New Transmitting Equipment

[105fmteesside]

Hi,

I may have the option to purchase some new transmitting equipment for my radio station. A 60 watt pll and band 1 link set up. My question is, if I am running this from my house wouldn't this become noticeable at such high power, as it would knock out the neighbours TV signal so I have been told. I want to broadcast from my house and cover Billingham, Stockton, Middlesbrough (basically the whole Teesside area) but not on too much power that I will be interfering with other services.

Thank you.

Welcome. To avoid causing interference install a low pass filter (7 pole at least) between the transmitter and antenna.

HERE is a link to a 9 pole filter rated at 60 watts. I recommend a filter that has at least a 20 watt headroom over your transmitter's total power output.

Also its a good idea to have an SWR meter inline after the low pass filter to monitor the antenna system. Even slight issues with the antenna system can cause problems with interference and degraded coverage performance.

Peace!

If your transmitter gear is properly tuned and running into a decent filter then it should not interfere with any services outside of the frequency you are using in the first place.

Now given that, it's not unheard of having people complain because they have crappy built consumer electronics that will be overpowered by a near by radio station.
This happens even with legal broadcasters where some little old lady living a few miles away calls in and complains that the towns radio station is coming through her telephone handset even though the radio station is running within all legal specifications.

60 watts however is no 50,000 watts, and also I am assuming you're using FM which seems to cause even less headaches with RFI getting into neighbors stuff.

Worse case scenario is that you knock out a portion of your local neighbors FM radios because of overloading their front ends, not because you are truly causing interference in the traditional sense, that is if you follow the advice given above.
