Hi Version 1.0 of the new Jason software for G0MRF's DDS is now available. I found some time to test and debug the program on real hardware. It appears to work very well now. The frequency range has
Hi An "pre-alpha" version of the program is now available for PIC16F84. (not yet tested on hardware ;-) There wasn't room for both Jason and DFCW in the PIC16F84 so DFCW had to go... If there is inte
Jim, I heard your CW ID simultaneously with the Jason signal!? (outside the "yellow lines" of course). Are you using a linear P.A. and add the CW as audio to the Jason soundcard output? ...M0BMU JASO
Hi Jim, Any reports would be welcome. Part of Jason screen is attached. Displayed time is UTC+1h. Even the CW ID was "armchair copy" (aural) with SSB filter. 73 Johan SM6LKM TIFF image
Hello Dave I assume on this frequency it was a test transmission. If he had been looking for a QSO he would have operated in the data section (137.4-137.6). See http://www.g3wkl.freeserve.co.uk/lf/13
Walter, Jim measured 50 uV/m so MM0ALM's radiated power must be 10 dB below 1 kW - 100 watts. I would say 20dB below 1kW - 10 watts. 10dB less illegal but still too much... 73 Johan SM6LKM
Hi agn, Reino just replied via LF PSK31 to my e-mail report! Does this count as a valid QSO Malcolm? (Probably not as he changed callsign from OH1TN to OH5UFO in the middle of the QSO ;-) -- .eoe e-y
Hi OH1TN is calling PSK31 CQ in vain right now on 135.950-ish. Cut 'n' paste from DigiPan: -- CQ CQ CQ de OH1TN OH1TN OH1TN CQ CQ CQ de OH1TN OH1TN OH1TN CQ CQ CQ de OH1TN OH1TN OH1TN RPRT to e:mail
I have just worked Wolf DF0WD with 100% copy using Jason both ways. Congratulations Dave and Wolf! As Mal wrote, this is probably a "first". Perhaps also a "last" as Alberto is working on the more ba
Andy, This is too prescriptive. Yes, of course. It was just a thought, not a proposal. I was just dreaming. A clear case of the proverb "It's better to keep your mouth shut and let people think that
Andy, I think it's time for you to replace the batteries in your calculator. That's neat! But I make it 0.0083333 Hz resolution, I make it 0.00083333 Hz = 10.0000 mHz / 12. Both are submultiples of 1
Thanks Andy! A few questions: Q Followed by eight hex digits for the frequency command word MSByte or LSByte first? P Followed by two hex digits for phase word and [cr] You mentioned 5 bits (why not
Please, for serial protocol just use what Andy has already done or do the exact same functions, Integer steps at the limits of the DDS chip. OK. It looks like we already have a standard. Andy, can y
Hello I know there are some DDS users/programmers out there! We have probably not seen the final variant of "sequential single tone modulation" yet. So, in order to avoid unnecessary (and painful) PI
Dear Alberto, Also the problems of occasional double letters, and systematic errors are under scrutiny. I have noticed that when the transmission stops and Jason is exposed to noise, he (it?) usually
Wow! I read Dave's message at 2000 UTC, downloaded Jason 0.91 from his mirror site (qsl.net was dead...), checked my GPS frequency standard - it was tracking 8 "vehicles" - phase error was negligible
I vote for the narrow 17 slot format! To help those who can't switch sideband on their receivers, I would suggest the addition of an USB/LSB button to Jason. I guess it shouldn't be too difficult to
The DDS is totally down to Johan's wisdom while my contribution was limited to a low pass filter and the PCB design. What!? As far as I remember you did most of the hardware design and, what's more i
Yes, a Windoze vector scope would be a great tool/toy! Some sort of calibration routine would be needed for use, either feeding in a tone of exact known frequency and adjusting the NCO for a stationa
