Subject: Re: [BITX20] uBITX - A reboot of the old BITX ? something is dodgy there. the T30-6 that i use invariably needs more turns to get the exact inductance that predicted by the data. i don't know ever is going on. ?

So is there some inductance amplifying affect from the other two parallel windings?? Can anyone else with a spare 8:8:8 transformer lying around do a reading? ? ? ?
