Huh? / We must not assume... (spy etc)
« on: October 19, 2014, 0020 UTC »
For some reason I don't understand why folks think that spy transmissions must be out side of an amateur band...

Think about it... if you wanted to 'hide' a transmission' say in CW... where would be the best place to hide it....?

CW is, let's face it, old tech, so if you wanted to 'hide' it what better place than in an amateur radio band.?

As I said on another board... if you want to hide a tree... hide it in the forest...

That doesn't take a hell of a lot of logic to understand... or maybe I am so far twisted that I don't get it...

But... I think I have it right....  even SSB can be 'hidden' within an amateur band so it wouldn't bring much attention...

If any of you folks think I am wrong then please sound your voices loud and let me know...

But understand, how many of you/us/me/etc know languages to the point where we can be sure.  I have heard so many different languages using "K" or "W" or "A" callsigns that are using different languages who/whom can be sure?

Understand I am NOT trying to invoke paranoia but just saying...  do You Know For Sure?

Please give me feedback...  Don't let me sound off without an amount of rebuttal... Let me hear your ideas on this.

Respectfully yours,

V. G. Werber KA1IIC/8

Huh? / Want to get high?
« on: October 05, 2014, 2055 UTC »
So you want to get high ehhh?

Well here you go:

First get LSD (Large Silicon Diode)

Clip one lead to one ear and the other to the other ear...

Stand beside a broadcast transmitting tower of 50,000 watts or greater...

Sounds a lot like CB so it might be a modified CB rig.  Coversation is very fast back and forth.

Just a note, the 10 meter band has been open for over a week now. Yesterday there were many S9 signals coming in from Europe. I am hoping that this will continue through he winter but alas we all know better <sigh>

While looking for so info on audio apps I ran across this site that seems to have a small but good collection of a number of different projects and DOS programs... these may be of interest to some folks of the group so I am passing this along. The web addy is:

http://www.qsl.net/dl4yhf/

The DOS programs are as follows:

    Spectrum Lab - a tool for audio analysis, DSP, beacon logging, etc.
    WOLF GUI - a graphic user interface for Stewart Nelson's WOLF (Weak-signal Operation on Low Frequency)
    Sound-Utilities - read from the soundcard's ADC and send to DAC
    Audio I/O library - exchange audio in real time between different applications (also for audio streaming using winamp / oddcast)
    CalcEd - a text editor which calculates with complex numbers !
    CurveEdit - a primitive, graphical viewer / editor for array data ("curves")
    PIC programmer - DL4YHF's WinPic for Win95+98+XP, uses LPT or COM1..4, and supports a variety of PIC microcontrollers.
    RDF Calculator: for radio-direction finding, topographic map display, GPS track display, etc

There are a number of other things including one that has caught my interest is his QRP Indoor Loop that uses a standard tuning capacitor instead of a 'butterfly' cap.

I hope this might be of interest to the group.

2014-09-12 01:15 UTC  The First CME Has Arrived

The first of the two CMEs predicted to arrive today made its appearance right on time. G1 ((Minor) geomagnetic storming is expected to begin within the next few hours with a maximum projected level of G2 (Moderate) storms for September 12th. A G3 (Strong) Geomagnetic Storm Watch is still in effect for September 13th due to the combined influence of this CME and the one projected to arrive late on the 12th. G1 (Minor) storming is likely to continue into September 14th. In addition, the S1 (Minor) solar radiation storm that is in progress as a result of the eruption on September 10th is expected to persist for the next few days with a possible slight increase with the arrival of the CMEs. Keep in mind that the forecast periods listed are in Universal Time so aurora watchers in the northern U.S. should be looking for possible activity tonight through Saturday night. Stay tuned for updates.

