Do you drive an imported Japanese car?

If you drive an imported Japanese car with a Japanese radio installed, you will be receiving New Zealand FM frequencies via a gadget called a "Band Expander". This is because Japan uses a different FM frequency band from New Zealand and most other countries. At best it's a 'patch-up' solution, and you will occasionally receive interference depending on local frequencies and the size of your band expander. A radio designed for NZ is much the best option. However, if you're going to stick with your Japanese radio, and haven't already worked out how to tune by trial and error, here are our suggestions as to what to do...

Step 1 If Frequency Finder lists your favourite station at, for example, NZ 100 FM, try your Japanese radio at 90 FM. If your station is there, you can see the difference is 10 MHz so you have a 10 MHz expander. You can find your other stations by subtracting 10 from the Frequency Finder frequencies e.g. if Frequency Finder shows your next favourite at NZ90 FM, you'll find it at 80 FM on your Japanese radio.      If this doesn’t work...

Step 2 If 100 FM doesn't show up at 90 FM, next try 88 FM. If you strike gold this time it means you've got a 12MHz band expander. So subtract 12 from your other chosen stations e.g. 88 FM on F.F becomes 76 FM on your Japanese radio.      But, if you still haven't found your favourite station...

Step 3 Subtract 14 from the F.F frequency - so e.g. 100 FM becomes 86 FM on your Japanese radio - this means that you have a 14 MHz band expander. So, subtract 14 from the F.F frequencies you want and that will give you the frequencies on your Japanese radio.

Happy listening.
