Re: 98vhp no modulation

Ok I got Tx back the L44-43-42-40 was out of align. But I still have no modulation? Plus I get a 120+ watt deadkey on SSB? Rx is fine. ic7 is good.

Re: 98vhp no transmit

Looking at schematic I'm getting 6v to L31 and C200 but from C200 to c201-c202 and c197 not getting the 6v power? Would that keep me from getting Tx out? If I touch them other coils with meter lead it gets a signal reading on my other radio but no RF out?

No freq. counter plug on back. Very common board I never seen wires on them before? Probably some kind of mod?
