> The relationship of frequencies indicates a carrier modulated with a signal of about 18 ... 20 kHz. The amplitude relationship with sidebands half as strong as the carrier means 100% modulation. Really no modulation? Or just no speech but a lot of background noise and wide open mic gain? > > Uli, DK4SX > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of DAN COTSIRILOS > Sent: Dienstag, 4.
