will support in the remote server. You have unlimited switching options etc.
Paul M0EYT is responsible for this decision.

Re: W-FM
Hi,
I spent last night looking at the software needed for decoding W-FM:
· Mono,
· Stereo,
· RDS.
Mono’s OK (not as simple as Ham FM but – simple), Stereo

Re: W-FM
Hi Russ,
Thanks for the US-based explanation. One reason for adding W-FM, Stereo and RDS (assuming US has the same RDS as Europe) is that with RDS the SDR can be used for detecting sporadic-E.

Re: W-FM
Jose,
You are right about the broadcast FM stations being over 200 KHz wide. In the US the stations can be up to about 400 KHz wide with the IBOC digital carriers. If you look at FM

Re: W-FM
Russ,
Just thinking about it...
Take your spectrum analyzer and select max-hold while at any FM station in your area. You can see easily how wide it is. In my area they are wide!

Re: W-FM
Yes, everybody knows that our FM is +/5KHz deviation and 2.5 being the narrow mode.
No secret either that AM station channels are every 10KHz in the U.S. and 9KHz in Europe. Right!
Nice to find a

Well, having worked as a broadcast engineer in the U.S. for nearly the last 30 years, all I can say is... HUH?!?!?� I have no idea what Jose's been smokin', but it must be REALLY good. ;-)

Re: W-FM
Don't expect stellar performance from the Dongle on Broadcast FM. It can only "read" an 80 Khz wide swath, and broadcast FM is 150 KHz wide. It'll work, but it won't sound pleasant at all.

Re: Video Demonstration of SDR-Radio with LD-1B Front-End Hardware
Good videos, Peter- thanks. I am seeing two issues (for what it's worth) when I try to decode:
- My decode window Freq is always off from the console window
- When console windows are booming in,

Re: W-FM
Hi,
75KHz is the nominal frequency deviation of a FM mono broadcast transmission, but now all of them are using stereo mode, adding two 38KHz sub-carriers. Mode is called 256-f3 because
