Turn off the mains supply in your house and power your radio from a battery (if you have one) and see if the noise persists or not

Thanks for your reply Buick, unfortunately I do not have a battery that I can try, do you think it maybe an issue with the power supply?

I Doubt its a power supply issue, Sounds to me like interference being picked up by your antenna, Unfortunately interference also called QRM is a big problem for a lot of radio users these days, Numerous things can cause it, TV's, Heating Systems, Chargers, Lighting etc etc

Hi, I have the THUNDERPOLE SILVER ROD1/2 WAVE antenna bolted to a sky dish pole and I am using a CRT SS6900 radio, I can hear some traffic on it but any time I go to speak, it doesn't seem like anyone can hear me. Can anyone advise how I can check if I have everything set up correctly? I have attached a picture of my antenna.

Looks bad assembled to me. What's SWR on channel 1 and 40?

The bracket looks a bit close to the radiating element possibly causing SWR issues

On FM, CH1 and CH40 both coming through with a SWR reading of 1.0 on the radio?

It is just bolted onto the pole, do you think I need to get a larger size pole?

Stand off brackets and a pole. Get the bottom of the antenna at least above the guttering. I wouldent like to watch that in high winds at the moment.

Do you know it would be possible to just buy a longer pole to fit into my existing bracket?

Before blaming the aerial are you sure your radio is working?

Yeah I can hear people on it and I have been able to talk to some locals on it so far?

Anyone able of offer any advice please?

If your sure the radio is working and the SWR is good then try and get the antenna up a bit higher

Does touch antenna touch he gutter?
IMO length of marked element is wrong.
SWR 1 seem to be too good to be true.

No it doesnt touch the guttering at all, I believe that it is at the markings which on the antenna, do you think it should be longer?
