Hello Paul, As Mrs. Beeton was alleged to have written in her 1920's cookery book about preparing Jugged Hare , "First catch your hare..." Then we can argue the legitimacy or not of the endeavour ;)
Hello LF'ers, I am taking more of an interest in Ebnauat, and was wondering about hardware versus software locking of the PC clock to the sound card clock. Firstly, are there motherboards and sound c
Hello LF'ers Is asking for a .usr file for receiving DFCW60 with SL too simplistic a request if I modify it to suit my sound card ? If not would anyone share one to play with please? Thanks. -- Best
Hello DK7FC, That's very good of you, it might have to be next week as work is manic and I am all over the place, but this seems very appealing! Thanks Stefan. -- Best regards, Chris mailto:dead.fets
Hello Wolf, Thank you and thanks to others who have replied. Next week I should have a bit of free time to spare, so I will try and get to grips with this remarkable software! Once (if...) I have gra
Hello Marco, LF has been dead all day, maybe it is a reporter problem, but you would still decode locally, surely? Are you seeing MF receptions on your WSPR app window? -- Best regards, Chris mailto:

Hello Paul, If my similar amp exhibits ringing on the drains (which I monitor in real time), it means an antenna mismatch or a dicky connection (PL type plugs were the cause, cheap junk off Ebay, a c
Hello N1BUG, Hello Paul, by way of comparison my home made PCB is attached right by the FET's by copper wire 90 degree angles, soldered to ground plane of PCB and ground plane of the main amp double
Hello Paul, typo in my last reply, the Teflon co-ax to the LPF is about twelve inches long!! Sorry. As Jay says, it's not the ringing per se, but if the ringing peak goes over the fairly low headroom
Hello again Paul What's the vertical board in the end of the case? If it's the multiplier I am not qualified to say what having in the same box as all that RF might be, but i would have some concerns

Hello Paul, the audiofool speaker wire I used is very pliable even at room temp. I tried it as it's a twin (bonded) flex, so no need for an outer sleeve to bond the two tight together. I found a shri
Hello Paul, here's a link to my prototype build, the more I think back to bad drain waveforms the more convinced I am that the major fix was added decoupling. I read Jay's very salient post about non
Hello LF'ers Software to close a relay at a given time, perhaps via the serial port? I am looking for some simple software to enable, at a given time to within a second or so, derived from the PC tim
Hello Andy, Thanks for that, just tried it via Remote Desktop and it appears to open port 6 as requested fine. But at the designated OFF time the whole programme appears to close, is that as expected
Hello Paul, effectively the same as I am using, so I think you can safely discount those. Have you tried de-coupling caps yet, especially on the driver IC? I think the hump on the gate waveform is th
