Yaesu built the FT-301 in two basic flavors: a 10W qrp version, and a
100W qro version. I don't know if it is still legal, but the difference
between the two is the addition of a "booster unit" attached to the rear
of the transceiver. This "booster unit" is connected to the transceiver
via 2 bnc coaxial connectors, and a multi-pin rack and panel connector.
The "booster unit has no tuned circuits, just some wide-band coupling
transformers on the input and output. The bandswitched tuned circuits
are all in the basic rig (I assume the power-handling capability of these
circuits is the same in both versions). The qro rig can be converted to a
10W rig simply by removing the booster unit, and adding a short coaxial
jumper. This might be a viable approach to making a qrp kit that could
be legally changed (by the owner) to a qro rig.
Just some thoughts......
