Seller: spectrumcomms ✉️ (5,908) 100%, Location: Dorchester, GB, Ships to: GB, Item: 282230041141 CB EU band add-on board SC26L for UK rigs with LC7137. This board is a complete synthesizer producing the EU (USA mid block) channels for a UK81 CB FM rig which uses the LC7136 or LC7137.  The board includes an eprom to pick up the BCD codes of the LC7137 and convert them to the 7 segment codes used by an LC7132 synthesizer IC.  It includes a connection to the 10.24MHz oscillator of the main board synthesizer and provides an offset for that to put the EU/USA channels precisely on frequency. The board also includes its own loop filter components so the voltage controlled oscillator control voltage is only switched between existing filtered level and add-on filtered level.  This avoids the synthesizer whine characteristics of using an LC7132 fitted piggy back on the LC7137. the board measures 2.1x1.7x0.9 inches including the 7805 regulator so will only fit in the larger older style rigs.  It is possible though to soder the 7805 to the underside of the PCB and reduce the overall height to 0.6 inches. If you wish to purchase multiple items or products, click Buy on each then request an invoice.  I will send an invoice without multiple carriage costs.
