DRAFT/DRAFT!
Report from the Committee C 5. VHF/UHF/SHF Von Hellmuth
Fischer, DF7VX,
131102 PA0EZ, Chairman of the Committes C5 opens 10 November 2002
the first meeting on Monday. To the conception present VHF/microwaves
Manager(30) from countries (22) went it to the first item on the
agenda, which itself essentially with still different points of
action of the Lillehammer - conference 1999 concerned.
Particularly to emphasize is, which was not possible it to date
within the IARU region 1, an expert person closes here, who can
fill out this important function as satellite co-ordinator for
the IARU region 1. On Monday 10 November 2002 still possible
installation of a satellite of specialist from the DARC these
very important interests with large specialized knowledge have
represented could, could not regrettably not be realized.
The complete agenda covers 43 single points in the appropriate
order to be specified here. The requests to those by me one
reports here as appendix (zip file) to this report to find.
SEE PLANT 4
DOC C 5,3, of the DARC became presented in the 70 cm volume plan
under the category. Usage, uses. taken up. Thus the frequency is
439,9875 MHz for the Procsac applications a component 70 cm of
the volume plan.
DOC C 5,4 the footnote i. in 145 MHz the volume plan is changed
accordingly, so that the so-called kanalisierte enterprise of
digital applications in the frequency range 144,800 to 144,990
MHz now possesses a correct status.
DOC C 5,5 under this point were represented very in detail the
problems of the different frequency assignments of today's and
future view. The necessity for the operational readiness level of
very expert radio amateurs pointed itself to that national and
internationally existing frequenzmanagement committees as
essential.
DOC C 5,6 the use of the frequency range 144.630. 144,640 MHz as
expenditure frequency range for linear transponders, as well as
144.660. 144,690 MHz as input frequency range for linear
transponders with majority one agreed. Thus results now also for
the Federal Republic of Germany the possibility of the use of
linear transponders in 145 MHz the volume.
DOC C5.7 by the use of the frequency 144,800 MHz for the APRS
system, with a range of +/- 6 kHz is it necessarily a new so-called
critical frequency/dividing line to be specified. This is now the
frequency 144. 79400 MHz.
DOC C 5,8 the use of 1.6 MHz SHIFTS in 435 MHz the volume plan is
subject within the IARU to region 1 unites characteristics. The
clear clarification of the Repeater SHIFT situation in Belgium
this becomes in 435 MHz the volume plan by the indicator ON.
marked. As additive mentioned the idea also in 435 MHz the volume
the use genuine 12.5 kHz of a frequency allocation to ethablieren
does not meet agreement.

DOC C 5,11 this request concerns itself with at present an
assignment not yet possible with us to the amateur radio service
within 70 MHz the range. It was specified that in the frequency
range 70.030 MHz to 70.050 MHz beacons can be operated.

DOC C 5. 14 in this of the RSGB brought in paper is represented
the current, as well as the future microwave assignments to the
amateur radio service. This results in the suggestion: if always
possible/must each kind of the Amteurfunknutzung in these
frequency ranges is to take place in primary assignments of this
frequency spectrum. This suggestion meets general agreement.
DOC C 5,15 for this is it necessarily the text existing as draft
for VHF of manager manual to prepare (see plant 5)
DOC C 5,16 also this request becomes in the summary. Principals
OF volume plan engineer discussed. Plant 1/(ad hoc Working Group,
GÂSR, OE1MCU, DF7VX, LA8KV, PA2DWH)
DOC C 5,17 the request of the SRAL to introduce here the use of
the classes of emission APRS on the frequency 144,825 MHz was
back pulled by the SRAL representative.
DOC C 5,18 the request was discussed in detail, however there are
no concrete suggestions like the frequency range 50.0000. 50,020
MHz to be used is.
DOC C 5,19 this request of the SRAL was withdrawn after a short
discussion over the for and against.
DOC C 5,20 this request meets the ungeteilte agreement of all
present ones.
DOC C 5,21 this information paper will become briefly discussed
and all members of the Committes C 5 requested this information
about this alternative EME frequency range their members the
knowledge to bring.
