wrote: well,... I guess i can add this question. is your wired phone attached to Cable? i understand that in alot of metro areas, the cable companies are now offering phone service across their lines. I don't know anything about the equipment but this could be a issue if the power goes out. Cable has a small box for translation with very limited backup battery. Once power goes to either the head end or the VOIP translation box.. you are screwed. There is also sutff like Vonage and the other voice over IP "appliances" you attach to your broadband connection for phone service, however VONAGE over something like DirecWay satellite would be a good emergency backup, as long as you could provide your own power. With vonage, you can pick the 911 PSAP, so you can even dial 911, and it ends up in the right jurisdiction. |

If I had to contact either cops or amublance i would have no way of doing that except of standing on the street and waiting for the cop car to pass by. That's why i asked the question of how one would keep a line of communications if the regular ones were out. snip Interesting. My phone, an old type, worked just fine. Some places I did not get an answer and some numbers, when first tried, I got a recording that all lines were tied up. Only lost power for about 5 hours., took a nap for most of that.

Cellular phones didn't work either. This is also mostly not true. Most cell systems were overloaded, but the carrier signals were largely still operating, due to back up batteries and generators. In other words, they weren't working. -- Joe Bramblett, KD5NRH |

With that you can either get in touch with your relatives directly, provided they have ham radio as well, or you can call some person in an area without blackout and tell them to call police/ambulance etc if that's what you need. Not knowing much myself about scanners/shortwaves/hams myself I want to ask you guys with more experience if the below piece of equipment is what I need. As far as I understand this is an handheld ham radio which also functions as a scanner and can also receive on a shortwave band. So it will allow me to communicate with people far away even in urban setting, it is portable and it will also allow me to monitor news as well as police/firefighters etc. Am I right? Yaesu VX-2R http://www.universal-radio.com/catalog/ht/0176.html the price is kind of steep but for all-in-one product I would be willing to pay it. Find the local ham club and discuss what you are looking for with one of them. In my area, you could listen to emergency services. However, non of them have gone to trunked systems. During catastrophic events such as hurricanes and ice storms, we provide interagency communications where there is no common frequency. For example, we have ridden with the National Guard picking up people stranded in homes when those people called 911. Since normal protocol for us it to establish a presence at the Emergency Communications Center at the request of the County Emergency Manager, a ham could call for help if needed. Several repeaters in the area have battery/generator backup, so loss of power is not an immediate matter for concern. I've seen us without power to the repeaters for up to two weeks and we kept them going. So, if you were in my area I'd say to go for it. However, ham radio is not government sponsored. All of those repeaters are installed, maintained, and supported by the hams who use them. Therefore, conditions vary a lot from area to area. For example, my home town has one repeater and it's at a hams home, maintained by him, and has no back up power supply. There are three hams that live in the area. He and his wife are two of them. The radio that you are looking at is way underpowered for simplex communications between two units. I'd look at a used two meter mobile and keep my scanner. You can pick up an older used two meter mobile for less than $100. I have a lot of advice and opinions, but I'd rather defer to the local hams in your area who know the specifics of their systems. Give them a call. Most all hams love to help someone get into the hobby. |

Electricity including phones were out. In our area (Detroit and suburbs), the phones are powered by the phone companies and were not out. Apparently the phone companies do have some type of backup power. However, if all a person had was a cordless phone, then it did not do any good since those have to be plugged in to external power to operate. The non-cordless variety doesn't need that. After swapping my phone over, I was able to call my daughter to check to see if she was OK since she was stuck at a friend's house until gasoline pumps were operational. Cell phone coverage here was erratic either because of overload or because the cell sites lost power too without sufficient backup power. My best means of tracking the situation was ham radio. I got a lot more detail on exactly where and when power came became available and where and when it would be possible to get gas for the car and generator. Commercial radio broadcasting did not give very good or timely information on these aspects of the situation. They would state that "power is back on in parts of xxx" with no further detail. Via ham radio, I was able to find out what parts were back up so I could assess whether to go try to find gasoline or wait a bit longer. Dee D. Flint, N8UZE |

Flint, N8UZE If this is the case then why doesn't one of the local amateur radio operators make themselves available to the local news anchor, much like cellular users report traffic problems on a normal day, and that way the generalpublic could be better informed.

Most all the hand-held amateur radio equipment, is almost useless without
the aid of a repeater station. I don't know how many repeaters are backed up by emergency power supplies. I would hope most of them, but if they're not, don't plan on reaching anyone more than a couple miles away. H.F. equipment, on the other hand, is usually at least 50~100 watts, and has the ability to reach extremely long distances, without the need of a repeater. When you think about it, standard C.B. radio equipment should do well, providing there is someone available on the other end. Bill Crocker "mad amoeba" wrote in message . net...

It depends greatly on where you live (or are) in relation to where you want to talk to. I live in a very ham dense area and can make dozens of contacts on simplex. I don't know how many repeaters are backed up by emergency power supplies. I would hope most of them, but if they're not, don't plan on reaching anyone more than a couple miles away. Glancing through the repeater directory, I'd guess about a third of them. How do you define, "a couple of miles"? My Icom T2H (a 7 Watt hand held) can make it from my house to the repeater 18 miles away. If I can hit that repeater then I can talk to anyone between it and me on simplex, and that is with the rubber duck antenna. Using a home made twin-lead J-Pole antenna I talked on the repeater from downtown Chicago which is a 36 miles trip. On 2 Meters, get your antenna high and you can really reach out. Height is Might. H.F. equipment, on the other hand, is usually at least 50~100 watts, and has the ability to reach extremely long distances, without the need of a repeater. Wattage doesn't mean a whole lot with HF because it isn't the power that enables the longer distances. My 2 Meter rigs at home are 50 Watts. Actually, most HF rigs are 5 to 10 Watts and an external amp will be used to increase power. Depending on conditions, you can talk all 50 states with 10 Watts on HF. When you think about it, standard C.B. radio equipment should do well, providing there is someone available on the other end. IF you are in an area with CB users and IF they are helpful and not just kids wanting to screw around. Also, CB, being limited to 4 Watts is typicallty very short range. If you are in an area with a lot of CB users that are 'adult' and use it as a tool then it may be the proper answer. Same for FRS and GMRS. Where I am, CB is worthless due to the people that use it. If you can't top someone elses signal then you aren't going to talk. Bill Crocker KB9WFK "You are behaving like a troll, disguising your attacks as reasonable discussion." 'Alan Connor' |

(all of it snipped) Sorry, if this has been mentioned (I can't read all 60 replies) but .. While the radio in question can recieve shortwave, it can't transmit there (and even if you could modify it to .. it would still only be FM and low powered) Without "repeaters" a hand held ham radio is very, very limited in range. There are other possibilites .. such as the Yaesu 817, but you'd need a higher class of ham licence and (realistically) a bigger, better antenna (and a lot of luck) for HF (High Frequency .. aka 'shortwave') communications.
