The QRSS modes easily meet 2 and 3; in order to meet 1, a dot length of about 7 seconds maximum would be required. With the best possible conditions, I guess several stations might manage transatlan
I am not aware of any amateur radio WOLF reception so far that would not have been viable using QRSS, but the technique is at an early stage. Mike, I will share one experience I have had with WOLF. F
I think this may be the source: 73.6 CFH Naval-Halifax (Mill Cove), NS, Canada (FSK 75 Bd) Above found at: http://www.provcomm.net/pages/joe/introvlf.htm#Target Frequencies below 100Khz Dexter Dexter
Maybe a LDE (long delayed echo) signal? See: http://www3.sympatico.ca/hrc/haida/radio/csr5cm11.htm The RTTY signal I recorded a few days ago is now extremely strong in North Carolina at 2300 UTC. As
I figured Stewart may want to analyze the wav file so I uploaded it to: www.qsl.net/w4dex/73.6kHzRTTY28nov01.wav It's close 1 MB in size. Dexter The RTTY signal I recorded a few days ago is now extre
The RTTY signal I recorded a few days ago is now extremely strong in North Carolina at 2300 UTC. As Stewart told me the shift is 75 Hz. I have both Spectran and wav file saved if anyone is interested
LF conditions must have been excellent the night I heard the Rugby signal so well. I haven't had good audiable copy since. Tonight there is a lot of QRN and I don't hear Rugby at all but Spectran pic
Nothing seen on 72 kHz last night. It was a bit stormy in this area, and the noise levels were up. However, no fragments of your signals could be seen, indicating that propagation may have indeed sl
I lost all signal from the 73.3 kHz RTTY station by 0100 UT last evening. QRN was very high so the signal could have been just below my noise level. Relative signal strength logged are as follows: 21
Just for grins, I recorded a 15 sec .wav file of the 73.3 kHz RTTY signal and uploaded it at: www.qsl.net/w4dex/73khzRTTY.wav File size is about 244 kb. Dexter Peter, At 2100 hrs I am receiving a goo
Peter, At 2100 hrs I am receiving a good RTTY signal on 73.3 kHz. Since this is the first time I have listened for this transmission I have no reference to judge it's current signal strength. It sou
Things eventually did improve last night. This was recorded from 0430 - 0545 UTC: The wx forecast is fine for here, but will again by stormy in the south central U.S. John Andrews, W1TAG I just viewe
I am logging 72.399 to 72.402 tonight. Noise is higher than last night. Probably from the same thunder storm activity John mentioned. So far no signal detected. Dexter, W4DEX At 0100, still no sign o
John, Thanks for the explanation. You have always been able to explain deep technical topics in a way I can understand. Now can any Hoover be utilized for this application or do I need to purchase on
I'll be amazed if someone else doesn't copy this tonight! I just reviewed my overnight screen captures of Laurie's frequency. Absolutely nothing received here in North Carolina. John, are you using o
Can the -3db bandwidth measurement of the complete antenna system be used to determine the Q of the coil? Dexter If you use a larger capacitance resonance will naturally be at a lower frequency so yo
Congratulations John and Laurie. I have been watching Laurie's 72 KHz signal also. Last night I saw nothing. On previous nights several times I saw a 120 second line on 72.4014 (dash frequency) but I
John's idea sounds like a great tool for the transmitting stations to see how their signal are being received at near real time. I will be attempting to do the same. Look for updates at about 30 min.
I saw one good "AQC" and the measles, otherwise signals were much weaker than the night before. AQC posted at: http://www.gostanly.com/w4dex/135922_30Dec01.jpg Dex It seems to be a waste of time and
