Following further investigation I checked continuity from the band switch to L7 the aerial coil that's fine a 220k resistor was reading 290k so I changed that on the coil the 150pf cap read okay. Next L16 in RF1 the switch to the coil is fine another 220k was reading high 270k so changed that. The coils L25 and L35 are ok as are the band switch to the coil there is improvement but no signals .. Band six works with a LF rejector that is only used on band six could the issue be that ?.
