LCL 2740 UK (CB27/81) CB radio (Mobile) - VCO adjustment (Covers DNT M40 too)

Richard Shireby, G0OJF, (Grantham, Lincs, UK) discusses & demonstrates the VCO setup procedure on the LCL 2740 UK (27/81) FM CB radio. This radio is electrically identical to the DNT M40, so what is said here applies to the DNT radio as well. Sometimes these sets suffer from the tx/rx relay dropping out during transmission, or 'chattering'. This VCO adjustment cures those snags.
