Today the club got together to field test their home-brew antennas, battery packs, coffee making abilities in preparation for Portable Ops Challenge run by the team at Fox Mike Hotel. 

Frank EI8HIB has fine tuned his dipole for 20m.

Rebuilding a Clansman 1Ah 24 Volt Battery

-

By  Michael Kennedy (EI6IRB) The objective was to undertake a basic rebuild of a 1Ah 24v alkaline Clansman radio battery (NSN 6140-99-620-8058) to allow it to be used on various Clansman radios, particularly the PRC-320 and PRC-351. The battery arrived among the ancillaries with a recently purchased PRC319. It was manufactured in July 1989. Unlikely to charge, let alone hold a charge, the battery was test-charged under constant observation using a standard Clansman 28v battery charger (NSN 6130-99-117-0450). The battery case soon became hand-hot and after ten to fifteen minutes it began leaking battery content which appeared to ‘boil’ and bubble out of the top of the unit. Unsurprisingly, the battery did not hold a charge. As anticipated, it was unserviceable. As the case was in a very good cosmetic condition, there was every chance that the battery could be refitted with a similar voltage and ampere battery and made serviceable again. The first task was to open the unit and remove the

Black Sky Exercise 2023

Introduction On Saturday the 27th of May the members of the East Leinster Amateur Radio Club (ELARC) conducted a Black Sky drill amongst the sunny Wicklow mountains. Some background to the drill. A Black Sky drill is a simulation of a major extended power outage. The power outage can be either man made, such as an electromagnetic pulse, a cyber-attack on the grid or a physical attack on the power distribution network. It can also be caused by a natural phenomenon such as a coronal mass ejection similar to the Carrington event of 1849 which wiped out large sections off the early Telegraph system in the United States. Causing Telegraph stations to burst into flames. Other causes can be winter ice storms, hurricanes, or other major weather events. These black sky events are typically very rare but have a very high impact to the electrical distribution grid. Training Goals This drill is a scripted, Directed Net with some specific training goals: Improve operator message handling skills. Be

Winter Field Day 2023

With portable operations being the main focus area for the East Leinster Amateur Radio Club (ELARC), partaking in the Winter Field Day is not a surprise. We set out to establish a station at the Irish Military Museum & Park . Access to the vast camping area was a factor in our success. Located on the north facing side of a hill outside Collon, just inside the Co Meath border. With good take-off for HF DX to the North, East and West. Our setup consisted of several radio systems in the communication tent. We could operate on 160/80/40/20 metre bands. We used homebrew, dipoles, linked dipoles, EFHW , and Clansman military dipole for the 160m band. 80m and 160m antennas were deployed in NVIS fashion. Where the 40m and 20m were a bit higher relative to the wavelength. Our wires were supported by a 10m telescopic mast, a couple of fishing rods and local vegetation. Radios were a standard HAM issue Yaesu FT-857D and FT-891. In total we were able to operate 4 bands at the same time. We did
