From Dave G3YMC The RTTY signal which has reappeared on or around 137kHz is the self same signal we were discussing in January and at various other times. It appears for a few days at a time and then

For anyone who built the PIC based DSP interface (April 1997 RadCom) you have suitable recording hardware to hand. Just feed the AGC voltage conditioned to 0 - 5 Volts directly to the PIC input pin -
Hello Rik and others. A selective voltmeter can be built using a gyrator. If you have "The LF Experimenters Source Book" (RSGB), take a look at the gyrator tuned VLF receiver on page 3.7. The gyrator
On a similar subject, it would be really useful to be able to plot signal strength against time (say, 24 hours) using a computer - for Another approach, possible with some receviers, is John Rabson (
If there is some way in which the PSK31 baud rate of approx 31.6 can be converted to MS25 for use with the DeCarle COHERENT program, we have the best two worlds. The narrow bandwidth of PSK31 and err
Another approach, possible with some receviers, is John Rabson (G3PAI)'s logging software, referred to in a previous reflector email ;-) I have written some simple software to control the Lowe HF250