2014-09-11 05:01 UTC  A Pair of CMEs

G2 (Moderate) geomagnetic storms remain in the forecast for September 12th as a result of the coronal mass ejection (CME) associated with the R1 (Minor) solar flare observed on the 9th. The latest WSA-Enlil model run has the CME associated with yesterday's R3 (Strong) solar flare arriving mid to late day on that same day. A G3 (Strong) Geomagnetic Storm Watch has been issued for September 13th due to the combined influence of these two events with G1 (Minor) storming anticipated to continue into September 14th. In addition, the S1 (Minor) solar radiation storm that is in progress as a result of the eruption yesterday is expected to persist for the next few days. Keep in mind that the forecast periods listed are in Universal Time so aurora watchers in the northern U.S. should be looking for possible activity both Thursday and Friday nights. Stay tuned for updates.

2014-09-10 23:18 UTC  Recent R3 Solar Flare

Active Region 2158, now near center disk, produced a X1 (NOAA Scale R3 - Strong) solar flare today at 10/1745 UTC (Sep 10th at 01:45pm EDT). Impacts to HF radio communications on the daylight side of Earth lasted for a little more than an hour.

Initial information suggests that CME is likely associated with this event, however, further analysis is underway at this time.

Standby for more details.

AM radio, the scratchy medium that long ago aired Franklin Delano Roosevelt's fireside chats, soap operas and the day's most popular music, is trying to avoid becoming static.

Across the country, stations are vying to hold on to listeners as AM radio's audience slowly dwindles. The persistent technology, long dwarfed by FM, has weathered more recent threats including satellite and Internet radio. It is also contending with a new assault from smartphones.

How long before AM radio disappears, if ever, is anybody's guess. But analysts say the fight for relevance is playing out in Los Angeles, the nation's largest radio market by revenue. And KFWB-AM (980), a station founded by movie studio mogul Sam Warner back before the golden age of radio, might be in the thick of it.

After 46 years of presenting news and talk, the veteran station of the AM dial is switching to an all-sports format to rev up its paltry ratings. The change comes after years of erosion for an institution that once was one of L.A.'s top outlets, from the early days of rock 'n' roll, when KFWB was known as "Color Radio," to the years when it had news bureaus throughout California.

"This was one of the crowning jewels of news radio for four decades," said longtime newscaster Phil Hulett, who hosted his last show for the station in late August at the Ports O'Call Waterfront Dining restaurant in San Pedro.

KFWB has been particularly hard hit as listeners have abandoned AM radio at a steady rate.

The station drew 172,000 listeners a week in July, a small sum considering that it broadcasts to a region that has millions of potential listeners. Top-rated music station KBIG-FM (104.3) pulled in nearly 3.5 million during the same time frame.

KFWB ranked No. 54 in the Nielsen ratings for Los Angeles, about 10 slots from the bottom. To be sure, some AM stations continue to post strong numbers, such as the Los Angeles Clear Channel talker KFI-AM (640) and CBS Radio's all-news stalwart KNX-AM (1070). But nationwide, the audiences are thinning out.

The tide began to turn against AM radio in 1978, when the stations accounted for more than half of the radio listening hours in the U.S. Last year its share of the national radio audience was 11.5%.

As recently as 1990, AM radio accounted for about 45% of stations licensed with the Federal Communications Commission. Now FM counts roughly 10,700 outlets, more than doubling AM's 4,700.

"Considering all the problems it has, it's amazing AM radio still exists," said Michael Harrison, publisher of Talkers magazine. "It's like the beautiful horses and carriages you see in New York. Sure, they'll keep them around in Central Park, but you're not going to see them on the highway."

Most people listen to AM radio while driving, and the medium is facing an increasingly crowded dashboard. Beyond FM choices, drivers have new options like satellite and Internet radio, and ways to connect their smartphones to their stereos.

Getting up-to-the-minute traffic updates used to be the domain of AM radio coverage. These days, drivers can switch on smartphone apps like Google Maps and Waze.

