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?

Re: RCI 2950DX Low TX power problem.
With the above settings, you should get 10 watts on AM/FM and 25 watts on SBB. If the power is still low I would changes the finals and the driver. I get 10 watts FM and 20+ on SSB but AM only 4 watts max no forward swing? That still means finals still could be bad? Maybe something else wrong with ...
