Hello Hugh, It looks like you have managed to resolve the multiple signals from me at your end, nothing has changed here, I have seen no multiple WSPR receptions from you reported over the last coupl
17 November 2017 Has there been a previous trans Atlantic reception of a JT-9 signal from the UK? -- Best regards, Chris 2E0ILY mailto:[email protected]
Hello Stefan, Thanks, I was detected last night twice I think by N1BUG and I was using JT-9 (one minute TX sequences). For whatever reason Paul did not get the spots showing on the PSKReporter site,
Hello Paul, I too look on in awe at the VLF stuff Stefan and Paul Nicholson and the gang get up to, and similarly whilst I do not fully understand Ebnaut it is nearly unbelievable what they achieve,
Hello Roger, I am very far from being an expert but you seem to have done all that's required. I find OPERA a dream to set up and use, if only other amateur apps were so simple and find the ports the
Hello Marco, Many thanks Marco, yes there has been a period of reliability! :) thay are working well but not as well as these FET's in the US last night, which is most impressive :) 2017-11-21 04:40
Hello Jan, That's an excellent reporter site, pity it doesn't do JT-9 as well, my recent experience with PSKReporter is spots using that mode are flaky at best, maybe user error, i am not sure,, but
Hello Paul, I think I may have asked you this before (age and the stress of marriage etcetera, sorry...), but are you able to monitor OPERA as well? Re no spots for JT-9 Philip of PSKReporter fame ha
Hello Roger, Thanks for the four spots so far. I send WSPR2 then JT-9 every 12 minutes. Unable to receive at the moment, my Kenwood TS-590 suffered a serious mischief the other nigh :( -- Best regard
Hello Domenico, A very happy Christmas and a healthy and prosperous New Year to all LF folk, please let Santa and his reindeer descend safely without any RF burns :) -- Best regards, Chris mailto:dea
Hello Andy, Is there any point in Paul putting his dummy load on the end of his 75 odd meters of feeder co-ax outside? And then on the secondary of his matching transformer when tapped one to one? In
Hello N1(de)BUG, Thank you, I am flattered, but don't for one moment go thinking I actually know what I am talking about, for God's sake! I am just bouncing thoughts, after thinking what I would try,
Hello N1BUG, What does the scope show if you look at each side of the choke in the PA? I did some tests ages ago using the stacked chip caps on the PA side of the choke compared to conventional leade
Hello LF'ers, and a happy and healthy New Year to you all. I use my U3S QRP Labs exciter to drive a PA on 137kHz, and it works fine. Hans, the designer, made changes allowing a 180 degree out of phas
Hello Clemens, Thanks Clemens, I'd need two, correct? Could I try say 4 to 16 turns on two FT-37-43 cores, which I have? Will the Si synthesizer chip have enough "ooomph" to drive them? -- Best regar
Hello Andy, MCP1404 IC fitted, as soon as power to the PA FETS is applied (even 6V) one of the gate square waves either disappears or becomes extremely random. Swapping inputs to the driver IC makes
Hello Markus, I am now using an MCP1404 so I can delete the 5V regulator http://www.gatesgarth.com/MCP1404.pdf So am I ok using another pair of 15K to pins 2 and 4 up to pins 6 (12V DC +)? Thanks, th
