Yes, the band is still full of surprises, I thank the dog for waking me up and me looking at the pc Best Regards Chris Wilson On Mon, 18 Feb 2019, 19:14 Rob Renoud <[email protected] wrote: Paul
Hello Joe, I did not know your father was an amateur operator too. My condolences to you and your family, when did he last operate? It's great to see you carrying on in his fashion though, he must of
Hello Rik, I have a series of scope captures from my W1VD amp showing huge voltage spikes on the FET drains at the end of WSPR and especially OPERA TX sequences. I suspected inductance was the cause.
Hello Paul. everyone A series of overlapping scope captures at end of WSPR sequence with expensive high voltage / current Wolfspeed FET's that usually survived, into the antenna and into a 10kW dummy
Hello N1BUG, Just to add things were MUCH worst using a X2 multiplier circuit (Jay's). I now use an exciter frequency of X2 direct both from the U3S, and as of late X2 from the TS-590 into a simple s
Hello Eric, Yes, the output is a square wave when I use the U3S I take the output direct from CLK0 at 2X frequency (set in the U3S menu) via a co-ax to the input of the W1VD amp to Pin 3 of 74F74 wit
Hello Andy, Thanks for that! Bearing in mind i am not the sharpest knife in this drawer, would that perhaps explain why the U3S Si5351a output drives more reliably at 3.3V than say the output of a do
Hello Eric, No, I have always run the U3S in X2 mode as far as I can remember. No doubler, no squarer, just straight out of CLK0 to Pin 3 of the 74F74. And no issues at all. Thanks. BTW, I really adm
Hello mal, It was a joke :) G0MRF has had an awesome signal of late, so I jokingly mused he may have bought up all the amps, whereas he currently has a very good antenna, in actual fact. He hasn't co
Hello all, I have had to repair my window line feeder several times due to flexing in the wind breaking the copper coated solid steel conductors. Before making my own feeder I thought I would ask if
Hello, I was the boy to come to for nitrogen triiodide when I was at school, nearest I ever got to liking chemistry. There's probably still a few purple burn marks on various benches to this day... A
Hello Paul, I'll read that tonight, thanks for the link. If the neighbours knew I was reading this they'd be, errr.... worried ;) They think I am "suspect" with the aerials and electronics, already.
Hi all, I just sent this message to the WSJT-X forum, would anyone support this request? If so please respond there. If Slow JT-9 could add this I would find it a very useful addition :) ~~~~~~~~~~~~
Hello Jacek, Thanks for the links I will try a Google Translate request on the forum you mentioned, I appreciate your trouble and time, all the best! -- Best regards, Chris mailto:[email protected]
Hello LF'ers, Looking for ideas re automatically swapping two RX antennas over to one receiver timed to WSPR or other timed digital modes to compare performance, Anyone got any input please? Thanks.
Hello Rik, I wish I could assist but it's far beyond my remit. I would however like to thank you for spending the time and grey cells looking at this, it's much appreciated, thank you. -- Best regard
Hello Claudio and all who have replied here and by e-mail. I am liking the Spectrum Labs idea, but SL is a daunting application, but I am sure using it in his simple manner can't be *THAT* hard :) I'
