Does anyone know the colour code for TOKO 10.7 Mhz printed citcuit
transformers?
Which are the IF , oscillator and dicriminator colours?
Jim VE3DDY
They are in 10,7MHz:
orange 1º IF 10,7 (This is the can to be used in BITX)
(100pF capacitor in parallel)
green 2º IF 10,7(uncommun) (100pF capacitor in parallel)
pink (discriminator) (without capacitor as usuall)
blue (disciminator used in old radios)
(without capacitor as usuall)

In 455KHz:
yellow 1º IF 455KHz (1nF capacitor in parallel)
white 2º IF 455KHz (1nF capacitor in parallel)
black AM detector (with secondarie) (1nF capacitor in parallel)
black FM narrowband discriminator (without secondarie)
(1nF capacitor in parallel)

Some others Blue used in 27-34MHz (30pF capacitor in paralell)
All other used TOKO Cans with o without paralell capacitor.

Good Luck
