[RFI] Weather Station on 433.92?

[Cortland Richmond]

Hi again, Dale,

Nice to see you in Cedar Rapids.

No, these really are low power, so should not be a problem for weak signal
work.  I understand there is  at least one ATV repeater whose audio has
problems from these devices, though. 

And of course THEY might have trouble with the new National QRO Simplex
Frequency, 433.925.   (VERY big grin!)
