Pavana dam:

The Pavana dam, constructed in 1972 on Pavana River. The Pavana River is a notable river crossing the cities of Pimpri-Chinchwad and Pune in the Indian state of Maharashtra. The river originates south of Lonavala from the Western Ghats, and flows a total of nearly 60 kilometres (37 mi) to meet the Mula river in Pune.

After completing the assembly of 10 meter yagi antenna, team started putting up 20, 40 meter and 2 meter 5/8 antenna. We have used antenna analyzer model number MFJ-259 B. Team MARI using this expensive instrument for their R&D on homebrewing different types of antennas.

The Pune Hams joined team MARI on the second day ie.on 25th January 2015 for the field trip. Soon after breakfast on the second day the participants got down to work. OM VU2ASH/ Ashok Joshi conducted a workshop on optimum utilisation of RF power by tuning the antenna. He made the participants fine tune using of an already installed dipole antenna and brought the swr to 1:1 which was followed by an interactive session on antennas. He also demonstrated an all band loop antenna for qrp use using a gang / variable capacitor and a slimjim made out of a TV ribon line. In addition he explained the construction of a  hex beam antenna and tuned of a 2 m 5/8 antenna to an swr 1:1. VU2ASH also displayed the homebrewed multiband BITEX TRANSRECEIVER with a homebrewed 20W RF amp incorporated onto it.