DOC C 5,22 QSL maps for beacons, a good idea not only in VHF of
manager manual to be published is. To support the federations
asked by an appropriate publication into their amateur radio
magazines this suggestion.
To DOC C 5,23 definition of a procedure for the new classes of
emission FSK 441 (WSJT) see separate representation.
Plant 3 DOC C 5,24 this request of the SRAL was treated
particularly in detail, since it concerns here a not simply
solvable problem. Nevertheless it was agreed upon to affect the
members into the amateur radio federations going by that for the
classes of emission telegrafie as also as possible the frequency
range proven for this classes of emission is used. Practice
observed at present to use here also frequencies in the so-called
SSB range for the classes of emission telegrafie it could to the
fact lead that the explicitly proven range for this classes of
emission remains more and more unused. This cannot be in the
sense of the radio amateurs.
Here DOC C 5,25 definition for a complete Meteorscatter (ms)
connection (QSO) is formed a working group, in order to revise
those to date no longer very current publications to this topic
in VHF of manager manual.
DOC C 5,26 in the request of the Norwegian amateur radio
federation is suggested the frequency 144,800 MHz for the classes
of emission APRS. This request we by the majority affirmatively.
The additive to the Nichtbetreiben of so-called NICHT, likewise
contained in this request, LINEAR transponders in the frequency
range 144.000. 144. 794 MHz spareless one paints.

Working Group, GÂSR, OE1MCU, DF7VX, LA8KV, PA2DWH)
DOC C5.30 this request is brought in by the Danish amateur radio
federation and is to minimize now the situation in the Nordi
countries with a very strong use of the ISM assignment in 435 MHz
the volume somewhat. The nordischen countries, here Denmark
Norway, Sweden and Finland have very substantial problem with
input the frequency range of their automatic stations, there
itself these almost exclusively in the so-called ISM frequency
range (433.050. 434,790 MHz find. To the minimization of this not
insignificant problem there is the possibility some changes of
volume plan to accomplish according to the statements of these
countries concerned only within the IARU region 1 defaults. Of
the EDR suggested possibilities of substantial changes in the
existing volume plan for the frequency range 432,000 MHz to 435,000
MHz are discussed again very in detail. Turns out, which does not
want to probably accept a majority of the present federations of
these changes in the spoken form. After this contentwise and
extraordinarily material discussion by the Chairman a tuning with
the following result is led here (9:7) against the acceptance of
this request. However agreement was going by obtained to speak
again about this topic around possibly possible changes this
situation into that nordic countries something defused to think.
On Wednesday, 13,11,02 the topic was discussed again very in
detail and the following compromise settlement was found. The
Telegrafband in 435 MHz the volume plan is reduced by 50 kHz. The
new range begins now with 432,000 MHz and ends with 432,100 MHz.
A second change concerns to date with 432.800. 433,000 MHz proven
beacon volume. Here there was a clear majority for a transfer and
a reduction of this range votierte. The new beacon range is into
the frequency segment 432.400. 432,490 MHz (similar to 145 MHz
beacons assignment) to be shifted. In the FRG are of it approx..
20 beacons concerned, which can accomplish such a frequency
change however according to my estimate. For the further
relaxation of the situation one agreed upon, the assignments to
the enterprise of linear transponders in 435 MHz the volume (432.

relatively rarely, this is to be problem-free too accomplished
also here from my view, particularly since it does not bring any
effects on the used frequencies and the enterprise of these
plants with itself. However it knows to Kollisionsproblemem to
borders FRG/Denmark to come, which appears solvable however by a
coordination of frequencies for these different applications.
Other assignments in the FRG, as they are manifested in 435 MHz
the volume plan e.g. by footnotes, do not have influence on these
measures. This modified volume plan suggestion such a thing with

Apendix:
SUBJECT Machine Generated Modulation (MGM) – ALLOCATIONS IN THE
50, 145, 435, 1296 & 2320MHz BANDS
SOCIETY
Committee C5
BACKGROUND:
Committee C5 agreed on the principal of using bandwidth as the
criteria for the allocation of Machine Generate Modulation (MGM)
modes in the VHF, UHF and microwave band plans.
