Operating as FY/F5UII, Christian F5UII conducted a DXpedition to French Guiana (FY) from January 13 to 30, 2013. The primary operation utilized the FY5KE radio club station in Kourou, with activity focused on voice modes during specific weekday hours. The resource details the operator's intent to transmit before 12:00z and after 22:00z, or as availability permitted, from the mainland. A significant aspect of this operation involved a dedicated weekend activation of the Salut Islands, specifically **IOTA SA-020**, from January 19-20, 2013. This segment of the DXpedition was conducted from Royal Island (Ile Royale), part of a group including Devil's Island (Ile du Diable) and St. Joseph Island (Ile Saint Joseph), located 14 km offshore from Kourou. The station setup for the IOTA activation included 100 Watts of power, a GPA-030 vertical antenna for 10m, 15m, and 20m, and dipole antennas for 17m and 40m, with antenna deployment contingent on site conditions and propagation. The operator anticipated strong interest for the SA-020 entity. -

Off Grid Ham discusses the benefits of mobile ham radio operation in addition to fixed or semi-fixed base stations. The article highlights the challenges of antenna placement on vehicles, emphasizing the importance of a good ground plane for optimal performance. Tradeoffs between performance and appearance are inevitable, especially with modern vehicles that have plastic body panels. Bonding the coax shield to the car frame is often necessary to establish a good ground plane. Mobile ham radio operation is a valuable option that fills in the gaps left by fixed stations, offering flexibility and convenience for hams on the go. -
