Ron, The C73GSB-3145B is a fully-optionable, intermittent-duty base station that should be equipped with the TLD2532A 110 watt PA and the TPN1191A power supply. The number TRN5299 identifies a chassis assembly, not a power amplifier, and TPN1189 identifies an auxiliary regulator chassis, not the power supply. I thought that Micor stations were hard to figure out, with multiple part numbers appearing on many components, but the MSR2000 stations are worse. The power amplifier alone has separate numbers for the heat sink, the chassis, the power control board, the PA board, and the mounting brackets. In some PAs, there are frequency-sensitive modules like the harmonic filter that are buried inside, and these sometimes must be modified for optimum operation in the Amateur 2m band.
The two manuals you need are the 6881061E50 VHF Base and Repeater Stations Service Manual, and the 6881061E40 Control and Audio Instruction Manual. Alas, the E50 manual is out of print, but the E40 manual is still available from Motorola Parts for about $60. I have added the E50 scanning task to my ever-growing "to do" list. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Ron Wright Sent: Friday, November 30, 2007 6:52 PM To: [email protected]; skipp025 Subject: Re: [Repeater-Builder] Re: MSR-2000 Skipp & Eric, I forgot one important thing obviously. It is a VHF MSR2000 Model C73GSB-3145B which is a 110 W base station. Included is TRN5299 PA, TPN1189 power supply and TRN5080 METER. It is on 154/159 MHz. I plan on using for Ham band and also add UHF receiver for control since it has slot for second receiver. I am assuming the second receiver will just plug in. Any help or source for the manuals would be appreciated. 73, ron, n9ee/r >From: skipp025 <[EMAIL PROTECTED] <mailto:skipp025%40yahoo.com> > >Date: 2007/11/30 Fri PM 08:09:48 CST >To: [email protected] <mailto:Repeater-Builder%40yahoogroups.com> >Subject: [Repeater-Builder] Re: MSR-2000 > >The normal route is two manuals to service the Standard US >Version MSR-2000.
