Default Indoor FM boost with no cables?

A single-channel (re)transmitter might be legal here in the U.S. under
Part 15 regulations... but boosting and transmitting everything that
got into the outdoor antenna could really be problematic. You could
end up making reception worse for your flat-neighbors, if the system
you were boosting/repeating interfered with direct reception of the
same signal.



Yes, I have the same reservations about it. In the UK there are legal
small transmitters with range about 500 yards with clear line of sight, and I
was thinking I'd need a lot less capability and thus be safe but I don't know
what the safety margins for legality and polite usage would be, if any.

One thing I noticed tonight was that the transmitter signal strenth is
increased perhaps due to maintence work beign completed or halted for the
week end. There's not a lot of difference, but enough to indicate that just
6dB of boost might be plenty to solve this if it's safe to do it.
