Preseus SDR info

I have received a few e-mails inquiring what I know about the Perseus by Microtelecom s.r.l. I do not have any experience with this item nor do I know of anyone who owns one.
What I have read thus far is that the Preseus is a software defined VLF-LF-MF-HF receiver based on an outstanding direct sampling digital architecture.
It features a 14 bit 80 MS/s analog-to-digital converter, a high-performance FPGA-based digital down-converter and a high-speed 480 Mbit/s USB2.0 PC interface.

The best I can do is providing you some links to which you may have already found. I think the yahoo group, (linked below) might be the best place to interact with those who have this interesting SDR Receiver.

Desk Top Mic

My wife and kids asked me what last minute idea I had from my wish list under 200 dollars. Right away, the vision of The Fin came to mind. So, with any luck, I might have a pretty cool stocking stuffer coming my way.

The Fin, exhibiting a remarkable, natural, clear sound and designed especially for live sound, recording and broadcast applications. The exceptional performance is achieved by the use of a special magnet structure with a large 1 1/18" aluminum low mass voice coil assembly similar to the Heil PR 20. The frequency response is 60 Hz - 18kHz with that traditional Heil Sound mid range 'bouquet' at 4kHz, which presents incredible brilliance and presence. The Fin exhibits a tight linear cardioid pattern. The chrome finish is a special 'showchrome' where the steel body is copper plated and then double chrome plated producing a deep chrome finish. A blue molded internal foam windscreen inside the grill covers the large diameter Heil dynamic microphone element mounted in a specially tooled Sorbothane c shock mount.

The fun part of The Fin is the four blue L.E.D. lamps mounted inside. These can only be illuminated when using The Fin into one of the 3 pin balanced XLR inputs of a professional mixing console that supplies a + 48 volt d.c. phantom voltage down the balanced mic line. A small slide switch on the bottom of The Fin must be switched to 'ON'.

Morse Code from Washington DC

This is cool. We have an amateur radio operator in the U.S. House of Representatives. I have often wondered how many amateur radio operators are in elected office.
The really cool thing about Rep. Greg Walden is that he is a very Conservative Republican. I think as US citizens we are fortunate to have him in Washington DC. He is representing the state of Oregon well.

Rep. Greg Walden (R-Ore.) announced Thursday on Twitter that he will chair the House Commerce Committee's Communications subcommittee — using what appears to be Morse code.

The tweet from @repgregwalden: .-- .. .-.. .-.. / -.-. .... .- .. .-. / -.-. --- -- -- / .- -. -.. / - . -.-. .... / ... ..- -... / --... ...-- ... / .-- --... . --.- ..

Using a handy (in some very rare instances) online Morse code translator, that equates to this: "WILL CHAIR COMM AND TECH SUB 73S W7EQI."

Amateur Radio Beacons

I was talking to some friends today about beacons and the MFJ-890 DX Beacon Monitor.
I know of three Amateurs that have the MFJ-890. They all say it is a great conversation piece and also make the shack look cool.
My friend Bryce sent this e-mail to me.

The Northern California DX Foundation (NCDXF)operates eighteen beacons on five continents which transmit in successive one-minute intervals on 14.100, 18.110, 21.150, 24.930 and 28.200 MHz.

The NCDXF beacon call sign and the first dash is sent at 100Watts. The remaining dashes are sent at 10Watts, 1 Watt and 0.1 Watts. Very handy info for QRPers!

Almost all ten meter beacons transmit between 28.190 MHz and 28.300 MHz. You will find a comprehensive list at this URL

TEN METER PROPAGATION BEACONS

Six meter beacons are mostly found between 50.0 MHz and 50.1 MHz, with a concentration between 50.06 MHz and 50.08 MHz.

One example is W4CLM/B transmitting 30 Watts continuously into a vertical on 50.065 MHz (+/-) from location EM74 (Atlanta, GA.).

FCC; Amendment of the Amateur Service Rules

New rules affecting vanity and club station call signs within the Amateur Radio Service were published in the Federal Register. These new rules will go into effect on February 14, 2011. Thirteen months ago, the FCC announced its intention of modifying Part 97 as it applies to the vanity call sign system and club station call signs, aligning the rules to prior Commission decisions. Last month, the Commission released a Report and Order (R&O), outlining its decision. Along with the changes to the call sign rules, the FCC made “certain minor, non-substantive amendments” to portions of Part 97. (ARRL - FCC)

Amateur Radio Society GETS the BOOT

Wow, what am I to say?
"Regulations governing child welfare can make it difficult for a school to manage certain situations in which outsiders use the premises, while at the same time ensuring the school remains fully compliant with regulatory requirements".
What a bunch of Hooey!!!!
I am so tired of this, all the school needs to do is operate this practice as they do during regular school hours or follow guide lines that the Boy Scouts of America operate by.
No wonder the Middle Eastern Countries are out performing the United States.
Read the full story here. It's over and out for the radio amateurs.

