Default RE: single vs. dual conversion receivers

dual conversion has nothing to do with noise rejection. it is not a consideration in range calculation. single conversion has a vulnerablity to another transmitter at just the right frequency such that a 455 harmonic is generated and is passed thru your receiver. not good . dual conversion recievers with 2 xtals were invented to obviate this vulnerability. jr has a way of taking care of this with single conversion. i believe that when you buy a single conversion receiver you have opened yourself up to that vulnerability. park flyers seem to get away with it but i dont know why.
