Hi Graham, Thanks for the pointer to the document. So I understand that you can get the Opera (Windows) program to just export the bittimes. Well that makes it extremely easy to send Opera.. The PIC
Hi Eddie, Well that would indeed make it extremely easy to send Opera.. I will try that anyhow (and first). Oh... and when you find a method to make projects (more) flash, bang and vapour resistant..
..and I just received a PM from Marco DD7P that he decodes my WSPR-15 just fine! So an FSK freq deviation of nearly 5% is handled just fine. Minto pa3bca -- Ceterum censeo Carthaginem delendam esse F
Hi Mal, Thanks for the report and the screenshot. I just finished building a new (compact) 472 TX using a cheap chinese AD9850DDS ($ 3,50). Output 100 Watts. Using a PIC18F2520 to control the DDS, no
Hmm I just found an email (to this group) from Andy G4JNT, dated 17 jan 2013. w.r.t the AD9850 and WSPR-15 he writes the following: Incidently, the low cost AD9850 DDS modules with their 125MHz clock
That must be 475800 of course.. -- Ceterum censeo Carthaginem delendam esse --Original Message-- From: Minto Witteveen Sent: Wednesday, February 06, 2013 21:58 To: [email protected] Subjec
I am currently TX-ing WSPR-15 @ 472800.. Just finished WSPR-15 programming in my PIC controlled AD9850 + 100W TX 'Normal' WSPR works fine (got lots of spots today) but with a tone separation of only
Hi Graham. Thanks. Yes I see.. I just installed the latest version of the Opera software, and found the Op4 and Op8 frequencies. And generated the 239 bits for PA3BCA. Now tomorrow (its late here) I
I too have built a standalone 472 100 Watt TX with a PIC (and an AD9850). The software I have written so far now handles CW, QRSS, DFCW and WSPR-2 and WSPR-15 (thanks to Andy who wrote up a nice desc
Hi Marcus, Thats good to hear. So it seems that WSPR is more forgiving than the documentation suggest and I expected (giving the tone separation with a 4 digit accuracy...) Regards, Minto pa3bca -- C
Oke... just implemented Opera in my PIC code Op4 running now.. 73s Minto pa3bca -- Ceterum censeo Carthaginem delendam esse From: [email protected] Graham Sent: Sunday, February 10, 2013 01:58
Hi Eddy, Where did you get the description of the OPERA protocol? And did you write the encoding yourself? I found a protocol description of Opera on Andys (G4JNT) website, but it is reverse-engineer
Hi stefan, I tried to call you in rtty between your beacon transmissions, but either my signal was too weak or you were not listening at that moment. Oh well, better luck next time? 73's Minto pa3bca
Hi Stefan, I can decode you through Twente WebSDR, abt 50% copy right now. Im sure this will get to a solid copy later tonight. My own sig is not much better, and I am _much_ closer to Twente... 73s
Ouch! No RTTY qso with you then on 478 :-) My antenna is real c**p On the other hand... I did have several CW QSOs with EI0CF and SM6BGP so at least something is possible. THEY however have impressiv
Hi Eddie, Yes, after I sent the message I (re)checked and found that I switched mark and space frequencies (due to some obscure reference I used. serves me well for not checking). So the consensus is
That settles it. The info I got (from an untrusworthy source it seems) told me mark is 2125 and space is 2295. See my original message below. But it is the other way around. But it is only independen
Yes Amtor might also be interesting to look into. And Ill stick with FSK modes only for the time being, lineair modes are not an option with my PIC+DDS9850 TX for now... -- Ceterum censeo Carthaginem
Graham, Well it has been an interesting experiment, including writing the RTTY software for the PIC. But I do not think that RTTY will ever be one of the most used modes on 472. Although DSP software
The RTTY test(s) gave me inspiration. So I programmed some (quick and dirty < 1hr programming) RTTY subroutines for my PIC2520+AD9850 472TX, just to see if I could get some results. Then downloaded f
