PB1000-14MHz Technical Specifications |
Frequency input
range 90 - 108 MHz - Area specific- model
Output 76 -90 MHz Ripple in pass Band <6dB Isolation Sensitivity |
Blank
Spots Frequency harmonics generated by Crystal oscillator operating well below receiving Frequencies producing blank-spots on frequency tuning range. This is common to all available Band Expanders on market. Those blank-spots causing receiver ( car radio) to look as car radio was muted. PB1000( 14MHz shift) has blank-spot on 98MHz. FM station broadcasted exactly on 98MHz, will be masked by Band Expander's Harmonics. FM Stations double-ups FM Stations double-ups for 14MHz shift will occur if there are two FM Stations broadcasting 14MHz apart, in the same location. |

Receivers maximum sensitivity for 26dB SINAD. |
INSTALLATION INSTRUCTIONS PB1000-14MHz
|
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. Also available units with reverse aerial leads, units for 24V systems and adapter plugs for Nissan car radios. |
FM Stations Broadcasting from 90 to 104MHz (excluding 98-blank-spot) will be displayed subtracting 14MHz from FM Station Broadcasting frequency. FM Stations Broadcasting from 104.1 to 108MHz will be displayed subtracting 28MHz from FM Station Broadcasting frequency. ( Do not use PB1000-14MHz to receive FM Stations Broadcasting on 98MHz) (FM Stations double-ups will occur if there are two FM Stations broadcasting 14MHz apart in the same location.)
|
Manual Tuning For manual tuning the same operation applies as for digital ( see above). In some instances you may have to adjust the antenna trimmer on the radio set to fine tune the AM Frequencies. Simply subtract frequency shift from desired Station frequency as per examples and manually tune. AM frequencies are by-passed by P.B. 1000-14MHz, so can be tuned normally. |
Technical Tips: |
Radio display still operates from 76-90MHz. The Band Expander plugs
into the aerial socket and converts incoming frequencies, fooling the
radio into thinking it is coming from 76-90MHz. E.g.: 97.4FM will display
83.4FM (frequency shift 14MHz). Frequency from 100 to 108MHz (88 - 108MHz
models only) will shift two times the shifting frequency E.g.: 107.4MHz
will display 79.4MHz (frequency shift 14MHz). Power connections for red wire. The best way to find 12V is to use a volt meter. (Instead of a light probe) which can cause serious damage to sensitive electronic equipment, and does not give a true reading. 24V vehicles most often have a 24-12 volt reducer, as the car stereo runs on 12V. There are units available for truck radios that run on 24V only. If your vehicle is fitted with a Diversity Antenna System connect the Band Expander to the main aerial and disconnect the sub-aerial. We recommend fitting a Band Expander on each aerial input, as the sub-aerial is designed to operate when the transmitter signal is to strong for the radio input. This happens when the vehicle is in close proximity to the transmitter, e.g.: Radio switches from main aerial to the sub-aerial then back. Main aerial lead is identified by the following. Lead width is the largest. Standard aerial plug connected to the ground plain aerial. e.g.: Electric aerial - manual aerial. Sub-Aerial is usually located in the windscreen glass. There are vehicles that have both aerials in the windscreen glass, for these vehicles we strongly recommend fitting two Band Expanders, as the reception can be directional without a ground plain aerial. Connecting the Band Expander to a non standard plug by use of adaptor plugs or cut and connect a standard aerial male and female plugs into the aerial lead, do not cut aerial leads of the converter, as this will alter Radio Telephone Filter setting in the converter. The Band Expander can be installed anywhere in the aerial lead, behind the set or at the aerial lead socket. e.g.: Nissan vehicles, but check to make sure that the Male aerial socket of the Band Expander goes to the radio set, as there are some vehicle manufactures that have reversed these sockets, converter aerial socket Male output 76-90MHz to radio. Female aerial socket input 88-108MHz from aerial. International FM Band's bandwidth is 20MHz (88MHz-108MHz) compared to Japanese FM Band's bandwidth only 14MHz wide (76MHz-90MHz). Larger bandwidth means larger number of FM stations, so converting entirely International FM Band to Japanese FM Band must contain some compromises. All FM Band Expanders available on market are compromised more or less to accommodate frequency shift. When selecting Band Expander, attention must be paid to FM station double-ups, blank-spots and RT interference (Communication Equipment operating above and below FM Band). We can provide you the suitable frequency shift option for your requirement. Please supply us, all your local radio station frequencies. We will run a program working out best suitable Band Expander. I hope these technical tips will help. Thank you for purchasing our product. Enjoy listening to your radio station |
