Text of report by Thai newspaper The Nation website on 29 September
Newly revived red-shirt [opposition] community radio FM 102.75 based in Bangkok claim the government is interfering with their transmission through signal jamming and the act is a breach against their constitutional right to communicate.
“We have been threatened and this shouldn’t have taken place,” said Pongsak Kongsaena, director of the radio which broadcast to listeners in the northeastern part of Bangkok including Min Buri which is a stronghold of red shirts. “Thai society is fully entering a dark age. Those who hold differing view are being threatened.”
Pongsak said at a press conference Tuesday that the government should cease the jamming and respect the fundamental right of citizens to communicate. He added that the station will lodge a complaint with the National Human Rights Commission.

Having checked the frequency several times today i can hear the station on 102.75 and there appeared to be nothing that i would interpret as deliberate jamming.
However the FM band is full to bursting with activity as the main radio stations operate with about 5 KW on frequencies 87.5 - 88 - 88.5 up to 107.5 and
several hundred low power (a few hundred watts) community stations operate 87.75 - 88.25 up to 108, these stations share the same frequencies in different parts of the city hence interference to reception while driving is pretty much guaranteed.
