Hello again all; I have an associate who has been using a TCM3105 modem chip in packet radio applications. These are no longer available at an affordable price. Does anyone know whether someone has already done this in a PIC, or if there is a similar chip which will do the job? We also are interested in a PIC based clock which displays two timezones, local and GMT time. Has this been done, and if so can someone please point me in the right direction? Cheers ______________________________________ Ken Parkyn email: K.Parkyn@sct.gu.edu.au Office of Technical Services, Electronics Workshop GRIFFITH UNIVERSITY Nathan Qld.4111 Australia P.O.Box 185 Ph:(07)3875 7289 Fax:(07)38757151 ________________________________________
