Thoughts and Comments by Mike Morris WA6ILQ
All of this used to be on the main Motorola Index page. It was split off and moved to a separate page because it contains useful information, plus it forms a repository for unrelated comments and thoughts.
|Here is a part number for the Quantar power supply fan: ADDA Fans AD0912HB-A73GL-LF. This is a 92 mm x 92 mm X 20 mm fan with the tachometer leads.|
|The Quantar uses an Onan power supply number 3-70506-0000 or Motorola number 01-84906T04. The integrated circuit thermistor in this supply is a Honeywell TD5, Digi-Key Part Number 480-2017-ND. It's about 2100 ohms with 1.55 volts across it at 90 degrees Fahrenheit.|
|The Quantar programming cable (30-80369E31 or E32 depending on which parts
catalog you read) is $68 from Motorola, but it's a simple DB-9 cable.

|Software is RVN5002 for both Quantar and ASTRO-TAC 3000. I'm mentioning this because the ASTRO-TAC isn't mentioned on the R-B Quantar page. It's basically the receiver module of the Quantar sold as a stand-alone receiver, like the old Micor-based Zux receiver / SpectraTAC receiver.|
|If you have a transistor or other part with a Moto logo and a 4-digit number and the book doesn't show a part number try putting "48-86" in front of the four digit part number - then look it up at www.myradiomall.com - or Google it (i.e. a M9102 becomes part number 48-869102 or 46869102. You just might get a hit.|
|The replacement microphone coiled cord for the Mitrek, Micor, Syntor and several others (not the Spectra) is part number 083731M01.|
|Bubble-Pack radio "Privacy Codes": Motorola makes several "bubble pack" models in the MURS, GMRS and FRS lines that have "privacy codes". Here is a translation table that works on most of the "Talkabout" line, it may be valid for others (please let Mike WA6ILQ know at (firstname.lastname@example.org). Of course we all know that PL, DPL ("CTCSS", "DCS") doesn't really "fix" anything, nor does it give you any privacy. And that the tone or code numbers are different between manufacturers, and sometimes between different product lines in the same manufacturer.|
|Motorola microphone manual number 6880309C84: This manual covers the DTMF microphones with the following part numbers: TDN8305A/B, TDN8306A/B, TDN8307A/BSP, TDN8309A/B, TDN8310A/B (DTMF Maxtrac). As of April 2011 this manual was still available for about US$2.10.|
|Motorola microphone manual number 6881085E15: This manual covers the Auto-Dial Touch Code Encoder Palm Microphones with Backlit Keypad with the following part numbers: TMN6169A (DTMF Maxtrac Conventional), TMN6170A (DTMF Maxtrac Trunked), TMN6171A (DTMF MaraTrac with the A2 and A3 heads), TMN6172A (DTMF MaraTrac with the A7 head), TMN6173A (DTMF Spectra Conventional), TMN6174A (DTMF Spectra Trunked), TMN6175A (DTMF Mostar Conventional), TMN6176A (DTMF Mostar Trunked). As of April 2011 this manual was still available for about US$3.66.|
|Speaking of microphones, Motorola made a rather unique one for the California Highway Patrol (CHP) Micor radios that had a two-position rocker-style PTT button with the letters "C" and "S" on it, probably to go along with a dual radio setup. Click here for a photo. If anyone has more information on this unit, please let us know.|
|Can you believe Motorola actually makes a small tool they call a "mini-UHF Connector Wrench"? Well, they do. It's a small piece of spring metal bent in an Omega shape that fits around mini-UHF male connectors so you can tighten and loosen them in tight spaces. Click here for a photo of one in a package. They don't want you to use a pair of pliers. To use it, tighten the mini-UHF connector onto the antenna jack as much as possible by hand, then put this tool over the knurled part, squeeze it until the ends touch, and tighten the connector until the tool slips. The part number is HLN6695A and it only costs $6.00US in the middle of 2012. They include them free with some equipment. Such a deal.|
|Here's the power that one reader's MSF5000 "CXB" repeater draws from the AC line:
VHF: Idle: 57w; 30w: 330w; 50w: 510w; 100w: 700w. As you can see, these stations are rather inefficient (RF power out vs AC power in).
|Anybody want to do an article on the Waris series? (which includes the GP320,
GP328, GP338, GP338-LS,
GP329, GP339, GP340, GP360, GP380, HT750, HT1250, HT1250LS, HT1550, HT1550XLS, GP140,
GP320, GP330, GP328, GP329, GP338, GP339, GP340, GP360, GP380, GP640, GP650, GP680,
GP1280, PTX700, PTX760, PTX780, ATS2500, MTX850, MTX850LS, MTX8250, MTX8250LS, MTX900,
MTX950, MTX960, MTX9250, PRO5150, PRO5350, PRO5450, PRO5550, PRO5750, PRO7150, PRO7350,
PRO7450, PRO7550, PRO7750, and the PRO9150)
Note that Moto marketing screwed up and has a MTX900 model in BOTH the Jedi and Waris product lines. If you are buying a MTX900 make sure which one you are getting. They are VERY different.
