FRS walkie talkies
I've got a Micro talk. Runs on four AAA cells. Do you use nicads, or just
put in new batteries every morning? My Motorolas run on three AA cells, I think they last a bit longer. Christopher A. Young Learn more about Jesus www.lds.org ..

Me and JH do a lot of telecom and data wiring and the radios come in handy when you're 300' away from your co-conspirator trying to sort out or find cables. We've been trying to find a young guy maybe 50 years old or so to help us pull wire up in ceilings where it's difficult for us to climb around. ^_^ TDD |

I have a pair of nice little 22 channel Cobra Micro Talk GMRS/FRS radios that work very well. I also have some Cobras. They run for nearly a week on 'listen', and with intermittant talking (say 10 minutes a day) keep up on regular alkalines for about three days. LLoyd |

Are those the ones with four AAA cells?
The one time I was doing wire pulling and other work at a volunteer job, set of AAA made it through one shift, and only part way through the next day. Of course, I was on third floor of VERY tall floors, and my batteries were in the van. Now, I always carry the second set with me. Christopher A. Young Learn more about Jesus www.lds.org .. "Lloyd E.

Young Learn more about Jesus www.lds.org The AA cells have much higher capacity than the AAA cells. See the Duracell spec sheets he http://www.duracell.com/en-US/Global...ets&cc=Primary You'll also get much longer battery life from a radio that uses a physical click-on/off switch than one that uses a touch-on/off switch. The touch switch typically draws a small but continuous crrent from the batteries I like the Uniden EcoTrek FRS420 and FRS440 radios that have a click-on/off switch on the volume control, use three AA cells, and have a clip that hangs well from a belt loop. After a number of years, on of the FRS420's has a problem with low audio output, but I've had them so long I no longer remember when I bought them. Along the way, I've used Cobra and Midland FRS radios that were smalller and lighter, but used AAA cells so required more frequent battery changes. One of them came with rechargeable batteries, but only their rechargeable batteries could be used with the stad charger - their batteries were large enough to trip the internal charging switch, but normal size rechargeables didn't because they are the same size as standard batteries. |

I was just reading article on batteries, Dad tore the article out of a
magazine for me. For digital cameras, NiMH last a lot longer than alkalines. That might be the case with FRS walkies, I'm not sure. On my old job when my boss kept turning off the FRS, I finally gave up and used cell phone for all my cellar to attic comms. Christopher A. Young Learn more about Jesus www.lds.org ..

The littlest marine VHF are Cobras. The batteries have been upgraded to NiMH, and they run a lot longer. They are mainly used by "crew" to talk to the "ship". That way I can monitor the on-board VHF (loud enough for me to hear easily. If they go overboard it's not big loss. They were cheap, true. But they've rune for 4 years now. Except the one that jumped ship one day. Haven't heard from it in a while now... MY personal VHF is also a cheapie , rebranded by West Marine. I have it because it's waterproof (10 10 feet) and floats. So I take it with me when I'm sailing on other boats. The rest are FRS, which we use now and then around the house, or between cars when traveling. I consider them to be disposable so no big deal if something happens to them. All except the Coleman. It's pretty cool, so I keep it for me. |

Thanks for the real world report. I'd been using Motorola FR-50, and had
good results with them. They don't have the squelch codes, so once in a while I get some cross talk from some other units. The one time they failed me, I was on a roof, and leaning into a HVAC unit to check things. My man on the ground tried to reach me. He was maybe 100 yards or more away. The squelch opened, but I didn't get any voice. Figured it was some other unit at a distance. I finally got back to the roof edge, and he radioed to ask why I didn't reply. Oops. I should have leaned out of the unit and radioed "was that you?" Christopher A. Young Learn more about Jesus www.lds.org .. "Bob La Londe" wrote in message ...

Keep in mind that NiCd and NiMH cells have a lower voltage than alkaline
cells even when they are fully charged, so you start out at a disadvantage. They will likely need to be recharged far more often than alkalines would need to be replaced -- and there is a limit to the number of times they can be recharged.

