Default Re: Two or three IF stage Chinese radio kits.

Having just looked at the sellers of the six transistor, one IF kits & one is definitely saying that: "R4 can change gain of the medium frequency amplifier.(V3)".
They also give V1 & V2 as 9018F & V3 as 9018G. I take it that the suffix denotes a particular band of hfe value.
