uk.radio.amateur Frequently Asked Questions
===========================================
This will be a periodic posting to uk.radio.amateur and rec.radio.info of
UK-specific questions and answers on amateur radio. It is not intended to
be exhaustive, but to point you towards sources of further information
where necessary. I would welcome any constructive views on this FAQ to
ukfaq@topsy.demon.co.uk .
For ease of distribution, the edition of this FAQ posted to Usenet has been
cut into 2 parts.
The latest version of this FAQ is available for anonymous FTP from
ftp.demon.co.uk
Part 2 of 2
-----------
26. What is packet radio ?
Packet radio is a data communications mode that uses a modified form of
the X25 signalling protocol. Simply put, two packet radio stations that
are within direct range of each-other can establish an error free data
connection, normally at 1200 bits per second (baud). Packet radio
stations may also act as automatic repeaters ('digipeaters') and can
relay other stations' signals. Using packet radio, many bulletin boards
or mailboxes exist to handle messages for those active on packet radio
in their locality, these messages can include 'bulletins' that are open
to all and are often distributed across every packet radio bulletin
board in the UK, or further afield. Most packet radio is operated in
the 2m and 70cm bands.
For a fuller description of packet radio see the digital-faq posted in
rec.radio.amateur.digital.misc and available by anonymous FTP from:
rtfm.mit.edu//pub/usenet/news.answers/radio
ftp.amdahl.com//pub/radio/amateur
27. What equipment do I need for packet ?
Life used to be simple, all you needed for packet was a VHF or UHF
transceiver (depending on where you lived), a terminal or computer
running a terminal-emulation program and a Terminal Node Controller unit
(TNC). The TNC contains a microcomputer and controls all communication
between the terminal and the remote TNC being connected to. Now cards
containing a TNC (or two) are available for the PC & compatibles and
other computers. Additionally, there is a system that uses a simple
modem, or a TNC acting as a simple modem, with the host computer
controlling the communications. Finally there are the TNC's that do not
require a local terminal ..... ask an expert.
28. What are the limitations of packet-radio in the UK ?
At first packet was illegal in the UK, or maybe it wasn't. The licence
did not make this clear. Now it is an established communication mode
and recognised by the RA. This means that they have made a few special
arrangements if you want to run packet. Firstly you must send a morse
ident to give your full station callsign at least every 30 minutes. And
you should send a packet ident every 15 minutes. Next, you may only
pass on mail addressed to a specific amateur station, unless you hold a
Notice of Variation to your callsign (designated by a GB7... callsign)
- in which case you don't need to read this section :-) .
29. I want to leave my packet-radio station unattended.
Providing the commencement of unattended packet-radio operation is
logged in the station log then unattended operation may be in the
following bands or sub-bands: 50-51MHz, 70.3125MHz, 70.3250MHz,
70.4875MHz, 144-146MHz, 432.6-432.7MHz, 433.6-433.7MHz,1299-1300MHz
(excluding Northern Ireland), 2310-2450MHz, 3400-3475MHz, 5650-5680MHz,
5755-5765MHz, 5820-5850MHz, 10000-10250MHz, 10270-10300MHz,
10400-10500MHz 24000-24050MHz and all bands including and above
47000MHz. The position regarding the 70cm band is changing and the
latest position should be sought in all cases where the licencee is not
certain.
30. Can I use packet to exchange messages with Internet users?
The only messages that may be carried by the packet network are those
sent by licenced amateurs. There are no official gateways from packet
to Internet in the UK due to the problem of controlling which messages
are from licenced amateurs on the Internet side. This is under review
by the RA. There are, however, gateways in the US and elsewhere that
will forward internet email from licenced amateurs onto the packet bbs
system. It is necessary to register your callsign and email address
before using these gateways.
31. What facilities are available in the UK by packet ?
Most user-level packet is at 1200baud with some linking still at
1200baud but moving to 9600baud, or beyond. At this data rate, little
more than BBS access is possible although the DX Cluster network for
notification of DX is very strong in some areas. TCP/IP (and its
related servers) are established in some areas but there is by no means
a national TCP/IP network.
31. How do I obtain a .ampr.org IP address ?
There are local co-ordinators assigned to each RSGB region, and in some
cases they delegate address allocation further to local co-ordinators.
