ET3AA - Addis Ababa Institute of Technology, Addis Ababa, Ethiopia- Aug. 3 thru Aug.5, 2011

During my return trip from the ST0R -  Republic of South Sudan DX-Pedition, I met up with Sid May (ET3SID) who is the ET3AA - Addis Ababa University - Institute of Technology station trustee. We discussed a few topics on how I met help the students and the school. After this discussion, we decided I would help by providing a nice summer workshop for the students who wanted to participate (a total 13-20 students participated at various times during the 2 days on-site).

The hands on work shop included the following activities:

  •  Coax End Preparation Techniques; RG-8, etc.

  •  Antenna Design Theory and Advantages of each antenna type; Basic Dipole, Vertical, Slopper, Inverted Vee and Inverted L
  •  Using Software to design wire beams; designed a two element 40 meter beam and three element 15 meter beam
  •  Constructed a dipole antenna for 21.3 Mhz using existing materials in the shack and tested it in different configurations (i.e. Basic Dipole, Vertical, Slopper, Inverted Vee and Inverted L) - included on the air performance testing with other foreign ham radio stations
  •  Examined the surrounding environment (i.e. in door antennas, exterior antennas near metal surfaces, etc.) and how it influences the over all antenna length. Applied applicable mathematical formulas to prove the influence of stray capacitance. We used the formulas for troubleshooting by calculating present resonate frequency versus the required frequency and determining required length adjustments
  •  Conducted on the air training on what techniques to be used for running and managing a pile-up and how to be ready in advance to use the split function for transmit and receive
  •  Discussed and developed a strategy for installing a Wireless Security Camera System for the school as a student project
  •  Talked about competitive benchmarking for the school and establishing an incubator program for technology advancement
  •  Worked with the students to prepare and put on-line the www.ET3AA.com website. The domain name was purchased for five years, a host site was selected and paid for two years and the new website was uploaded using FTP software.
  •  The students received a nice club financial donation to advance their upcoming projects.

 I must admit, it was a lot of fun for all and we accomplished a lot in three days.
