- Newer vehicles cause a lot of unwanted RFI (Radio Frequency Interference) on your ham radio receive. Snap on ferrite beads can eliminate a lot of it, along with routing of your power wire, location of your base unit and even grounding.
I have never heard this kind of noise from an AC blower fan in a mobile. 2024 Nissan Frontier. I have a few more snap on ferrite beads to get rid of the rest of this noise, I'll post when i have it handled.

The ferritte's do help alot. I put them all over the place on the base station. Mic cords, power cords coax cable's.
Are using a noise filter on the battery to the supply voltage. I ran a qrp rig with a antenna. Tunner no issue. Used a ts 50 same setup no issue. Also used a noise Canceling speaker.
I have heard that switching to a shielded ethernet cable between the main unit and head can help alot as well.
They are pulsing voltage to the fan motor to control the fan speed.
Be careful running the negative to the battery. These newer vehicles have a BMS on them. Running anything to the negative bypasses the BMS.
getting the same here in NZ
I gave up trying to eliminate rfi in my 22sv. Tried ferrites binding hood doors bed ect ect. Now I just operate with truck off on an external bat
Open the windows. Solved
I've got some of those ferrite clips so if you need them, hit me up YZI.
Did we just find the frequency of air?
Maybe put a bead on the wires going to the fan motor under the glove box
I wish I wdve got a 7100. Hate my ft710
did you wrap the cable thru the ferrite a few times???? Good to hear you today, 73 de k5vwz
In multiple places, yes
Each turn 10× the power of the ferrite.
Well, that's not good. I have a 2023 Nissan Frontier SV and was planning on installing my IC7100 in it soon. What antenna are you using? Thanks for the video.

Robert, the designer of Tarheel Antennas lives across town from me. Planning on paying him a visit soon.
Where do you get your beads? Gotta link or recommendation? Thanks
