Part 95.303 provides the a clear definition on the various classes of stations for all subparts of Part 95 radio services.

All stations (radio devices/equipment units) connected to an antenna that is affixed to a stationary structure (tower or building) are fixed bases because they are not and can not operate in transport (be moved at any given time) thus is a fixed location and is a base operated equipment. A radio device/equipment) connected to an antenna affixed to a vehicle/vessel/aircraft that can be in transport are mobile units. By rule definition of Part 95, Subpart E, any fixed base that communicates with another fixed base would be defined as and be operating as a fixed station thus must operate pursuant to Parts 95.1763 (a) & (c) and 95.1767 (a)(2). The type of radio equipment (table top radio equipment as opposed to a radio that is normally hanging under a dash/installed in a vehicle) does not have any bearing on the station class of operation. It is based/defined on how/where the radio device being operated and the antenna mounting.

There is no such thing as Interference eliminator codes that Motorola ever used. Anyways, DPL and PL do not eliminate the so called interference it just keeps you from hearing the audio/noise of the interference source not eliminate it. To answer your question regarding are the old Motorola radios compatible with GMRS repeaters? Maybe and maybe not. Depending on the model/series of the old Motorola radios, most likely the GMRS Repeater(s) is/are operating wideband than there would not be a problem, today. A small majority of the GMRS repeaters operate narrowband and depending on the model series of those old Motorola radios, they could pose a problem if they can not operate narrowband with a narrowband operated repeater. Although, you will still access the narrowband operated repeater with a wideband radio, the audio quality will not be optimum. What Motorola⁹ model/series radios are they?

Multi-band antennae are compromises and not ideal when it comes to great distances. It's best to use antennae specific to your operating band for optimum performance and for the farz you're trying to achieve.

It is my understanding that that Rubicon guy is really not a Rubicon guy and he is really a Nissan guy with a Chinese made Jeep Key Fob. Real Izarubicon people drive Rubicons with real American Jeep Keep Fobs.

Under the same operating parameters/conditions, a HAM radio/frequency won't make any difference or be anymore successful.

Make and model of the equipment?

The CDM series radios were programmed by CPS and not RSS thus a 32-bit XP operating system is required. As for having a DOS machine for the older model radios, I had a Pendium XP laptop reconfigured as a DOS with DOS 6.2 and it works great for my HT1000, MT2000, and Visar radios. However, the clock speed is too fast for Analog Sabers, and the various Radius model radios. The RSS goes through the motion of reading the codeplug but will not save the codeplug file after the read.

You're going to get a lot of warbles and wha-whas and not understand anything being said.

It would depend on what the resonate freq is for the antenna and cable. An antenna analyzer will give you that info.

A telephone connection refers to being connected to a telephone "switched" system i.e. a dial up line. Telcom RTO and pieceout (dedicated) circuits, and internet connections are not part of the telephone switched system.

You were hearing traffic on a linked repeater that is linked with a network of other repeaters. Most linked repeaters will utilize two different input tones/codes, one for local repeater mode only and one for the linked network mode. This could be your issue.

And with a real commercial quality radio the radio would immediately go into the CSQ mode when you remove the mic from the holder/clip so you can automatically monitor for other traffic on a community repeater.

The 2.4:1 is less than 3.0:1 so it'll be fine for communicating between people on the trail. It may suck a little if you're trying to communicate with someone at great distances. One of the reasons why the Laird has a higher VSWR is because the transmitting frequency is not matching the tune of the antenna. The antenna may need to be trimmed and for GMRS I would tune/trim it for 465 MHz.

I wouldn't buy any cable from Amazon. Go with M&P or Times Mirror.

OTTO is an excellent product. Klein Electroncs and Planet Headset offer some decent products. Both have several options for the accessory connectors to match the various radio models.

Transmit (encode) with the Travel Tone and set your receiver for CSQ, and operate simplex from your vehicle and save the portable radio batteries as long as you can. Scrap the repeater idea. The repeater more than likely will require AC power which may not be available or if your repeater is DC operated than you will still need AC to charge the battery. Too much power consumption and battery up keep to worry about. Of course this is in case if the fan can't operate due to the public power system being off-line for a long period of time.

If you're considering a Motorola Repeater Station for your project, get something a little more modern like a Quantar with a professional quality duplexer like an EMR Corp type quality and a Laird FG4603 basestation antenna. You'll wish you did in the long run if you go cheap and use crap equipment. There is a reason why public safety agencies do not use consumer and amateur radio grade equipment on their systems.

Also, there are criminal statutes with severe penalties to falsely report emergencies by any means.

Let it rip with the questions. One person may not have all the answers but all together you should get your questions answered so fire away.

From what location and to which repeater?

Did you read the FCC Part 95 rules and regs before you acknowledged by signing the license application stating that you are familiar with said rules? If so, then you should be familiar with which freq of the paired frequency should be the transmit freq to the repeater and which freq should be the receive freq from the repeater pursuant to Section 95.1763 sub sections (a) and (c).

What is your concern or fear if you decide later that you don't like GMRS and what does the HAM registry have to do with GMRS?

Try a Ram Mount RamCan and wrap industrial strength Velcro strips around the portion of the RamCan that is placed in the Cup Holder

Not to be confused with "CG" and "QC" but are the same thing under a different marketing name for General Electric (GE)/Ericsson/MaCom and RCA respectively. CG meaning Channel Guard and QC meaning Quiet Channel.