"There is very little reason to be optimistic about AM radio, though there are some very strong remaining stations," said Larry Rosin, president of Edison Research, who follows the media industry. "AM retooled with talk radio, but even with that, people are listening to it less and less as time marches on."

Some analysts think that AM will eventually leave new car models altogether, in the same way that manufacturers are now less likely to include CD players in vehicles. AM could face even more trouble if music-streaming services including Pandora begin to dabble in talk shows.
 attention when it decided to release its new electric car without AM, because of signal interference from the battery technology. Although the decision stemmed from the technical difficulty, it still prompted the head of the National Assn. of Broadcasters to write a letter to the car company encouraging it to put AM back into the vehicle.

"It doesn't look good for AM radio," Ron Montoya of Edmunds said. "If people aren't using it, I can easily see manufacturers taking it out and using that space for more smartphone friendly features."

But the radio industry is responding to the changes to keep AM alive.

Some AM stations have started using FM translators so that people can listen to the same content with better reception. In addition, the industry and its regulators see hope in a technology called HD Radio, which lets stations transmit digital signals along with the analog variety. The broadcast industry is even testing a possible move to all-digital AM radio.

Analysts and executives still think that the AM dial has a chance to hold on to its share of ears, especially in Los Angeles, where people spend a lot of time in their cars.

Thom Callahan, president of the Southern California Broadcasters Assn. and one of AM's defenders, noted that 3.47 million people in the Los Angeles area listen to AM radio stations every week, down just 300,000 from six years ago.

Callahan also noted that, despite the doomsaying, AM has also found new life among ethnic communities, including Latinos and Asian Americans. Los Angeles' multiple radio homes for Spanish language audio include KTNQ-AM (1020), KHJ-AM (930) and KLTX-AM (1390).

KFWB, already the radio home of the L.A. Clippers, is betting its future on ballgames and personalities.

In the weeks since it told staff about the coming changes, KFWB has brought on a new programming director and announced the return of sharp-tongued sportscaster Jim Rome to the Los Angeles airwaves. Although the official relaunch is still set for later in September, the station has already filled the gaps with CBS Sports Radio broadcasts.

KFWB's all-sports bid faces serious challenges. Los Angeles already had three AM sports stations, including Clear Channel's KLAC-AM (570) and ESPN's KSPN-AM (710), both of which trounced KFWB's news-talk lineup. The third is KLAA-AM (830), which covers the Los Angeles Angels.

But KFWB head Diane Sutter says the station will be able to carve out its own piece of the market where there are more sports teams than in most cities.

"It means that there's a lot of sports to cover and there are great sports stories every single day," Sutter said.

It's a major switch from the days when KFWB and KNX battled for the news radio ratings crown in Los Angeles, even when the two shared CBS as their parent company. Since 2011, KFWB has been run by an independent trust, which is looking to sell the station.

KFWB has changed its format multiple times over the years since its launch in 1925. It ran with a top-40 rock music format until it switched to all-news in 1968. Whereas KNX was known for its broad-based coverage, KFWB took a more staccato, headline news-style approach.

In 2009, KFWB began adding talk shows, banking on the provocative personality Dr. Laura Schlessinger, while KNX stuck to all-news. But the new approach backfired in 2010 when she used a racial slur 11 times during a broadcast. She departed her syndicated show by year's end.

"They were a very robust station," said Don Barrett, a longtime authority on the local radio business who runs the website LARadio.com. "If there was an earthquake or a fire, you'd go to KFWB."

Hulett, who had manned the microphone at KFWB since 1998, noted that AM has survived the decades-long onslaught from television and Internet outlets. He said all it takes is a new, innovative personality or type of show to add 10 to 20 years to AM's life span.

"We're in the middle of a huge vacuum right now," he said. "It's only a matter of time before somebody comes up with something unique and, like lemmings, all the programming directors copy it."

Until he returns to the airwaves, Hulett will try to reach listeners through a decidedly more 21st century portal his podcast "Phil Hulett and Friends."
