Hi,
So 12kHz bandwidth = 6kHz Audio, will do.

I’d like to see variable badwidth on AM to 12 kHz. 4, 5, even 6 sounds tinny on local strong stations. 4 is fine for DX but not for armchair listening.

Re FM (Broadcast) well 15Khz is the upper audio limit (due to the 19Khz pilot tone filtering)
Due to channel spacing (9Khz in Europe - 10Khz in US ?) 4.5/ 5Khz audio max. But on SW where channel spacing is less , the same max audio frequency still tends to be applied, interference being minimised by not using the channel next to another strong signal !
DAB uses 48 or 24Khz sampling and so can in theory carry up to 22Khz or 11Khz
I can find out about DRM – but not too sure at present

Have the Frequency Spectrum Display in sync with the audio, it is delayed about a second from what comes out the speaker.

Re: Scheduled Recordings
Mark \(G4PCS\) <g4pcs@...>
Hi Simon, Can I request that a scheduled recording leaves the SDR running when the recording period ends, or at least an option is provided for this? A more general alternative might be to restore the SDR to the state it was in before the scheduled recording started, or perhaps to a pre-defined user state. A rather more dangerous request... How about an option to delete all files in the record file destination directory before recording starts, perhaps per-schedule rather than as a global setting? Regards, Mark G4PCS

Re: Scheduled Recordings
EB4APL <eb4apl@...>
Simon, thaks to the SDR panadapters I see that MW stations uses up to
10 KHz (20 KHz AM spectrum). I've seen some powerful HF stations
occuping betwenn 16-20 Khz.
In FM broadcasting the standard is 300 KHz channel spectrum, if my memory doesn´t fails me. The audio BW is around 12-15 Khz. Probably there are some broadcast engineers here that can speak more properly than me about the standards and how well they are followed. 73 de Ignacio, EB4APL--------------------------------------------------- Simon HB9DRV wrote:

Re: Scheduled Recordings

Hi,
All understood:
· At the moment the filename is predefined by me, the folder can be user-defined and if it doesn't exist then there's a fall-back folder. · File chaining - there's a maximum .WAV file size of 2GB, also using many smaller files is good in case of a computer crash, software crash or disk corruption :) · 2MHz is now working @ 16 bit sample rate: http://www.sdr-radio.com/News/tabid/185/EntryId/41/SDR-IP-and-2MHz-Sample-Rate.aspx · I am working on ICOM integration, with luck available end of next week.

Simon,
Excellent work!
Perhaps this is already done and just not obvious from your teaser screenshots but having the ability to specify filename, location and optionally, frequency and time-stamping would be great. Ideally there would be no need for file chaining (as SVue requires today unless you mod the ini).
Also, since I use scheduled recordings regularly with SVue and my SDR-IP it would be of great interest to also have 2 MHz BW capability (at least for IQ local network capture) and of course external radio support for IC-R9500 and R8500).
That's all I can think of right now.
