Hartmut, Last night I found no improvements using the "Jimi Hendrix mode" in Jason 0.97. Dex will disagree with me, but I must confess that Jimi Hendrix was never my favorite at dawn. Later in the da
Gary, I have been seeing CFH from about 1900z when I started monitoring with Spec Lab. When did it start transmitting again? I'd say within the last two hours. John Andrews
Jim, An unusual form of words - rather similar to an e-mail I received recently from my new Nigerian business partners:< Wait a minute! I thought they were MY Nigerian business partners! Then again..
MessageWolf, By accident, I received Gary's mail when checking my inbox for any reports on an MSK test transmission this afternoon. Congrats and many thanks go to Ko, who -afaik- made the first succe
MessageWolf, Alberto, W1VD reported copy on my Jason Fast Turbo (the marketing dept. loves it) at 1952 UTC. We'll let Jay and Ko fight it out for the title. <g> Anyway, it works. Solid copy at 114 km
Lloyd, Understand about the interference. With CFH cranked up, I'm trying to stay above 137.5. If I do this again, I'll pick another freq. JA John I have a very strong Digital type signal at 136.95 a
Mike, How many WPM would this compare to in straight CW? Based on the standard word, "PARIS " (including a word space at the end), I make the International Morse version to be 6.5 wpm. There are smar
WD2XES will be running in the new Jason Slow Turbo mode tonight on 137.779 kHz. This will produce "dashes" of 48 seconds, which should look OK on a 30-second screen. You will need the latest version
Have been watching VO1NA, WD2XES and WD2XGJ on the CT1DRP and G3YXM grabbers tonight. Dave will wish that he had set Argo for slow, rather than regular speed. Conditions have been pretty good in the
Teo, It is very difficult for some of us in North America to see DX signals near that frequency, as our stations are transmitting there. It would be much better for you to transmit with the other EU
Jay, Walter, QRSS30 would be okay - QRSS60 would be better. By shutting down at 0600Z you are limiting the TA window. I'd suggest 0700 or even 0800Z if possible. Do you have an accurate frequency rea
MessageWolf, et al: At this point, I am getting 50 dB of carrier and opposite sideband rejection with the 74HC4066 mixer. I need to pick up a few parts, and will be back at it tonight. John A.
Jan-Martin, very interesting, and it is still allowed to use an additional notch filter, or did I misundertand?< At this point, no extra filtering should be required. The quadrature outputs from the
Wolf, I should have my version running on the bench tonight. It uses all four switches in a 4066, each one conducting for 1/4 cycle. The clock is just a Johnson walking-ring counter driving a quad AN
I've been tinkering with a phasing exciter that uses easy-to-get parts and produces a very clean signal from the sound card quadrature outputs in Jason and SpecLab. A preliminary schematic (hand-draw
Wolf, Was the L.O. using 74AC74 + 74AC08 better than the simple 74 HC 107 method ? No! I had done the 74/08 section before you produced the schematic for the HC107. It is simpler. Is that dual-JK ver
