In order to set up a packet radio station in a LEGAL sense, you will
have to obtain your Amateur Radio licence in order to access the
resources and networks of the Amateur Radio community. For info on
Amateur Radio in the UK, check out:

... or you might wish to do some research into available licence-free
radio bands in your country and establish your own communications links
with friends. In North America, there are many areas of the radio
spectrum that are available for low-power licence-free operation. Some
examples of licence-free bands that either exist now or existed in the
past in North America are: 27 MHz for CB Radio, low-power walkie-talkies
and remote controlled model aircraft and toys, 49 MHz for cordless
telephones, walkie-talkies, baby monitors and remote controlled toys,
900 MHz for various wireless consumer devices, and the new 460 MHz
Family Radio band - there may be more, and data transmissions might or
might not be permitted on any of them (I haven't looked into it). You
will have to research similar available frequencies in the UK and
determine if data transmissions are permitted.
> how much will this equiptment cost (i'm on a very
> tight budget) who/what exactly will i be communicating with (SE
> London area, UK)
Cost will be determined by the network you choose to establish, of
course, and so will the stations you can communicate with. A minimalist
approach to wireless communications would be a low-power consumer
walkie-talkie with a BayCom or TigerTronics modem connected between your
PC's serial port and the radio's speaker and microphone connections.
You would be able to operate 300bps or 1200bps with such a setup,
depending on the audio frequency response of the radio. You would
be able to communicate with whoever else you can convince to join
you. I suspect that you wouldn't have any problem communicating with
your friend a block away, and packet radio is designed to relay data
from one station to another in order to extend communications range
beyond the coverage area of each individual station. You would not be
able to communicate on your own across a town or city with a low-power
system such as this.
Should you choose to become an Amateur Radio operator, the above
mentioned methoods along with a used 145 MHz FM radio would enable you
to access the Amateur Radio packet radio resources in your area.
> will I have to errect a massive Antenna in my Garden?
For Amateur Radio operation at VHF and above, the antenna need only be
a few feet in length. For low-power licence-free operation on
appropriate non-Amateur frequencies, the antenna might need to remain
attached to the radio, or have other limitations in order to remain
legal. The efficiency of your radio system is affected by the
performance of the antenna. Maximizing the efficiency of the antenna
within permitted parameters will maximize the range of your station.
> Can you get TCP/IP packets to the internet via packet (just for
> smtp,nmtp etc. , not HTTP)
Yes, with the appropriate communications software and a packet link of
resonable speed, you can link to the Internet and do whatever you want
(on a licence-free system). Amateur Radio packet has legal restrictions
with respect to content that you will have to familiarize yourself with.

> - if so, is this legal/
In some countries Amateur Radio links to the Internet are permitted,
in other countries they are not. With respect to a licence-free system,
you will have to contact the appropriate authorities in your country,
tell them what you have in mind, and ask them. You will also have to
abide by the terms-of-service of your telephone company and ISP. Call a
UK radio inspector on the phone about Amateur Radio or low-power
licence-free digital communications - he's a civil servant, that's what
he's there for.
> does it cost money?
Communications equipment, telephone lines, Internet connections and
radio licences generally cost money.

Packet radio networks exist on CB radio. It is your responsibility to
determine if such operation is legal in the UK, and if you wish to
participate if it is not. For information on CB packet, check out:
http://www.dxzone.com/catalog/CB_Radio/Packet_and_Digital/
You should also go to http://www.altavista.com and use
+"packet" +"radio" +"cb"
for your search parameters.

You're welcome. Good luck with your experiments, and I hope that one
day you will choose to join us on the Amateur Radio packet networks.

Hi,
This request for K7IQI, a BBS SYSOP in OR. <k7iqi@aol.com>
The SYSOPs in OR are looking for a packet BBS in Utah for
receipt/further relay of NTS message-traffic. < @ NTSUT >
The BBS would need a HF Pactor/Clover port.
Any info appreciated. To me <for relay> or to K7IQI.
