Apple Needs Some RF Design Engineers

Apple Needs Some RF Design Engineers

A Chinese man walks past a authorized Apple retailer in Beijing on July 12, 2010. Despite a new flagship showroom that just opened in Shanghai, Apple is striving to overcome price disadvantages and an underground market.

Yep, as I suspected….

It’s official. Consumer Reports’ engineers have just completed testing the iPhone 4, and have confirmed that there is a problem with its reception. When your finger or hand touches a spot on the phone’s lower left side—an easy thing, especially for lefties—the signal can significantly degrade enough to cause you to lose your connection altogether if you’re in an area with a weak signal. Due to this problem, we can’t recommend the iPhone 4.

That’s Consumer Reports, incidentally, which put the phone in an RF-isolated room to perform their tests along with a base-station emulator.

Oops – that’s about as close to proof as you’re going to find.  In an RF-quiet environment it’s pretty easy to prove your case, and it appears that CR did so.

The tests also indicate that AT&T’s network might not be the primary suspect in the iPhone 4′s much-reported signal woes.

"Might" not?  

I have never been impressed with the iPhone (any generation) in terms of RF.  Ever. It has always been a "form before function" device from my perspective, all the way back to the original units.  Then again I’m spoiled – the best RF-performing GSM phone I’ve ever used was a Nokia 3395.  I may still have one laying around here somewhere, and all of my old Nokias (including a 6610 which was nearly as good) still work just fine.  Old, yes, but one thing Nokia does know how to do is design and build an RF section.

Incidentally, buying devices that work before selecting them for "sex appeal" may be why I’ve never had a material problem with the "can you hear me?" BS that so many suffer with when it comes to cellphones.  I guess my view is that a cellphone is for communicating rather than trying to shag some hot chick at the local bar by flashing my "bling."

This is a common flaw for consumer devices – be sexy rather than be smart – or good.  Of course sex sells, and so the more "sexy" you can make something look the better it sells, and as long as you remain within the "acceptable" functionality envelope you don’t get hurt – too badly.  Witness Motorola, which had the "hot" phone for a long time…

Powell's Stock Trades Leaked, Show Multi-Million Sale As Market Tanked

With leaked trades in their personal accounts already costing two Fed presidents their jobs, and a third - vice chair Richard Clarida - currently on the ropes amid speculation he will soon follow, a few weeks ago we joked that if forces within the Fed want to get rid of all the hawks, they should just leak Esther George - the Fed's last remaining uberhawk - trading record.

Price and Volume Swing Analysis on Bitcoin and Silver

Courtesy of Read the Ticker

Many take guidance from news, pundits or advisors. Well sometimes the swings of price and volume are a better measure of what happens next.

The big boys do not accumulate or distribute in single 1 second trade, they build positions over weeks, months and years. They use price swings in the market to build or reduce positions, and you can see their intent by studying swings of price and volume and applying Tim Ord logic as written in his book called 'The Secret Science of Price and Volume: Techniques for Spotting Market Trends, Hot Sectors, and the Best Stocks'.

Tim Ord is a follower of Richard Wyckoff logic, his book has added to the studies of Richard Wyckoff, Richard Ney and Bob Evans.

Ethereum's Turn To Outshine Bitcoin Is Coming, UBS Says

Courtesy of ZeroHedge View original post here.

After a stellar start to the year, which saw its price soar to an all time high above $4,100, trouncing virtually all of its crypto peers, Ethereum has stagnated in recent weeks, with its place in the spotlight taken by bitcoin whose impressive outperformance has been the result of now confirmed speculation that a bitcoin futures ETF is coming. It also meant that what has traditionally been a close correlation between the two largest cryptos has broken in favor of the larger peer; it would also suggest that ethereum is trading about $1000 cheap vs bitcoin.

Crude Oil Cleared For Blast Off On This Dual Breakout?

Courtesy of Chris Kimble

Is Crude Oil about to blast off and hit much higher prices? It might be worth being aware of what could be taking place this month in this important commodity!

Crude Oil has created lower highs over the past 13-years, since peaking back in 2008, along line (1).

It created a “Double Top at (2), then it proceeded to decline more than 60% in four months.

The countertrend rally in Crude Oil has it attempting to break above its 13-year falling resistance as well as its double top at (3).

A successful breakout at (3) would suggest Crude Oil is about to mo...

The past year has underscored that challenge. The pandemic has not just affected investment returns – it’s also had serious implications for charitable activities and the ability to fundraise. For some organizations, it’s even raised doubts about whether they can continue to operate.

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Courtesy of Technical Traders

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
