Can I Use My Ham Radio on Public Safety Frequencies ? by K0NR

Posted by

This is an update to one of my most popular posts on K0NR Web Site 

We have quite a few licensed radio amateurs that are members of public safety agencies, including fire departments, law enforcement agencies and search and rescue. Since they are authorized users of those public safety channels, they often ask this question:

Can I use my VHF/UHF ham radio on the fire, police or SAR channel?

Radio Call Saves SOTA Climber Following Fall

Posted by

fall

A Littleton, Colorado, radio amateur and mountaineer was happy to have his hand-held transceiver along on May 17 after he slipped and fell from an icy ledge in Berthoud Pass while snowshoeing. Summits On The Air (SOTA) enthusiast Brad Byland, WA6MM, said he’s been climbing and mountaineering for many years now and never before came this close to “a possible life-ending disaster.”

“I’m doing fine,” Byland told ARRL this week. “I didn’t get hurt…only bad wind and sunburn on my face! My daughter says my geeky hobby — ham radio — saved me from my dangerous hobby — climbing and mountaineering!”

Byland said that while this was his first climb in the Berthoud Pass area, he was never “lost,” as some media accounts reported. He had prepared to climb Mount Flora — which would have been his 29th SOTA peak — by studying maps and others’ trip reports, plus he had hisiPhone with GPS, a compass, and his radio along.

“[T]hings went smoothly until about 12,700 feet,” Byland said, at which point, with visibility deteriorating, he decided to turn back. “It wasn’t long before I was in a total whiteout,” he recounted. “The ground is white, the air around me is white, and I had no perception of direction and elevation. My iPhone GPS was of no use as I couldn’t read the display. I pulled out my compass for navigation.” Byland said he knew the basic heading he should follow along the ridge, and he proceeded.

Got Grids? ARRL June VHF Contest is June 13- 15

Posted by

grids

Summer is nearly here, and that means it’s time for the ARRL June VHF Contest, June 13-15! Participants in the US and Canada (and their possessions) work stations in as many different 2 × 1° Maidenhead grid squares as possible, using the bands above 50 MHz. Stations outside the US and Canada may only work stations in the US and Canada (and their possessions). Stations in KH0-9, KL7, KP1-KP5, CY9, and CY0 count as W/VE stations and may be worked by DX stations for contest credit.

The June VHF Contest occurs at the start of the summer sporadic E season, and intense openings on 6 meters and even 2 meters are possible. It’s a whole new world of propagationpossibilities that also include tropospheric ducting, aurora, and even meteor scatter and moonbounce. With many HF transceivers on the market equipped for 6 meters and sometimes for other VHF/UHF bands, getting on the air for this event is easier than eve

First Wireless transmission marked with recreation

Posted by

first

LAVERNOCK beach hosted an historical recreation of the first wireless transmission by Guglielmo Marconi which was sent from Flatholm Island to Lavernock point, 118 years ago.

Although the first wireless signal was sent on May 11, it was on May 13 when Wales and England were linked by wireless, from Lavernock to Brean Down in Somerset.

The event on Monday (May 11) used a ‘spark gap’ transmission. Although it is illegal, it was allowed by Ofcom after much discussion as long as it was on low power.

CW — The Original Digital Mode by N9JA

Posted by

morsekey

Hmmm, now that I’ve typed that headline, I’m wondering about some potential earlier digital modes. Things like smoke-signals and drum messages have some of the same characteristics. Even so, I’ll restrict this discussion to radio frequencies and to amateur radio.

One of the things that I like most about our hobby is the extremely wide array of activities available. Plus, you can get involved at whatever level best suits your interest, your available time, or your pocketbook. That includes CW, or Morse Code operation, from low-speed straight-key conversations to high-speed telegraphy competitions. CW has something for everyone.

