If necessary, adjustment of the frequency shift should be performed separately for each modulation mode, rotating the selector dial modulation. Using a dial channels and clarifier introduce the desired value. Radio came just in adjustment mode, and the display show the message SHOULD BFXXX (where XXX is the numeric designation of the setting, not the frequency). Then press one after the other buttons RB, AN / ANL, DW Press the 'FUNC' button and holding it turn on the radioĢ. So what to do to align the frequency display with real?ġ. Typically helped here knob clarifier, which tune the 'ear' to the frequency of our interlocutor. 26.425.00 MHz and our respondents, who are also on this frequency can not hear us, and we hear them with great difficulty. This happens when the frequency on the display does not match the frequency of transmission or reception. It can happen that your radio is out of tune. I wish to make this topic a know-how for anyone who want do this mods.īut, for now, I know only how to mod a CLARIFIER and tune RX/TX In Poland one of CB service offer this modifications (translation from Polish)ġ/ fine-tuning of the track receiver / transmitterĢ/ installation of quartz filter and IF 10.695KNKTR - improving the selectivity / (Im not sure that I can buyģ/ installation of an active filter IF II Channel Guard - to improve selectivityĤ/ improving the tone of the narrowed down receiver - more trebleĥ/ improving modulation AM - louder broadcastingĦ/ adding a treble in a transmission path - the more acute (louder?) modulationħ/ change the functions CLARIFIER in emissions USB / LSB - not muted reception when tuningĩ/ Digital measurement system calibration SWR - more reliable measurement at higher transmission power I would like create this topic for all owners CRE 8900 / Alinco DR135DX.
