Had I known a trip to EU would have been in order. Going for a ham radio vacation anyway. 8R satellite. The radio (B210) runs with either of the I7 laptops that are here. As you point out, making sure that the bus speed and devices are compatible is key. The B210 is a "development board" so to

I could make a raw capture with a 14bit Perseus or 16bit Elad FDM-S2 and a good active receiving antenna, but the station I can receive very strong is Sylt here in Germany. As far as I know this station will not shut down... 73 Joerg, DL2NI Am 19.12.2015 um 12:25 schrieb Magnus Danielson: > Hi

The Perseus has a higher dynamic range than the Elad, if that matters. Rob, NC0B Sent from my iPad > On Dec 19, 2015, at 1:30 PM, "Jörg Logemann" wrote: > > > > I could make a raw capture with a 14bit Perseus or 16bit Elad FDM-S2 and > a good active receiving

Would you be able to record what you want via the online web SDR at the Twente University? http://websdr.ewi.utwente.nl:8901/ cheers, Graham ve3gtc On 2015-12-19 10:35, Poul-Henning Kamp wrote: It doesn't seem like my old hack to record VLF spectrum works anymore. Are there anybody in

That's what I said. 61.44MS/s. This thing is a fire hose. Saturate a usb 3.1 without much problem. Gotta love computing! On Sat, Dec 19, 2015 at 5:01 PM, Poul-Henning Kamp wrote: > > In message <5675ac3c.8020...@aei.ca>, Graham writes: > >>Would you be able to

The Tektronix RSA306 9 kHz - 6.2 GHz RF signal analyzer samples the IF at 112 MS/s (14 bit A/D), so it streams data over USB 3 at 224 MB/sec. A PC with an I7 (or even a good I5) and a modern solid state hard drive can keep up with this streaming data and store hundreds of GB of contiguous

It doesn't seem like my old hack to record VLF spectrum works anymore. Are there anybody in Europe who can do a raw capture of the VLF spectrum over new years eve to capture the last LORAN-C transmissions as a historical document ? Ideally a 1 MSPS ADC directly on a good antenna, but failing
