Re: ARLA/CLUSTER: Radioamadores alemães detectam transmissões não autorizadas no segmento de amador de 144 MHz

[Hugo Barata]

Boa noite.
Curiosamente talvez pelas esporádicas que tem havido em VHF já por
varias vezes escutei nos 144.010Mhz e em 144.0125Mhz nestes últimos
tempos sinais talvez relativos a este post.

Será que alguém já escutou algo nestas duas frequências nos últimos tempos??
