CB Radio

About Us

   Dan here, I began my study of electronics in the late 1970's, inspired by the stereo equipment of the era and the launch of 40 channel CB radios around 1976.  I studied via mail order through CIE or rather the Cleveland Institute of Electronics, as well as the Lafayette School of Radio (now deceased)  and attended Ivy Tech College's electronics courses, as well continued to study intensively through such publications as Bill Orr's Radio Handbook as well as the ARRL Radio Handbook and their various publications.  Needless to say I was also a ham radio operator back in the day.  Altogether my study of radio electronics spanned nearly 10 years of my life.  There is always something new in the realm of radio to learn.  The latest thing I have learned in these past years is Software Defined Radio (SDR) and now I am into that, and have plans to combine it with my CB radios I use here.  SDR is a new frontier for CB as well as amateur radio, it is well on its way in the ham bands now where it has been in use for some years.  ~ I myself obtained a SDR radio back in 2009 straight from Italy.  At that time it was expensive, however today I can obtain such radios for CB users for around $70.

  My initial training in radio included building a Heathkit HW 5400 all band digital ham radio as well as Heathkit test equipment.  In those days we still had Robin, Royce, as well as Siltronix CB radios around to work on, including the Realistic Navajo and of course the Cobra line of radios.  My technician experience included work on various shortwave receivers and so I am familiar also with Hammarlund and Hallicrafters radios and today I use a Grundig Satallit 750 here at the shop.  (I also do some circuit design for SDR radio hardware for my personal hobby interest.)

  My first radio that I liked working on in those days was the Cobra 148 and its companion the Cobra 2000 which was merely the base version of the 148.  Today I like the Galaxy radios which are more like the Cobra 148 and 2000 on steroids, especially the approach to the circuit design of the AM modulation section.

  These days my interest is  not in radio repair but in doing custom work on new radios to upgrade their performance.  And the best way to do this is to start with a really good radio, the best in fact, and proceed to upgrade their audio sections, as well as tweak the modulation circuits, open the SSB clarifiers, and add the typical extras that most CB'ers want.  Also some things that are not usually provided in terms of CB shop modifications include changing the receiver sections ceramic filters for cleaner AM reception. ~ I have to say however that Galaxy radios use a +/- 4.5 kHz ceramic filter and so this actually is ideal for CB, and hence leave them as they are.

  CB radio is just as every bit interesting as amateur radio, and just as fun.  Sometimes its a challenge to us all, as we all try to upgrade to better equipment and antennas.  And this is not much different than amateur radio.  Now the next thing in the world of CB is to upgrade the technical specifications for the purity and bandwidth of our signals, however Galaxy radios have given us a head start in that direction, and are the best radio for the money.
