I have a President Grant 2 (latest model) attached to a Sirio 2016 antenna with low loss coax. Signal strength and set good but radio picking up a lot of static. Can anyone recommend a noise filter or other method of reducing the static. Thanks

Hi Baz
What S level is the static/ noise level showing on the meter ? Are you getting the same level across the whole band range of the rig ? Does the NB button make any difference ? A really good thing to try is run the rig from a battery and then turn off the electric @ the fuse board , check the noise levels again , if some improvement then you know it’s something within your own home

Unfortunately that is about par for home base using a vertical in a town location ,some members have more than that , trying the antenna in a different location may help , going horizontal will most definitely help but your local contacts will be down signal wise , there is always a compromise is this hobby

It certainly has Barrie , 30 /40 years ago it was us causing the problems and finding difficult to find a free channel , funny how things go full circle , fingers crossed things improve @ your QTH or another member can come up with a solution

Then try these. https://www.ebay.co.uk/sch/i.html?_osacat=0&_odkw=Torroid+core&_from=R40&_trksid=m570.l1313&_nkw=Torroid+ferrite+core&_sacat=0
Wrap around all your cables / wires to and from your radio.

Have you tried using an external speaker with built-in filters? I use an Icom SP-34 (link below) which has two high-pass and two low-pass filters and it helps to get rid of a lot of noise / static.

Never even considered the street lights but thinking about it there is less noise during the day. I was thinking of an external speaker with a noise filter but if it is the street lights maybe that would just be a waste of money.

LED street lights in my street are a terrible source of QRM.

Grants are known for this issue , worth a shot with a few chokes . There some big chunky ones you wrap coax around it . Would place one under antenna and another next to the rig . If / when you run of a power supply do this also after the plug , even remove outer to the flex and get more turns and place in a plastic box etc to protect it .
I only buy ferites from trusted companies to know exactly what your getting not off ebay or Amazon etc, also you have to use the right mix .
