First wide data mode i ever used , long time ago ..had a qso on 7 meg with cw and rtty all on in the same slot ..it printed fine .. amazing IZ8BLY prog .. dont know how good it is against the new progs . but still works ..
ran some tests on 500 , and found it dident do so well down there with low signal levels .. mfsk16 > olivia > then mt63 Use the tune tone and set under the alc point ..or the drive will try to level the signal G .. --- In digitalradio@yahoogroups.com, "José A.
