A new Next Generation Beacon
Today, Saturday 30 March, is the 56th anniversary of OZ7IGY and also the launch date for the new 70 cm beacon based upon the Next Generation Beacon platform: http://www.rudius.net/oz2m/ngnb.

The 70 cm beacon is now frequency and time locked to GPS. The sequence is timed to start at 00 second sending PI4 followed by a short pause then CW ID sending callsign and locator, then pause and carrier until next cycle. The nominal frequency remains the same, i.e. 432,471 MHz. To decode PI4 tune your receiver to 800 Hz below the nominal frequency, just like you do when you want to decode a normal CW signal at 800 Hz. On most radios this is a USB dial of 432.470.2.

At the same time the 6 m, 4 m and 2 m beacons have also changed MGM to PI4. The CW callsign, locator and carrier remain the same.

PI4 is a digital modulation (MGM) specifically designed with beacons and propagation studies in mind.

144 MHz Meteorscatter Sprint Contest 2013
MMMonVHF[1], in cooperation with the magazines DUBUS[2] and Funk-Telegramm[3], invites you to take part in the 6th edition of the “144 MHz Meteorscatter Sprint Contest” during the maximum of the Perseids meteor shower (PER).
Based on predictions from IMO[4] (the International Meteor Organisation), this maximum will occur on August 12, 2013, between 18:15 GMT and 20:45 GMT.

Contestperiod: August 11, 2013, 12:00 GMT – August 13, 2013, 11:59 GMT (end time last completed QSO).

Class 1: QRP (< 1.5 kW ERP).
Class 2: QRO (>1.5 kW ERP).
Stations can participate in one class only. No difference between single- or multi-operator stations or modes.

Exchange: Full callsigns, reports (e.g. 26 or R26) and final rogers (RRRR)[5].

Scoring: For each completed QSO you receive an amount of points that equals the distance between you and the station you completed with. A worked station only counts once, so no duplicates allowed.

Final scoring: The total score is the sum of all points you received for all completed QSO’s together.

Logs: Logs can be send via E-mail or regular mail. Your log has to be received before September 15, 2013. In case you have send your log by regular mail, the postmark will count. Logs received after that date will be considered as checklogs.
Logs via E-mail can be sent to: mssprint [at] mmmonvhf [dot] de; Subject: MSSprint “Call”.
Logs via regular post can be sent to: A.F. Veldhuijsen, PA4EME, Westlandstraat 9, 6137 KE Sittard, The Netherlands.

Be sure you log contains at least the following:
  • Your call, name, address and class you want to participate in.
  • Stations in Class 1 (QRP) have to state details about the equipment they used in form of used output power and antenna gain. If no data about your station is given, you will be placed in Class 2. The power used for the calculation of the Effective Radiated Power will be the power measured at the output of your transceiver or active amplifier(s);
  • The QSO list. As there are many logging programs available nearly every format is possible[6]. But make sure that the log will show at least: date, time (to be specific: end time), call, report send, report received, locator and distance (equals points).
  • With sending your log you also declare to have operated within the limits of your chosen Class, licence and local regulations when performing any activity that could impact your submitted score. Unsportsmanlike conduct can be ground for disqualification. Also you agree to have the log open to the public which might result in publishing your log on MMMonVHF or in the magazines DUBUS and/or Funk-Telegramm.
  • Reception of a log will be confirmed in the same way it was received.
Stories and pictures are welcome for the soapbox.

Conditions to be observed: The use of DX-clusters and chat-channels during the contest is only allowed in such way that there is no exchange of reports or other data from which the status of the QSO can be extracted. Limited information on the cluster (e.g. 12:00 DK5EW PA4EME JN48MB<MS>JO20WX) or chat (e.g. 12:00 PA2DW 144.355 CQ for MS Sprint) is allowed.
Selfspotting exceeding more than once every 15 minutes will be considered as unsportsmanlike behaviour.

Winner of the contest: The winner of the contest is the station with the highest amount of points. There will be a winner in each class. If two stations have the same amount of points, the position will have to be shared.

Special scoring for outside Europe stations: There will be a separate listing for stations outside Europe.

Certificate: All stations will receive a digital certificate showing the Class and ranking achieved.