The Committee also agreed that an exclusive TELEGRAPHY sub-band
is still required.
It was explained that there are different requirements for
maximum bandwidth depending on the type of transmission. The
working group therefore notes the need for two segments. One
segment with maximum bandwidth up to 500 Hz (for modes like PSK31)
and one segment up to 2700Hz (for modes like FSK441).
Based on bandwidth criteria one segment should be placed at the
current border between TELEGRAPHY and SSB. The second could be
placed anywhere in the SSB segment.
A good solution will be the ”high end” of the SSB sub-band.
· +/- 15kHz (30kHz wide) segments from the present borders
between SSB and CW
· The lower 15kHz (in the TELEGRAPHY portion) will be for MGM
with a maximum bandwidth of 500Hz. This is primarily for EME
operation.
· The upper 15kHz (in the SSB portion) will be used for MGM with
a maximum bandwidth of 2700Hz.
· A 40kHz wide sub-band (in the SSB portion) immediately below
the BEACON sub-band will be used for TELEGRAPHY, SSB and MGM
modes with maximum bandwidth of 2700 Hz.
· Activity centres will be allocated within these MGM segments.

Working Subgroup Report and Recommendations in the mm Bands.
The Working Subgroup on mm bandplanning has reviewed the current
situation on the bands above 71GHz where there will be very
significant changes to both the Amateur and Amateur Satellite
Service allocations within the next 1 to 2 years.
A. Considering that
1. There is need for harmonization of segments in all the mm
bands
2. Both Amateur Services should be advised to use the Amateur
Primary segments, where these are available, in preference to the
Amateur Secondary segments as soon as possible, in any event
before the end of the changeover period
3. The new allocations are already implemented in at least two
IARU Region 1 countries and will be implemented in more
countries, possibly by mid to late 2003
4. In all cases, including 24 and 47GHz, the Amateur Primary
segments are allocated to the Amateur and Amateur Satellite
services on an equal basis
5. High performance equipment and techniques now available are
equally suitable for terrestrial, satellite and eme use, and the
advent of a 24GHz satellite downlink has stimulated narrowband
activity in the Amateur Primary segment of the band. Therefore it
is desirable that such activities be brought together in order to
stimulate further activity.
6. In the future, there should be no compatibility problems
between the two Amateur Services
7. It is almost always easier to get approval for unattended
devices, for example beacons, in the Amateur Primary.
B. The following proposals are made in the light of current
information and are confirmed by Committee C5
1. The same principles should apply to the 24 and 47GHz bands in
addition to the bands above 71GHz
2. Detail within the Amateur Primary segments should be agreed
and implemented by 1 January, 2004
3. Narrowband modes should be within the following bands, and in
line with current practices
24.00 to 24.05GHz as now, Primary
47.00 to 47.20GHz as now, Primary
77.50 to 78.00GHz NEW, Primary
122.25 to 123.0GHz NEW, Secondary only
134.0 to 136GHz NEW, Primary
248 to 250 GHz NEW, Primary
4. The bottom 1MHz of each current segment above 71GHz should be
set aside for narrowband use, including beacons, except where
this conflicts with existing amateur uses. For example,
satellites on 24.048GHz, where the recommended segment remains 24.048
to 24.050GHz. This 2MHz segment should be able to support
adjacent Amateur and Amateur Satellite activity without mutual
interference and will bring close together all narrowband modes,
which should encourage further activity in this band.
5. Interim, both the old and new allocations should be shown in
the IARU Region 1 bandplans.

OPERATING PROCEDURES FOR METEOR SCATTER QSO'S
1. Introduction
The goal of the procedures described is to enable contacts to be
made by meteor scatter reflection (MS) as quickly and easily as
possible. As the reflections are of very short duration the
normal QSO procedure is not readily applicable, and special
measures must be taken to ensure that a maximum of correct and
unmistakeable information is received. The best meteor showers
are mostly strong enough to make some of these measures
unnecessary, but to encourage use of all generally listed showers
there is no reason why the suggested procedures should not always
be used.
