On the third day after Li Kangping met with Sommerfeld, he received a call from Sommerfeld and immediately went to the hotel where Sommerfeld was staying.

The table in the hotel was covered with papers, and Sommerfeld said with a complicated expression: "I have read the paper you gave me, and according to Professor Arthur Compton's paper, the wave theory of Roentgen rays must be definitively abandoned. However, I am not quite sure that Professor Arthur Compton is right, and I would like to visit Professor Arthur Compton's laboratory and talk to him in person. Lee, you know Professor Arthur Compton, and Professor Duane certainly knows Professor Arthur Compton. However, you said that Professor Arthur Compton had a dispute with Professor Duane, so, I wanted you to contact Professor Arthur Compton, can you do that? ”

"I can do that, and I think Professor Arthur Compton would be happy to see you in Chicago."

Li Kangping arranged that Sommerfeld would go to Chicago in a few days, and Arthur Compton and Wu Youxun would receive Sommerfeld in Chicago with the warmest and most sincere attitude.

It is said that under Liu Shaowen's operation, Manhattan Zeus Company used its Hera Mahjong Company as collateral to borrow $700,000 from Citibank.

Edwin Armstrong thought about it for a while, and he decided to sell the patent for the superheterodyne radio to Li Kangping.

Armstrong gave up on his dream of becoming a millionaire and asked for $500,000.

"Edwin, I'll give you $500,000, but pay it over 11 years." Li Kangping said.

Eleven years later, in 1934, Armstrong's patent protection for superheterodyne radios expired.

Armstrong agreed to this condition and signed.

On the day the patent transfer contract was signed, Armstrong received a check for $45,000. From now on, the patent for superheterodyne radio belongs to Manhattan Zeus.

Manhattan Zeus then acquired the East Bay Radio Company in Jersey City for $130,000.

Li Kangping proposed that the Eastern Bay Radio Company be renamed the "Poseidon Radio Company," which was the third wholly-owned subsidiary of the Manhattan Zeus Company.

In the early days of the Poseidon Radio Company, the financial pressure was extremely high.

Citibank's loan of $700,000 and the debt owed by Eastern Gulf Radio Company are close to $500,000, and the two debts together are about $1.5 million when interest is included.

Of course, Radio Poseidon does not have to pay off the $1.5 million immediately, and the company will repay it in installments over several years.

The headquarters of Zeus Corporation in Manhattan had $1 million in liquidity, of which $900,000 went to the Poseidon Radio Company.

The owners of the Eastern Bay Radio Company are all gone, leaving behind 36 acres of factory and more than 130 workers.

John Saunders, a 50-year-old middle-aged white man who was the deputy general manager of the Eastern Bay Radio Company.

Li Kangping first interviewed John Sanders, who he wanted to continue working for Poseidon Radio.

"John, you are most familiar with this place, and have a wealth of management experience, I would like to appoint you as the general manager of the Poseidon radio company, and your salary will be raised to the same amount as the general manager of the Eastern Bay Radio Company, can you accept it?" Li Kangping asked.

"Dr. Lee, I accept your offer and thank you for doing so." John Saunders said sincerely, and in an instant, he said with a sad face: "Now, the debt of the Poseidon Radio Company is not more than 400,000 dollars, but close to 1.5 million dollars. How can we make a radio company with heavy debt, sluggish sales, and on the verge of bankruptcy experience the joy of profitability? ”

"John, since you're the general manager, I'm going to tell you the company's secrets. What sets Poseidon Radio apart from the Eastern Bay Radio Company is that we have unique products--- superheterodyne radios and super-regenerative radios. Believe me, John, that with these two powerful weapons, we can turn a profit. ’”

Li Kangping retained more than 100 veteran employees such as John Saunders, and then transferred a technical team specializing in radio from Zeus Laboratory.

Television is a new thing, and with the exception of a very few people such as Theodore, most of the engineers at Zeus Lab were not TV engineers before.

Before they came to Zeus's laboratory, most of them worked on radios, vacuum tubes, and other electrical appliances.

Alex is a radio expert who worked for two years as a technician at a radio factory in Texas.

"Alex, I would like to appoint you as the deputy general manager of the Poseidon radio company, you are in charge of technology." Li Kangping continued to arrange his troops.

As a result, Alex became the deputy general manager in charge of technology at Poseidon Radio.

The Poseidon Radio Company has a patent for a superheterodyne radio and has obtained a full set of technical information and physical objects provided by Armstrong.

At present, the structure of the mainstream product in the American radio market is very simple, it is composed of a receiving antenna, an input circuit, a high-amplification circuit, a detection circuit, an audio voltage amplification and a power amplifier.

In order to be able to receive more distant radio waves and to select the desired radio signal from an increasing number of radio station signals, higher requirements are placed on the sensitivity and selectivity of radios.

On the basis of the repeater structure, the superheterodyne radio adds the local oscillation circuit and mixing circuit, as well as the intermediate frequency amplification link. The sensitivity and selectivity of the superheterodyne radio are mainly determined by the circuit gain and frequency selectivity of the intermediate frequency amplification link, which greatly improves the selectivity and sensitivity of the superheterodyne radio.

Armstrong invented the superheterodyne radio in the laboratory, and he had no experience in the industrial production of superheterodyne radios, and no one had such experience.

"So, Alex, based on the product characteristics of superheterodyne radios, we need to revamp the production line of Poseidon Radio."

"At the same time, my patented ultra-regenerative radio does the same."

"After the completion of the renovation, our company's production line no longer produces ore machines and repeaters, but is all used to produce superheterodyne radios and super-regenerative radios."

"The performance of superheterodyne radios is better, defined as a high-end product, and the proportion of production capacity is tentatively set at 80%. Ultra-regenerative radios are defined as mid-range products, accounting for 20% of production capacity. ”

"Alex, please lead your radio technical team and start working on this technology right away."

Counting Alex, a total of 25 technicians from Poseidon Radio Company were transferred from Zeus Laboratory, and these 25 people are the core technical team of Poseidon Radio Company.
