And OR Bandstop / Notch (trap)
Its a direct sampling radio, the mixer (if fitted) will be part of a SoC.
It is what it is I am afraid. I don’t think a good BPF will resolve all the mixing products which will den sense the HT. It’s somewhat embarrassing when people below cannot understand why you carn’t (and should) hear them.
That’s why I’ve just bought an FT-60E…
My UV5 BaoFeng has just been assigned to the loft.
