Iceland on 4 m
Published on 21 February 2010 by TF2JB
On 19 Feb 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 31 Dec 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.

Proposal for 4 m in the USA
Published on 1 February 2010 by OZ2M
Justin, G0KSC, and William, AA4XT, forwarded a couple of emails about 4 m in the USA.

Justin, G0KSC, will pay a visit to William, AA4XT, soon to install a bunch of antennas and among those also one for 4 m.

Glen, K9STH, has 27 Jan 2010 submitted a proposal for changes around 4 m use to FCC.

"The 4 meter (70.000 MHz to 70.500 MHz) amateur radio band has been authorized in a growing number of European and African nations and establishing such privileges for amateur radio operators in the United States and other areas over which the Commission has jurisdiction would be of great benefit to those operators residing in such areas. The recent migration of broadcast television stations to primarily the UHF frequencies basically eliminates any probable interference to television channels 4 or 5 which otherwise might have occurred because the 4-meter band is located on frequencies that were allocated to television channel 4. Since the 4-meter amateur radio and does not fall in the 72.0 MHz to 76.0 MHz segment which is allocated to Operational Fixed and various mobile services there would be no potential co-channel or adjacent channel interference.

It is proposed to allow all classes of amateur radio operators operating privileges on this new band. However, it is suggested that Novice Class licensees be restricted to a lower output level than those allowed for Technician Class, General Class, Advanced Class, and Amateur Extra Class licensees. If the present power output limitations of 1500 W are granted to the higher class licensees then the Novice Class licensees should be restricted to no more than 200 watts power output as per most of the privileges granted those operators who hold a Novice Class license. If a lower power limit is placed on other classes of operator then the power output limits on the Novice Class should be reduced accordingly. For example, if power limitations of 200 W maximum output power be placed on Technician Class and higher licensees, then it is suggested that Novice Class licensees be held to no more than 25 W output.

One possible scenario would be to limit the Technician Class and higher licensees to 200 watts output power for a period of time (i.e. for 2 years) to determine any major interference problems which may occur by establishing these new operating privileges. At the end of that time, then the power output should be increased to the 1500 W output power now allowed to Technician Class and higher class licensees. The power output allowed for Novice Class operations would then be 25 W for 2-years increasing to 200 W after the 2-year time frame.


Whether or not the FCC will even actually consider establishing a new amateur radio band will have to be seen. But, nothing tried, nothing gained!

Change of forum usernames
Published on 20 January 2010 by Bo OZ2M
Hello all
From 1 January 2010 all usernames have to be authorised callsigns or SWL IDs.
We still need to identify these usernames: http://www.70mhz.org/forum/forummembers.php
You cannot change a username yourself. Therefore you need to contect me: oz2m mail dk Please send ID, username, and email address if it is old
Some already contacted me but because I accidently deleted all the usernames 22 Jan. I had to use an backup that did not contain most of the changes applied. Therefore, even if you did email me with the necessary information please verify that you are not on the above list.
You may receive this email even if you have an account with a callsign as the username if you have another account with a non-callsign username. In this case please also write me.
Accounts will be made inaccessible by end of January 2010 if the usernames have not been changed - ultimatively they will be terminated.

Another extension of the band in Denmark
Published on 18 December 2009 by Bo OZ2M
From 1 January 2010 the allocation in Denmark will be extended with another channel, i.e. 70,3 MHz +/-12,5 kHz. This means that five segments will become four:
69,9875 MHz - 70,0625 MHz
70,0875 MHz - 70,1125 MHz
70,1875 MHz - 70,3875 MHz
70,4125 MHz - 70,5125 MHz

70 MHz consultation in Bahrain
Published on 10 December 2009 by EI3IO
In a major spectrum consultation exercise launched by the Bahraini telecommunications regulator, the Telecommunications Regulatory Authority (TRA), seeks comments inter alia on whether all or parts of the band 69.95 - 70.5 MHz should be offered to the amateur service in Bahrain for propagation experiments. The consultation document (which also seeks comments on 500 kHz and 5 MHz) can be downloaded from http://www.tra.org.bh.

A new National Frequency Plan has also been published which allocates the band 50-50.5 MHz to the amateur service on a national primary basis and 50.5 - 52 MHz to the amateur service on a national secondary basis. New arrangements are also included for 136 kHz, 1.8 MHz 7 MHz and 430 MHz.

Czech radio amateurs will be QRV on 70 MHz again in 2010.
Published on 8 December 2009 by OK2POI
Czech telecomunications office informed, that we could get again 50 licensed for 4 m in 2010.
Freq. and power be same like in this year.

OE5QL beacon back on the air 24 h
Published on 3 December 2009 by Bo OZ2M

Peter, OE5MPL, wrote that the OE5QL beacon is now back on the air 24 h, but still with the 2 min four times per hour transmission sequence: HH:00-HH:02, HH:15-HH:17, HH:30-HH:32 and HH:45-HH:47.

Belgium on 4 m
Published on 20 November 2009 by Bo OZ2M

The Council of the BIPT decided in accordance with Article 13 of the Act of June 13, 2005 on electronic communications, to authorize all holders of a license class A (HAREC) to the frequency 69.950 MHz on a secondary basis Using a power of 10 W EIRP and a maximum bandwidth of 10 kHz. Radio Amateurs who wish to perform experiments at this frequency, are required to inform BIPT by letter or by e-mail address ram-nl@bipt.be. This Decision shall enter into force on the day it is published (Ed. 19 Nov. 2009).

Editor's note: It is great to see one more country getting access to 4 m. It is a pity that the regulator did not go for the Luxembourg allocation.

Meteor scatter QSOs and talk back
Published on 13 November 2009 by Bo OZ2M

I would like to draw all meteor scatter operators' attention to the MS Procedure section 7.4.9 VALID CONTACTS

"... However no recourse should be made during the contact to obtain the required information, change of frequency, antenna direction, etc. via other methods such as the DX Cluster, talk-back on another band, etc. Such secondary methods invalidate the meteor scatter contact. In essence: if anything concerning the ongoing QSO attempt is agreed through other means than the QSO attempt frequency a new start is required."

At the beginning of the year I asked in the forum how stringent this should be interpreted especially for firsts QSOs. The broad consensus was that a very harsh interpretation should be used.

Actually this does not apply to MS QSOs only but to any type of QSO.

There is no question that a "“first QSO" has a very special place in history and that no one else can make it. Therefore please make my job easy when I have to process your firsts claims.
