Hello N1BUG, Sadly VK3RF has stopped making these, I have had one in my TS-590S for years and it works great. Disconnect the Trimble Thunderbolt reference and it reverts to its own TCXO. There may be
Hello N1BUG, BTW, here is the WSPR15 enabled version I am using in case anyone has trouble finding a copy these days: http://www.chriswilson.tv/WSPRX_08r3058.exe -- Best regards, Chris mailto:dead.fe
Hello N1BUG, I have zero issues running the old WSPR15 implementation on Windows 7 64 Bit. I have run it for days and days at a time. I just checked it's under XP SP3 compatibility mode but I seem to
Hello N1BUG, When I have blown a FET on Jay's amp design and replaced it / them I have sometimes seen less than optimal gate and drain waveforms from the replaced FET's. A simple meter "diode test" o
Hello N1BUG, Probably teaching granny to suck eggs but if you take off the HV to the drains and just run the 12V supply and the exciter and `scope the gates you will quickly find the dead FET / FET's
Hello LF'ers Next project is a dedicated RX antenna and I am envious of G0LUJ's large aperture loop from Wellbrook but feel home brewing one might save me a load of dosh. Does anyone have a schematic
Hello N1BUG, I don't change any that remain functional and haven't had an issue. I do use a very cheap Ebay IR temp gun to check all run similar temperatures and find that a good way to see if one is
Hello DK7FC, Is the H bridge amp a published design Stefan, and if not, would you consider posting it please? :) -- Best regards, Chris mailto:[email protected]
Hello DK7FC, Thanks for the schematics Stefan! Do you know exactly what toroid you used (assuming it is a toroid) for the gate driver transformer please? Would the output level of the Si chip in a QR
Hello N1BUG, Paul, I have always shorted out any unused turns on the loading coil with no issues. The matching transformer has floating unused turns though, but I think it's similar to yours, again n
Hello Mal, It was me,2E0ILY. Thanks for the info. The Wellbrook loop is a large aperture wire loop, but as G0LUJ is a coastal location I think maybe that flatters the signals. I guess I should try a
Hello Stefan, Any chance of a few photos of the H Bridge amp construction please? I take it the BF862's in the optocoupler feeds act as current limiters? Any reason you didn't just use resistors inst
Hello Paul This is probably the best capture from last night, if you want them all I can zip them up and e-mail them, just ask! http://www.chriswilson.tv/paul.jpg -- Best regards, Chris mailto:dead.f
Hello LF'ers If I can get my TS-590 and squarer to work safely i will have a go at JT9-1 tonight, but I need to know dial frequency and audio TX frequency that is admissable on LF, can someone advise
Hello DK7FC, JT-9 on hold as I can't find the plug for the TX signal out of the TS-590, I had forgotten that I needed to make a lead to the antenna change over box. I tried a couple of TX only sessio
Hello LF'ers I think I am now good to go with JT-9/1 this evening but I am pretty much bound to 137.550 KHz if that is acceptable? Would welcome some local contacts to see if all is well before getti
Hello Rob, Myself and I think Paul, N1BUG, both have these HP generators, would you be willing to give a brief write up about how you are using yours for Ebnaut please and what peripherals you are us
Hello Wa3tts, Not sure why it is doing this, the locator is set to IO82 without the qv and the Prefer Type 1 Messages box is ticked and the app has been re-booted several times. Very odd! -- Best reg
Hello Ebnauters Would a KiwiSDR (which I do not own but was thinking of buying) have adequate LF frequency stability for Ebnaut reception given it uses 1PPS from a GPS receiver to stabilize the frequ
Hello Markus, Thanks to you and all who have replied so far. I have a thought. My TS-590S has this GPS locked LO fitted, would this allow me to use the 590 for Ebnaut RX ? The kit is now no longer av
