Ingrid gibt mal folgendes vom Entwickler weiter, der Preis beträgt 480 US-$, und er zieht (nur) aus der USB-Buchse Strom. Die Phasengeschichte ist "the next big thing": The in-depth info about what the design looks like is at my blog, http://uvb-76.net/p/sdr-mk15-andrus.html (the schematic there is 1 rev old, the clock for current units is actually 2ppm TCXO). Basically, it is a dual RF frontend diversity receiver what is currently running from 5kHz to 30MHz and gives frequency span up to 450kHz in single-channel mode and 232kHz in dual. At some point the firmware will support IF up to 600+ kHz, but there's some black magic what has to be mastered beforehand. Works over USB and 100Mbit ethernet. I have been trying to keep both, the schematic and software open, so whoever wants to tweak or add something, can freely do so. Diversity mathematics (precise phase shift between channels etc.) is handled inside the radio, so you can do some noise cancelling and rx beam-forming (although getting it right is painful task, but once you get the noise canceling really working with correct phase and signal level, it will make all the effort worthwhile! (until OTHER NEIGHBOR switches on its halogen lights and whole process has to be re-done ..) :)) It does work as two independent receivers as well tho (has two ADC-s, two downconverters etc.), whatever its good for. 73 Nils -----Ursprüngliche Nachricht----- Von: owner-liste@xxxxxxx [mailto:owner-liste@xxxxxxx] Im Auftrag von Nils Schiffhauer Gesendet: Freitag, 7.

Moin, moin - unter http://www.ebay.com/itm/SDR-MK1-5-Radio-Andrus-Shortwave-Receiver-Network-In terface-/260937960489 wird ein kleiner SDR-Receiver bis 30 MHz angeboten. Kennt den wer? 73 Nils -- ----------------------------------------------------------------------- Diese Mail wurde ueber die A-DX Mailing-Liste gesendet.
