Thanks Gary Because of a very very slow and unpredictable BT so called broadband connection, all my mail is directed to Trash Can .... don't ask.... So unless I catch it before being dumped I miss it
Hi Chris, Sorry to hear that. Just checked to mails after beeing abscent the weekend and wanted to wish good luck too now but just read your mail below. I assume the breakdown immediately de-tuned yo
Hello Stefan / LF, All was going last night well until I heard sparking from the aerial distribution box each time the carrier was turned off. After about 45 minutes the PA FET's blew up. I did some
Pete, I read a mail that Chris wrote stating :- a:- What time did the transmission end? Because I have 10s of Mbytes of recording to backtrack through and I don't want to be looking at the time whe
Thanks for looking Roger and chaps but game's over for tonight. I've insulation breakdown somewhere in the aerial circuit and I can't fix it until daylight. Maybe try again next weekend. 73 Chris G3X
Does anyone know a:- What time did the transmission end? Because I have 10s of Mbytes of recording to backtrack through and I don't want to be looking at the time when there was no transmission. b:-

Hi John, It looks professional! What is the maximum spark length you can achieve? You are using a motor and a rotating contact to switch the primary to a capacitor bank? Would be interesting if i wou
Chris, No copy over here in Burwell: I think what I saw was just band noise. There are several things to improve here still (antenna, preamp, filters, Spectrum Lab settings). I even tried screwing th

Chris I dont think slowing the drive edges will be the answer. This is a switching PA and needs to switch quickly otherwise the dissipation will rise rapidly. Any slowing edge will have to be on the
Hi Chris, You are using a class D PA? Maybe you don't even need a output transformer if you apply a coupling winding on the coil. Why are the FETs blew up? Overvoltage or overtemperature? And what ty
