Default simple ham question

OK, i'm quickly getting overwhelmed with the information online, and i need a simple answer... i'm hoping someone can simply say "get a tappaninski 9250, it will do all you need..." or something like that.

first, i was lucky enough to wheel with some of the rising sun folks last year, and several had HAMS's.. if memory serves, you run on freqs 146.XXX on the trail? dunno...

anyway, im a LT. with the local fire department up here, and i have kenwood, yeasu, and Bendix King radios at my disposal, but of the three, the BK is the only one that is field programmable, the others are programmed to department standards...

what im looking for is a 'dual purpose' radio to hard mount in my rig. I need to get fireband, duplex frequencies for repeated, simplex for car to car..

Gilpin, County of

154.86000 KNCJ828 BM 100.0 PL (Gilpin Blue) FM
154.02500 WPLU575 RM (Gilpin Green) FM Multi-Tac
153.84500 KSO936 BM 100.0 PL GLPN FD/EMS Gilpin County Fire & Ambulance Dispatch (Gilpin Red) FM Multi-Dispatch

High Country Fire Department

154.14500 R 100.0 PL FM Fire Dispatch

however, i'd also like to get the Ham Freq's the various 4x4 groups work off of.

i'm looking for a single radio that i can preset and scan my emergency freq's for 'on duty' work... and that will also handle field programmable frequency's for 4x4/hobbiest's.

other things im told i want are:
- high/low power operation 50w/5w?
- CB bands?
- remote mount 'box' so only the head/display are dash mounted
- no controls in the mic so any 'standard' microphone can replace a damaged mike?

is there such a beast? if so, what is the make/model of one that will do what i want so im not carrying my CB, Handheld fire radio, and ham...

(before you say it, no, i don't have a ham operators license yet.. i'm planning on getting it as soon as possible....)

Unfortunately, I think the simple answer is No.

Your work frequencies are outside the 2M and 70CM band. 144-148 Mhz and 420-450 Mhz. These are the only frequencies you'll be able to use with a Ham technicians license and also what most of the mobile amatuer radios are limited to.

Caveat to say simple answer is no legal way to get around 3 radios if you need to transmit on all three services.

The group uses 146.460 simplex on trail runs.

Most any 2 meter radio will allow you to monitor in the 153/154 frequency range. The Yaesu 2800 has a receive range between 137-174 MHz.

i guess im confused .. still... although youd think "no" is easy enough to understand.

on ebay, there is a hand-held

1 Motorola MT2000 full keypad VHF 5 watt 10 zones 160 CH 136-178 MHZ

which would appear to transmit and receive 136-178 and claims to be a 'fire / police / ham ' radio. would this not work for what i want, sans CB..? I see several mobile mount units with higher power as well... many EX fire radios as fire departments convert to the 800-band radios..I just havent found a mobile unit field programmable..

Just because it can cover the frequency range does not make it legal. It's not a question of technical capability, but one of laws and policies. The right MT2000 and programming software can allow you to program in both ham and public service frequencies.

The stickler is that once you use it to transmit on ham that makes it illegal according to the FCC to use for any other service.

Also the MT2000 can't do 15KHz channel spacing AFAIK, which means it won't line up with the 2m VHF amateur band plan (e.g. 15K0F3). The MT2000 I believe is wide band FM only.

now im getting somewhere...

right now, (apparently), i can legally use my fire radio, either department issued or privately owned, in the course of my duties...oversimplified, i know but..

I can, and several members have, fire radios in thier POV's and i always carry my hand held radio, in case I need to respond..

if we assume i am / get my amateur radio license, are you saying that i cannot use the same piece of hardware for hobby and emergency use, but I can use two different radios legally in the same vehicle?

if this is the case, the fed needs to be smacked with the logic stick.....

While it really doesn't solve your problem, you can program a mobile amature radio to listen to the emergency freqs and then when something comes up that you need to respond to, you pull out and turn on a handheld.

Another issue, at least with a 50w mobile rig, is that you need two antennas, one for 144-148Mhz, and one for 153-154Mhz. On a low power HT, transmitting with the SWR mismatch would not be as detrimental.

As others have stated, to stay compliant with current FCC rules, you need two radios, type accepted for the intended use. There are many instances of 2M and 70CM ham radios being modified (The majors use the same internals for commercial/ham/public safety radios, so the mods are way too easy) and used to jam or otherwise interfere with public safety repeaters. I used to help the S.O. hunt them down. Just like gun laws, the FCC's rules only stop the law-abiding citizens who would follow the rules anyway, and do nothing to prevent the bad guys from misusing the tools.
