ham radio news

Optimism About FCC Enforcement ARRL General Counsel Chris Imlay, W3KD, told the League’s Executive Committee in March that he feels the FCC may provide more effective enforcement on the ham bands in the future. Imlay said the Commission’s new chairman, Ajit Pai, is very interested in improved enforcement and that Michael Carowitz, the new Chief of the Enforcement Bureau, is said to be “amateur friendly.” According to the ARRL Letter, Imlay told the committee he “foresees a potential window of opportunity for improved spectrum enforcement work, as well as the opportunity to build a stronger working relationship with the FCC on all issues.” In a related matter, the Letter reports that the ARRL has begun working on final language of a revised memorandum of understanding with the FCC on its Amateur Auxiliary…

zero bias – a cq editorial

One of my greatest pleasures in this job is the occasional opportunity to talk ham radio with young people. Most recently, I was invited by my friend Bob Hopkins, WB2UDC, to join him in talking about ham radio at Cooper Union (where he’s a professor) to a group of future engineers. Several of them are already hams and if our talk helps to generate more interest among the others, it will be that group of ham students who help usher in their peers to amateur radio. I’m also working a little bit (and hope to do more) with the radio club at the New Jersey Institute of Technology, where another friend — Nathaniel Frissell, W2NAF, whom I’ve known since he was newly licensed at age 15 — is a post-doctoral researcher…

linda ross hufft, sk

The ham radio industry recently lost another of its very special people. Linda Ross Hufft, President of Optoelectronics, passed away on March 26, 2017. Linda was 73 years old. After co-founding the company in 1974, she became president and sole owner in 1990, continuing to run it very successfully until her death. Linda was unique in many ways in the ham radio industry, not the least of which was that she was a woman, and a single one at that. While many women played many vital roles in the male-dominated industry, and continue to do so, few could claim the title of president or founder. Putting in 80-hour work weeks year after year, Linda drove Optoelectronics to grow from a small specialty company to become a powerhouse in the digital frequency…

k9 qrp: fun with ruff radio

Life and work keep me busy, so I never seem to spend as much time with my radios as I’d like. Every once in a while, though, I find myself with a spare moment and a wellintentioned plan to get reacquainted with my Morse key. On one such occasion, I’d just turned on the set and was sweeping through the 20-meter band when I became aware of that peculiar sensation one gets when they’re being stared at. I ignored it until the feeling was punctuated by a loud and impatient sigh. I turned and found Rudy, my German shepherd, standing in the doorway behind me. “What are we doing in here?” he demanded. “It’s a beautiful day! Let’s go outside and have some fun!” Now I’m no lunatic, but any dog owner…

the k9-qrp 4-band inverted v antenna

The HF antenna used as part of my prototype K9-QRP HF station is certainly not a fusion reactor. It’s a very simple affair, but there are details of its construction that are worth sharing. Please reference the assembly diagram in Figure 1. Normally, the legs of a simple dipole antenna are cut to a length equal to one-quarter the wavelength of the desired operating frequency. Since my transceiver is capable of operating on four bands, I designed the antenna to allow for adjustment of the radiators according to the desired band of operation. Each leg of the dipole has been cut into segments, separated by insulators. Each segment is terminated with a (stackable) banana plug. By altering which segments are connected and which are left disconnected, it’s possible to operate on 15,…
