Eric, The C44CXB7106BT model number breaks down as follows:
C = Compa-Station 4 = 40 watt output power 4 = 406-512 MHz Range (but, see below) CX = MSF Digital Capable B = 120 VAC Primary Voltage 7 = Programmable Squelch 1 = 25 kHz Channel Spacing 0 = N/A, always zero 6 = Tone Remote Control B = Version Code T = Repeater Station The model number does not tell you what frequency range it is: Range 1, 403-435 MHz, or Range 2, 435-475 MHz. Look for a number stamped on the power amplifier; if the number is TTE1521A, the station is in Range 1, and if the number is TTE1522A, it is Range 2. You can also look for a number on the RF Tray. If you see the number TUE2001A, it is Range 1, and if it is TUE2002A, it is Range 2. The Basic Service Manual for the MSF5000 is Motorola Part 6881092E05, and is still available from Motorola Parts for about $45. Unfortunately, the detailed service manual for UHF stations, 6881092E80, was recently cancelled and is NLA. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Eric M.

Inside on the back is what looks like a motorola part number, which is C44CXB7106BT, can anyone out there tell me what frequency range this will operate under or if this isn't the right number tell me where I can look on the repeater. Thanks, Eric VA3EAM
