What good would ANY of that do for an FRS radio? If you want more channels, go buy a commercial UHF radio and program all the channels you want into it. If you want more power, it won't help. UHF is line of sight only (unlike CB) so more power is almost no help at all. Antenna info, you could get a GMRS license (which covers your whole family) and use radios with external antennas to your heart's content legally! Here's a website with a gob of FRS info I read: http://www.popularwireless.com/gmrs.html |

What do you mean by line of sight??? Do you mean that if i try to talk to somone on the other side of a big wearhouse it wont work? thats compleatly untrue. To me all radio signals are line of sight, but with enough wattage then problem solved. (within reality) Taz |

It would be nice if you could rig up external antennas for frs radios. That distance would go from 1-2mis to 5-10mis. |

Well, Has anyone thought of taking an inexpensive FRS radio and removing the builtin antenna and installing, say, maybe a connector to which you could then attach an antenna with a BNC connector. This way, you could run coax from the now removable antenna to an external antenna. I don't know how difficult it would be to retro-fit an FRS radio with a new, removable flexible antenna, but it might be worth a try for someone who has some skill in re-working plastic and rubber and such. By the way, I thought I saw an advertisement, maybe from Radio Shack, for an FRS radio that came with an external antenna that could be placed on the roof of your car. Or have I been dreaming again?

Taz, "What do you mean by line of sight??? Do you mean that if i try to talk to somone on the other side of a big wearhouse it wont work? thats compleatly untrue" Don't be ridiculous! First of all, I'm no liar. Second, Line of sight means radio line of sight. Yes, it will work from one side of a warehouse to another. It will not likely work from one side of town to another if the radios are at street level. Get one radio up in a building and it works again. Sorry... "To me all radio signals are line of sight, but with enough wattage then problem solved. (within reality)" Well, reality is that UHF is not going to go further with more power. If the antennas can't 'see' each other, 1/2 watt or 10,000 watts will not make it work. UHF does not behave the same as the lowband propagation does from your CB radio. Why is this always such a struggle? I give up on you guys. I am seriously tired of the uphill battle to explain things to the CBers out there. It's not that you don't understand, you don't WANT to understand and you blame me for things which I cannot control. It's not fair or entertaining anymore. I'm out. |

The Radio Shack unit has the transmitter in the base of the antenna and all controls on the mic. FCC rules and regulations for FRS states no external antennas can be used.This was kind of neat, last May at the Rochester NY hamfest someone had a simplex repeater set up on the FRS band.This is a large hamfest but the repeater wasn't really needed, my girlfriend watched our table while I looked around and we had no trouble using FRS unit to unit. |

Hey hamcber, I just think there is a personality clash here. U say that us cbers dont want to learn? well i think for all cbers when I say that we all want to learn. And do you know somthing hamcber, I think alot of the people would be well,,,, like lost without you here. you play a big part in this forum and I think you need to continue to be a big part of it. you said: Why is this always such a struggle? I give up on you guys. I am seriously tired of the uphill battle to explain things to the CBers out there. Why is it an uphill battle? Is it just because you are so much more intelegent that it gets frustrating that you need to explain things 10 times? Well, one thing is that you kind of jumped in on the forum and automaticly kind of thought you knew more than us. Well if that is the way you feel then you should realize that you are going to have to go through and uphill battle because not all people are the same and are going to understand. everyone has the right to their 2 cents. If they are wrong or you just dont agree then bummer, its been said before and i will say it again, diferent folks different strokes... Taz 73's 411 phoenix arizona and im out..... |

I think the best mod would be to install a bnc connector so that you can use an alternate antenna. No need to do any mods if you can give yourself 10 to 20 DB of gain with a beam. |

Walkie-Talkie, that's really cool. I would like to play with that a little in the future. My Ft 847 will work in the GMRS/FRS range, as well as MURS. Another area I've thought might be fun would be the el cheapo 49 mhz HT's--With my Yaesu as a base, I bet I could get pretty good range out to a mobile running a 49mhz HT with an external antenna on the vehicle. |

There are a couple of new FRS base radios out there as well as a GMRS base and they are very reasonable.I know that Walmart has the Audiovox FRS base on sale for less than 40 dollars and it has the 38 security codes and loads of other features. It is pretty easy to make a ground plane antenna that could be hooked up by adding a BNC connector.I already have all the GMRS freqencies in my modified Yaesu VX-1R dual band (ham) handi-talkie and using a tiny mag mount VHF/UHF antenna can send and receive on FRS,GMRS and MURS frequencies.The VX-1R has a SMA antenna connector but I got an adapter for a BNC connector.The VX-1R does 1/2 watt with the rechargable battery and 1 watt when using a power supply or lighter adapter.I believe that a FRS radio could be made to do the same basic thing if you can modify the hole where you cut the fixed antenna off so a BNC connector can be attached. I am about ready to try it on one of my spare units.If it works,I'll post the results. |