The ever Active Sun

A global eruption on the sun has shattered old ideas about solar activity. Researchers presented their surprising findings at a press conference Monday at the American Geophysical Union meeting in San Francisco. Get the full story from Science@NASA.
Hoping it will make the DX better.

A Great Book about Amateur Radio

I got a book from a friend a few months ago and I just finished reading it. I am a discouraged with myself for letting this incredible book sit on my desk untouched for so long.
The book,
The World of Ham Radio, 1901-1950: A Social History
by Richard A. Barlett

During the first fifty years of the twentieth century, ham radio went from being an experiment to virtually an art form. Because of the few government restrictions and the low monetary investment required, the concept of ham radio appealed to various people. More than just a simple hobby, however, ham radio required its operators to understand radio theory, be able to trace a schematic and know how to build a transmitter and receiver with whatever material they might have available. With the advent of World War II and the increased need for cutting-edge communications, the United States government drew upon the considerable knowledge and skill of these amateur ham radio operators, validating the fact that ham radio was here to stay.

This book explores the history of ham radio operators, emphasizing their social history and their many contributions to the technological development of worldwide communications. It traces the concept of relays, including the American Radio Relay League, from contacts as close as 25 miles apart to operators anywhere in the world. The book highlights the part played by ham radio in many of the headlined events of the half century, especially exploration and aviation "firsts". The ways in which these primarily amateur operators assisted in times of disaster including such events as the sinking of the Titanic and the 1937 Ohio River flood, are also examined.

A CW Story.

Back when the telegraph was the fastest method of long-distance communication, a young man applied for a job as a Morse Code operator. Answering an ad in the newspaper, he went to the office address that was listed. When he arrived, he entered a large, busy office filled with noise and clatter, including the sound of the telegraph in the background. A sign on the receptionist's counter instructed job applicants to fill out a form and wait until they were summoned to enter the inner office.

The young man filled out his form and sat down with the seven other applicants in the waiting area. After a few minutes, the young man stood up, crossed the room to the door of the inner office, and walked right in. Naturally the other applicants perked up, wondering what was going on. They muttered among themselves that they hadn't heard any summons yet.

They assumed that the young man who went into the office made a mistake and would be disqualified. Within a few minutes, however, the employer escorted the young man out of the office and said to the other applicants, "Gentlemen, thank you very much for coming, but the job has just been filled." The other applicants began grumbling to each other, and one spoke up saying, "Wait a minute, I don't understand. He was the last to come in, and we never even got a chance to be interviewed. Yet he got the job. That's not fair!"

The employer said, "I'm sorry, but the last several minutes while you've been sitting here, the telegraph has been ticking out the following message in Morse Code: 'If you understand this message, then come right in. The job is yours." None of you heard it or understood it. This young man did. The job is his.

Snow Collapse of Minneapolis Metrodome

Wow, what a mess for Brett and the boys.

Distracted Driving Legislation

I have heard of laws being passed throughout the world and it seems they are getting ever close to reality here in the U.S.A. at times. Well this is what is going on with our northern neighbor.

Distracted Driving Legislation Continues to be on Provincial Agendas; New Brunswick introduces Legislation Banning Cell Phone and Two Way Radio Use

Most provinces [eg. Nova Scotia, Manitoba, BC, Quebec, Newfoundland and Labrador to name five] have chosen not to restrict the operation of mobile amateur radio equipment during driving. These governments have recognized the value of amateur radio to their citizens. Amateur radio has served the citizens of Canada during such emergencies such as floods, dangerous weather and ice storms, in support of public events such as Marathons and in support of agencies such as the Red Cross and a variety of provincial and municipal agencies across Canada. The support provided by amateur radio is frequent, freely given and in the highest standard of public service.

HOW TO READ PROPAGATION NUMBERS

The A index [ LOW is GOOD ]

  • 1 to 6 is BEST
  • 7 to 9 is OK
  • 11 or more is BAD

Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.

A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.

SFI index [ HIGH is GOOD ]

  • 70 NOT GOOD
  • 80 GOOD
  • 90 BETTER
  • 100+ BEST

The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.

Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.

K index [ LOW is GOOD ]

  • 0 or 1 is BEST
  • 2 is OK
  • 3 or more is BAD
  • 5 is VERY VERY BAD

The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.

A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
