Yeah it's legal to listen, no problem, but back in the 50s most ham radios were split into two separate parts, the receiver and the transmitter. I'm assuming you have both
>Able to broadcast
More difficult. Assuming you live in the US, 1.5kw is the legal maximum power an amateur radio transmitter can have, meaning that you're still in the clear. However, you'd need an amateur radio license and only then would you be legally allowed to broadcast on certain frequency bands only. Not sure what frequencies your radio actually has though, it may or may not cover the amateur radio bands of today because they changed since the 50s.

Depends on where you start blasting nigger, technically it's illegal everywhere but the FCC tends to care less about the lower frequency amateur bands (1800 kHz - 7300 kHz) and doesn't give a shit at all about the CB bands (~27 MHz). Note that it is very easy for somebody to find where you're broadcasting from, especially if you're pumping out 1500 watts, so don't expect to be hidden at all and for grumpy hams to knock on your door if not the FCC themselves.
Look into getting an amateur radio license if you're interesting in transmitting, anon, it's a fun hobby. Pics of it would be great to see, from the looks of it you've got yourself a pretty rare beauty there
