Hi Carlos,

When you say 'no voltage'  measured
on Q6, can you be more precise?

The collector of Q6 should measure
about 12 V DC whether in TX or RX.
The base and emitter voltages will
be zero until the transmitter is
keyed on.  The base voltage depends
on the selected mode (CW or SSB),
and I recommend measuring in CW
mode.  The emitter voltage will be
roughly 0.6 V below the base voltage
once the transmitter is keyed.