Results: The results of the MS Sprint Contest will be published on the foreseen date that DUBUS magazine no. 4, 2013 will be issued: December 7, 2013. Results will be on-line that day on MMMonVHF. Printed versions will be in DUBUS magazine no.4, 2013 and Funk-Telegramm no. 1, 2014. VHF-editors around the world are free to publish the list as well provided the source and organizers are mentioned.

First WSPR beacon on 144 MHz in DL
On September 14, the first WSPR Beacon, DB0XIT, started working in Germany. WSPR is an abbreviation for “Weak Signal Propagation Reporter Network”. It is a network built to observe propagation conditions using weak beacons. DB0XIT is transmitting on 144,4890 MHz USB with 3 W horizontally polarized from Europe`s highest headgear in Göttelborn, Saarland. The antenna in use is a stacked angular dipole with omnidirectional characteristics at a height of about 457m over Sea level. The beacon is connected to the internet to observe propagation conditions in Europe. Interested people might have a look at the Internet[1,2] to get more details about WSPR. There you can also download the WSPR software for free in the case you want to get active on WSPR. 2m is not the only Band for WSPR. There are also beacons using shortwave bands. The Windows-Software distributed by the WSPR-Website supports working on all bands.

ARRL Microwave EME Contest
The ARRL Microwave EME contest took place on October 6/7 and stations from all over the world participated on frequencies ranging from 2,3 to 10 GHz.

This year, I took part in the 2,3 GHz band and found good activity despite the very high degradation due to the moon being near apogea. I made a total of 33 random QSOs: 32 in CW and 1 mixed SSB/CW.

Among the stations contacted, R3YA is a new DXCC for me and a first between ON and Russia on 13 cm. The smallest station contacted was PA7JB, who was surprisingly good copy with his little 2,4m offset dish and 100W only.

Antenna is a 3,6m mesh dish with circular polarization and power at the feedhorn is about 150W

7P8EME DXpedition
A lot of planning, accumulation of equipment and antenna development and cost has gone into the project over the last number of years. The total antenna systems has been re-developed and re-built by Pine, ZS6OB, since the last expedition to Namibia - that expedition was voted the 3rd best expedition world wide out of 69 expeditions for that year - no mean feat for a small group of ZS Radio Amateurs.

This will be a record setting International DXpedition for EME, as far as infrastructure, equipment, band coverage and antenna systems are concerned, which has ever visited another country - all with mobile equipment. The group will be covering all the VHF/UHF frequencies from 50 to 1 296 MHz [excluding 4 metres] on EME.

The venue will be at Ramabanta Trading Post. The Grid locator is KG30vi. The team will operate under the call sign 7P8EME.

There will also be limited HF mostly CW and 144 and 50 MHz - tropo and Meteor scatter operation to provide participation for local operators with smaller VHF and UHF stations.

The dates of the DXpedition are 14 to 26 September 2011. And the team is Pine, ZS6OB, (7P8EME); Wynand, ZS6ARF, (7P8QRO); Dick, ZS6BUN, (7P8BUN); Pieter, ZS6PA, (7P8PA); Dan, HB9CRQ, (7P8RQ) and Hermann, DL2NUD, (7P8HP).
Erika Pienaar and Lana Coats will be looking after the kitchen and feeding the team.

To support this DXpedition the South African Radio League has launched a fundraising initiative. You can assist by making a financial contribution.

ARISSat-1 is scheduled for deployment from the ISS next Wednesday Feb 16th.
It has a composite VHF downlink that will easily fit into the FUNcube Dongle receive spectrum. The telemetry is 1 kbit BPSK and can, of course, also be received with a normal SSB 2 metre receiver.

The expected signal levels from ARISSat should be similar to those we expect from FUNcube itself (and also eventually from UKube) and the team are keen to discover what will be the minimum and best type of antennas for schools to use with a FCD. Therefore user experience with the ARISSat signals will be very valuable in making this determination.

To encourage everyone to receive ARISSat signals we are offering a FUN reward for listeners!

There are a number of categories for this challenge –they include:
  1. The first FCD user, from each continent, who can post a spectrum recording of the received signal together with evidence of decoding the data using the ARISSat software and of sending it to the ARISSat data warehouse.
  2. The first non-FCD user, from each continent, who can provide evidence of having decoded the signals and of sending it to the ARISSat data warehouse.
  3. The listener, using a FCD or not, who can demonstrate satisfactory reception of the telemetry in the same ways as described above, using the "smallest" possible receive antenna. The actual closing date for this part of the challenge will be announced later.
All other entrants who can demonstrate that they have been having FUN!
Please submit your "entries", including your location, station details (including FCD serial number where applicable), postal address and reports to g0auk [at] amsat [dot] org.

