RAN Technology

About RAN Technology


    It all began....

       In my 2nd grade classroom, where the teacher, Mrs. Jeffers, provided something besides the usual puzzles and games for spare-time play.   There were wires, light bulbs in porcelain sockets, knife switches, motors, buzzers, tools...and #6 dry cell batteries.   Several of the boys and I couldn't finish our work fast enough and would have gladly skipped recess to be able to wire up new contraptions that often didn't work, but fascinated us nonetheless....

 

My name is Bob (Robert) Nickels and by the time I'd moved into junior high, I'd graduated to a different kind of bulb - the vacuum tubes that made radio possible.  I'll tell more of my story on the blog here, but suffice it to say I'm a lifelong radio and electronics nut and what started in Mrs. Jeffers classroom has provided me with endless challenges, opportunities, and a career in the electronics industry, (I am now retired from Honeywell), and have the time and ability to indulge myself in my hobby full-time.   I've been a licensed amateur radio operator since age 15, hold an Amateur Extra class license (W9RAN) and have been active on many bands and modes over the years.  But no matter where I've lived or what's been going on in my life, I've never lost the fascination with making things, fixing them when they don't work, and playing radio.

This site reflects my wide-ranging interests and perspectives, from historian to author, experimenter, and developer of my own products  under my business and technology consulting umbrella,  RAN Technology Inc.   It will be an eclectic mix but I'll try to make it worth your time to hang around and see what's new, because I know I will run out of time long before I ever run out of projects and ideas that I want to pursue.   And there comes a time when it's time to share the knowledge, experience, and toys that have been acquired with others.
 

Pull up a chair...

73, Bob W9RAN

The Pioneer 530

made by JAARS for Wycliffe Bible Translators In 1917 a missionary named William Cameron Townsend went to Guatemala to sell Spanish Bibles. But he was shocked when many people couldn’t understand the books. They spoke Cakchiquel, a language without a Bible.   He believed everyone should understand the Bible, so he started a linguistics school (the Summer Institute of Linguistics, known today as SIL) that trained people to do Bible ...  READ MORE

Robert and Richard Santin - true ham heroes

KØVTD and KØULQ (SK) When I was first licensed in the 1960s in Nebraska, two groups of hams were commonly heard on the air before those with jobs got off work - other teens like me and the disabled hams.   Some of my earliest Novice ham buddies were blind students at the Nebraska School for the Blind in Nebraska City, and there were many other visually-impaired hams, all of whom were exceptional operators, e...  READ MORE

Ceramic Loading Capacitor Replacement

32V series, Vikings, etc Old style mica capacitors were used in the pi-net matching sections of several vintage transmitters and the combination of age, heat, and high RF currents have made them likely failure items.   My Collins 32V-2 transmitter was to the point where it would not properly load to full power on 75 meters so something had to be done.   Mica capacitors are no longer made but fortunately new...  READ MORE

Universal Frequency Converter

Modify as needed I found myself wanting to convert various frequencies to other frequencies and wanted a cheap and easy solution, so I designed a simple "universal converter" using the NE-602 and a programmable oscillator from Epson.  I'd used the same combination in hundreds of "RANVerter" SDR Upconverter projects since my Dec. 2013 QST article and knew that while there were limitatio...  READ MORE
