Mathew,

 

We have had problem back in Oregon with the Wi-Fi guys running the 2.4 GHz
outdoor wireless amps that mount at the antenna. They seem to be sending
spurs all over the band. With the PassPort VHF system on the same tower the
receiver would 20db down and then turn off the Wi-Fi stuff and then it goes
to normal operating as it should. What type of 2.4 GHz, are you running an
amp, what type of antenna. Also you may want to take the antenna apart and
see if it is filled up with moisture.

Subject: [Repeater-Builder] 2.4 Ghz wireless radio and 145.410 repeater

 

I just had a 2.4 Ghz internet wireless antenna mounted at the top of my 
120' tower which is where the antenna is for the 145.410 repeater. I 
am getting intermod into the system that causes it to hang open. 

Anyone ever had these issues and how did you go about remeding the 
problem. And I can't shut off the internet as the family would hang 
me, and would rather not shut off the repeater.

There is besides the TXRX duplexers two DB4001 filter duplexers on the 
system. Funny part is that once it starts the interference, I can 
remove antenna from the receiver and it continues to intermod until I 
kill the transmitter. I can hit the remote PTT and it will key the 
repeater, no noise into the system until I reattach the antenna port to 
the receiver.

Thanks.

Mathew
