To: Repeater-Builder From: Eric Lemmon WB6FLY The MTR2000 does not use the traditional Motorola numbering scheme (like C73RCB3106BT) to indicate the band and power level. You have to decode a bunch of cryptic Field Replaceable Unit ("FRU") numbers in order to identify exactly what you really have, and these labels are not always visible! Well, here you are... a "Rosetta Stone" list of FRUs. The following list of FRUs (Field Replaceable Units) should be helpful in identifying the frequency range and power of an MTR2000 station: STATION CONTROL MODULE: CLN1201 or CLN1465 or TCN6273 - All stations, all bands. RECEIVER MODULE: CLN1211 or CLN1466 or TRD6431 - 132-174 MHz with internal preselector CLN1212 or TRD6411 - 132-174 MHz without internal preslector CLD1020 or TRX4013 - 335-405 MHz CLN1213 or TRX4014 - 403-470 MHz with internal preselector CLN1214 or CRX4004 - 403-470 MHz without internal preselector CLN1215 or TRF6631 - 806-825 MHz CLF1270 or TRF6632 - 896-915 MHz EXTERNAL PRESELECTOR: CLN1216 - 132-154 MHz CLN1217 - 150-174 MHz CLN1218 - 403-433 MHz CLN1219 - 433-470 MHz EXCITER MODULE: CLN1233 or TTD6301 or CLD1200 - 132-174 MHz CLD1030 or TTX4013 - 335-405 MHz CLN1234 or TTX4014 or CLE1450 - 403-470 MHz CLN1235 or TTF6521 - 850-870 MHz CLF1280 or TTF6522 - 935-941 MHz RF POWER AMPLIFIERS: CLN1224 or TTD1791 - 132-154 MHz, 100 watt CLN1225 or TTD1792 - 150-174 MHz, 100 watt CLN1226 or TTD1781 - 132-174 MHz, 40 watt CLN1227 or TTD1921 - 132-174 MHz, 30 watt CLD1010 or TTX1003 - 335-405 MHz, 40 watt CLN1228 or TTX1010 - 403-435 MHz, 100 watt CLN1229 or TTX1020 - 435-470 MHz, 100 watt CLN1230 or TTX1004 - 403-470 MHz, 40 watt CLN1231 or TTX1054 - 403-470 MHz, 30 watt CLN1232 or TTF1601 - 850-870 MHz, 75 watt CLF1260 or TTF1602 - 935-941 MHz, 75 watt EXTERNAL DOUBLE CIRCULATOR: CLN1207 - 132-146 MHz CLN1208 - 144-160 MHz CLN1209 - 158-174 MHz CLN1210 - 403-470 MHz CLN1279 - 850-870 MHz CLF1290 - 935-941 MHz AUXILIARY I/O CARD: CLN1206 or CLN6698 WIRELINE CONTROL CARD: CLN1203 or TTN5067 POWER SUPPLY: CLN1220 - AC Input 500 watt, for 75 or 100 watt power amplifiers CLN1221 - AC Input 250 watt, for 30 or 40 watt power amplifiers CLN1222 - 28 VDC Input, 500 watt, for 75 or 100 watt power amplifiers CLN1223 - 14 VDC Input, 250 watt, for 30 or 40 watt power amplifiers Note: Both the low power and the high power AC-input supplies use switching technology, and operate on anything from 85 to 264 VAC, 47 to 63 Hz, without any adjustment.
