Hamcation 2024

Went to Hamcation 2024 in Orlando with Dave Fulk.

Purchased a 12v 30a power supply.

Ran into Bob B. and Liz K. while there.

Hooked up the Kenwook TM271 by my chair so I can have VHF in the RV.

Hamvention 2023

Was in Ohio only for a week.
Used the car to go from appartment to the fairgrounds.
Only saw the appartment to sleep.

Time to study some more

 The ARRL Extra Class License Manual for Ham Radio is your ticket to every privilege granted to amateur radio operators all frequencies, operating modes, and power levels. It has all the questions and answers, with detailed explanations, for examinations taken between July 1, 2020 and June 30, 2024. To upgrade to Amateur Extra, you must already hold a General class license (or have recently passed all of the exams required for a General license). This guide is all you need to not only pass the exam but understand the material. You'll study small sections at a time: Operating Practices Rules and Regulations Electrical Principles Components and Building Blocks Electronic Circuits Radio Signals and Measurements Radio Modes and Equipment Antennas and Feed Lines Topics in Radio Propagation

Ohm's Law

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: 

                I = V / R

Where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current. If the resistance is not constant, the previous equation cannot be called Ohm's law, but it can still be used as a definition of static/DC resistance. Ohm's law is an empirical relation which accurately describes the conductivity of the vast majority of electrically conductive materials over many orders of magnitude of current. However some materials do not obey Ohm's law, these are called non-ohmic.

The law was named after the German physicist Georg Ohm, who, in a treatise published in 1827, described measurements of applied voltage and current through simple electrical circuits containing various lengths of wire. Ohm explained his experimental results by a slightly more complex equation than the modern form above.

Bike with Ham Radio

Got the antenna and Yaesu FT2dr added to the bike today.

Works really well.
