IC900.5 #: 79969 S7/Vendor Support 16-Aug-88 23:54:53 Sb: IC900.MOD Correction Fm: Larry A. Bronstone 72667,3201 To: sysop (X) I just downloaded the file IC900.MOD and noticed a few errors. 1. On the 220 band install a diode at 2C not 1C (1C is for the 144 band). 2. The diagram showing the stock matrix layout has a diode at 2H. The diode is actually at 3H. As a point of clarification removing diodes 4B, 3B and 3D gives maximum receive coverage on all bands. The diode that ICOM uses on their matrix board is 1SS211. The matrix is inside the REMOTE CONTROLLER along with all of the memory settings. MINI-REPEATER instructions (addition of diode 1A on matrix and (S1 & S2 both in position 2 - interface unit A). 1. Both frequencies in the MAIN and SUB bands must be in the SIMPLEX mode. 2 The LOCK switch acts as the repeat on/off switch. With the LOCK switch activated, the LOCK indicator will flash. 3. When a signal is received on the SUB band it will be retransmitted on the MAIN band. If a signal is received on the MAIN band, the unit will reverse the MAIN and SUB frequencies, then retransmit on the MAIN band. 4. If either of the band units have DUP activated, the LOCK switch will function as normal. The LOCK switch disables the front panel controls when activated even in repeater mode. 5. The MINI-Repeater operation will also operate if the optional tone units are installed, however, both bands to be used in the Mini-Repeater operation MUST have the option installed and activated.
