Are you still running identical ERP ? The Olivia trace looks a lot stronger on the waterfall and I can't see the MFSK signal at all, even when it is decoding well. Same MultiPSK display on both. Andy
I have (sort-of) sorted out the transmitter control problem. While both WSPR.EXE and WSJT6 both refuse to properly control the PC-installed COM1 port, they do both behave properly with an FTDI type U
If certain ISPs incorrectly classifiy like this, I wonder if they could be presented with a "Defamation of Character" claim... under Human Rights legislation or whatever. Andy G4JNT www.g4jnt.com
I'm packing in for now - need to go and cook some dinner. Bought a lot of spices and other ingredients for Indian cooking yesterday, some of which won't keep for long so must go and use them up. Hope
I registerd with WSPRnet and it is showing me as a user. Have just uploaded the first spot. It still gives my loc. as IO90 and not IO90IV What's it got wrong. Andy G4JNT www.g4jnt.com
And he got a good decode both those two times, with the frequency reported as 870 in each case (odd minutes listed in the database, coz of high Dsec setting). Surely not two oddities, exactly cancell
Oh dear, I have to agree with Mal for once. I'm fully with you there on grammar and punctuation in modern usage. I know of one teacher who refuses and returns any written work that makes use of Text-
I disagree - ERP is the licenced figure, and its what really matters in the propagation tests. WSPR only allows a few values, with several dB between them, and it really should be possible to get an
I haven't really been following this thread, and have deleted many of the relevent messages, unfortunately. But you can quite safely assume that all timing, apart from the ititial even minute kick-of
With this talk of grabbers, I'm surprised no one saw my experimental SMT Hell Tx earlier this evening (around 1830 - 2000) on G3YXM's grabber. Having resurrected the code for a direct DDS driver that
Provided the software uses 'proper' windows calls to the RS232 port and doesn't try to do anyhing clever (or ancient) it shoud work fine. Make sure your USB serial interface is a full external COM po
Yes, can't work out where the frequency shift came from. I did initially lock onto Jim's tramsission at the begining of each of his overs, so I would indeed have jumped in freq a couple of times. Sub
I'm WSPRing again. Tere was a request earlier this week for some more QRP operation, so I've put a switched attenuator into circuit ready. Currrently running at the original 80 Watts figure, but thro
It has decided to update my loc. now without having to do anything this end!. Wish it didn't use lower case second letters - that is not the standard as defined by the Maidenhead committee! Andy G4JN
Yes, just about the same level of decoding, but MFSK certainly looks weaker on teh spectrogrram. Need to stop Rx and tunr off now, but will monitor this reflector Interesting stuff - half-tempted to
Yes it is. All freqs derived from the master OSC input with dedicated PLLs. BFO can be tuned in 10Hz steps +/- 8000Hz. Some RA1792 radios have 1Hz RF tuning steps (not mine), but don't know if the BF
Some spectrum plots of the WSPR signal can be seen at http://www.g4jnt.com/wspr-spectra/ These were generated at 1500Hz using WSPR.EXE, directly converted to RF and fed via an attenuator to an SDR-IQ
John, G0API, has been monitoring my QRP WSPR beacon most of the afternoon, and getting the occasional decode at a S/N of -19dB, ie quite good. However, he only manages a decode about one time in 10,
Is there no privacy on this band ! - all I was doing was going through the various software packages, making sure they all give the same drive level.. And yes they do, interestingly. Must be designed
