After the noise begins, a VOA News story in MFSK16 will first be transmitted at full level, then reduced to -6 dB, then reduced to -12 dB. I will probably lose many of you when the level is reduced to -12 dB, but please stay tuned: the audio level will soon be restored. > Please note that noise that is mixed with MFSK text as part of the VOA Radiogram production is not an ideal simulation of co-channel interference. This is because real co-channel interference involves two (or more) transmitters at different locations and with different propagational characteristics. =============================================================== .....reception results from June 15th 2013 with IC-R75/Boomerang on 17860 kHz, 16-16.30z No problems, despite the intended noise..... http://www.rhci-online.de/VOA_Radiogram_17860kHz_2013-06-15.htm qth: D-06193 Petersberg /Germany 73+55 roger