2. Definitions
Two types of MS contacts, arranged in different ways, may be
distinguished:
a. A scheduled contact, where two interested stations agree in
advance on the mode (for example on telegraphy SSB or FSK441),
frequency, timing and period of the contact.
b. A non_scheduled contact, where a station calls CQ or responds
to a CQ call. Such contacts are often called "random MS".
3. Timing
It is recommended that stations use 2.5 minute periods on
telegraphy, 1 minute periods on SSB, and 30 seconds in FSK441.
This practice gives quite satisfactory results. However, growing
technical standards make it possible to use much shorter periods
and amateurs may wish to arrange 1 minute schedules for
telegraphy and shorter periods for SSB and FSK441 especially
during major showers.
a. All MS operators living in the same area should, as far as
possible, agree to transmit simultaneously in order to avoid
mutual interference.
b. If possible, northbound and westbound transmissions should be
made in periods 1, 3, 5 etc. counting from the full hour.
Southbound and eastbound transmissions should be made in periods
2, 4, 6 etc.
c. When arranging schedules, one or two hours duration for the
schedule may be used. Starting times should be on the hour (e.g.0000,
0100, 0200 UT etc.)
4. Scheduled duration
Every uninterrupted scheduled period must be considered as a
separate trial. This means that it is not possible to break off
and then continue the contact at a later time. The duration of
scheduled periods is usually one hour or, in some cases, two
hours.
5. Choice of frequency
a.Scheduled contacts
Scheduled contacts may be arranged on any frequency, taking into
consideration the mode/bandplan, but should avoid using known
popular frequencies and the random MS frequency segments 144.095
- 144.126 MHz (telegraphy) and 144.195 – 144.205 MHz (SSB).
b.Non_scheduled contacts
The frequency used for CQ calls for non_scheduled contacts should
be 144.100 MHz for telegraphy and 144.195-144.205 MHz for SSB and
144.370 for FSK441.
QSO's resulting from the CQ calls should take place in the 144.101-
144.126 MHz frequency segment (telegraphy).
Users of FSK441 should indicate the frequency they intend to
carry out the QSO by adding the three digits of the nominated
frequency. For example CQ383 indicates that the station will
listen on 144.383MHz for a subsequent contact.
On telegraphy, the following procedure should be used by the
caller to indicate during the CQ on which exact frequency he will
listen for a reply and carry out any subsequent QSO:
i) Select the frequency to be used for a QSO by checking whether
it is clear of traffic and QRM.
ii) In the call, immediately following the letters "CQ",
a letter is inserted to indicate the frequency that will be used
for reception when the CQ call finishes. This letter indicates
the frequency offset from the actual calling frequency used. For
instance, CQE CQE CQE would indicate that the operator would
listen on the calling frequency + 5 kHz.
A = 1 kHz Call would be CQA CQA CQA
E = 5 kHz Call would be CQE CQE CQE
N = 14 kHz Call would be CQN CQN CQN
Z = 26 kHz Call would be CQZ CQZ CQZ
In all cases the letter used indicates a frequency higher than
the CQ frequency.
iii) At the end of the transmitting period the receiver should be
tuned to the frequency indicated by the letter used in the CQ
call.
iv) If a signal is heard on this frequency it may well be a reply
from a station who has heard the CQ call and replies on the
frequency calculated from the letter used during this call.
v) When the caller receives a signal on the frequency indicated
during the call and identifies the reply as an answer on his CQ,
the transmitter is QSY'ed to the same frequency and the whole QSO
procedure takes place there.
Example: DF7VXS wishes to try a random MS experiment on
telegraphy, and wants to start with calling CQ. He first checks
his receiver in the range 144.101 - 144.126 MHz and finds a clear
frequency on 144.107 MHz. He decides to call CQ on 144.100 MHz,
and he must now add a letter to his CQ call to indicate on which
frequency he intends to listen. In this example he has chosen a
frequency offset of 7 kHz, and therefore he will have to include
the seventh letter of the alphabet, the letter "G", in
his CQ call. Note that the station receiving the CQ call will
reply on a frequency exactly 7 kHz above the one on which the CQ
call is heard.
