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

Ok, thanks. I happen to have some Overp Earth boards, OMAP 3503
Application Processor with ARM Cortex-A8 CPU, do you think these
will handle the job? (runnin at 600 MHz). They say it makes up 1200

It's

unfortunately it's only a TI TPS65950 which has only an audio codec,
the ADC doing 48kHz max.
That's still usable, you could for instance use a DRM frontend
like the pappradio

Greetings to all members.
I would like to purchase the following parts for the Austron 2000C
LORAN-C receiver:
-ASSEMBLY PCB ASSY GRP DIVIDER, ASSY NO 10397137;
-ASSEMBLY PCB ASSY PHASE CODE, ASSY NO 10396936.
The above parts could eventually have been produced by Tracor, Inc.

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:
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.

I have looked at that earlier, but it does not look like it is
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:

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
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.

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
