433.92 MHz (was: Re: [VHFcontesting] Re: For you 432 experts...... ...)

[John (JK) Kalenowsky, K9JK]

LOTS of 'consumer' products use 433.92 MHz...while that is a 'fair' distance 
away (1.82 MHz) from the home of weak signal work in the 70 cm Band, I'm 
surprised we haven't seen MORE problems with 'interference' from (and TO) 
such products. Or maybe we have and just have not been as persistent as 
David H. in tracking his down.
