Please fill in your full name including your first name, middle name and last name when making the paymentĢ. Can I use more than one Band Expander together to vie me a full frequency range ?ġ. Is it important to run FM Band Expander on 12 V ?ġ0. It is also beneficial if the center core is constructed of many copper strands to improve strength and flexibility.ĩ. Using a wrong impedance eg.75Ohm cable which is used in some Band Expanders resulting in poor reception.

Is it important to use right aerial leads ?Īerial leads must have an impedance matched to car radio and aerial system. This can be very expensive if parts are available.Ĩ.
#How to install car radio band expander software
Yes there is a small number of sets that can be changed, they require changing the microcontroler’s software and or replacing tuner pack. Can I change the car radio set internally to new FM Band ? Compromising filter’s performance will result in more interference occurring. Unfortunately most countries frequency range is fully utilized, resulting in large numbers of Communication Equipment operating above and below FM Band.

It is essential requirement in rejecting unwanted frequencies interfering with the shifted FM Band. radio interference, weak signal, inadequate bandwith. They may work but there can be or a number of unsatisfactory performance problems. No the Band Expander does not change the radio’s display, it only changes the original frequency once tuned, program into pre-select memory. Does the Band Expander change the Car Radio Display 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.Ĥ.

Operating well below receiving frequencies producing blank-spots on frequency tuning range. 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.Ĭommon 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.Ĭommon to all Band Expanders frequency harmonics generated by Crystal oscillator. Is it important to run Band Expander on 12 Volts?īand Expander is designed to run on 12 Volts. FQA: Listed below are a number of frequently asked questions.ġ. 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. Please ensure the unit is clear of any moving pedals, heater controls etc. Your FM Band Expander is earthed via your existing antenna. This will ensure power is supplied while radio is in operation. Preferably use the accessory feed that supplies the radio. Your car using the black quick tap connector supplied. Connect the red power lead from the FM Band Expander to +12 volt power supply on Plug the male plug from the FM Band Expander into the antenna socket on the radio.ĥ. Plug the antenna lead into the female socket on the FM Band Expander.Ĥ. Disconnect the antenna lead from the back of your car radio.ģ. Remove radio from dash or obtain clear view of antenna input socket to radio.Ģ. To obtain maximum efficiency from your unit please follow the simple installation instructions below:ġ. The supply for 12V DC (+) voltage to the red wire, negative to the black wire. It attaches in-line with the antenna input on the stereo and will receive the stations up to 108Mhz, different from Japan radio frequency from 76Mhz to 90Mhz. The radio band expander enables the orignal equipped radio in Japanese imported cars to receive radio transmissions in other countries.It achieves this by shifting the transmission frequencies into the band that the Japanese radio will detect. Shift the Japanese version in line with the wave band universal Japanese car But in other countries you need as much as 108Mhz. In Japan, radios are made to receive in the 76Mhz to 90Mhz band.
