[time-nuts] Ideas for a long-wave receiver sought

Hi I want to build a small, cheap, yet precise long-wave receiver which can be tuned from the computer in the 2KHz - 200 KHz range (the intended use is to receive various time signal stations). Does a chip for such a receiver exist? Should I take the SDR route? I designed a DCF77 receivers

Hi Marc: The SDR-IQ has the ability to record everything between 500 Hz and 190 kHz when used with a fast enough PC. This is the best of the SDR series for use below 200 kHz. It can be used with SpectraVue or Winrad. Works with I2PHD WINRAD, SM5BSZ LINRAD, HOKA and DRM software. See:

[time-nuts] SDR-IP with 10 MHz Cesium and 1 PPS Input

Hi: RF Space is developing the SDR-IP (Internet Protocol) receiver that has options for an external 10 MHz Cesium reference as well as 1 PPS input to allow multiple receivers to work as RADAR sets (using FM radio broadcast transmitters) or for radio astronomy.

Hi Poul: The SDR-IQ has holes in the PCB for an SMA jack and there's a jumper/resistor used to select either the on board 66 MHz crystal oscillator or the external source. See: http://www.prc68.com/I/Bats.shtml#SDRIQ Have Fun, Brooke Clarke http://www.prc68.com Poul-Henning Kamp wrote: In

200kHz is a bit tricky for the top end.. That probably puts the standard music recording A/D out of the picture (although they have very high performance A/Ds in them, and because of large production volume, they're relatively inexpensive). Almost any PC these days has enough processor to take

[time-nuts] ARRL FMT - addendum

A couple of details that might help you avoid confusion in next weeks ARRL FMT; 1.) The CW ID transmissions will be on the carrier frequency. 2.) Tone transmissions will be on the Lower Side Band. -Mike- WA6ZTY ___ time-nuts mailing list --

Re: [time-nuts] Ideas for a long-wave receiver sought

It's not necessarily inexpensive, but here's one data point: an EVAL-AD7760 board is $150, and a Nexys2 FPGA board is $129. This combination can acquire DC-1 MHz with 100 dB SNR and 120 dB SFDR. There is no need for a hardware or FPGA-based DDC, as any modern PC can do host-based processing at
