Hi Les, thanks for copying this message to me directly, as I have yet to see it via the IRCA list. I am familiar with LF QRSS experiments with *extremely* slow morse, to where a single dot is a minute or more. This isn't where I am going really. I'm pushing towards a happy medium to where the CW characters are simply long enough for Spectrum Lab, running at a normal waterfall speed, can easily display the morse characters. If you take a look at the Spectrum Lab dump I posted in a previous message, you can see that Spectrum Lab is already displaying the breaks between the CW words, i.e. DE and KTMI etc, at the normal slow speed CW the stations normally use. Lets take it down a few notches, if the morse was running at a speed of where the dots were 1 second, the dashes 4 seconds, spaces between letters 2 seconds and spaces between "words" 3 seconds, then Spectrum Lab could easily display the morse characters right there on the waterfall. I'm thinking easy mode and not hard core QRSS which is pretty specialized and does take TXCO's, etc. I'm looking to where a DXer with just an average receiver that has SSB capabilities, a PC with a sound card and running the freeware Spectrum Lab can easily monitor a test and "see" the CW ID's, even so weak the ear can't detect them, right there in Spectrum Lab. That's why in the Spectrum Lab dump I posted, I used USB with a 3 kHz bandwidth filter. Now that I think about it, I bet it is possible for a AM only receiver to display the 1 kHz CW tones in Spectrum Lab. This sounds so do-able, and able to take these DX Tests to a whole new level. Coast to coast loggings, and giving foreign DXers a real shot at conclusively IDing these tests. All without fancy equipment. :) 73, Brandon Jordan Memphis, TN www.bcdx.org _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
