Dear radiofriends,
With pleasure we send you our new IARU-C5 Newsletter. It will be the first one in my new role as
manager of C5, so a little introduction may be useful.
Introduction Dick PA2DW
Originally I was educated on the Univerisity of Applied Science in Amsterdam, to be a radio-officer on
the Merchant marine. I sailed in a great part of the seven seas in the early 80-ies.
In the last 11 years of my daily life, I have been a director of a specialized school for fine mechanical
engineering, the Leidse instrumentmaker School (LiS). This school was emerged from the laboratories
of the University of Leiden and was being established in 1901 by prof. Kamerlingh Onnes. In 1908 it
has been briefly the “coldest place on earth” when Kamerlingh Onnes succeeded in liquifying
Helium. The last gas that was never being made liquid before.
The discovery of superconductivity was a big achievement of Kamerlingh Onnes, in close
collaboration with the practical hands of the students of the LiS, whom Kamerlingh Onnes called
“thinking workers”. Later the discovery of superconductivity appeared important for making the
huge magnet coils used in MRI-technology and the Hydron-collider at CERN in Geneva, and many
other applications where superconductivity is being required.
It was my privilege to have worked in this school, but as for all of us, the moment of retirement
comes and for me that was December 2019. And since I liked to remain as active as possible, I
thought it to be a good idea to step in the tracks of my elmer Arie Dogterom, PA0EZ.
Ever since I got my first license, in 1976, I have been active on VHF. The only HF bands that I found
attractive, are 160 and 40 meters, due the special propagation and the difficulty of making real DX on
those bands. But 144 MHz was my choice for many years, with homebrew gear I made numerous
QSO’s on Meteor Scatter and EME.
Later, in 2008, I started my activity on 1296 MHz EME, mainly inspired by the project at the 25m dish
in Dwingeloo, in which I got involved as chairman of VERON in 2005. I still enjoy being active on both
144 and 1296.
Our challenges for the years to come
From what I can see now, our hobby is likely (going to be) under a lot of pressure and various positive
and negative influences. Not only from outside, but certainly also from within our own circles.
Besides the fact that the average age of the group of radio amateurs is only getting higher and
higher, we have to face pressure on our spectrum and new developments in the way we make radio
contacts, such as WSJT and its never ending row of Machine Generated Modes.
I think these developments call for a drastic overhaul of our bandplanning, especially concerning the
frequency’s under 1 GHz, but certainly not restricted to that. Because on the one hand we have large
portions of our spectrum that are hardly in use and on the other hand we need to find a good place
for all these new emerging ways of use of the radio waves, such as WSJT and digital ATV.
We should be brave enough to review all our bandplanning and make choices that will help us in the
future. Also we have to review the procedures in order to aloow for making rapid adaptions to our
bandplans if required. The way we organize it now is way too conservative. Also, we should not be
scared to share portions of the allocated spectrum, with second of even more users, provided we can
live next to each other. That does not mean we should give up our rights, but showing our willingness
to investigate the possibilities and gain goodwill.
My prediction is, that on the upcoming General Conference we will have lots of these issues +-on the
menu, so proposals and suggestions are now certainly important to start thinking about!
I am looking forward to a fruitful collaboration with you all. Together we make sure the future looks
bright again!

New contest rules
Following the decision of the Virtual General Conference the C5 Contest Working Group prepared
the new Contest Calendar and amended the contest rules.
The VHF Handbook will be updated with those new contest rules. This will be communicated when
New Contest Calendar
It has been introduced two new dates for the 50 and 70 MHz MGM Contests and the 50/70 MHz
contest are separated. The new dates are:
• IARU Region 1 50 MHz MGM Contest will begin on the third Saturday of April
• IARU Region 1 70 MHz MGM Contest will begin on the third Saturday of May
• IARU Region 1 50 MHz (CW-SSB Only) Contest will begin on the third Saturday of June
• IARU Region 1 70 MHz (CW-SSB Only) Contest will begin on the third Saturday of July
• The IARU Region 1 145 MHz contest will begin on the first Saturday of September
• The IARU Region 1 UHF/Microwaves contest will begin on the first Saturday of October.
Each contest will start at 14:00 UTC on the Saturday and end at 14:00 UTC on Sunday.
MGM Contests on 50 and 70 MHz
About the new MGM contest the basic rules can be summarized in this way :
All Machine Generated Modes (MGM) are valid:
• MGM recognized MGM modes are e.g. FT4, FT8, FSK441, ISCAT, JT65, RTTY, PSK.
• CW is not an MGM mod
• EME (moon bounce) QSOs are not permitted
Sections :
• 50 MHz band:
o SINGLE (SO-MGM): single operator entries MGM
o MULTI (MO-MGM): multi operator entries MGM
o 6HOURS (6H-MGM): 6 hours entries MGM
• 70 MHz band:
o SINGLE (SO-MGM): single operator entries MGM
o MULTI (MO-MGM): multi operator entries MGM
• Only one scoring contact may be made with a given station

• Report (as appropriate for the mode in use) and 4-character Locator (e.g. IO91). Serial
number is not required
• One point per kilometre.
• Score is total kilometres worked multiplied by the number of large Locator Squares (e.g.
IO91) worked. Distance is calculated to the centre of the large Locator Square (e.g. IO84MM
to IO91MM). A QSO between stations in the same large Locator Square will count for 50
• Stations taking part in the contest must not simultaneously TX on more than one frequency
and/or on more than one FT8 channel (per band). Fox/Hound mode is not permitted.
• For the 2021 year, ADIF files can be directly uploaded to the entry robot at
https://iarulogs.rsgbcc.org/cgi-bin/vhfenter.pl (thanks to RSGB)
Stations eligible to win a prize
It is asked to all the VHF & Up contest managers to inform participants about this new rule:
In every category of all the IARU Region 1 Contests the stations willing to win their
categories must submit their logs individually to the IARU R1 Contest Robot within the
23:59 UTC of the Monday after the contest (34 hours); only these stations will be eligible to
the victory and prizes.
If the first station in the classification did not send his log before the deadline to be eligible
for the victory (34 hours), then the first station which sent his log within the 34 hours
deadline will be the winner. (VGC 2020).
IARU VHF & Up Trophy
C5CWG decided to use 2021 year to start to collect all the information needed, prepare the
contest robot, then start with the official IARU Reg. 1 VHF & Up Trophy in 2022.
The following contests are valid for the Trophy :
• 1 st weekend of March : 1st Subregional contest 145 MHz & Up
• 1 st weekend of May: 2nd Subregional contest 145 MHz & Up
• 1 st weekend of June : Microwave Subregional Contest 1296 MHz and up
• 1 st weekend of July: 3rd Subregional contest 144 MHz & Up
• 1 st weekend of September : IARU Region 1 145 MHz contest
• 1 st weekend of October : IARU Region 1 UHF & Up Contest (435 MHz & up)
• 1 st weekend of November : Marconi Memorial Contest 145 MHz (Only CW)
The normal rules like described in the contest rules of the IARU Region 1 VHF Handbook (Part 3,
Section 1) are applicable.
If participating in the one of the contests in the list in multiple bands, a different log is needed per
The categories are the same as used in IARU Region 1 145 MHz (September) and UHF/Microwave
(October) Contests. In the IARU R1 Trophy the Overall category is not included.
You need to participate on the same band and category on at least all the contests in the calendar
except one.
The final score is the sum of the points of each contest where the station participated.
All those changes will be published in a new VHF handbook (version 9.01) and
on the IARU-R1 website as soon as possible.
