New here desperately trying to find an answer. I have a Can Am Spyder motorcycle with an OEM CB and third party, Edsets, helmet headset.
With the OEM antenna and coax the SWR was over 3 across from 1 to 40. I figured this is probably because there is so little steel in the bike there is an insufficient ground plane. I also was having a severe squeal problem on transmit. I decided to switch to a Firestik No Ground Plane antenna and coax. I modified the OEM antenna mount to accept the thread of the Firestik.
That solved the squeal on transmit problem. It also improved the SWR but not like I expected it to. It is about 3 across all channels. I adjusted it so the SWR is about 2 and below from channels 1 to 20 but it goes up to well over 3 on 40. That's not a problem for me as I almost always only use channel 1 riding with the local Goldwing chapter.
But I get a squeal whenever the CB is receiving a transmission. I've been using a Midland handheld for testing. I can't get rid of the squeal in receive. Anyone have any ideas what may be causing the squeal on receive? I talked to a tech at Firestik but we stopped when I could not at that moment tell him for certain that I did have an NGP antenna. I wasn't home to verify that while I was talking to him. I've had email exchanges with Ed Davis of Edsets but he doesn't have any solutions to offer at this point. He wants to find a Can Am with CB to do some more research into the Can Am system.
Where do I go digging now?