ORIGINAL DIGITAL MODE

We call it a digital mode as it consists of an essentially binary code of on and off tones. Dits, or dots, are one unit, while dahs, or dashes, are three units in duration. Spaces between letters are three units and the spaces between words are seven units. If only that last one was followed more closely on the air, CW would be a bit easier for beginners to decipher.

For those of you interested in digging much deeper, Wikipedia provides a great deal of information at Morse Code.

China Set to Launch Several Amateur Radio Satellites this Summer

Posted by

cas-3a

CAMSAT has announced that the CAS-3 amateur satellite system is nearing completion, and six Chinese amateur satellites will be launched in mid-July.

“All six satellites are equipped with substantially the same Amateur Radio payloads, a U/V mode linear transponder, a CW telemetry beacon and an AX.25 19.2k/9.6k baud GMSK telemetry downlink,” the CAMSAT announcement said. CAMSAT said that each Amateur Radio complement has the same technical characteristics, but will operate on different 70 centimeter uplink and 2 meter downlink frequencies.

CAMSAT said it has worked closely with DFH Satellite Co Ltd, a Chinese government aerospace contractor, to complete the project. “All the satellites are currently conducting finaltesting and inspection,” CAMSAT added. Four of the satellites are described as “microsatellites,” while three are listed as CubeSats.

CAMSAT said a Long March-6 rocket will carry the satellites into orbit. The launch will take place at Taiyuan Satellite Launch Center. CAS-3A will have sun-synchronous orbits of about 450 km, while the other satellites have sun-synchronous orbits of about 530 km.

29 MHz – The forgotten frequency for amateur radio satellites

Posted by

29

In the early days of satellites, not many years after the launch of Sputnik One in 1965, amateursatellites were designed and launched with downlinks on 29 MHz. Satellites were much larger than the present day CubeSats which only measure 10 x 10 x 10 cm and present interesting challenges for antenna  design and placement.

Universities and other scientific research institutions are using portions of the amateur spectrum for their CubeSat’s which has caused the 145 and 435 MHz amateur-satellite band segments to be very crowded, leading to an increasing number of satellite builders to explore alternatives.  For many, such as those requiring single-channel bandwidth greater than approximately 12,5 kHz, the best answer will be found in the microwave bands.

However, for those who can use it, the International Amateur Radio Union (IARU) satellite frequency coordination process has now opened another alternative: 29 MHz uplinks.

The use of amateur spectrum by universities and scientific research institution for their experiments is not the ideal solution and has only been agreed to by the IARU  for a limited period till alternative spectrum is identified and allocated by the ITU  for this purpose.

Breakthrough in Liquid Metal Antenna

Posted by

liqattn

By: Scott Wilson

In our cable and satellite driven world, few people outside the realm of HAM radio enthusiasts understand much about how antenna theory works. Yet, as our connections become increasingly wireless, antennas are becoming more important than ever.

Radio boffins know that the electrical length of resonant antennas (the most common type ofantenna in use) will provide the greatest efficiency at an odd multiple of one-quarter the wavelength of the frequency in use. Antennas may have a different physical length to account for a variety of electrical factors, but at some level, the size of the antenna will have some rough correspondence to the wavelength at which it performs most efficiently and the pattern around which it radiates.

FCC Eliminates Amateur Radio Vanity Call Sign Regulatory Fee

Posted by

fccc

The FCC is eliminating the regulatory fee to apply for an Amateur Radio vanity call sign. The change will not go into effect, however, until required congressional notice has been given. This will take at least 90 days. As the Commission explained in a Notice of Proposed Rulemaking, Report and Order, and Order (MD Docket 14-92 and others), released May 21, it’s a matter of simple economics.

“The Commission spends more resources on processing the regulatory fees and issuingrefunds than the amount of the regulatory fee payment,” the FCC said. “As our costs now exceed the regulatory fee, we are eliminating this regulatory fee category.” The current vanity call sign regulatory fee is $21.40, the highest in several years. The FCC reported there were 11,500 “payment units” in FY 2014 and estimated that it would collect nearly $246,100.