If an operator instead of calling CQ wishes to listen for a CQ
call the following procedure should be used:
i) Listen on 144.100 MHz for telegraphy. (Note that when there is
considerable activity during major showers stations calling CQ
may QSY lower than 144.100 MHz in order to be on a clearer
frequency).
ii) When a CQ call is received, note the letter which follows the
letters "CQ" in the call. From this letter calculate
the frequency offset which the calling station will use for
receiving replies.
iii) QSY the transmitter higher in frequency by the number of
kHz's found, and transmit a reply during the appropriate period.
The format for the reply can be found in section 7.
iv) As the QSO will take place on this higher frequency, continue
to transmit and to listen (during the appropriate periods) on
this frequency. It may be that the station calling CQ will not
hear your first reply, but may do so during one or more
subsequent periods. Hence there is no need to return to the
calling frequency.
Example: You receive SM3BIU who is calling CQH CQH CQH. This
tells you that, regardless of the exact frequency SM3BIU is using
for his CQ, he will be listening for a reply exactly 8 kHz
higher, as H is the eighth letter of the alphabet. Having
established that the CQ was "CQH" you will call him 8
kHz up.
N.B. The letter system should not be used for SSB contacts!
(De Haan, September 1993)
6. QSO procedure for scheduled contacts and random operation
a. Calling
The contact starts with one station calling the other, e.g.
"DL7QY SM3BIU DL7QY ....". In telegraphy the letters
"de" are not used.
b. Reporting system
The report consists of two numbers:
First number Second number
(burst duration) (signal strength)
2 : up to 5 sec. 6 : up to S3
3 : 5 _ 20 sec. 7 : S4, S5
4 : 20 _ 120 sec. 8 : S6, S7
5 : longer than 120 sec. 9 : S8 and stronger
c. Reporting procedure
A report is sent when the operator has positive evidence of
having received the correspondent's or his own callsign or parts
of them.
The report is given as follows: "UA1WW I1BEP 26 26 UA1WW I1BEP
26 26 ....". The report should be sent between each set of
callsigns, three times for telegraphy, twice for SSB, and must
not be changed during a contact even though signal strength might
well justify it.
d. Confirmation procedure
i) As soon as either operator copies both callsigns and a report
he may start sending a confirmation. This means that all letters
and figures have been correctly received.
Confirmation is given by inserting an R before the report: "SM7FJE
G3SEK R26 R26 SM7FJE ...". A station with an R at the end of
the callsign could send "GW3ZTH I4BER RR27 RR27 ...".
ii) When either operator receives a confirmation message, such as
"R27", and all required information is complete he must
confirm with a string of R's, inserting his own callsign after
each eighth R: "RRRRRRRR HG5AIR RRRR ....". When the
other operator has received R's the contact is complete and he
may respond in the same manner, usually for three periods.
e. Requirements for a complete QSO
Both operators must have copied both callsigns, the report and a
confirmation that the other operator has done the same. This
confirmation can either be an "R" preceding the report
or a string of "RRRR..."'s as explained in paragraph 7.d.ii.
7. Missing information (telegraphy only)
If a confirmation report is received at an early stage in the
contact, the other operator has all the information he needs. The
following strings may then be used to ask for missing information:
BBB.... both callsigns missing
MMM....my callsign missing
YYY.... your callsign missing
SSS.... duration and signal strength missing
OOO.... all information complete
UUU.... faulty keying or unreadable
The other operator shall respond by sending only the required
information. This approach must be used with great caution to
prevent confusion.
Note. These procedures were adopted at the IARU Region 1
Conference in Miskloc-Tapolca (1978), later slightly amended at
the IARU Region 1 Conference in Noordwijkerhout (1987),
Toremolinos (1990), de Haan (1993) and San Marino (2002).

