Idid ask for this some time ago, and Richard sent me the sources for an older version of the code, explaining that it was actually a hard problem, but if I wanted to have a go etc... The issue is tha
Actually you don't need full blown specrogram to start up on a timer you just need a program that starts up on a timer and captures a .wav file, which you can then feed into spectrogram at your leasu
Alan re recording .wav files (to feed into spectrogram), try http://www.nch.com.au/action/index.html It seems to be a wav recorder that you can set up on a timer. I have not tried it yet, but it look
There is a good analysis of the CFA ("Crossed Field Antenna") that has been written up by Prof. Jefferies at University of Surrey which he has posted on the web at http://www.ee.surrey.ac.uk/Personal
A friend of mine wants to put up a vertical in his back garden (actually to operate on 160m), and is thinking of using a met balloon to hold it aloft. I know that there has been some experience on th
For some time I have been thinking of setting up a remote receiver in a quite location linked back to a more conveniently located transmitter location. This would be an interesting extension. There a

It would be very important to ensure that there was no coupling between the two antennas. None the less a relative measurement between the two types of antenna, even at different sites would be very
To All from PA0SE Walter Blanchard quoted the RACAL expert who has in the past designed the Decca antennas as follows: circular This is not confirmed by computer simulation. Shouldn't you say "Compu
I know that it is off topic, and I apologies, but there is a good chance that the expertise will be on this list, and its always best to ask friends first. I am trying to measure the absolute value o
I agree. Stewart, g3ysx In my opinion, the Low Frequency Experimenter's handbook is very well done and excellent value. Thanks Peter for a job well done. John, G4CNN _________________________________
I know that this is a rather old thread that I have just come across when cleaning up my mail whilst waiting to fly through an ice storm to Boston. Why do the manufacturers still bother with S units.
How about in the short term we agree to put an unambiguous marker in the subject line for the high tech postings (ie [TECH]) and then subscribers who do not want to see the postings can filter them s

Gentlemen: With the completion of the TransAtlantic QSO is it time to consider moving on? I would hope that on reflection you do not feel the need to. The slow signal methods are just as much a part
