Activation of 3A
Submitted by: ON4AVJ

From August 11 to August 13 3A/ON7EQ will be active from 3A in JN33 square.
Activation on MS 70 Mhz (and possibly 50 MHz if there is interest) next Perseid shower, August 12th & 13th, is hereby confirmed.
Hans ON5AEN, who has MS experience on 2m, will join to operate the station. More info - like frequencies, sequences etc… - will be released later via ON4KST chat.

Meanwhile, already prepared some theoretical range prediction. As you are probably aware, Monaco is only 3 kms long and 300m wide, with mountains towards the north and west… not the best place for a low take-off angle! According to our spot where we have chosen to set up the station and the theoretical models, we expect a range like depicted on the map - as you can see ON will be ideally within reach!

73 and looking forward to cu in MS!

UK Amateurs Losing Access to Part of 2.3 GHz and 3.4 GHz Bands
Submitted by: ON4AVJ
UK telecommunications regulator Ofcom has announced that it’s ending Amateur Radio access to significant portions of the 2.3 and 3.4 GHz bands.
The action, announced on April 7, came in the wake of a year-long “consultation” — a rule making proceeding — that involved the release by the Ministry of Defence of 40 MHz of spectrum at 2.3 GHz and 150 MHz of spectrum at 3.4 GHz. Amateur Radio is secondary on the bands.

Amateur Radio will lose privileges on frequencies in the two bands that overlap with spectrum that Ofcom plans to award for “new civil uses” — 2350 to 2390 MHz and 3410 to 3475 MHz. The announcement gives radio amateurs at least 12 months’ notice, but radio amateurs must comply immediately with procedures to avoid interfering with other users; ham radio occupants of 2310 to 2350 MHz will have to register their use and provide details to Ofcom.

Amateur Radio will retain access to the adjacent bands, but Ofcom has put procedures in place to remove even those frequencies from Amateur Radio access, if necessary in the future. Ofcom said earlier this year that with military and other government use of the 2.3 and 3.4 GHz spectrum ending, “we believe an award of the spectrum for high power use is likely to deliver greater benefit to UK consumers and citizens than continued amateur use.” Ofcom was required by the Ministry of Defence to adequately protect its systems from Amateur Radio interference in both the released spectrum and in adjacent bands.

“The MoD’s plans are part of a government commitment to release 500 MHz of spectrum by 2020,” Ofcom explained in its order. “This commitment to opening up spectrum for new civil uses is based on growing demand from UK consumers for spectrum-hungry devices such as smartphones and tablets.” Ofcom said that use of mobile data devices more than doubled in the 18 months leading up to January 2012. “Indeed, the 2.3 and 3.4 GHz bands are identified in Ofcom’s ‘mobile data strategy’ as having the potential to support even better mobile data services for citizens and consumers in the coming years,” the regulator said.

Ofcom said it was making 2300 to 2302 MHz available for amateur use, but licensees first must obtain a Notice of Variation to their licenses. Hams in the US have secondary access to 2300 to 2310 MHz, 2390 to 2450 MHz, and 3300 to 3500 MHz. — Thanks to RSGB, Ofcom

A new Next Generation Beacon
Submitted by: ON4AVJ
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.

Download PI-RX to decode PI4: http://www.rudius.net/oz2m/ngnb/pi-rx.

PI4 encoding examples in Arduino C, Atmel C, Delphi Pascal, Microsoft Visual Basic and Microsoft C++: http://www.rudius.net/oz2m/ngnb/software.htm.

PI4 online encoding and frequency calculation: http://www.rudius.net/oz2m/ngnb/pi4encoding.php.

PI4 specification: http://www.rudius.net/oz2m/ngnb/pi4.htm PI4 is a cousin of JT4, JT9 and WSPR.

144 MHz Meteorscatter Sprint Contest 2013
Submitted by: ON4AVJ
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.