Higher frequency = higher path loss(yes, more loss in the atmosphere at the same distance) Gradually, as you get into the UHF range, you get NO groundwave propagation, only direct and reflected radiation. You will only get over the horizon at a 4/3 ratio. Yes, with a 2 inch antenna on a handheld, you will get more line of site range with UHF than HF. This is because of the effeciency of the small antenna at high frequencies vs. low frequencies. CB frequencies will propagate beyond the horizon via groundwaves manty times farther, relatively. It sorta gets into this quandry, antenna size vs. path loss. |

In responce to the thing about watts not having much affect on the vhf and uhf band.....I know I've responded to this thing before but I just wanted to say that isn't 2 meter ham VHF?If not it's mighty darned close to it.Well what I'm gettin at is legally you can run up to 1500 watts with those radios (legally).You might not ever need to use all that juice but every now and then you need to "pump up" the juice.Sure AM might be more responcive to power but FM needs it too,just not as much. |

In my opinion Line of sight comes into play when one radio can recognize that another radio is transmitting, therefor line of sight is radio line of sight, would or would not adding more power increase line of sight for the radio? it seems to me that if another radio has more transmit power, then another radio of the same be it am fm uhf hf vhf or whatever would hear it better or should I say recognize it better seeing as how line of sight has increased, or maybe we should figure out how to boost the recieve on these little bugers so they can "see better!" |

FRS (Family Radio Service) were designed to keep in touch with the kids at the mall, with your buddies when you go hunting or what ever else you like to use them for but the key here is the word family. I hope that is what they are used for we don’t need a bunch of wacko-s to start increasing the power and overpowering someone who is trying to keep in touch there kids at a park. Do any of you recall before cell phones when you tried to use the CB to call for the help that you needed and all you got was people making noise over your little 4-Watt radio. Now everyone uses cell phone on the most part today so they can get help when they need it but like I said a family on an outing can find these little radios invaluable. So lets not be the ones to pump it up and ruin it for the people that really need it. |

Could some1 possibly enlighten me some more? From what I gather you can only talk to the radio(s) that were sold in the same pack. What about other radios in the immediate proximity to you, do you pick up their transmissions (given ur all on the same freq)? 1 or 2 miles? That's no fun, I can spit further than that. We need to use our powers to figure out a way to freq-mod them to hit repeaters-NOW it's getting interesting. |

I'm liking this topic. The thing I don't understand is why external antennas are against FCC rules.All it does is improve the range of them,it's not like it pumps up the power or anything so I don't understand the problem there. By the way 181,they have a FRS out now made by Motorola (I think) that has a roger beep.That would be neat though.I plan to purchase a couple of Motorola FRS radios in the near future.I do like the looks of the Midland FRS's though and the Cobra's.But going into the radios I think it would be fairly easy to rig up and extrnal antenna to them.On the inside there's like a little copper ring that connects to the stock antenna.By removing the stock antenna and soldering a wire to it ( the copper ring) you can make a small wire antenna (to the correct measurements) then stick it up in the air as high as you can get it.Maybe the FCC wanted to enforce the 2in antenna cuz they wanted the radios to be a short range radio but with enough range to be useful.Wonder what it would take to get a GMRS lisence.Anybody know?? |

Hello all, Just to let all know, on Ebay you can pick up an Audiovox GMRS/FRS base unit, that has external OR battery power, headphone-mic inputs AND most importantly....a DETATCHABLE BNC antenna!!!! These are only about $40 with the BUY IT NOW option. I got one and it's a really solid unit. Go check them out. You could run one as a base, the other in the car with a cigarette lighter adapter & external antenna for little money. Does anyone know a good design for a base antenna to build? And, is 50 ohm coax the correct cable to use? Hope this helps everyone, as I have never seen these base units in stores, only on Ebay. Cheers Andrew 739 |

Ncrebel, Keep in mind that when you get your GMRS license, you are allowed 50 watts, not 5. However, on UHF, you can't tell the difference between 5 and 50 watts. I own a UHF repeater that has 14 watts coming out of the duplexer. Covers 60 miles and more very solid. Using a Decibel DB408 antenna and a 3000 foot high (above average terrain) mountian does the trick. It's a lot different than 27 Mhz. CB! |

