Special Support for the Elektor SDR Shield - aka SDR Reloaded - 7/2016

The G8JCFSDR is an SDR which uses RF front-end hardware to down-convert RF frequencies into the 0~24KHz range accepted by most PC soundcards. The PC reads in the soundcard signal and carries out all of the filtering, demodulation, AGC, and notch filtering in software rather than hardware as would be the case in a traditional receiver. Because the receiver is all software, there are things you can do which would be almost impossible in h/w.

This is Peter Carnegie's (G8JCF) Software Defined Radio.

The G8JCFSDR works with very many SDR H/W front-ends, eg FiFiSDR, Pappradio V1 & V2, PMSDR, Elektor SDR, DRT1, DRB30, DRB32, Soft66AD(M), Lazy Dog LD1, EXTIO_*.DLL supported H/W

Special support has been built in for Burkhard Kainka's ELEKTOR 3/2004, 5/2007, 7/2016, Ulf Schneider's DRT1, and the NTI DRB30/32, & the PappradioV1 hardware down-converters. The G8JCFSDR will also work with home-brew IQ and NON-IQ Receivers using AD9835/AD9850/AD9851/AD9951 DDS Chips, and with CY27EE16 PLL generators. Full USB support using FTDI US232C RS232/USB converters is supported with full high-speed Bit-Bang mode.

Burkhard Kainka's ELEKTOR 7/2016 aka SDR Reloaded H/W is available from Elektor for about EUR 35 - the best Elektor SDR so far.
Ulf Schneider's front-end H/W is unfortunately NO LONGER available from sat-schneider .
Rudolf Ille's excellent fully boxed down-converter, the DRB30 and the even better DRB32 is available from NTI DRB30 for about EUR 400-00

If you come across a DRT1 secondhand, snap it up !! The DRT1is a very high performance 0~30MHz to 45MHz IF to 12KHz final IF down-converter. The NTI DRB30/32 are very similar in performance and come in a nice enclosure, again if you come across a secondhand unit, snap it up !!

Yahoo has shut down its Yahoo GROUPS service for all practical purposes, so we have migrated to G8JCFSDR group over at GROUPS.IO.  I hope that G8JCFSDR users will sign up to the G8JCFSDR@Groups.io please.
