The return on my Spanish Sporadic E reception reports is quite poor. Especially when you compare it to the response rate of the Italian stations (over 50%). But at least my report to Pop Lasser FM from Valencia, Spain, was answered with a kind reply from the technical department. I sent my report to popradiofmvalencia@gmail.com .
Pop Lasser (the RDS display shows Laser by the way) broadcasts from Valencia with only 2 kW. I heard them with pop music and local commercials from Valencia, which – in addition to the PI code/RDS – helped the identification.
