Hello Rik / LF Those results tie in well with my tests on 500kHz. Having run WSPR spaced with QRS3 for some years I was surprised how easy it was to read QRS3 FANT0M tagged to OP4 compared with the O
Mal Fact. Everyone including G3KEV has missed my QRS3 and QRS10 on 500kHz every time I have had it on, using this same TX, in fact I removed the PIC which sends the QRS and inserted OPERA, viola PA0'
Dear Jim, Rik, Laurence Thanks for the information, it does seem from all tests that QRS3 and OP4 are about equivalent. QRS as we know takes a human to notice its there among noise and can get missed
Hello Rik Thanks again for your thoughts. I don't usually disagree much with what you say.:-) Your extreme example of 20WPM for 4mins is totally unfair to Morse, due to exactly the same reason, you c
This one worked before also on the G3ZJO G0KTN path:- After dark QSB starts on 500kHz even OP4 can become a struggle, the PA0AM path again. 18:52 18105 PA0AM Op1 -22 dB 322 km Actually on 500kHz 18:5
Yes OP8 decodes but almost always either equal S/N or worse. E I would go for OP2 on 500 , that was the speed that produced the best results at the start , did you have any OP8 decodes? G. This one w
My previous tests over the G3ZJO / G0KTN path have been consistent. Trevor suggested trying to use the PA0 stations. I found a better position for my 750mm square indoor loop and PA0OM was steady cop
Great stuff, it looks like characteristics noted by those confounded little QRP operators (me) on relatively short paths also applies to QRO and T/A paths. When I went off to bed Op2 seemed to be doi

Oh BTW, the WSPR is every 10 mins, in between there is some funny up and down stuff for the QRS aficionado's, go on, you know you can read it. E On 02/02/2012 21:53, qrss wrote: Just checked the Pwr
But but but but, how do you know some QRS is a Beacon until you notice it and decode it. You Mal then normally post a comment about the 'time an band width waster'. I am pretty sure that until yester
We all seem to have agreed to compare OPERA with a QRS speed which takes the same time to send a call sign, correct or not? A QRS beacon can send the call continuously all day and successive periods
Hello Andy We do need to refer back to my original posts here. Yes OP8 decodes but almost always either equal S/N or worse. After that Graham asked for what I meant by worse. I have been keen to run
Sorry LH A plethora of messages to myself. I have tried other means. Mal You are TX'ing OP8 on 500kHz, that is fine, Graham suggested a test I am decoding you fine but you start to TX around every 6m
Thankfully such 'facilities' can be ignored and the original concept, a slow easily on / of keyed beacon mode for LF exploited.. Eddie G3ZJO On 02/02/2012 12:18, Terry GW0EZY wrote: Mal I’m sur
Mal Would you like to try OP16 on 500kHz, with our distance apart it should be a very viable test. I can push a button and send OP16 instead of 18 at any time. 73 Eddie On 02/02/2012 09:47, mal hamil
Hi Jim Was -31dB the limit of decoding for OPERA, ie could you take QRS3 to below copy ability yet get decodes from OPERA even if not 100% of the time. I am still searching for the reason for never a
Hi Graham I am far from anti, would just like to see some proof with my own eyes, with an hour between mode changes propagation can of course be totally different. From my example below within 1 minu
Hi Stefan It was very strong (usual strength) with me too I suspected the usual culprit, my Grabber Wide View has been on and off a few times today so the evidence has gone. Eddie Visible on many VLF
