8 Watts is the new Black

In the fashion world, a trendy fabric, a stylish new cut, an innovative design becomes the next big trend... it becomes the "New Black".
With handheld Ham Radios, it appears 8 watts is currently the New Black, and from all indications, it's quickly establishing a benchmark in performance that defines "the next new thing."

Within recent months a series of handheld radios have entered the market with one defining difference, greater output transmit power. Normally, .5 watts, 1 watt, or 4 watts is the standard output depending on make & manufacturer, a range that pretty much has been a given standard industry wide.
But with Chinese Manufacturer Baofang/Pofung offering hand held radios with twice as much output power, that standard is now, "old fashioned."

Here's a short list of new "Blowtorch" handhelds available...

BaoFeng BF-F8HP

Seems strange. This radio has only been out for 3 months, and it's now the "Grand Old Man" of 8-watt handhelds. Baofeng's BF-F8HP debuted mid August 2014, to rave reviews &  tremendous demand. An upgrade of the UV-5R model, it rolled out new firmware, a new antenna & a great new user manual that actually makes sense. Just recently the BF-F8HP has been upgraded with a new stock heavy duty 2000 mAh Battery.

Baofeng PoFung GT-3TP Mark-III

The earlier GT-3 model's biggest difference from the UV-5R line was it's cosemeticly redesigned two-tone case. But just in time for Christmas it got a new name and 3 new power modes: 1,4 & 8 watts.
offered by "Baofeng Radio US", Houston TX based Foscam Digital Technologies LLC.
The BF-F9 V2+HP is a stock BF-F9 model, with the ti-power upgrade. That & along with more letters & numbers to it's name. Most notable unique selling point? Offering models in Black, Blue, Red, Yellow & Green Camouflage color cases.

Doubling output power to 8 watts essentially adds 2.5 dB. in transmitted signal strength. In practical terms, it makes for a louder signal, offering greater range.  The trade off is greater demand upon the radio's battery. Naturally, more output power means quicker battery drain, so it should be noted, only the BF-F8HP is currently offered with a larger capacity battery as stock. (In time, that too will change).

Maybe someday in style again...

Will 8 watts become the new "Standard" in Handheld Ham Radios? A closet full of Neru Jackets is betting on seeing more powerful handheld radios being offered by other manufacturers in time. 8 watts of output power is fashionable for the moment. As fashion statements go, it is indeed a powerful one.

Getting the Word Out by the Numbers

Scattered across the shortwave radio bands, often on the fringe of broadcast portions of AM shortwave, or Amateur Radio allocated frequencies, are mysterious signals... mostly repeating music tones with a spoken string of disjointed numbers... they are covert spy "Numbers" stations.  It is the surest method to send coded messages to deep cover operatives in the field, without risking compromise of both the message, and who is receiving the message.
The mysterious "John has a long mustache... the chair is against the wall" types of numbers & tones isn't just a Hollywood plot device, they're how Intelligence Agencies instruct their deep cover field agents covertly.  Despite all the technological advancements in internet, computers and smartphones, nothing offers a safer, & completely unbreakable method of communication.
You can hear these stations yourself, you just need a shortwave radio receiver to tune in the frequencies these signals are broadcast. Enthusiasts in the Shortwave listening (SWL) hobby often post frequencies & times they've encountered a "numbers" station, it's a hobby of sorts to seek out these signals. The fact of these signals being publicized doesn't diminish their effectiveness at all. Websites like The Global Frequency Database, are akin to a White Pages directory, for some of the signals you may encounter.

The importance of radio hasn't diminished one bit, despite all the advances in technology. It's proven everyday by these ghostly signals, showing they are not a relic of the past, but still a vital part of intelligence today.

How well are you Prepared?
Do you have a good portable Shortwave Radio? There's a wide selection of portable shortwave radios available today, most able to monitor police, fire, & rescue, as well as the worldwide radio broadcast bands. Some able to be powered with a hand crank or solar power and can even charge other devices. It's always a smart idea to have one handy, just in case. How knows? Maybe hearing "Mary had a little Lamb" may mean more than just a nursery rhyme.

MADISON COUNTY, Tenn. -- Life in the digital age is filled with the World Wide Web, which is why some first responders wanted to re-wire their ham radio skills Friday.

In order to continue communicating if the Internet fell victim to a mass cyber attack, agencies from across Tennessee would turn to radio.