Good luck,

70 MHz in Iceland
The national association of Icelandic Radio Amateurs, Í.R.A., is pleased to announce that as of December 13, 2010 continued access for Icelandic licensees has been secured on the 500 kHz, 5 MHz and 70 MHz bands. In a letter from the Icelandic Post and Telecom administration dated December 13, 2010 access to the 500 kHz and 70 MHz bands previously granted on February 19, 2010, and to the 5 MHz band, previously granted on January 1, 2008 – all due to expire on December 31, was extended for two years, to December 31, 2012.
Privileges and access to 500 kHz and 70 MHz remains unchanged (see below). Nevertheless, Í.R.A. is delighted to report that we have been granted 150 kHz in the 5360-5410 kHz band, as a replacement for eight fixed channels, previously permissible. Maximum power allowed on 5 MHz was though reduced from 200W to 100W (20 dBW).
THE 4 mETER allocation. Frequency span: 70.000-70.200 MHz. Access is granted on secondary basis. Maximum bandwidth is 16 kHz and power limit is 100W. Licensees need to apply to the PTA for a special license. The experimental license is open to both “N” and “G” license classes.

Radio amateurs in the Sultanate of Oman hope to work you on the "Magic Band."
QRP moonbounce on 5.7 GHz
Hi all,

Good activity on 5,7 GHz EME was expected during the second week-end of july, thanks to the coordination of G3LTF.

I decided to have a try, using my 2,3 m offset dish and the system used normally for tropo and rain scatter.
This system consists of a transverter kit from DB6NT and a modified surplus 6 GHz amplifier, giving about 8 W output.
Noise figure of the system is around 1 dB.

The 5,7 GHz transverter has an output on 144 MHz and is followed by another transverter 144 to 28 MHz.
There are various 28 MHz outputs. One output goes to a yaesu FT840 HF transceiver.
Another output goes to an SDR, and another one to a calibrated 28 MHz receiver, allowing precise measure of sun noise and moon noise.
During operation, permanent reading of moon noise allows perfect aiming of the dish and confirms that the system is working alright.

Most EME stations use circular polarization, so a "septum feed" was built following a description by OK1DFC.
Dimensions were adapted in order to illuminate correctly the offset dish.

After optimizing carefully the position of the feed, I could measure 0,5 to 0,6 dB of moon noise versus cold sky. Sun noise was a good 10,5 dB, meaning that the receiving side was working correctly. The feed has some sidelobes and is far from perfect, but efficiency seems to be quite good.

Now the results: during the week-end, 13 stations from Europe, USA and Japan were heard.
To my great surprise, some of them were even able to decode my QRP signal and 3 good QSOs resulted !!!

Conclusion: this band offers very interesting possibilities for the experimenter.
Tropospheric propagation and rain-scatter allow surprisingly good distances even with very small set-ups.
The above results also shows that EME contacts are possible with very low power, thanks to the amazing receiving capability of some stations.

ON0VHF and propagation....
DL7AFB wrote tu us about ON4VHF....

Dear OM's,
during last VHF contest I made a record of your beacon ON0VHF, which is always audible from my fieldday location in JO62JA, 588km away. Conditions were moderate, but the beacon was readable anyway.
Please listen to the sound sample on YouTube: http://www.youtube.com/watch?v=neVnSNYYmNE
best regards

First contact JA-ON on 3cm

Yesterday Eric, ON5TA had a first QSO with JA on the 3cm Band EME. 

The QSOs needed quite a lot of preparation work, because japanese hams are only allowed to transmit on 10.450 MHz, not on 10.368 MHZ.
So a new receiving system had to be build here in order to be able to make "crossband" contacts.

We also needed a common window and the best possible moon conditions. These conditions were met yesterday, but wind could have been a problem.
The japanese hams used big 5 to 6m dishes, very sharp on 3 cm, which make aiming to the moon very difficult with the slightest wind.
As you know, we had wind here yesterday evening, but it was manageable during the QSOs

This why JA4BLC is talking about "a miracle" in his mail. HI !

A little piece of the mail of JA6CZD
Hi Eric,
Yes, QSO by ON5TA-JA6CZD is the first ever between ON-JA on 3cm EME, GREAT!
Me too very much pleased to work you. You are MY #3 on 3cm EME and good signal as well as G4KGC I worked 30minutes before.
It was miracle no wind happened during our QSO.


