Landcruiser Diesel & HF Radio

Quite a lot on LC 100's and HF interference. Do a search on this site.

You are not alone - I have the same problem - same motor - same radio - I've put it in the too hard basket - it was chronic in my TD Jackaroo too - many makes report the same problem - the radio has "big ears" and there are many gadjets and circuits on the car only too ready to send out the feral signals. A lot of VKS737 members do their comms early and late in the day while static - comming while mobile is a luxury that many members don't expect - that said, mobile comms can be very good at times, even with noisy electronics - HF does spring agreeable surprises at times.

The Interference comes from the high-energy pulse going to the Injectors - if the S meter goes to full strength then the only signals you will pick up will be extremely strong ones.

If the Installer knows what he is doing he should know which vehicles generate high noise and warned you that a basic installation will not allow any reception while the engine is running.

If you just wanted an installation that only worked in camp you could have saved all the money on the installation and just run the battery leads to an Anderson Connector at the battery and used a long wire antenna.

Unless he explained to you that this installation would not work with the engine running, this installation is "not fit for purpose" under the trade practices act.

Apparently this noise can be reduced by installing ferrites on the Injector Leads.

I will soon be starting installation of HF in my electronically injected Diesel Pajero.

This might give you some ide of the problems you face.

Th- Thr Thre Three and a half thousand!! Is HF radio really the way to go when you can buy a sat phone these days?? I dont know much about Sat phones but they must be a better deal than HF if you only intend to use in an Emergency?? Michael

have tou tried removing your dtronic?

I have a Barrett 950 + identical motor + identical noise problem.
I got a headache thinking about all those solutions with ferrites and capacitors and earthing etc etc etc and I don't like to chop into the reliable factory wiring.
I went down the path of fitting a noise suppressing speaker. Cost about $350 from memory from Electric Bug in Adelaide about 2 years ago. On the first setting, it reduces the extra noise to an easy listening level; On the second and subsequent levels it introduces too much distortion. But when stationary (and the fridge and fluors are turned off :-)) it cuts out a lot of the extra background noise, so I've grown to like it.

Its a pretty expensive solution, but very simple to install.

Thank you everyone for all of your fedback and suggestions. I wanted the HF for the contact with other 4wd travellers and road conditions etc as well as an emergency situation (sat phone only gives you an emergency contact) , looks like thats what I have just need to be stopped to use it. Thanks again...
