IC-705 Portable Power

The sun is setting behind the ridge. Your battery just dipped below 12 volts. A pileup is forming on 20 meters, and you have exactly seventeen minutes of daylight left to make the contact that validates your activation.
This is the moment that separates the prepared operator from the frustrated one. The Icom IC-705 has redefined what portable amateur radio can be-all bands, all modes, spectrum display, GPS, Bluetooth, and battery-powered operation in a package that fits in a daypack. But owning the radio is not the same as mastering it.
IC-705 Portable Power is the definitive field guide for operators who refuse to let power limitations, antenna compromises, or weather define their operating envelope. Written for the experienced ham who demands substance over speculation, this book delivers advanced tactics across eight comprehensive domains:

• Power systems that keep you transmitting through multi-day activations-LiFePO4 sizing, solar insolation mathematics, MPPT integration, and emergency fallback strategies when everything else fails.
• Antenna engineering that transforms compromise into capability-EFHW transformer design, linked dipole rapid deployment, magnetic loop remote tuning, and real-world solutions for rocky summits, dense forest, and urban parks.
• SOTA and POTA mastery-from pre-activation route analysis and propagation forecasting to sub-ten-minute deployment workflows and the spotting discipline that turns solitary activations into community events.
• Go-kit construction at three investment tiers, with modular architectures that scale from budget field days to expedition-grade polar deployments.
• Emergency communications-ARES/RACES integration, Winlink field deployment, APRS tactical messaging, and the NIMS framework that transforms volunteer willingness into professional effectiveness.
• Mobile and vehicle operations-alternator capacity analysis, RF exposure compliance, off-road antenna survival, and the rapid-extraction protocols that turn your vehicle into a forward operating base.
• Advanced propagation exploitation-grey-line timing, sporadic-E recognition, meteor scatter operation, and the weak-signal VHF/UHF frontiers of satellite, EME, and beyond.
• The emerging ecosystem-mesh networking, hybrid voice/data architectures, cloud-logging integration, and the portable operations culture that will sustain amateur radio into its next century.