Iceland on 70MHz
On February 19, 2010 The Post and Telecom Administration in Iceland granted a temporary experimental access to the 4 meter band in Iceland. The permit is valid until December 31, 2010.

Frequency span: 70.000-70.200 MHz. Access is granted on secondary basis. Maximum bandwidth is 16 kHz and power limit is 100 W.

Licensees need to apply to the PTA for a special license. The experimental license is open to both “N” and “G” license classes.
Congratulations Dirk
Dirk, ON5GS, went on a Dxpedition last year november, during the BCC Meteor contest as EI/ON5GS/P. He activated the squares IO55 and IO65.

With a score of 128 QSO he is the winner of this contest in the Single OP class.

First VK-ON on 3cm..

On November 5th Eric ON5TA managed to have a QSO with Charlie VK3NX.
They had both problems with the automatic moon tracking system, but the could finish the QSO. 

A few senteces from the mail received from Charlie:
Firstly  TU TU !!
What a wonderful signal you have.  For me it was “speaker” copy  (no need for tin cans)
I find it very hard to believe you only have 2.3m dish and 30 W.  It is a credit to your “attention to detail”. Your signal was “huge”!
I have only worked 14 initials on 10 GHz  but your’s was easier to copy than some “bigger stations”
I could only just hear my echoes today  but I heard you every period.  A few times I stopped hearing you in the middle of a sequence,  I guess wind at your end?...  or perhaps you do what I do and need to re-align on moon noise in the middle of a sked?
Thank you for trying again and I am very happy that we have had such good success (now  that I was looking on the right freq...Hi..Hi..)
Unfortunately halfway through the sked for the 1st time ever I “blew up” the regulator on my Azimuth control!...I had to operate the Az  movement in “Slow mode”  so it took a lot of effort to  keep on the moon......and also Murphy tried hard to stop me because TWTA Helix current kept “tripping” the alarm circuit  because of moisture in the air.......
....but none of this matters,  because of the wonderful success.  It  is a “ majic” achievement for me each time I work a new station. 
Many tnx  and hpe to cuagn on 10 GHz  and perhaps another band?

3 cm QSOs between ON - VE
A lttle 3 cm TWT amplifier was installed yesterday on the back of my 2.3 m offset dish.
I also replaced the coax relay with a waveguide switch + W/G preamp.
Have now 1.3 dB moon noise and abt 13.4 dB sun noise/cs, which is much better than before.
Contacted this morning: F2TU, OK1KIR, F5JWF (#), IQ4DF, W5LUA (#), VE4MA (#) and ES5PC (#).
These could be the first 3 cm QSOs between ON - VE and ON - ES.
Thanks to all for a very enjoyable morning !

World Moon Bounce Day - June 27th 2009
On Saturday, June 27th, many of the world’s large parabolic antennas (sometimes called dishes) will stop their normal space work and swing around to track the moon when it rises. EOA volunteers will then use the EME or Moon Bounce transmissions to link up with other dishes worldwide via the moon. Signals are literally being bounced off the moon’s surface and back to other stations on earth where they are received some 2.5 seconds later.

There has never been so many dishes pointed at the moon since the lunar landings and possibly this will even break that record.

4 meter beacon in OE

We are happy to announce, that we received a license to operate a beacon on the 4 m band.

  • Callsign: OE5QL
  • The beacon frequency is: 70,045 MHz
  • Locator: JN78CJ
  • Height: 840m ASL
  • Antenna: Half-Wave Vertical

This is no Amateur Radio Call the Austrian PTT said, it is an Experimental Operation Radio Call.

Well, there are some restrictions:

  • Time limit is 1 June and until 31 August 2009.
  • Transmission is only 2 minutes per sequence between 04:00 and 19:47 UTC.
  • Each sequence begins at full hour +00 min., +15 min., +30 min. and +45 min, e.g. 04:00-04:02, 04:15-04:17, 04:30-04:32 and 04:45-04:47.
  • Transmission power is 1 W ERP the first minute of each sequence and 5 W ERP the second minute of each sequence.

If the beacon does not interfere with services outside of Austria, an extension is possible after August 2009 the Austrian PTT said.
Anyway after August 2009 we will try to negotiations for 24/7 duration period for the beacon.
