I have assembled my UBITX V4 and V3.
The version 4 is working perfectly.I am working on increasing the output power to some 50w
B y default the O/P is 10 w on average.
Is having some audio problems with the V3 one as the audio amplifier blew out.I have found the culprit and doing needful to replace it.
Please note the Ubitx is a general HF coverage transceiver in kit form and it costs some 139 US with shipping included.

Emcom organisations across the globe
International
The Global Amateur Radio Emergency Communications Conference (GAREC) is held in a new location yearly by the International Amateur Radio Union (IARU), hosting discussion and coordination of large-scale and cross-border amateur radio emergency response.
IARU Emergency CommunicationsSite http://www.iaru.org/emergency-communications.html
France
Fédération Nationale des Radioamateurs au service de la Securité Civile
Australia
HAMNET, the Emergency Communications division of the South African Radio League (SARL), provides communications for emergencies and can mobilise experienced communicators who with their own radio equipment will back up official channels or take over when all else fails.

Malaysia
In Malaysia, Malaysian Amateur Radio Emergency Service Society (MARES) is a registered organization under Malaysian Registrar of Societies (RoS). It also a member of Malaysian Amateur Radio League (MARL). MARES provide voluntary emergency communications during disaster. Besides coordinating emergency communication, MARES also conducting classes and other common radio amateur activities such competition, fox hunting, flea market, eye-ball meet etc.

Organisasi Amatir Radio Indonesia
he Organisasi Amatir Radio Indonesia (ORARI) (in English, Amateur Radio Organization of Indonesia) is a national non-profit organization for amateur radio enthusiasts in Indonesia. According to a 2000 census compiled by the International Amateur Radio Union, Indonesia has the thirteenth-largest population of amateur radio operators in the world.[1] A key membership benefit of the ORARI is a QSL bureau for those Indonesian amateur radio operators in regular communications with other amateur radio operators in foreign countries. The ORARI represents the interests of Indonesian amateur radio operators before Indonesian and international regulatory authorities. ORARI is the national member society representing Indonesia in the International Amateur Radio Union.http://www.orari.or.id/
United Kingdom
In the United Kingdom Radio Amateurs Emergency Network (RAYNET) provides the organizational backbone of their amateur radio emergency communications groups along with the Radio Society of Great Britain (RSGB). It was formed in 1953 in the aftermath of the North Sea flood of that year.
United States of America
In the United States, there are two major methods of organizing amateur radio emergency communications: the Amateur Radio Emergency Service (ARES), an organization of amateur operators sponsored by the American Radio Relay League (ARRL); and the Radio Amateur Civil Emergency Service (RACES), a standby replacement radio service regulated by the Federal Communications Commission. Operations under the RACES rules requires preregistration with a local civil defense organization, to allow continued operation under Part 97.407 of the FCC regulations in the event the Amateur Radio Service is ever shut down by presidential order. Thus ARES and RACES involvement within the same area are usually intertwined, with many governments requiring membership and service in that locale's ARES organization to allow operations within the Amateur Radio Service as well. Many government Emergency Operations Centers, Red Cross Chapters and National Weather Service facilities have permanent Amateur Radio stations installed for such operations.
The ARRL provides extensive documentation on how to conduct emergency radio communications, including its Public Service Communications Manual.
Radio clubs independent of the ARRL and ARES also participate in emergency communications activities in some areas, and some non-radio organizations have their own amateur arm. The Department of Defense sponsors the Military Auxiliary Radio System(MARS) program which utilizes Amateur Radio operators for emergency communication using military radio frequencies. The National Weather Service Skywarn weather-spotter program has a strong amateur radio contingent. And amateurs dedicated to the Salvation Army are organized under their Salvation Army Team Emergency Radio Network program.
Emergency communications and disaster assistance is usually done in conjunction with volunteer disaster relief organizations such as the American Red Cross, the Salvation Army, local government emergency management agencies, as well as volunteer fire departments and ambulance corps.
The ARRL has memoranda of understanding with numerous agencies expected to receive services,[9] including the American Red Cross and Salvation Army and is a partner in the Citizen Corps program of the Federal Emergency Management Agency (FEMA). The ARRL also is a member of the National Voluntary Organizations Active in Disaster (NVOAD) and conducts emergency communications certification courses for interested Amateur Radio operators.
Canada
In Canada, Amateur Radio Emergency Service (ARES) is sponsored by the Radio Amateurs of Canada. Often other less formal networks of volunteer radio operators are also used and organized by the local emergency response agencies in conjunction with local ham radio operators. As in the United States, Radio Amateurs of Canada has memoranda of understanding with numerous agencies expected to receive services[2], including the Canadian Red Cross and Salvation Army.

The same frequency 144.550 Mhz will be used.
I shall be sending out the procedures in the coming days.
In the meantime any suggestion is welcome.
============================
Comme nous l’avions fait la dernière fois, je compte faire un exercice similaire à celui de l’année dernière, qui n’utilise pas le système de répéteurs. Nous allons mettre en pratique les leçons apprises la dernière fois.
Je choisis le dimanche 3 mars 2019 à partir de 9h00.
La même fréquence 144,550 Mhz sera utilisée.
J'enverrai les procédures dans les prochains jours.

Areg first workshop/le premier atelelier de travail de areg
Gentle reminder about our forthcoming AREG workshop.
We shall be doing winlink digital mode instead of FT8 as winlink is much more useful for emcom and also ,we already have two Mauritian gateways -3B8DU and 3B8FO.
The newly licensed amateurs are also welcome.It will be an opportunity for them to build friendship with other hams.
=================================
Rappel en douceur sur notre prochain atelier AREG.
Nous ferons le mode numérique winlink au lieu de FT8 car winlink est beaucoup plus utile pour emcom et nous avons déjà deux passerelles mauriciennes -3B8DU et 3B8FO.
Les amateurs qui ont récemment obtenu leur licence sont également les bienvenus.