"We can actually send email and attachments, video and what-not via ham radio without ever using Internet," said Mike Winslow, risk manager for Madison County. READ MORE

Wide Range Receive Radio via SDR & Android

So much technology is changing the face of radio. A new type of "sound card"... this one processing RF frequencies instead of sound waves, has opened up the realm of low-cost radio receivers with virtually limitless potential to explore the electromagnetic spectrum.
Software Defined Radio, SDR, center around a specific processor chip... RTL2832, initially used to tune HDTV broadcast TV on desktops & laptops. But it wasn't too long before some imaginative types figured out that it can tune a lot more than the narrow part of the spectrum carved out for HDTV. Now it's like every day there's new apps, new circuits, and new things being done with a SDR dongle and some software.
The hardware being explored here is just a tiny example of what can be utilized. Matching up a Proscan Android 7" Tablet, to a UHF/VHF/HF RTL-SDR Tuner Receiver to receive FM Radio is a snap, but that's just the tip of the iceberg. It's not just local Broadcast stations, the set-up potentially can tune in ANYTHING in the UHF & VHF part of the radio spectrum. Adding a tuned antenna other than the one that comes stock, tuned for Broadcast FM, you'll have a capable portable receiver for a huge part of the radio spectrum.  Being that it's done on a portable Android Tablet demonstrates practicality & portability in spades.
SDR Shopping? Check these out...
UPDATE: The Software Defined Radio hobby is brand new territory. Practically each day, enthusiasts  are exploring new ways to utilize the hardware, creating new software, and coming up with new applications. No license is required to operate a radio receiver, so anyone can get into the hobby. And if you are inclined to "roll your own" and build your own electronic circuits, there's plenty of SDR kits, plans & schematics available to tinker with.

RF Analyzer: brand new App for SDR's driven by Android like the Hack RF One

One of best places to learn more about SDR's is RTL.SDR.com a continually updated clearinghouse of everything SDR. From there you can unleash your inner geek learning about cutting edge SDR circuits, test new apps and software plug-ins that unleash more features and new applications.

Education in Radio Theory Courtesy of the US Army

Anybody can be a Ham nowadays, the basic licensing isn't too hard to figure out, but if you're serious about the hobby, and serious about radios, it's important to learn how the Radio works. That's also the opinion of the US Army in training troops to operate & repair radios. The Army's been training troops fresh out of basic training to become Radio Specialists & Operators for decades. The training starts with the fundamentals of basic radio theory, and we can make use of the same training movies the troops had to view, for Ham Radio. While the films are a bit dated, the theory isn't. They offer valuable insight to the fundamentals of radio, especially in explaining that which is such a mystery to many.

Here's is what you learned about FM Radio Theory if you were in a Army Ground Radio School back in 1964:

A Portable HF Antenna as Adaptable as a Chameleon

The focus on communications under field conditions often involve UHF/VHF handheld radios, good for tactical point to point close contact. But to reach over the horizon, an HF Radio is the meat & potatoes for that communication task.
Modern ham radio boasts HF gear fitting in a backpack with globe spanning reach, however when the rubber meets the road, it's the antenna that far often makes the difference in making the radio do it's thing.
This is where Chameleon Antennas comes in. The Newport Beach based manufacturer has hit great strides in offering top quality, highly efficient and highly configurable field antenna systems perfect for emergency, space restrictive, and stealth operations.

Chameleon Antennas newest, the CHA HYBRID-MICRO is all that in spades.


The CHA HYBRID-MICRO is a lightweight highly portable broadband antenna system, designed to offer maximum portability and performance. The antenna weights about 1 lb. The antenna will operate at all frequencies in the 1.8-54 MHz band without any adjustment with most modern external antenna tuners. No masts or guying are required. The antenna will work successfully supported by trees, masts, the tops of vehicles or any convenient object or structure. The antenna works most effectively when elevated at a reasonable height. Like it's lizard namesake, the Chameleon, the antenna can be configured to adapt to it's surroundings.
The number of different antenna configurations is impressive!
To operate on the High Frequency Amateur Radio Bands, you must be licensed with a higher than Technician Class license. However it is easy to learn enough radio theory to pass. It is no longer a requirement to know morse code to get licensed, and armed with a General Class Ham License, you can be granted permission to operate on 90% of the world-wide HF bands.
With only a 12 volt battery, a low-power HF portable radio, and a wire antenna like the Chameleon CHA Hybrid-Micro, you can easily make contact over the horizon, beyond a disaster area, or around the world.

Weathering the (Solar) Storm

DUCK!
Those of you working HF are obviously looking for something to do. Band conditions are lousy for the moment as the sun has blasted some charged particles our way, rendering HF propagation into so much hash & static. Oh well...
Goes to show... unless you're a Ham Operator, or read stuff on the internet, you'd more likely never know that the planet is awash in a direct stream of solar flux. But by breathless accounts from the popular press, we should all be hanging on for dear life as the sun has sent a tremendous cloud of plasma our way. Funny... can't tell it from looking outside that's for sure.
So while waiting for the MUF (Maximum Usable Frequency) to get back to normal here's a look back at some of the most noteworthy solar storms Earth has had to deal with since... when someone started following such things... (Article courtesy of Space.com)
1859: The Carrington Event
The Carrington Event of 1859 was the first documented event of a solar flare impacting Earth. The event occurred at 11:18 a.m. EDT on Sept. 1 and is named after Richard Carrington, the solar astronomer who witnessed the event through his private observatory telescope and sketched the sun's sunspots at the time. The flare was the largest documented solar storm in the last 500 years, NASA scientists have said.
According to NOAA, the Carrington solar storm event sparked major aurora displays that were visible as far south as the Caribbean. It also caused severe interruptions in global telegraph communications, even shocking some telegraph operators and sparking fires when discharges from the lines ignited telegraph paper, according to a NASA description.