You know, it's ridiculous to think of modding an FRS radio. These radios were not made for extra power or xtended freq. coverage. Most FRS radios are so small that it would take a microscope to look into them. The only mod that does sound good is redoing the antenna and somehow being able to use an external antenna. As for more power and xtended freq. coverage, do what others have stated, buy GMRS or commerical UHF. |

Isn't the GMRS license $70? This cost encourages illegal use of the inexpensive so-called frs/gmrs radios that are filling the shelves at the "W" stores and the "K" stores. Also, notice that these radio have NO repeater frequencies in them, so as not to REALLY grab some attention by licensed GMRS users. I sort of have a problem with the license cost. $25, maybe. A test over general regulations? Okay with me. Oh well. The FCC will continue selling our RF and microwave bandwidth and not really providing any noticeable services. All the folks they gave backrubs to in the wireless industry have sold out (they say, well this PCS market outlook is like this...), taken their 7 and 8 figure bonuses, left the industries in the tech sector in a bad way so they cause a recession so some of us can't afford a GMRS license. The FCC must be planning to use the revenues from these fees and frequency alottments to save our Lucents, ATT&Ts, Iridiums, etc. so the engineers and technicians will get their jobs back. Off my soapbox. Other than that, I would love to use GMRS. I have a big family and the use of a repeater by all of us would be real nice. Add the security of extended local communications at the mall, in the vehicle, and so on and it would be hard to resist. |

Let me know how it goes! The midland G11 for the car, question? How do you connect the outside antenna for car? Does it have a detatchable antenna on it? Also does it require an antenna that has a low SWR for the base situation, ie an antenna made to the correct frequency , not just a scanner antenna that is only for recieving? A nice little 6 element quad loop antenna would kick butt eh!! Cheers Andrew 739 |

Sixtiesmania, the G-11 Midland has an SMA connector, so the rubber ducky threads off, and then the coax from the magmount antenna threads in. For the base antenna, Discone antennas can transmit well on most Vhf/Uhf frequencies with a good SWR, just basically no gain. But Height is what will really matter here, not so much gain. But you're right, one can put together a nice directional antenna with very little space needed. Me and a friend built a couple of 3 element quads for 2 meters that worked excellent. I'm hoping to be able to work the mobiles in town (5-8 miles, generally) |

I cut the little coil antenna off my Cobra GMRS/FRS and soldered a piece of 14-Guage Magnet Wire to the copper ring. I melted a hole in the flexible antenna cover and ran the rest of the wire out the top. I trimmed the antenna till I got the highest reading on a Field-Strength meter (about 5 7/8"). It performs better than the stock antenna on the other Cobra handheld (TX & RX). Just an idea for you guys and very simple to do.... |

I took apart the radio shack unit,it is going to be easy to put the transmitter/rf section into a shielded box with a uhf connector on the box and connect it to the klv ula50-1 amp.I have it one the bench right now and with about 475 milliwatts into the amp the output is almost 19 watts.Not too bad that will get out very well.I have the unit connected to a diamond antenna right now and I am hearing several stations on channel 8{467.5625}.Tommorow I will install unit in the box with permanent connector and 12 volt d.c. plug.Tthis klv amp also has a pre-amp in it too which will improve recive quite a bit.This week I will try some range tests to see how well it will "get" out.Should get about 15-20 mile radius if not alot more.My antenna is up about 26 feet in the air,so 18 watts with that antenna gain should be good.By the way I bought 2 of these from radio shack here and when I bought 2 the manager gave them to me for 19.95 !!!!! He said they are discontinued, he was doing inventory,and did not want them around anymore.The next project is to increase the power in the antenna unit to put out more so that I can use this in a mobile.This will take alot more work,but should be able to put a board inside to put out 2-3 watts.That would make this into quite a neat little unit.Wwill update soon. |

I found a toshiba rf module at work today that should put out about 3 watts.The base of the antenna is heavy metal so it should provide a good heat sink.3 watts with outside mobile antenna should work well.i my also do away with the antenna/rf assembly like I did on the base and just put rf assembly into shielded box and use that in a mobile with a good uhf antenna with some gain,3watts-high gain antenna= good range !!!!

Handheld radios generally will talk "radio-to-radio", "line-of-sight" up to 2 miles. Once you start putting obstacles in between the radios you will shorten your range. Even the body fluid of the person wearing the radio on their hip will absorb some of the range. Higher wattage radios will have a slight increase in range and a significant increase in clarity of transmission on the outer fringes of your range. |

What's the status on the developments put forth in this thread? I found these efforts to be pretty interesting. Ryan, how is your repeater working? |
