RFI from wireless 433Mhz systems ???
I was recently looking at a wireless weather station operating at
433Mhz. The question is, has anyone some real experience at having one of these and a 432.1 Mhz station. Not that I have the 432.1 antenna up, but I still need to know. 73's Ralph -- Personal email 's a SPAM trap) |

I got one just to see what they were transmitting and I find it hard to
hear. Mine only transmits every 30 to 60 seconds. K9DCI "Ralph Lindberg" wrote in message ... I was recently looking at a wireless weather station operating at 433Mhz.

hi
I have one of these weather stations the outdoor sensor is about 12 feet away from receiver and the receiver is about 6 feet from a hf / 2m and 70cms radio installation and all is fine , no problems . however if I put the receiver within 2-3 feet from the radios I can sometimes pick up the sound of the sensor in my speaker system , and I have been told that it is also transmitted on my outgoing audio , must be some sort of mic lead pickup not too sure , but in general its quite expectable . hope the info helps. (ps) mine was from aldi the £9.99p one last year deal. "Ralph Lindberg" wrote in message ... I was recently looking at a wireless weather station operating at 433Mhz.
