There is a filter that grounds the input at the 27-30 mhz freq. The filter
needs to be by-passed. This filter is sometimes NOT shown on the schematic.
It is a small PC board about 1" square with a toroid coil and a couple caps
on it. Bypass that or remove it and you'll be good to go on 10 meters, also
be sure the bandswitch mod has been done. You sometimes need to advance the
stop on the bandswitch and tap the coil for 10 meters as well. Good Luck
