How Do I Use Radio As A Internet Connection
 

How Do I Use Radio As A Internet Connection, i am wanting to know how i can
use a mobile ham radio and hook it up to a laptop to be able to connect to
the internet so i can use irc chat dont need fast connection speed. would
like to be able to chat on IRC while camping/fishing ware no cell service is
avaiable.

You can't. If you were a licensed ham you'd know that.

Your best bet is to use 802.11 to do this for local
use. In hjam radio you just need to set up a box with
the approarate software and connection. You can use
Linux to do this with and a packet controller. You will
need a clear frequency and a minimum speed of 9600 for
best results.

That is why i am asking if it can be done if it cannot be done then i wont
do it and stay away from ham radio. don't want to waste my money getting a
license or the time to study if it cannot be done.

Don't waste your time or money. The Ham Radio hobby is for people who have a
genuine interest in radio. It is not a communications carrier or a back door
to getting freebee services. Generally, the "freebee" services ham radio
provide require a substantial investment in both personal time and money in
order to exist or to be utilized. If you don't have a particular interest in
radio, you will find that ham radio is ultimately unsatisfying. You have to
learn a bunch of stuff, work cooperatively with other people, follow and
respect not only the FCC rules but ham radio's "gentlemen's agreements" as
well. Many people will expect you to show an interest in community service.

You have made it plain that your interest in ham radio only goes as far as
what kind of "freebee" it might give you... That's not really a good enough
reason to go through the effort. You'd be better off without ham radio, and
ham radio would be better off without you.

I'd say your best bet is to go with plan "B"; something that does not
involve ham radio.

It's not a question of whether it CAN be done. In the technical
sense, of course it can. The question is whether what you want to do is
applicable to the real purposes of the amateur radio service.

I will add that getting wireless access to the Internet is not why
the service exists. You would know this if you had taken the time to do
some basic research with Part 97 of the FCC regs, or visited ARRL.org
and read 'The Amateur's Code.'

If you don't like the thought of helping to serve the real
purposes of amateur radio (helping with disaster and other emergency
communications, teaching a ham radio class, developing the skills and
acquiring the tools necessary to tinker with radio and related
electronic hardware, etc.), then you would be well advised to steer
clear of the amateur service.

In short: If all you really want is wireless Internet access, pop
down to your local CompUSA or whoever, and pick up the hardware to do
it. Anyone who wants to can buy it, no license required.

There is a new radio by ICOM called D-Star that suppost to let you do this.
I'm not sure of the FCC rules but ICOM's website is a good place to start. I
understand it cost about $1400.00 and works at 1.2G so it's costly for what
yo are looking for.

Very good point about commercial content in web pages.
To the original question: Does it have to be Internet chat or can't you
simply use the digital communication modes that already abound? That would
be simpler, provide more options and probably much more reliable.
For the sake of conversation, how much would the option to view a webpage
in text-only filter commercial content (i.e. pop ups, banners, etc.)? The
topic is fairly common among folks interested in ham radio. Or, is the only
true solution to filter, edit and make available certain html pages from a
stand alone server via a club station's ham radio?

Charles,
Of course the idea of filtering anything off the web was just
brainstorming and I'd never put my callsign behind anything like it either.
Thanks for not lighting a match at the utterance of the E-word on a ham NG.
I'm just rambling outside the box.
For the Group: Is it plausible to pass data through a repeater above or
below voice just like the subaudible tones?

Hi,

Well, getting a ham license isn't exactly a waste of time, but it does
carry some responsibilities. Unfortunately for us, one of them is
abiding by communications law.

Currently, governments like to be able to trace directly where
communications on their system originate. It has to do with law
enforcement mainly. Hams in the US have been able to do email via the
internet for a while, and it is regarded here in Australia as
"allowable" for licensed hams providing they don't have direct access to
the 'net.

I think such services, if allowed, would be swamped fairly quickly with
illegal operators anyhow (remember how CB got going?). And someone still
has to pay for the fixed station bandwidth, both on air and cable. If it
ever comes to pass, be assured that the government will charge heavily
for the right to monopolise a static frequency.

Sure it is. It's just another Internet application. That's part of

Don't let these folks discourage you. If you don't want to put up
with a bunch of naysaying hams, look into going the licenseless route
with MURS. MURS allows digital communications, up to 2W transmitter
power, and best of all, gain antennas (so you can construct
communications links having fairly decent comm range).

For more information on MURS:
http://groups.yahoo.com/group/MURS-OPEN

Again, I respect you interest in radios, and your application, and
depending on your application you may be able to get by without
directly messing with ham radio... although, if you catch the radio
bug, you may find you want to get a ham license after all.

Again, don't let these folks discourage you.

Stuff that's faster, easier, and more accurate to type/read rather than it

If somebody comes up with a subaudible tone data system, even at a low data

The question about sending data using subaudible tones reminded me of a
quick 'n dirty soundcard digital setup I found for use over voice repeaters.
You can't talk while its working, but it does allow you to go back 'n forth
between voice and data. There are probably times when that would be useful.

I was playing around with FlexNet's Flex32 version of Q15x25 mode, called
"newqpsk". This mode is intended for HF, and uses fifteen 88.3 baud PSK
streams to give you an effective 2500 baud. I decided to try it out on VHF,
then decided to try bumping the TXDELAY up around 500-600 MS and see if it
would work over the local voice repeater, connecting to another VHF newqpsk
station in town on that frequency.

It worked very well! I was at home, and my friend had a laptop in his truck
across town. We were able to do all the regular digital stuff. Newqpsk is a
lot like packet to use, but of course sounds very different. You can send
binary files with it, because it has error correction like packet.

