If the internet is turned off........be ready.....video

[Ponce]

I already have about five of them (short wave radio) and with another coming in.

ponce,

why did you prefer 1102 over 1103?

[Ponce]

I don't know what you are talking about but this is the one that I am waithing for......it will not be out in the market till the middle of Jan.

GRUNDIG S450DLX PORT DIG AM/FM/SW 99.99 99.99

Ponce, the radio in the video that you posted is very familiar to me
it is china-made Kaito/Dengen KA-1102.
there is a newer model of the same radio called called KA-1103

the KA-1103 is considered the most sensitive SSB shortwave receiver below 100$
yet it has most horrible built and such ergonomics that drive people crazy.

note that S450DLX does not have SSB (single side band) (!)

[chad]

thanks for posting this thread. i've been meaning to buy one, this has motivated me. guess i'll buy that cheap ka-1103....

[Ponce]

Chad?........what do you mean by "single side band"........thaks.

[G2Rad]

Ponce, without SSB you will not be able to listen to ham operators and informal groops


by the way, in February of 2007 FCC deleted the Morse Code requirement from the Amateur Radio Service rules

amature SSB sets sometimes can beam 100 -150 watts of peak envelope power, all of which goes into conveying information

that translates into tens of thousands of miles for the HF

moreover, I've heard rumors of HF-SSB modems. which could mean private independent email service via the radio

[G2Rad]

Chad?........what do you mean by "single side band"........thaks.


Ponce,

I don't know how technical you are

google SSB or single side band.

the point is, without SSB you'll not hear military or ham operators

you will only be able to hear commercial/news stations

KA-1102 that your video advertises has SSB capabilities

[Ponce]

OK, thanks.........I took my Morse Code training at Ft Gordon while in the service and I still can't recieve worth a damn, I was better with a .22 with a hush puppy...... two of my SW are able to get MC and sometimes I record what I hear and then play it till I get the message.........but sending I am faster than Speedy Gonzales hahahahahahahaha.....MOS was 052PL6685

[G2Rad]

If you do FFT (Furrier transformation) on a signal, THEN
in the frequency domain the Spectrum will consist of two side bands on each side of the carrier peak

( most energy is in the carrier peak )

two side bands - are like mirror images of each other

only one side band of the spectrum has to be transmitted over radio waves to transfer 100% of the information without any loss.

the rest of the spectrum - ( another side band and the carrier peak) can be reconstructed by the receiver.

such receivers are called SSB receivers.

efficiency of SSB is about 16 times better than the standard AM/FM transmitter

SSB can cover long distances with much less power than unmodulated AM/FM

me too was trained in Morse when in army in the 80-s
me too forgot it all ;D

SSB is not "a gismo for Morse freeks" ;D you don't need to know morse :)
it is mode (modulation) of the radio that allows listening to chat of ham radio operators, marine transmitions, sometimes military, some times all kinds of weird stuff

[G2Rad]

ponce,

here is radio every cuban must have ;D

G2, So what is the best bang for a buck on this subject? I don't know anything about these which is why I have not picked anything up. When I was reading on it I had more questions than the words I was reading. I don't need a crash course just something that will do the job, I can learn as I go from that point.

TIA

I would suggest reading Amazon's good and especially bad reviews (http://www.amazon.com/Kaito-KA1103-Portable-radio/product-reviews/B0006OCEFY/ref=sr_1_1_cm_cr_acr_txt?ie=UTF8&showViewpoints=1) on KA-1103 and Grundig G400A (http://www.amazon.com/Grundig-G4000A-AM-Shortwave-Radio/product-reviews/B000807GJK/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1)

ka-1103 has best shortwave reception in its class, but also has myriad of stupid buttons arranged in most annoying way and falls apart quicly like most Chinese stuff do. Grundig is no German either anymore. There are no good western-made radio. There are no all-around great radio on the market. IMHO. do your own diligence :oo-->

[Ponce]

I really missed my good old Radio Shack 25 years digital SW with a metal case.......someone stole from my home about 20 years ago........THAT WAS A SW RADIO.

Hey G2RAD?.........I don't even know what that is......all that we had back in 1960 was the VRCQ-60, ANG-3 and the damn 30 lbs radio with a five miles range and batteries that weighted 10 lbs each........why hell, one of my walkie talkie has a range of 36 miles and goes in my pocket.

[G2Rad]

the same chinese Dengen that makes Kaito KA-1103 now makes (designs) electronics for most of Grundig radios

Grundig G400A may be the last one on the market that was designed in Germany if I am not mistaken


western world lost radio technology


Japanese Sony may be the last man standing, but the rumors are that they are leaving portable radio market

kind of sad

[chad]

i just ordered that ka-1103 for $75 off amazon. for $75, i'll chance it.

[Ponce]

Good for you, something is better than nothing..........hummmmmm somehow that doesn't sound right, but you know what I mean hahahahahahah.

[Cebu_4_2]

G2 the Kaito KA1103 looks like the way to go as far as radio goes, what about one that is a transmitter also??

I'm really lost now lol.

[General of Darkness]

I'm with Cebu, it's cool to be listening when TSHTF, but I also want to be able to transmitte. "This is General of Darkness, please provide your location because I'm coming to stab the lot of you in the dicks, General out".

[osoab]

I would love to give some info on this, but I am rusty.

I only have my tech license and only have a couple of 2m radios.

You would need to look into something like packet radio (http://en.wikipedia.org/wiki/Packet_radio).

One of the first meetings I went at our local HAM club had a session on sending data packets over radio waves.
I think 4800 bps was tops, this might be too high also.

You also need to remember that you would need to power a computer as well as the radio itself.

For distance you would need a HF rig. 10m, 20m, or 60m meter range.

Cebu, SSB HF transceivers are way out of my ball park of expertise

sorry.

you can look them up on the ebay, if you want

but, ..... you will have to deal with FCC licenses, hundreds of $ to invest, antenas
you'll have to become a geek too IMHO ;D

as far as emergency two-way communication, if disaster hapens the cell phones will not work,
cell phones use an equivalent of digital trunking technique, that is when you share a table of channels over bandwidth with all the others.
when a disaster happens and many people get on the phone at once, all the channels got taken and the system overloads.
basicaly cell phones won't work

I personaly have this (http://www.amazon.com/Motorola-MR350-35-Mile-22-Channel-Two-Way/dp/B001UE6MJ8/ref=cm_cr_pr_product_top) as my family back up. (we live in the same town )
it got pretty cool 1.5 watts, 35 miles mountain top to mountain top. I love these little radios.

Do your own diligence, for example read reviews (http://www.amazon.com/Motorola-MR350-35-Mile-22-Channel-Two-Way/product-reviews/B001UE6MJ8/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1)


my biggest investment in radio waves is a police scanner.
useful thing to have if you want to know what cops are up to in your neighborhood
a lot of pretty spooky stuff is happening right next door.
even in such quiet town as mine.
I can peek up police in the city as far away as 25 miles with my scaner.
I can peek up railways, shopping malls, schools, hospitals, airport shuttles, etc

WTSHTF who the hell will care about a license........the question is "do I need a license to buy a transciver?"

No you don't just to operate it but if SHTF I think a license will be the last of your worries.
