Hi Ken   Off your topic but had to relate that while on holiday last week on the cliff tops at Corton nr Lowestoft (abt 95miles) I copied you working Chris G3XIZ. I was using a 80m dipole up 6m and an unmodified Kenwood TS50s you were a very readable signal a couple of S points down on Chris but Solid copy!! FB signal there Ken. Prior to your QSO I worked Chris QSX (sort of) me on 3.566. I called a few times but I guess you were not set up for QSX?   Anyway nice copy there on 500 Ken.   73 petefmt --- On Tue, 14/7/09, Ken <[email protected]> wrote: From: Ken <[email protected]> Subject: LF: Re: RE: Microwave oven transformers To: [email protected] Date: Tuesday, 14 July, 2009, 8:33 PM Jim. There will probably be a fair bit of technical smoke comimg out of Luton, but that is what our hobby is all about, any other usefull sugestions?   Krgards.

Does any one have experience in using microwave oven transformers in high voltage power units, I acquired two of these at the weekend. I was informed that as they stand the voltage regulation is poor, to improve this the 'Core Shunts' should be removed, (these are laminations between the two stacks), removal of these 'shunts' also has the effect of considerably increasing the magnetisation current. The solution to this seems to be to use two transformers, connecting the both primaries and secondary's in series to restore the 2KV output voltage.   Any comments on this most welcome   Note for Mal, this is serious stuff not for appliance operators.   Regards Ken Wright   73 de M0KHW
