It all began with one man…Frank Dawson Bliley. In 1930, one year into the greatest economic collapse our country has ever experienced, the young engineer was struggling to find steady work.
Bliley Technologies Inc. was originally founded as the Bliley Piezo-Electric Company in 1930. Initially, we manufactured quartz crystals for the amateur radio market. In the mid-1930s, our customers and products soon broadened to match the interests of the burgeoning military and commercial communications fields and our name was changed to Bliley Electric Company. In 1939 we were the largest Crystal Company with 11 employees.
This was an excerpt from the Bliley History from the Bliley website…..
The RG designation stands for Radio Guide; the U designation stands for Universal. The current military standard is MIL-SPEC MIL-C-17. MIL-C-17 numbers, such as “M17/75-RG214”, are given for military cables and manufacturer’s catalog numbers for civilian applications. However, the RG-series designations were so common for generations that they are still used, although critical users should be aware that since the handbook is withdrawn there is no standard to guarantee the electrical and physical characteristics of a cable described as “RG-# type”. The RG designators are mostly used to identify compatible connectors that fit the inner conductor, dielectric, and jacket dimensions of the old RG-series cables.
The Blaw-Knox Company was out of Pittsburgh Pa.. Its Radiator Towers were patented in July of 1930 with the tallest being 1030 ft and is in Hungry. They also built free standing conventional (uniform cross-section) towers. They built more conventional towers than the diamond radiator ones….

The Amateur’s Code
by Paul M. Segal, W9EEA (1928)
The Radio Amateur is:
CONSIDERATE never knowingly operating in such a way as to lessen the pleasure of others.
LOYAL offering loyalty, encouragement and support to other amateurs, local clubs and the American Radio Relay League, through which Amateur Radio in the United States is represented nationally and internationally.
PROGRESSIVE with knowledge abreast of science, a well built and efficient station, and operation beyond reproach.
FRIENDLY with slow and patient operation when requested, friendly advice and counsel to the beginner, kindly assistance, co-operation and consideration for the interests of others. These are the hallmarks of the amateur spirit.
BALANCED Radio is an avocation, never interfering with duties owed to family, job, school or community.
PATRIOTIC with station and skill always ready for service to country and community
LORAN, stands for long range navigation,[a] was a hyperbolic radio navigation system developed in the United States during World War II. It was similar to the UK’s Gee system but operated at lower frequencies in order to provide an improved range up to 1,500 miles (2,400 km) with an accuracy of tens of miles. It was first used for ship convoys crossing the Atlantic Ocean, and then by long-range patrol aircraft, but found its main use on the ships and aircraft operating in the Pacific theater.
The solar cycle or solar magnetic activity cycle is the nearly periodic 11-year change in the Sun’s activity (including changes in the levels of solar radiation and ejection of solar material) and appearance (changes in the number and size of sunspots, flares, and other manifestations).
They have been observed (by changes in the Sun’s appearance and by changes seen on Earth, such as auroras) for centuries.
The changes on the Sun cause effects in space, in the atmosphere, and on Earth’s surface. While it is the dominant variable in solar activity, aperiodic fluctuations also occur. More at Wikipedia
The UCAR Center for Science has a lot of good articles on the sun….
The solar cycle is a 28-year cycle of the Julian calendar with respect to the week. It occurs because leap years occur every 4 years and there are 7 possible days to start a leap year, making a 28-year sequence. More at Wikipedia
