[IRCA] Fwd: [sdr-radio-com] SDR Receiver ELAD-FDM-S2: Test drive with a 6MHz HF file!





For those interested in the Elad FDM-S2, from the sdr-radio list....and no, I haven't tried it yet. Posted by "Nils Schiffhauer" <DK8OK@xxxxxxx>

best wishes,

Nick



Hi - to test and to try out receivers had been a difficult animal. With
SDRs, their freely available software and some HF-files all has changed: Do
it yourself!

I had prepared such a test drive with a 6 MHz wide HF file (actually three,
chained automatically by the software), centered around 10 MHz, just 20
minutes after local sunset at 17:00 UTC on a 83 m long piece of wire with
ELAD's FDM-SW2.

A screenshot of the whole recording as sonagram (blow it up to 100% - woow!)
can be downloaded at:
<http://sdr.eladit.com/Sample%20wav-files/DK8OK/10MHzCF_5MHzWidth_1700UTC/10
mhzcf_131s.png>
It has been made with Simon Brown's "SDR-RADIO.COM".

Then you may view a video with some examples from this file (broadcast as
well as utility) at:
<http://sdr.eladit.com/Sample%20wav-files/DK8OK/Video/>

To actually take a test drive, you have first to download the software
FDM-SW2 itself; it's free:
<http://sdr.eladit.com/FDM-sw2%20Software/FDM-SW2_complete_setup_sw_1_03Beta
10/>

Install it.

Then download the three HF (WAV) files from this folder:
<http://sdr.eladit.com/Sample%20wav-files/DK8OK/10MHzCF_5MHzWidth_1700UTC/>

This may take a while, for they weigh 4 GB.

Copy them into the "Recordings" folder of FDM-SW2 software.

Start software FDM-SW2, click onto "Offline", then into "File", and choose
the first WAV-file. Start playing. During playing, they are automatically
chained.
As the recording in wide, but short, you may activate the loop function.
Now try out the receiver/file, as you like - it's a feeling really like
"live"!

Hopefully, your PC accepts these big files, and is not stuttering. It all
works fluently on a PC, state-of-the-art. It is planned to upload also
smaller files.

Critics & comments welcomed!