SUBJECT 50MHz BAND CODE OF CONDUCT
SOCIETY RADIO SOCIETY OF GREAT BRITAIN
Committee Committee C5.15 (VHF/UHF/Microwaves)
BACKGROUND
At the informal IARU Region 1 meeting, Friedrichshaven 2001,
there was a discussion regarding misuse by operators of the
intercontinental DX section 50.100 - 50.130MHz within the Six
Metre band. Those attending the meeting agreed that there was an
educational problem and reference was made to the UK Six Metre
Group voluntary operating code of practice for Six Metre
operators.
PROPOSAL
A. To include the UK Six Metre Group voluntary operating code of
conduct within the IARU Region 1 VHF Managers Handbook.
B. For VHF Managers and other officers of national societies to
actively promote the operating code of conduct in their
associated magazines or other medium (e.g. Web sites, packet
radio etc) as appropriate.
In summary the proposed code of practice could cover.
VOLUNTARY OPERATING CODE OF PRACTICE FOR SIX METRE OPERATORS.
Please read these recommendations carefully and try to adopt
their use in your everyday operating.
SIX METRES AS A DX BAND
It should be recognised by all 6M operators that Six Metres is a
DX band as well as carrying normal amateur radio QSO's. All 6M
operators should always treat each other with respect and
tolerance.
LOCAL BAND PLAN
Always respect your local band plan as issued by IARU.
LOCAL QSO's
Do not cause nuisance and disturbance to other operators with
local QSO's within the 50.100MHz to 50.130MHz DX window.
LEARN TO LISTEN
True Six Metre DX'ers spend about five percent of their time
transmitting while ninety-five percent of time is spent listening
and observing changing band conditions and propagation modes.
This will be far more effective than just calling CQ DX at random.
50.100 - 50.130MHz DX WINDOW
The DX Window is widely accepted and should, in principle, be
used for inter-continental DX QSO's only. The definition of what
constitutes a 'DX' station lies with an individual operator
especially when a station within your own continent constitutes a
new country.
50.110MHz INTERCONTINENTAL CALLING FREQUENCY
This should be used for long-range DX contacts only. Do not under
any circumstances engage in local continental QSO's on this
frequency even for a minute or two. Do not encourage pile-ups on
50.110MHz.
50.110MHz CQ'ING
LISTENING is the first rule of working rare DX on Six Metres. So
think twice before calling CQ on 50.110MHz. But the occasional CQ
is good as it can discover an unrecognised opening.
QSO TECHNIQUES
Follow the style and take the lead of the DX operator in
providing information. Otherwise keep it simple as there are
other stations waiting in line.
DX PILE-UP OPERATING
You should listen to the DX stations carefully and not continue
to call if they request a particular country or prefix if that is
not you. You should NOT call if you cannot hear the DX station!
SPLIT FREQUENCY OPERATION
When a DX station creates a large pile-up, split-frequency
operation is recommended. To minimise interference with other DX
stations operating simplex, it is recommended that a maximum
split of 10kHz is used.
DUPLICATE QSO's
It is always tempting to call a rare DX station every time you
hear it. This should be avoided as it means that you are taking
away the opportunity for the DX station to work a new station and
give them their first QSO with the DX country.
CW OPERATION
CW is probably the best mode of operation on Six Metres due to
the usually weak nature of many real DX openings.
FM QSO's IN EUROPE
All FM transmissions should be made above 50.300MHz for the
obvious reason that FM is wideband and could wipe out weak DX
signals.
MUTUAL INTERFERENCE
Proper adjustment of transmitters will minimise distortion and
reduce interference with operators on nearby frequencies. The
correct level of audio setting for the microphone in use is
essential for readability and minimal distortion. Linear
amplifiers should be only driven so that they
operate in the linear region and in any case should only be used
when propagation conditions require it. Please note that poor
receiver performance with respect to adjacent channel rejection
and overload will also limit your effectiveness.
This is a summary of the recommended Operating Code of Practice
as issued by the UKSMG. The full version can be found on the
Internet.
