Noticed activity on this frequency while listening for traffic on 4630 kHz USB. Seems to be similar signal strength as the possible Portuguese / Italian / Spanish (

) language signals heard on 4630 kHz. Aircraft traffic on nearby frequency 4666 kHz USB.
I
think what I'm hearing is Italian or maybe Portuguese with a different accent than I'm used to hearing. I don't think its Spanish (if it is, I've never heard this accent before).
