I don't believe it's going to be quite that easy.
The TopTen decoder either sinks or (with a simple mod)
sources 12 vdc to a particular output pin depending on
the input signal. You need to confirm exactly what type
of band input the Yaesu amp requires. I think it's looking
for a logic signal, in which case the band decoder won't
work directly. See the decoder schematic at:
