Hi, this is an introductory video about the new ZBitX.

大家好，這是一段關於全新 ZBitX 的介紹視頻。

情態副詞

The only difference between this and a full-fledged SDR like the SBitX being lower power.

它與 SBitX 等正式 SDR 的唯一區別是功耗更低。

It runs exactly the same software and it's capable of exactly the same things.

它運行完全相同的軟件，也能做完全相同的事情。

So this is also a field radio because of its small size.

由於體積小，這也是一款野外收音機。

So, yeah, it's about 13 actually, 13 ounces in weight without the battery.

所以，是的，不含電池的重量約為 13 盎司。

So we'll talk about the batteries in a bit.

And this is about less than 5.5 inches across.

And this is about less than 1.5 inches deep.

So you could have put this in your pocket except for the tuning knob.

是以，除了調諧旋鈕之外，你完全可以把它放進口袋裡。

And tuning knob is actually very critical for radio hams.

實際上，調諧旋鈕對無線電火腿來說非常關鍵。

So we've retained the tuning knob, although I did try user interfaces without using the tuning knob.

是以，我們保留了調諧旋鈕，不過我也嘗試過不使用調諧旋鈕的用戶界面。

This comes fully built for $149, which is the current price.

It may go up or come down depending on the duty structures prevailing in the international market.

根據國際市場現行的關稅結構，它可能會上升或下降。

And it runs all digital modes, FLDG, WSJTX, and there are others which will follow.

它還能運行所有數字模式、FLDG、WSJTX 以及其他即將推出的模式。

So apart from the antenna, this is a complete set.

是以，除了天線之外，這是一套完整的設備。

是以，這裡有鑰匙、麥克風和耳朵。

You can add HDMI to this when you're at home so that you can use this with a larger monitor.

在家時，您可以為它添加 HDMI 接口，這樣就可以與更大的顯示器一起使用了。

And there are certain settings and configurations which are only possible on the large screen.

有些設置和配置只能在大屏幕上進行。

So you might want to use this when you're at home.

是以，你可能想在家裡使用它。

On the USB port, we supply a small dongle which will plug into this and give you a regular USB at the other end.

關於 USB 端口，我們提供了一個小型加密狗，它可以插入該端口，並在另一端為您提供普通 USB 接口。

Right now I've connected it to my Logitech wireless keyboard and mouse.

現在，我把它連接到羅技無線鍵盤和滑鼠上。

What's marked here as CAT is actually the second CPU of this system, which is the Pico.

這裡標註為 CAT 的實際上是該系統的第二個 CPU，即 Pico。

And the Pico basically controls the front panel, so you can use this to upload the firmware for the Pico.

Pico 基本上控制著前面板，所以你可以用它來上傳 Pico 的固件。

As well as the forthcoming CAT control can happen from this.

此外，即將到來的 CAT 控制也可能由此產生。

So you can actually connect it to your laptop in case you would need that, although everything is built into this itself.

是以，您可以將它連接到筆記本電腦上，以備不時之需。

Now you can supply 6 to 9 volts for the rated 5 volts power.

現在，您可以為額定的 5 伏電源提供 6 至 9 伏電壓。

And now the back plate is itself used as a heat sink.

現在，背板本身也被用作散熱器。

These are the two studs which go through the power transistors inside this.

這兩個螺柱穿過內部的功率半導體。

But otherwise, this will get warm when you're using it.

So it's preferable that instead of keeping it flat like that, you keep it slightly at an angle by putting something underneath it.

是以，最好不要讓它像這樣保持平整，而是在它下面放一些東西，使它保持稍微的角度。

Or if you're in the field you can hold it, in which case there's no problem at all.

或者，如果你在野外，你可以拿著它，這樣就完全沒有問題了。

So that's about the physical dimensions and the connectors etc.

當然，這裡還有一個 BNC 連接器。

And now I'll just come to the battery in the end.