The easiest way to check out newqpsk in Flex32 is to see the "Soundcard
Packet" tutorial at USPN, that describes the setup of Flex32 for 1200 baud
afsk packet. On the part where you choose afsk for the soundmodem from a
dropdown menu, just go down to the bottom of the list and choose newqpsk
instead. That's the main difference between setting Flex32 up for newqpsk
instead of packet. When reading the tutorial, don't miss the part at the
last where it recommends the PAXON terminal program. You'll be glad you did,
PAXON is really nice.

This is not bad; A 2500 baud digital setup that can be used anywhere there
is a voice repeater. The high TXDELAY introduces some slowup, but overall
it's fairly snappy. - Good enough to get some lengthy or involved text sent
across, or perhaps a small binary file like a JPEG. Since it's a soundcard
mode, it's very portable and the price is right too. (free)

Note: The MixW Q15x25 dll package sets you up with an interleave of 16. To
make the Flex32 newqpsk version compatible on the air with MixW stations,
bump its interleave up to 16 as well.

between voice and data. There are probably times when that would be useful.

I was playing around with FlexNet's Flex32 version of Q15x25 mode, called
"newqpsk". This mode is intended for HF, and uses fifteen 88.3 baud PSK
streams to give you an effective 2500 baud. I decided to try it out on VHF,
then decided to try bumping the TXDELAY up around 500-600 MS and see if it
would work over the local voice repeater, connecting to another VHF newqpsk
station in town on that frequency.

It worked very well! I was at home, and my friend had a laptop in his truck
across town. We were able to do all the regular digital stuff. Newqpsk is a
lot like packet to use, but of course sounds very different. You can send
binary files with it, because it has error correction like packet.

The easiest way to check out newqpsk in Flex32 is to see the "Soundcard
Packet" tutorial at USPN, that describes the setup of Flex32 for 1200 baud
afsk packet. On the part where you choose afsk for the soundmodem from a
dropdown menu, just go down to the bottom of the list and choose newqpsk
instead. That's the main difference between setting Flex32 up for newqpsk
instead of packet. When reading the tutorial, don't miss the part at the
last where it recommends the PAXON terminal program. You'll be glad you did,
PAXON is really nice.

This is not bad; A 2500 baud digital setup that can be used anywhere there
is a voice repeater. The high TXDELAY introduces some slowup, but overall
it's fairly snappy. - Good enough to get some lengthy or involved text sent
across, or perhaps a small binary file like a JPEG. Since it's a soundcard
mode, it's very portable and the price is right too. (free)

Note: The MixW Q15x25 dll package sets you up with an interleave of 16. To
make the Flex32 newqpsk version compatible on the air with MixW stations,
bump its interleave up to 16 as well.

If somebody comes up with a subaudible tone data system, even at a low data

Motorola land mobile radios in the pre-trunking days
had an option for something they trademarked as
"Digital Private Line". It was basically 100 baud
data, IIRC, sent as base-band data with the voice
(in other words, 100baud data stream directly
mixed with audio). The radios obviously needed
good DC-response. The sequence sent was something
like a 23-bit pattern was FEC-expanded from a 16-bit
or somesuch digital code. I think there was also
the equivalent of traditional "reverse-burst", a
sequence sent to mute the receiver when the transmitter
unkeyed, to avoid a burst of unsquelched noise.

100 baud data has a base-band bandwidth well-inside
traditional PL if well-filtered or sent use a
raised-cosine/DDS arrangement. Alternating
1s and 0s produce a 200Hz sine wave. Existing
PL filters in receivers and repeaters would filter
DPL out as if it was regular PL. In this sense,
it was quite compatible with existing PL.

Certainly DPL provides a wealth of interesting
background; you can find examples of the hardware
in service manuals for MCX100s and other 1980s
vintage Motorola land-mobile. I'm sure other
OEMs had similar technology.

They key item to successfully sending low-baud
data over an FM transmitter is low distortion,
which means a transmitter with near-DC response;
this is achieved by modulating both the VCO and
reference oscillator in a PLL system. Most ham
radios I've looked at are unsuitable since they
only modulate the VCO and the PLL will suppress
modulation below 50Hz or so.

The other key lesson here is adopting a heavy
FEC approach since you're not in a packet mode,
you're bussing data along with voice. Send short
chunks of data which are robustly FEC-encoded.
It may limit what you can actually send during a
normal voice contact.

How Do I Use Radio As A Internet Connection, i am wanting to know how i can
use a mobile ham radio and hook it up to a laptop to be able to connect to
the internet so i can use irc chat dont need fast connection speed. would
like to be able to chat on IRC while camping/fishing ware no cell service
is
avaiable.

Don't let these folks discourage you. If you don't want to put up
with a bunch of naysaying hams, look into going the licenseless route
with MURS. MURS allows digital communications, up to 2W transmitter
power, and best of all, gain antennas (so you can construct
communications links having fairly decent comm range).

And where would one purchase such equipment?
Let me guess!

For more information on MURS:
http://groups.yahoo.com/group/MURS-OPEN

Again, I respect you interest in radios, and your application, and
depending on your application you may be able to get by without
directly messing with ham radio... although, if you catch the radio
bug, you may find you want to get a ham license after all.

Again, don't let these folks discourage you.

You just did exactly what you complained about Stew.
You discouraged the use of ham radio.
Please take your MURS trolls to the appropriate newsgroup.
Seems like every time someone suggests using ham radio
you pop right up again and advertise the MURS solution.

Why is that?
