Re: W-FM
Hello, good people!

1st. Maybe It should be taken into account that pre-emphasis is 50us in the U.S. and 75us in Europe.
2nd. Since I got the impression that things

Dear Simon,
When implementing RDS decoding please remember to decode PI code too. It is faster to read than PS ant TXT and helps a lot to identify stations as a little stronger signal comes in during

I have noticed lately I cannot keep a connection if I am on my laptop with my wireless data card. I am on the Sprint network and usually have reliable coverage. This seems to have started with build

Re: Screenshot of IQ Data Files
Hi,
why not give a user's choice configuration ?
I mean .. setting a configuration variables, like %date %time %frequency .. or %d %t %f etc.
Does it make sense ?

This way all screenshots will be sorted in a logical way. And you can easily look up same frequency for a sequence of

Hi,
Nice idea J - if you want an automatic label just give me an example please.

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.

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
