The 803 spark transceiver will be a thing of the past

All along, Yu Hewei has been fully supporting Xiao Fei's work, giving money if he needs money, looking for schools for him if he needs people, and even going directly to Sun Lao and Lao Ba to ask for them, and his attention is not at all like ---- other industries to audit and review, and in the end, he picks his nose and picks his eyes......

For example, when someone else asks for a project to invest in the "North Fund", President Yu pulls the abacus beads at every turn to calculate the cost, and it is actuarial---- after all, President Yu has an actuary's license in the old world, if you talk about the ability of financial accounting to engage in financial insurance models and investment business plans, you can simply throw off everyone in this era several streets, it is estimated that the famous European mathematicians in this era can not catch up with him - although these famous mathematicians are Yu Hewei's grandfather, but now it is the front wave that pushes the back wave, and the front wave dies on the beach, in short, No one wants to be sloppy in front of President Yu.

And after President Yu calculates a set of benefits and costs, if he thinks your plan is not bad, he will generally approve it, but the silver will never give more than one point - in short, it is a special picking.

However, the investment of "Beishang Fund" in Xiao Fei's electronic studio can be said to be regardless of the cost, and President Yu's principle is: only ask about the need, not the cost.

The one who enjoys this treatment, probably except for Xiao Fei's electronics studio, is the doctors' Wuzhou Pharmaceutical.

For these two companies, the "Northbound Fund" basically does not calculate, usually a report is typed, President Yu thinks it is good after reading it, and signs it with a wave of the pen, and then gives money and materials to people.

Obviously, as a professional who has worked as a financial platform and engaged in venture capital in the old world, he can see the prospects of an industry better than anyone else.

He already knew that the vacuum tube that Xiao Fei made a while ago was the biggest bottleneck in the electronics business of all traversers, and it was the most important project, so for a year, Yu Hewei had invested in Xiao Fei's side at all.

In fact, as far as the current conditions are concerned, this kind of vacuum glass tube glass factory is not impossible to do, as long as you are willing to spend time and invest in equipment, and you can definitely get out of the scrap rate or something-so Yu Hewei really allocated a large budget for Xiao Fei to make this thing.

In the process of developing a completely space-time radio, the first bottleneck problem encountered by Xiao Fei was the material, so Yu Hewei coordinated in the middle, contacted and coordinated with Xiao Fei one by one, and finally solved the copper wire problem of the frequency selection coil for him in Anhengtong.

Next, Holley successfully replaced the selenium steel sheet in the step-up transformer with a magnetic core material, and as for the resistor, capacitor, mechanical oscillator, that is, relay and other components, Yu Hewei has also been solving problems for Xiao Fei.

After the problem of electronic components is basically solved, the main problem that follows is the power supply, according to the existing conditions, large solid-state batteries are still not to think about now, at least three or five years, Xiao Fei finally decided to use semi-solid batteries instead, although it is bulky, but it can also be used, there is no way to be this condition now.

The charging problem of the battery is solved by the foot generator, obviously it is a difficult thing to make a self-made generator---- especially the rotor coil of the generator, because the copper enameled wire process equipment on the side of Anhengtong has not yet been made, so it can only use thick copper wire, plus the unknown insulating material made by the by-product of tung oil and coal coke chemical industry, you can imagine, how large is the volume of this generator......

Fortunately, Qiao Xiaomu's glass factory lived up to expectations, and within a few months, Xiao Fei's glass vacuum tube changed from the size of a fire extinguisher to the size of a water cup — the kind of two-liter beverage bottle.

Subsequently, Xiao Fei not only created a two-pole vacuum tube, but also a three-pole vacuum tube and a five-pole vacuum tube, which was a scientific and technological breakthrough of great decisive significance for insiders.

Immediately afterwards, with the vigorous cooperation of Cao Limei and An Hengtong, Xiao Fei obtained thin aluminum sheets and copper and aluminum wires that were twice as thin as before.

Of course, the so-called thin aluminum sheet is about a millimeter thick, and the so-called fine copper and aluminum wire, which is really coarse---- is almost a millimeter in diameter, and the purity of the material seems to have some problems, after all, there is no ready-made processing equipment, all of which have to be made by Shuguang Machinery Factory, and Boss Luo has also invested a lot of manpower and material resources for this.

In addition, with the support of the "Beishang Fund", Baisha Group used the by-product of coal coke chemical industry to produce a substance suspected to be plastic, which is probably a polyvinyl chloride-based material, which has good ductility and can be pressed into a thick film----.

In short, the success of the production of the above three main types of materials has improved Xiao Fei's electronic components by more than one grade, and now the large capacitors in his high-power radio station are made of this thin aluminum plate and the insulating materials provided by Baisha Group, plus the iron core, carbon-based resistance materials provided by Xiliu Iron and Steel Group and the blister copper and aluminum wire provided by Anhengtong, Xiao Fei has successfully created inductance coils, transformers, potentiometers and resistors, and on this basis, he has hand-made relays, band switches and frequency selection coils and so on.

Subsequently, Baisha Group provided Xiao Fei with battery electrolyte and graphite electrode, and in this way, the battery for the radio station was finally produced.

Eventually, Xiao Fei replaced the inefficient foot-operated generator with a Stirling engine, and with a rechargeable battery, he finally got all the elements needed for a high-power radio station.

So from then on, Xiao Fei finally began to make radio stations in the real sense of the word - for this reason, Xiao Fei confidently announced to everyone that it is expected that within five to ten years, all our radio communications will be long, medium and short wave radio transceivers, and the era of spark transmitters will soon become history.

After Li Junming received a telegram from the Asian American Communications Company at the "Container Castle" in Zixia Town (this is the evaluation of Zhu Beiguo and others after visiting the governor's mansion and school where Li Ren and the others lived), he immediately called back Xiao Fei and said: As the governor of Zixia Island, I certainly have no opinion on the investment plan of Asian American Communications on Zixia Island, but Ren Ke's garrison definitely needs the kind of wagon-pulled radio you mentioned last time.

Now that Ren Ke has set up a garrison, there are currently more than 1,100 people, and it will be expanded in the future, and it is obvious that he needs this relatively portable radio station very much.

Immediately afterwards, Li Junming changed his words in the telegram: In fact, what Ren Ke needs most at present is weapons and equipment, and the Zixia Island garrison currently only has 100 Type 57 rifles and a small number of Type 57 grenades @ bullets, and these equipment were still supported by Xiao Ai on Wanshan Island at the beginning, but the Federal Ministry of Finance has only temporarily allocated him a capitation fee of two taels of silver per person per month, and there is no budget for weapons and ammunition at all, which makes it difficult for Zixia Island to even continue daily training.

Xia Xiaoou immediately called and said: It is true that weapons and equipment have not been sent to Zixia Island, because the budget at that time was still before the Changfeng operation, and naturally there was no budget for the purchase of weapons and ammunition for the Zixia Island Garrison at that time, and the current head fee expenditure of the Zixia Island Garrison is still temporarily paid from Sun Lao's presidential special budget.

It's already August, so it's enough to use Sun Lao's presidential special budget to pay for the head fee of the Zixia Island Garrison, even if Ren Ke expands the army several times, it is enough to pay for it, and as for the official budget of the Zixia Island Garrison, it may have to wait for the next year's fiscal year.

After all, Zixia Island is not directly facing the threat of force now, and because the scale of the Changfeng Action Plan is getting bigger and bigger, the capital chain of the Ministry of Finance has been a little tight recently, so the Zixia Island Garrison will endure it and maintain the status quo for the time being.
