Hello Chris, Can't ping it, can't even ping its numeric IP address, sounds like it's properly goosed....Domain name expires in April, hope Bruce remembers to renew it :) -- Best regards, Chris mailto
Hello Andy, OK, understood, I did some calculations then checked them against an on-line calculator and get figures of 68K and 12K for the divider. If I retained the existing 15K to ground I might be
Hello Markus / Andy / all, Please see http://www.gatesgarth.com/amp-simplified3.jpg I added 2 off 86k resistors as resistive dividers as shown. Voltages were as expected 1.87 and 1.86V on pins 2 and
Using a second variable current limited bench supply it switches state at 4.7V That's with just the original 15k resistors to ground on the input pins of the MCP1404 Best Regards, Chris Wilson On 3
Hello Mike, No thank *YOU* for the good ears and the reports, a good night it seems, all the very best for 2018 to you and yours! -- Best regards, Chris mailto:[email protected]
Hello Nick and Paul N1BUG Should this amp be driven by sine waves?? I assumed you were driving it direct from CLK0 of the Si synthesizer in a U3S, with square waves? -- Best regards, Chris mailto:dea
Hello Alex, Thanks for your interesting and welcome resume of the reports, much appreciated my friend, all the best, and thanks for the corrections :) -- Best regards, Chris mailto:[email protected]
Hi Stefan, Mr. Coil King much appreciated, the dead FET's box has not had much use recently, touch wood! -- Best regards, Chris mailto:[email protected]
Hello LF and VLF folk! I have built a couple of Softrock Lite II IF frequency receivers, normally they would be used to view another receiver's IF on a bandscope, but popularly they are also used on
OK thanks will take another look at this. Best Regards Chris Wilson On 26 Jan 2018 3:10 pm, "David Bowman" <[email protected]> wrote: Hi Chris. It may be worth going back to the oscillator and mak
Thanks for the replies! Should the `scope show the issue? I have access to a very good SA but am always loathe to use it in case I blow the front end, as at this low a frequency it needs the "absolut
I just completed two scope measurements at R17 to pin 3 of the divider IC. One of the faulty LF Softrock, and one on my MF one that works fine. the resultant wave forms are quite different. But I am
Hello Tobias and everyone else. Thanks for the detailed info, much appreciated. I managed to change the divider again, but this is probably the last time as a pad is lifting. I also put back a 22k re
Hello all. Today when powered up there was rarely any output from the divider at all, so I started again. I decided to try two things, build a little test rig with a spare xtal of the same 461.5kHz a
Hello Andy, I am having to admit defeat and defer to your diagnosis, I have managed to lift two pads removing the SOIC divider IC again, so await some bare boards from the US. I will modify one to ta
Hello Domenico, My congratulations to Markus and his compatriots, too, well done indeed. We have some very talented and altruistic people amongst us hear, it's humbling to hear of the marvellous achi
Hello Andy, I cannot test into the divider as I lost a pad off the PCB and have no more IC's left, but some are coming and I can jury rig the board for testing even if it won't be pretty, but I added

Hello Claudio, Thanks Claudio, but how do I fix this issue? I can rebuild an F1 engine, but this is outside my comfort zone :) -- Best regards, Chris mailto:[email protected]
