Please note: the W5RRR repeater returned to service on 9/18/18. The JSCARC W5RRR 2m repeater will be off the air to replace the antenna, which was damaged by a lightning strike today at JSC. The top-half of the repeater antenna is missing, and what’s left has been tested to be completely non-functional. We need to … Read more…
Our Saturday T-Hunt. 3 Foxes. 2meters. newbies and experts. A third tricky hidden transmitter. KB5PGY is our best hound. More, please!
AB5SS will kickoff a T-Hunting event for the club on May 12. He’s found a very useful Direction Finder project kit, called the HANDI-Finder, which utilizes a simple CMOS oscillator to continuously switch your Handheld FM radio between two small wire loop antennas made from wire coat hangers. Due to this phase-difference detection scheme, by adding a small handle and turning it, a very sharp positional null can used to help one locate a signal’s direction. It’s a perfect small project for T-Hunting. The current pricing is $27.95 +$6 shipping which is a nice sweet spot for a DIY project.
The club will soon embrace the T-Hunting bug. T-hunting is a term for Transmitter-hunting or “Fox Hunting”. A secret transmitter(s) is/are hidden at an undisclosed location, and participants use their HT or other exotic devices to hunt it down.
Here’s an audio clip of Mike N8MTV’s successful tracking and downlink of the ISS ARISS station NA1SS and KD2IFR, from the W5RRR Satellite Station. This was a scheduled ARISS school contact with the Central Islip Union Free School District, Central Islip, NY on April 18.
The school is described as, ” – Home of the Musketeers and a proud Suffolk County, New York school system, where approximately 8,000 students in grades Pre-Kindergarten through 12 receive their formal education. Our School District’s motto is Children Our Future ~ Diversity Our Strength. The Central Islip Union Free School District is comprised of eight schools: one district-wide early childhood center, four elementary schools, two middle schools and a high school.”
From Mike, N8MTV.
“Enjoy! .. thought this would be great to show to the club. The first image started recording as the ISS was rising, hence the noise at the top of the image. Transmission stopped well in advance of setting over the horizon, so the next two images are decent.