Oddly enough, NiMH last longer than alkalines in digital cameras. Charging
flash is a high demand application. Transmitting on FRS is also a high current draw. I'm not sure, but NiMH might last longer in walkie talkies. In any case, a night in the charge stand is cheaper than a set of replacement alkalines. Rechargables self discharge, so a walkie kept in the back pack for occasional camping trips needs alkalines, cause NiMH would be dead by then. Christopher A.

Not unless you were line of sight with no steel in between, nothing to cause multipath (As in TV ghosting) and at least a full wavelength from the nearest large piece of steel. the signal quality & levels are affected by all those factors. On top of that the antennas aren't very good on a handheld, since there isn't a good counterpoise. |

Well, walkie laying on top of the RTU can't be much worse than being in a
heavy metal box. And, the quarter wave for FRS is about six inches, the TX antennas are limited to four inches, which is totally not resonant. With all these problems, I'm amazed how well FRS works.

Years ago, I read the FCC web site on FRS. Back then, they were non
commercial, only. A lot of stores use FRS at the store. I went back and read the web page, the non commercial bit had disappeared. I'd like to see base stations sold. For example, farm house, to contact the guys in the farm field. Midland has a "base station" with hand held microphone. I'd make one of those on four D cells, so it would last a while. They used three AA cells. What advantage is that? Antenna not removable, either. Christopher A. Young Learn more about Jesus www.lds.org .. "Michael A. Terrell" wrote in message m...

Several cheap frs units, some broke. When I first started using them, most people did not use cell phones, at least the younger persons could not afford them. They still can't afford them. One base unit has all the bells and whistles. My radio shack is built well but simple, toggle switch to set channel, act as frs intercom. I measured my midlands, gmrs having at least 2 watts. Greg |

Greg The farthest I transmitted was at least 8 miles on hilltops using my best frs, icom and radio hack mobile unit. Easy to talk to planes. The longest frs contact reported in nuts and volts, was something like 130 miles or more on some kind of atmospheric deal. I know at one time on lake Erie I connected through a Canadian cell site using AT&T system, 50 miles away. Never got billed, back in mid 90's. I think I may have got billed another time, that's how I found where I connected through. The reception was real weak on near shore stations, but 10 miles into the water, reception was great with stronger towers visible. Why am I talking about cell phones. Greg |

Great, where it works, and absolutely useless in fringe areas that old analog equipment is still usable. The earliest FM two way radio systems used 30 KHz channel width, and it's gone down hill since then. Narrower channels, lower power & lower towers. I installed a low band 250W base for a guy about 30 years ago. He could talk to Middletown, Ohio from his semi on hilltops in the middle of Kentucky as he drove loads of cardboard boxes down I-75. A county near here spent well north of a million dollars to replace their analog system with digital. They had four remote towers & voting hardware to give 100% coverage for the county. Motorola convinced them that wasn't needed, and they ended up with less that 35% reliable coverage. That they could fix for a few more million. |

FRS walkie talkies / cell roaming
Back when there was Frontier Tel, and Genesee Tel, in the Rochester NY area.
I had a mobile cell phone in the van. I was near edge of Lake Ontario, and the pager went off. I called the answering people, on roam. And then the customer. Turns out my cell was working towers in Toronto, Canada, and it was costing me two bucks a minute for roam. Christopher A. Young Learn more about Jesus www.lds.org .. "gregz" wrote in message ...

They had big M come in and install all new gear across the state all of it P25 crap. The coverage area went from something like 85% in the worst spots to less than 60% now in the best locations. There were a couple videos out that showed them testing the system and two people were less than a mile apart and could see each other but the radios wouldn't work. Then there are the guys in NYFD who can stand on opposite sides of a brick wall and cannot talk. Just what you want for crews who will be risking it all entering a building on fire and they can't talk to the crew outside!!! -- Steve W. |
