radio transceiver

I have been looking into survival and bug out gear on the internet and on you tube. What radio transceiver would you choose if a disaster or terrorist attack hit and you had to leave your home. I have been looking at the YAESU VX-7R & YAESU VX-8R what do you think of these radio's?

I have a VX-7R and it's great. Now that the VX-8R's out I probably would have gone with it based on features alone, however it seems to me you'd be more interested in the ruggedness of the VX-7R. It's a pretty solid built radio and can take abuse. They're both submersible and maybe the VX-8r can take abuse too; time will tell. The VX-8r has built in APRS support which can be great in an emergency situation where an EOC needs to see where everyone assisting is located at any given time. The optional GPS puck maximizes this of course. VX8r has bluetooth capabilities which can be handy as a wireless hands free system.

Keep in mind that these radios only transmit on 6m/2m/1.25m/70cm which are all generally local communication bands. If you're without a repeater or a satellite in view, you're not going to be able to communicate a heck of a lot of distance, especially with the supplied antenna. They both can receive shortwave although the ferrite rod antenna built into the VX8 is better suited for this. Personally, I'd like to have an HF radio and easily deployed antenna for an emergency. The little HT's are great for local emergency coordination but if things really hit the fan and you want a way to talk to the outside world, only an HF radio is going to cut it. A little FT-857 and a trolling motor battery and a roll of wire for an antenna would do wonders. An FT-817 is even more portable with an internal battery but limited to 5W. Something to think about.

Just showing my new Kenwood TH-F6A HT radio and demonstrating SSB and CW receive on 20 meters. This radio offers FM receive and transmit ...

I know that there is a book out, but I'd rather not go out and get it. If you all could, please tell me an easy way to build a radio transceiver- with materials and instructions.

plenty of instructions on the net!
For an AM set:
Reciever:
Antena with a very small capactior linked into a coil thats in parralele with a variable capacitor in series with a diode in parallel with ear plugs/amp/speaker.

Transmitter:
audio transformer into oscillator with a voltage supply into the output (antena).

Here is a website which describes these methods in great detail!

Enjoy it I know i loved that site when I started making radio's a few years back.

During political debates. You have seen the photos.
I think its the only way he would have managed a live televised debate. We have given him such a pass all through his two pResidencies.
FREAK: and now that we know a little more about George W - how popular is he today ?

You really gotta wonder if RePukes ever get tired of having to come up with endless excuses for Bush's endless list of disappointments, embarrassments and failures.

looking for simple and easy to use
Yes hand held

I personnaly like the Small Yaesu units. They are easy to use, waterproof (protected anyway) and have alot of audio for the size.

The Icom Units are also good units. Both companies have years of handheld production behind them and both have strong service centers.

(Sorry if it seems like a dumb question)...

I know aviation enthusiasts can use them to tune into airband frequencies but can you get ones where you can transmit a message via a handheld radio to a particular frequency?

Any recommendations where to buy cheap but efficent airband receivers/tranceivers?

Any information or advice is much appreciated.

Many thanks.

a receiver receives, a transceiver receives AND transmits.

airband transmitters (as are all transmitters) are regulated by the FCC. Airband transmitters would be especially sensitive as would fire, police, etc. Therefore, unless you are an air traffic controller operating from an official duty station, don't even think about it.