Your nearest BBS sysop will probably know who runs TCP/IP locally - if he
doesn't there's a fair chance that activity is so low that you won't find
any other operators anyway !
If you have any difficulty, the UK co-ordinator is Paul Taylor, G1PLT
(ptaylor@email.meto.govt.uk) . He should be able to put you in touch with
your regional co-ordinator.
32. UK Band Plans
Use of the allocated bands in the UK is voluntary to a large extent.

using any mode you like, but see the booklet BR68 from the
Radiocommunications Agency. The voluntary band plans are as follows:

33. Can anyone use my radio ?
Anyone who holds a current UK-issued licence, or a valid CEPT licence,
or a valid reciprocal licence, may use your station for frequencies
for which they are licenced under their own callsign. In addition to
those listed, a UK Novice licencee, holder of a pass slip from the
Radio Amateur's Examination or an Amateur Radio Certificate (who does
not hold a licence), or a licenced amateur from any other country, may
operate under the station's callsign on frequencies that you are
licenced to use providing you are in attendance.
When operating a club station, a message may be transmitted from any
person providing it is a greetings message of less that two minutes
duration and is sent and received only within: UK, USA, Canada, Falkland
Islands or Pitcairn Island.
When using a digital mode, anyone may type the message for transmission.
34. I have a dual-band rig, can I use it as a repeater ?
Some VHF/UHF rigs are capable of acting as a cross-band repeater,
operated by carrier-sense. Unless these are licenced as a repeater
(with a GB3.. callsign) or being operating by an emergency
communications group under a current 'talk-though' permit then they
may not be used as a repeater.
35. My neighbour complains he can hear my voice on his television.
This is a case of Radio Frequency Interference and the correct term is
'Electromagnetic Compatibility' or EMC. Where the reasons behind the
problem is not clear (and they seldom are), consult one of the many
guides to EMC problem-solving. One good source is the ARRL Handbook
(published annually by the American Radio Relay League). Another is the
Radio Amateurs' Guide to EMC by R. Page-Jones G3JWI (published by the
RSGB). Abbreviated advice from the latter volume is to be found in the
RSGB Callbook & Information Directory. There is a network of EMC
Co-ordinators to give local advice in extreme cases. Details from the
RSGB. For those suffering interference, a useful guide is a booklet
called How to Improve Television and Radio Reception, published by the
Radiocommunications Agency a few years ago. It is now out of print, but
many copies are in circulation.
36. I want to take my radio to sea / use it in an aircraft.
Maritime Mobile (/MM) operation has been a part of the UK licence for
several years now, previously it was a separate licence. On a vessel
that is not yours you must obtain the written permission of the
vessel's master before installing or using a transceiver (this includes
cross-channel ferries). The master may insist that you observe radio
silence at times and this must be done. In international waters, only
those bands that are permitted for the ITU region being visited may be
used. In non-UK territorial waters, be aware that amateur activity in
harbours may not be permitted. If in doubt, seek advice from that
country's authorities before travelling.
Aviation mobile in the UK is not permitted and the licence is quite
specific about this. If you are carrying a transceiver by air make
certain you can switch it on to satisfy the airport security then
switch it off and leave it off.
37. The Radio Society of Great Britain (RSGB).
The RSGB is the national society representing amateurs in the UK to our
licencing body (The Radiocommunications Agency). Many people have many
views on the RSGB and it has often been criticised, but it's the only
body of it's kind that we have :-)
The RSGB's address is: RSGB
Lambda House
Potters Bar
Herts
EN6 3JE
U.K.
The main telephone number is 0707 659015 (+44 707 659015)
The fax number is 0707 645105 (+44 707 645105)
They do not have a reliable (or easy) e-mail connection to HQ (they use
BT Gold :-( ) but several RSGB Committee members are active on Internet
and/or packet-radio and their details will be added to this FAQ as and
when they are known.
The RSGB is the main publisher of amateur radio books in the UK, they
also publish a monthly magazine for members called 'Radio
Communication', more commonly known as 'RadCom'. The editorial team for
RadCom can be contacted on 0707 659015, fax 0707 649503.
