Product description

Car Radio FM Band Expander 3 IN 1 Unit 16MHz, 18MHz and 20MHz

High quality crystals in all our fm band expanders to make sure you only listen to the quality sound, not the cheap one !

In Japan, radios are made to receive the frequency 76Mhz to 90Mhz. But in other countries you need as much as 108Mhz.Our electronic fm band expander EXPANDS the range of a Japanese car radio up to 108 Mhz.

Installaion:

To obtain maximum efficiency from your unit, please follow the simple installation instructions below:

1. Remove radio from dash or obtain clear view of antenna input socket to radio.
2. Disconnect the antenna lead from the back of your car radio.
3. Plug the antenna lead into the female socket on the FM Band Expander.
4. Plug the male plug from the FM Band Expander into the antenna socket on the radio.
5. Connect the red power lead from the FM Band Expander to +12 volt power supply on your car using the black quick tap connector supplied. Preferably use the accessory feed that supplies the radio.This will ensure power is supplied while radio is in operation.

NB. Your FM Band Expander is earthed via your existing antenna. Please ensure the unit is clear of any moving pedals, heater controls etc. If your vehicle is fitted with a Diversity antenna system connect the Band Expander to the main aerial and disconnect the sub – aerial, but we recommend fitting a Band Expander on each aerial input.

FQA:

Listed below are a number of frequently asked questions.

1. Is it important to run Band Expander on 12 Volts?
Band Expander is designed to run on 12 Volts. There are available 24 Volts Band Expanders, also most 24 Volts vehicles have a 24 Volt to 12 Volt converter to run the stereo system.
2. What are Radio Station Double-Ups?
Common to all FM Band Expanders are Radio Station Double-Ups caused by shifting 20Mhz of bandwidth into 14Mhz of bandwidth ( 88Mhz to108Mhz shifted into 76Mhz to 90MHz ) and overlapping Japanese band FM Band and International FM Band ( 88Mhz to 90Mhz ) eg: Radio Station 105.4Mhz and 95.4Mhz will both tune into the car radio at 85.4Mhz.
3. What are Radio Frequency Blank Spots?
Common to all Band Expanders frequency harmonics generated by Crystal oscillator. Operating well below receiving frequencies producing blank-spots on frequency tuning range. For 10Mhz frequency shift Blank Spots are 90 and 100Mhz for 12Mhz shift they are 96 and 108Mhz for14Mhz shift 98Mhz for 16Mhz shift 96Mhz and 18Mhz shift is 90 and108Mhz.
4. Does the Band Expander change the Car Radio Display
No the Band Expander does not change the radio’s display, it only changes the original frequency once tuned, program into pre-select memory.
5. Are FM Band Expanders all the same ?
No they are not all the same. They may work but there can be or a number of unsatisfactory performance problems. E.G. radio interference, weak signal, inadequate bandwith.
6. Is Radio filter important?
It is essential requirement in rejecting unwanted frequencies interfering with the shifted FM Band. Unfortunately most countries frequency range is fully utilized, resulting in large numbers of Communication Equipment operating above and below FM Band. Compromising filter’s performance will result in more interference occurring.
7. Can I change the car radio set internally to new FM Band ?
Yes there is a small number of sets that can be changed, they require changing the microcontroler’s software and or replacing tuner pack. This can be very expensive if parts are available.
8. Is it important to use right aerial leads ?
Aerial leads must have an impedance matched to car radio and aerial system. Using a wrong impedance eg.75Ohm cable which is used in some Band Expanders resulting in poor reception. It is also beneficial if the center core is constructed of many copper strands to improve strength and flexibility.
9. Is it important to run FM Band Expander on 12 V ?
Band Expander is designed to run on 12 Volts. There are available 24 Volts Band Expanders, also most 24 Volts vehicles have a 24 Volt to 12 Volt converter to run the stereo system.
10. Can I use more than one Band Expander together to vie me a full frequency range ?
No. It would result in poor reception.
