European Anchovy Engraulis Encrasicolus (Linnaeus, 1758) From
European anchovy Engraulis encrasicolus (Linnaeus, 1758) from the Gulf of Annaba, east Algeria: age, growth, spawning period, condition factor and mortality Nadira Benchikh, Assia Diaf, Souad Ladaimia, Fatma Z. Bouhali, Amina Dahel, Abdallah B. Djebar Laboratory of Ecobiology of Marine and Littoral Environments, Department of Marine Science, Faculty of Science, University of Badji Mokhtar, Annaba, Algeria. Corresponding author: N. Benchikh, [email protected] Abstract. Age, growth, spawning period, condition factor and mortality were determined in the European anchovy Engraulis encrasicolus populated the Gulf of Annaba, east Algeria. The age structure of the total population is composed of 59.1% females, 33.5% males and 7.4% undetermined. The size frequency distribution method shows the existence of 4 cohorts with lengths ranging from 8.87 to 16.56 cm with a predominance of age group 3 which represents 69.73% followed by groups 4, 2 and 1 with respectively 19.73, 9.66 and 0.88%. The VONBIT software package allowed us to estimate the growth parameters: asymptotic length L∞ = 17.89 cm, growth rate K = 0.6 year-1 and t0 = -0.008. The theoretical maximum age or tmax is 4.92 years. The height-weight relationship shows that growth for the total population is a major allometry. Spawning takes place in May, with a gonado-somatic index (GSI) of 4.28% and an annual mean condition factor (K) of 0.72. The total mortality (Z), natural mortality (M) and fishing mortality (F) are 2.31, 0.56 and 1.75 year-1 respectively, with exploitation rate E = F/Z is 0.76 is higher than the optimal exploitation level of 0.5. -

How to Configure Radios for Use with Repeaters
Concept of How to Configure Your Handheld and Mobile Radio for Use on a Repeater System VA6RPL Peter LaGrandeur Calgary Amateur Radio Association 2015 Learning Conference Limitations of “Standalone” Radios such as Handhelds and Vehicle Mounted Mobiles. Short Range of Coverage Signal easily blocked by major obstacles such as mountains, valleys, urban infrastructure What is a “Repeater” Radio? A repeater is basically a two way radio that receives a signal on one frequency, and simultaneously retransmits it on another frequency. It can retransmit with much greater power than received, and can send over a much wider area. A good example is where users are scattered in various areas separated by mountains; if a repeater is situated on top of a central mountain, it can gather signals from surrounding valleys, and rebroadcast them to all surrounding valleys. Handy! From there, repeater stations can be “linked” together to connect a series of repeater radios, each in a different area. With this, every time a user transmits on his mobile or handheld, his call will be heard simultaneously over all the repeater transmitters. And, yes! Repeater stations can now be connected via the internet. This internet linking is called IRLP – Internet Relay Linking Project. For example, a repeater in Calgary can link, via the internet, with an IRLP repeater anywhere in the world. You can carry on a two way radio conversation with someone in a faraway land with the assistance of the internet. Locating of Repeater Stations The higher the better. Yes, there are even satellite repeaters for amateur radio. In places that afford the best coverage in as many directions as possible. -

The FCC Filing
Dr. Theodore S. Rappaport, PE PO BOX 888 Riner, Virginia 24149 [email protected] November 10, 2018 Commissioners Federal Communications Commission 445 12th Street, SW Washington, DC 20554 Dear FCC Commissioners: This is a notice of ex parte, based on email communication I had with the CTO of the FCC, Dr. Eric Burger, on November 8, 2018, his reply on November 10, 2018, and my reply on November 11, 2018. The email communication is centered around a posting that appeared on the FCC ECFS system on November 7, 2018, and is part of an ongoing proceeding at the FCC, NPRM 16-239, that I and thousands of others view as a direct threat to the national security interests of the United States, as well as being detrimental to the hobby of amateur (“ham”) radio. Public comments made in FCC’s NPRM 16-239, and in FCC proceedings RM-11708, RM-11759, and RM-11306 proposed by the American Radio Relay League, show the vast number of rule violations and national security threats that continue to go unaddressed by the FCC. Commenters such as me view the lack of FCC acknowledgement of these problems as jeopardizing the safety of US citizens. NPRM 16-239 attempts to remove a limit on the baud rate of High Frequency (HF) shortwave transmissions, without first addressing ongoing rule violations pertaining to proper usage of the amateur radio service, the use of obscured, private messaging which is forbidden in Part 97 rules and creates national security concerns, as well as other violations. If allowed, NPRM 16-239 would perpetuate the current violations, and would authorize obscured transmissions of unlimited bandwidth over the global airwaves, further increasing the danger to our national security, since these transmissions cannot be intercepted or eavesdropped by other amateur radio operators or the FCC. -
Global Maritime Distress and Safety System (GMDSS) Handbook 2018 I CONTENTS
FOREWORD This handbook has been produced by the Australian Maritime Safety Authority (AMSA), and is intended for use on ships that are: • compulsorily equipped with GMDSS radiocommunication installations in accordance with the requirements of the International Convention for the Safety of Life at Sea Convention 1974 (SOLAS) and Commonwealth or State government marine legislation • voluntarily equipped with GMDSS radiocommunication installations. It is the recommended textbook for candidates wishing to qualify for the Australian GMDSS General Operator’s Certificate of Proficiency. This handbook replaces the tenth edition of the GMDSS Handbook published in September 2013, and has been amended to reflect: • changes to regulations adopted by the International Telecommunication Union (ITU) World Radiocommunications Conference (2015) • changes to Inmarsat services • an updated AMSA distress beacon registration form • changes to various ITU Recommendations • changes to the publications published by the ITU • developments in Man Overboard (MOB) devices • clarification of GMDSS radio log procedures • general editorial updating and improvements. Procedures outlined in the handbook are based on the ITU Radio Regulations, on radio procedures used by Australian Maritime Communications Stations and Satellite Earth Stations in the Inmarsat network. Careful observance of the procedures covered by this handbook is essential for the efficient exchange of communications in the marine radiocommunication service, particularly where safety of life at sea is concerned. Special attention should be given to those sections dealing with distress, urgency, and safety. Operators of radiocommunications equipment on vessels not equipped with GMDSS installations should refer to the Marine Radio Operators Handbook published by the Australian Maritime College, Launceston, Tasmania, Australia. No provision of this handbook or the ITU Radio Regulations prevents the use, by a ship in distress, of any means at its disposal to attract attention, make known its position and obtain help. -