The RSGB broadcasts a weekly amateur radio news summary every Sunday
under the callsign GB2RS. This is broadcast nationally on 3.640, 3.650,
3.660, 7.0475MHz. Local broadcasts are on 51.530, 144.250, 145.525MHz.
Times vary, see the Callbook and Information Directory for full details.
The text is copied to packet-radio (NEWS@GBR) and to Usenet by Ted Batts
G8LWY.
38. The Radiocommunications Agency (RA).
The RA is the licencing body in the UK. Any queries about licencing
that cannot be otherwise dealt with should be directed to the RA. Their
address is: Radiocommunications Agency
Room 712
Waterloo Bridge House
Waterloo Bridge Road
London
SE1 8UA
U.K.
Their telephone number for enquiries is 071 215 2150 (+44 71 215 2150).
The RA publishes a number of advice leaflets and information sheets and
these are generally free. These can be obtained by contacting the RA's
Information and Library Service at Room 605 in Waterloo Bridge House.
The telephone number is 071 215 2072 (+44 71 215 2072), fax 071 928
4309 (+44 71 928 4309).
For queries over licence renewals, contact Subscription Services Ltd
(SSL): Radio Licencing Centre
Subscription Services Ltd
PO Box 885
Bristol
BS99 5LG.
Their telephone enquiry line is open Monday to Saturday 0830 to 2200hrs
on 0272 258333. There have been many reported problems with licence
renewals recently and this should be borne in mind.
39. Local Clubs.
Probably the best way to meet local radio amateurs is at the local club
meetings. These are too numerous to list here but once again a full
list is found in the Callbook and Information Directory, from the RSGB.
Many clubs also feature in the "What's On/Meetings" section of local
newspapers and the various amateur radio magazines.
40. Specialist Clubs.
For those with an interest in a specialist branch of amateur radio,
then these clubs and societies tend to be very useful:

Of course, there are many more clubs than those listed above but these
are the clubs primarily dealing with branches of amateur radio.
41. Commercial Magazines.
The RSGB's RadCom is not available in newsagents as it is a members'
journal. Those that you will find in the newsagents are:
Practical Wireless
Short Wave Magazine
Ham Radio Today
All are published monthly.
42. Internet news groups
For UK-specific news, try uk.radio.amateur - this FAQ is intended for
that newsgroup.
The main Usenet groups for radio-related topics are listed below. The
policy group in particular has a heavy US bias.

43. Other FAQs
As stated elsewhere, this FAQ is not exhaustive. You may like to check
out the FAQ's on amateur radio that are posted regularly in
rec.radio.info and rec.radio.amateur.misc, obviously having regard for
the non-UK slant to many topics. The main ham-radio FAQ (US in origin)
and ham-digital-faq are available by anonymous FTP from:
rtfm.mit.edu//pub/usenet/news.answers/radio
ftp.amdahl.com//pub/radio/amateur
44. Is the UK callbook available on disc/CD-ROM ?
The information available on UK amateurs is much more restrictive than
that on US amateurs, due to differing legislation and attitudes to
public information. However, some of the information in the Callbook
published by the RSGB is available. This does not appear to include
callbook entries where postcode (zip-code) information only is given.
Ian Hampson G1DFT (ian@ainsdale.demon.co.uk) offered in uk.radio.amateur:
I've seen a couple of requests for the UK callbook on disc. Well, it's
available on 2 HDD PC floppies from me if anyone wants it. Send me two
blank disks and an SAE [sufficient IRC's outside the UK - Editor] and
I'll do you a copy. Mark your envelope - 'callbook'. The callsign files
come with an excellent PD search routine.
And John Heaton, in rec.radio.amateur.misc said:
For the last few weeks or so a copy of the UK Radio Amateurs Callbook
1994 has been passed around the UK amateur community. What I have done
is to put the callbook up on our HTTP server :
http://www.mcc.ac.uk/htbin/callbook
This database holds just over 49000 UK amateurs
This information may also be available on one of the US-originated
CD-ROMs but I have no details.
45. Caveat.
A lot of information for this FAQ has been taken from the licencing
booklet BR68 and the RA's information sheets. The licencing information
was probably correct at the time I copied it, but do not take anything
as being authoritative. The licence is constantly under review and this
FAQ could easily be out of date. If in doubt, check!
46. Credits.