現在，我就來看看最後的電池。

So the battery, this is a 2 LiPo battery case which is bolted onto the side of this.

電池，這是一個 2 號鋰電池盒，用螺栓固定在側面。

如果你願意，可以把它拿出來。

You just take out these two screws and this side panel will pop out.

只要擰下這兩顆螺絲，側板就會彈出來。

And there are two screws which hold this here.

You can remove these two screws and you're off the battery.

卸下這兩顆螺絲，電池就卸下來了。

Which might actually reduce the physical dimensions of this.

這實際上可能會縮小它的物理尺寸。

The reason why we have not given a charger or inbuilt batteries is that if you try charging the batteries while the radio is running, there's a lot of noise which will come into the radio because of the sort of charges that are available.

我們之所以沒有提供充電器或內置電池，是因為如果您嘗試在收音機運行時給電池充電，那麼收音機就會因為充電而產生大量噪音。

So instead of that, you have to plug in chargeable cells here and this connects back to the power supply.

是以，你必須在這裡插入充電電池，然後將其連接回電源。

The battery case is not integral to the radio itself.

電池盒與無線電本身並非一體。

And switching on the radio is fairly simple.

Wherever you have, right now I have about 8.2 volts which is the voltage that I always operate my radio on.

不管你的電壓是多少，現在我的電壓大約是 8.2 伏，這也是我一直使用的收音機電壓。

You just have to plug in the wire and there we are.

你只需插上電線，我們就可以了。

Now what it will say here is that it's waiting for the SBITX to start.

現在它將在這裡說明，它正在等待 SBITX 啟動。

And that is because the SBITX actually runs on the Raspberry Pi and that being a Linux machine will take about 15 to 20 seconds to boot up.

這是因為 SBITX 實際上是在 Raspberry Pi 上運行的，而 Raspberry Pi 是一臺 Linux 機器，啟動大約需要 15 到 20 秒。

And here you can see the version which is 1.03 of the firmware.

在這裡，你可以看到固件的版本是 1.03。

Probably by the time you see this, we would have moved on to 1.04.

也許當你看到這篇文章時，我們已經進入了 1.04 版。

And the way this works is, it's a resistive touch screen.

它的工作原理是，這是一個電阻式觸摸屏。

So whatever you want to touch, you have to essentially tap on that and you'll see this white box which comes around it.

是以，無論你想觸摸什麼，你都必須點擊它，然後你就會看到它周圍的白色方框。

Let me see if I can find another station.

讓我看看能否找到另一個電臺。

Now these controls here are common to all the modes.

現在，所有模式都可以使用這些控制按鈕。

And what you see here, this open wipe to save are part of the logging software.

你在這裡看到的，這個打開的擦拭保存都是日誌軟件的一部分。

So this is my log of my attempts at doing everything.

這就是我的日誌，記錄了我嘗試做的所有事情。

As you can see, I've done a lot of FTAs on this radio.

正如你所看到的，我在這臺收音機上做了很多 FTA。

And you can click and on the radio itself, you can just delete it if you want to, but we'll not do that right now.

你可以點擊無線電本身，如果你想刪除它，也可以直接刪除，但我們現在不會這麼做。

所以，讓我看看能否看到一些自貿協定。

於是，我從菜單中找到了波段開關。

For each of the bands, there are four different settings.

So let me go to 15 meters and see if there's anything interesting there at all.

讓我轉到 15 米處，看看那裡有沒有什麼有趣的東西。

I don't hear anything probably because my high up gain is low.

我聽不到任何聲音，可能是因為我的高增益太低了。

And I can, the span is too small to see this.

All you need to do is you need to add your call sign.

您需要做的就是添加您的呼號。

But we will take this setup in the next video.

不過，我們將在下一個視頻中進行這一設置。

I just wanted to show you how the controls work here.

我只是想告訴你這裡的控制是如何工作的。

And to switch it off, you just take the power off.

要關閉它，只需切斷電源即可。

我們將在未來的視頻中看到更多內容。
