Found a pirate on Alicante SDR tuner on three frequencies spaced only 0.1MHz apart from eachother.
(on this tuner here:) https://campello.fmtuner.org/
....Seems to be using three different transmitters on 106.0, 106.1 and 106.2 all at the same time from the same area.
No idea what the name is as I don't understand Spanish but if anyone has any more info...

106 empty at the moment .1 and .2 sounds a bit professional for a pirate unless it was something else you heard ? Los classicos which must be the classics.. and a long advert type speech with music under. Kind of pop trance music was being played.

Last night 106.0 was a silent carrier with what sounded like them moving cables etc around as their hum got suddenly much louder and quieter and louder again, but I've not it checked today.
....Was hearing exactly the same thing on 106.1 and 106.2 all out of sync with each other so definitely different rigs on across Alicante area.
None of them have RDS and looks like only 106.2 is in stereo but was overdeviating a bit.

A lot of expense and effort to go to for use of 3 frequencies

You are the SDR detective.

OK so a quick update and after some digging I've burst my bubble now and discovered it's some legal Youth project station thing and not a pirate. So false alarm and dammit haha.

....With the hums in the background, silent carriers and policy of the same nonstop music like hard techno trance stuff I thought it has to be a pirate! But sadly not.

Still shows good ears for the unusual.
