    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

U.S. Defense & Homeland Security

This page exists to provide resources for engineers interested in serving the United States defense industry. Since the terrorist attacks on U.S. soil on 9/11/2001, there has been a new emphasis on guarding the security of our homeland. In his 2002 "State of the Union Address," President Bush appealed to all Americans to perform 2000 hours of volunteer work for the good of the country. Maintaining an area on RF Cafe that is dedicated to companies supporting the mission will serve as part of my effort (in addition to the four years already spent in the USAF).

The Silent Guard of America's Memorials

You are needed to help guard the Vietnam Veterans Memorial (The Wall) from vandals during the anti-war march in Washington, D.C., on March 17, 2007. Our politicians are too weak to have these people arrested, as we saw in January when protestors spray painted the Capitol building steps. Please click the Gathering of Eagles link above to see how you can help.

Additionally, 6,010 American veterans and others are interred in the Mexico City and Corozal American Cemeteries.

"These are the times that try men's souls. The summer soldier and the sunshine patriot will, in this crisis, shrink from the service of their country; but he that stands it now, deserves the love and thanks of men and women."    -- Thomas Paine, The Crisis (1776)

September 11, 2001 Remembered (2013)

Click here to visit the U.S. Marine Corps website"Front PageThe proud warriors of Baker Company wanted to do something to pay tribute to our fallen comrades. So since we are part of the only Marine Infantry Battalion left in Iraq the one way that we could think of doing that is by taking a picture of Baker Company saying the way we feel. It would be awesome if you could find a way to share this with our fellow countrymen. I was wondering if there was any way to get this into your papers to let the world know that "WE HAVE NOT FORGOTTEN" and are proud to serve our country."

September 11, 2001 - Never Forget

Islamic terrorist attack on UAL Flight 93, September 11, 2001 - RF cafeIslamic terrorist attack on the Pentagon, September 11, 2001 - RF CafeIslamic terrorist attack on the twin towers, September 11, 2001 - RF CafeIncredibly, 18 years has passed since the extremist Islamic attack on American soil on the morning of September 11, 2001. Nearly 3,000 citizens died that day. World leaders have embarked on a path of colonizing our homelands with groups of
people that are known to harbor sympathies for the terrorists. They dwell among us now and mean to do us harm when opportunity presents itself - which it has on numerous occasions in the past many years. Never forget the people who died in the burning towers, the Pentagon, and the airplanes, and those left behind to grieve and get on with life. Never forget the police and military members who fought - and some died - to keep us safe and free. Never forget the rotten politicians who imperil our existence with their selfish agendas.

A True Story... ;-)

A Soldier, a Sailor, an Airman and a Marine got into an argument about which branch of the service was "The Best." The arguing became so heated the four service men failed to see an oncoming truck. They were run over by the truck and killed instantly.

Soon, the four servicemen found themselves at the Pearly gates of Heaven. There, they met Saint Peter and decided that only he could be the ultimate source of truth and honesty. So, the four servicemen asked him, "Saint Peter, which branch of the United States Armed Forces is the best?" Saint Peter replied, "I can't answer that. However, I will ask God what He thinks the next time I see Him. Meanwhile, thank you for your service on Earth and welcome to Heaven."

Some time later the four servicemen see Saint Peter and remind him of the question they had asked when first entering Heaven. The four servicemen asked Saint Peter if he was able to find the answer. Suddenly, a sparkling white dove lands on Saint Peter's shoulder. In the dove's beak is a note glistening with gold dust. Saint Peter opens the note, trumpets blare, gold dust drifts into the air, harps play crescendos and Saint Peter begins to read the note aloud to the four servicemen.

Great Quotation

"The elite didn't realize there was a revolutionary transformation going on in American society. We're starting to see the military dividends of that in this generation, who are not afraid of the things that terrified their parents. They have sort of a pop-culture casualness about them — Ray-Ban sunglasses, big muscles, dyed hair — but a deadly seriousness. And there is not that Letterman-Seinfeld cynicism of that smart-ass urban elite."

"This war is not only going to have positive effects on the Middle East, but it's going to create a whole generation of young people with shared sacrifices. People admire those who risk their lives to protect the security of their fellow Americans. It's a marked contrast to the “vomit-ins” in San Francisco or “die-ins” in the streets of Washington. But it's going to take a while for those people to pass through the institutions and leave us in peace."

"One, we have a conventional military that's very powerful, and we're not necessarily predictable. We have emotions, too, and we can lash out if we have to, so if you are rash terrorists you'd better be careful of our anger. Two, when leaders like the Assads or the Khadafis look at what we did to Saddam Hussein, blowing up individual homes and rounding up killers, we almost reinvented their own military dialectic. They always threatened us with these random stealthy killers; now in response we're saying, 'You may have a suicide bomber, but we can target you as unpredictably and suddenly just as much as you can target us.'”

 - historian Dr. Victor Davis Hanson, describing the Operation Iraqi Freedom troops and the media elite that misjudged them.

Veterans Day 2020: A Pittance of Time

Veterans Day 2016 (Snoopy copyright) - RF Cafe This is my annual Veterans Day tribute. On November 11 (the 11th day of the 11th month), at 11:00 am (the 11th hour), we observe 2 minutes of silence in honor of countrymen who "gave the last full measure of devotion." A Pittance of Time is performed by Canadian citizen Terry Kelly (he went blind at an early age). It was written after an experience he had on Veterans Day in 1999. It is done in the finest Celtic tradition.

See AP's Original Wired D-Day Invasion Story

AP's Original D-Day Invastion Field Report - RF CafeOn June 6, 1944, the Associated Press' (AP) Wes Gallagher filed the first news report from the beachhead at Normandy. The code name was "D-Day" (see today's RF Cafe logo). It has now been 70 years since the day "American, British and Canadian forces landed by daylight in massive strength on the Normandy coast of France today and sped inland from quickly-established beachheads. Gen. Dwight D. Eisenhower told his troops this grand assault was a crusade which must bring 'nothing less than full victory.'" The animation below shows day-by-day progression of WWII in all theaters of operation - sobering to see how bad things got before the U.S. entered the war.

Gettysburg Address

Four score and seven years ago our fathers brought forth on this continent, a nw nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.

Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battlefield of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this.

But, in a larger sense, we can not dedicate - we can not consecrate - we can not hallow - this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us - that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion - that we here highly resolve that these dead shall not have died in vain - that this nation, under God, shall have a new birth of freedom - and that government of the people, by the people, for the people, shall not perish from the earth.
