Monday NOVEMBER 22, 4PM on ZOOM. Email Rich Combs at richsfpd@gmail.com for link. Residents of Tuolumne County interested in Fire Safety and Emergency Communications are invited to an online presentation by Alan Thompson, Satellite Internet Field Engineer of El Dorado Networks of Placerville. Alan helped restore Internet service at several downed cell-phone towers in Paradise shortly after the Camp Fire. What he saw there and learned later about the colossal emergency communications failures during the fire, turned him into an “Accidental Advocate” for fire safety […]

VIEW INSTRUCTIONS HERE TCARES MEMBERS REGISTER HERE Amateur Radio Emergency Service Transitioning to New Online Reporting System The Amateur Radio Emergency Service (ARES) will phase out the traditional ARES report forms later this year in favor of an online system called ARES Connect, a volunteer management, communications, and reporting system. The new system will allow information to be logged by ARES members and managed through the Field Organization. The advent of ARES Connect was among other highlights in “The Amateur Radio Emergency Service (ARES) 2017 Annual Report,” […]

A request went out to the club for 2 or 3 hams to assist. N4NED, KM6NCU and WA6N volunteers to work the Old Priest Grade from 6 am to 9 am. The CHP closed the road and were stationed at the top and bottom of the grade. We set up three stations […]

They call themselves hams and ham radio operators and amateur radio operators, and they are in downtown Sonora and up in Mi-Wuk and Sugarpine and over in […]
Segments of the course entered Yosemite Park TCARES had the privilege of providing radio communications for the Route Marshalls during the 2019 Groveland Grind Adventure Ride for Mountain Bikers. Cyclists enjoyed a course of over 40 miles of terrain between 3400 and 5500 elevation. A team of 15 ham radio operators provided professional tracking and communications for the 60+ participants during a 7 hour period Saturday May 18th, 2019. TCARES deployed a temporary Cross Band repeater (see photos below) at a local peak with […]
We had a GREAT Workshop! On Saturday, April 27, TCARES members presented a workshop oriented toward new and potential Amateur Radio Operators (Hams) and to the general public who might not have a good understanding of what Ham Radio is all about. The workshop commenced at 0900 hours and ended about 1500 hours with topics including what to expect as you study for your FCC license exam, practice exams, demonstration stations, and mingling with current Hams of all stripes. For the first ever workshop […]
TCARES & ARES I am pleased to announce that we will have a very special guest at the TCARES Membership Breakfast Meeting on May 11, 2019. Dan Sohn, Assistant Section Emergency Coordinator, (and perhaps others) representing the San Joaquin Section of the American Radio Relay League (ARRL) (Tuolumne County is in this Section) will be here to talk about ARRL, ARES (Amateur Radio Emergency Services) and the San Joaquin Section. There have been significant changes at ARRL / ARES in the last few months […]
There was recent documentary called “Mega quake 10.0.” With my apologies to the seismologists here is a little comparison to our more familiar dB scale measurements. In some respects we all live in Earthquake Country not just California. The program described the effects of an earthquake in various magnitudes. Some of the bigger quakes have occurred in the middle of the country such as the “New Madrid Quakes” around 1809 and 1810. They rang church bells in Boston! The presenter tried to explain the […]
I have only been a licensed ham operator since August 23, 2011, so most of the history of the hobby comes from what I hear from other hams who have been in the hobby longer than I have. But I have been in the emergency services as a fire fighter and medic for 38 years. I have observed the evolution of the emergency services in America generally and in California specifically over that time. My observations have lead me to think that perhaps The […]

By Jim, N6TP The recent interest in WLW (500 Kw in the 1930s) reminded me of the technology that went into producing a good quality high level plate modulated transmitted signal. You may remember prior to rule change of 30 years or so by the FCC that the maximum power limit (where licensed) was 1,000 watts input. This meant that if you were running high level plate modulation, you had to have 500 watts of RMS audio power for 100% modulation. You will recall […]
Decibels: Pesky Little Critters In our telecommunication careers, we may have all used dBs in our work. Here is a little background and how we use them in amateur radio. Decibels are a form of mathematical shorthand using logarithms. Logarithms probably originated with the ancient Greeks. Logarithms have the property expressing large values or ratios in more easily understood human terms. Decibels originated when the engineering of analog telephone circuit became more complicated. The Bell System of fond memory in the 1920’s needed a way […]
By Jim, N6TP, n6tp@arrl.net We are familiar with the formula for a half-wave dipole. It appears in the antenna handbooks and in various test questions for amateur radio license exams. It goes like this. Divide the operating frequency in MHz into “468” and the answer comes out in feet. For example: 468 divided by 7.150 MHz equals 65.5 feet! If we do a little rounding, we will cut our half-wave dipole to 65 feet 4 inches. Let’s look a half-wave dipole. As the name implies it is […]
