我已經比較就沒有抱怨,所以應該可以,對不對?謝謝。我最近有買雙頻手機,因為終於想用中繼器。不過,到現在連一個QSO都沒有。

對一個歐洲人來說,台灣的中繼器真“特別”。多年前,我在台中有機會看人家組裝,安裝,踩下一台“中繼器”。那其實是一台Alinco的雙頻車機,設crossband repeater模式,然後接兩個烏龜:144跟430各一台功率放大器。那中繼器有裝在一個黑色的金屬盒(有風扇,但這還有什麼用?),然後裝在一棟高樓的屋頂上,也就是說在太陽下。需不需要解釋那台中繼器變成怎樣?不用吧。

為什麼台灣現在只有430的中繼器,沒有144的?是不是因為日本也沒有?各位有沒有發現其它國家在144也有中繼器?而1200或甚至2400也可能有。日本不是唯一有業餘無線電的國家。不過,他們也用漢字,所以對台灣人而言也許一些事情比較容易”參考“…

雖然台灣的法律會提到中繼器,但是聽說無法申請。那麼,如果根本沒有辦法申請,NCC考試的時候應該不用煩我們這種沒有意義的事?應該要問他們一下… 我也聽說目前的中繼器是為了緊急通訊而設的。所以,如果有台風或地震,一般的通訊設備都刮掉了,我們的中繼器應該會提供通訊服務,對不對?不過,我用新買的這台手機,連在最高功率設定從高雄市區沒有辦法開負責高雄的C6:從左營不行,從三民不行,從小港不行。看起來,下次台風或地震來,我最好不要依賴這些中繼器…

那我們談一下技術… 一段時間前我在Skype聊天室看到人家提到中繼器的輸入頻率都一樣。我看到差一點婚到了。兩個FM電台在同一個頻率發射,請問發生什麼事?干擾!如果你運氣不好,你什麼都聽不懂。如果運氣好一點,其中一個電台會比較強,所以至少可以聽到他。看起來當時終於有人發現幾台中繼器用同一個輸入頻率不是一個很好的注意。請考慮一下:電台A在台南跟高雄之間,C5跟C6都能夠聽到他,但他比較靠近台南。他呼叫,然後電台B從南高雄回答,所以只有C6聽得到電台B。請問,電台A會不會聽到電台B的回答?

你當然可以說”沒有問題!我們把所有的中繼器連接,還接到echolink,這樣每個中繼器會發出每個中繼器輸入頻率的信號。“而我一樣只會搖頭。這是緊急通訊要用的,對不對?那,你好像不會期待太多人需要用到。因為,這樣看起來,全台灣同時只有一個人可以講。啊,你也可以讓所有中繼器分開運作?不過,我們還是有一個問題::輸出頻率都一樣。所以,如果南部有意外,而台南的電台要問高雄的情況,他好像不用問,因為C5不讓他聽到C6的信號。為什麼一個非常簡單,非常基本而非常邏輯的解決方法在台灣好像這麼難用:給每個中繼器自己的輸入跟輸出頻率!

這還有另外一個好處:當一個歐洲人我習慣在各頻帶有按照規劃分配頻率的中繼器。在歐洲使用中繼器很方便。在台灣:超麻煩。為什麼?因為輸入頻率跟輸出頻率的區別不一定。你沒有發現你的VHF/UHF收發機可以設定一個shift frequency?那是中繼器用的!我只要設定一次就好,之後只要叫收發機用這個shift就可以。我甚至已經多幾年可以叫它自動地使用這個shift,如果我在中繼器頻率範圍內。但在台灣我為了每一台中繼器需要分開設定輸入跟輸出頻率 - 或者要先計算那兩個頻率差多少,然後分開設定shift。

這很無聊,知道嗎?所以,請問,有沒有辦法做一點規劃,用同一個shift,而讓所有中繼器不會互相干擾 - 不管是輸入或輸出頻率?這會不會太難?希望有人會聽…

Wow, now the spam is really rolling. I always had the occasional spam user registration once in a while, but the last two days it seems there were about 200(!) registrations, and all under the name "girl, girl", many with an e-mail address that contained some Chinese name, so I guess the author of the software behind all this is of Chinese descend.

If this goes on, I will probably close down registration completely, at least for a while...

我真想知道規劃我現在住的地方的電線的人到底有想什麼。我真希望他必須一輩子住在一棟所有插座都掛在一個10A保險絲的房子。

我今天有換一個插座,因為昨天烤麵包的時候發現它變了比較溫暖。換之前當然要找哪一個breaker負責這個線路,而那時候我突然發現幾乎所有的插座都接到一個20A的breaker而已!唯一看到不一樣的地方是廚房一個插座,但那邊沒有辦法放烤箱或微波爐,因為只有大概放一個盤子的空間。目前連冰箱都在同一個線路……

光我的烤箱已經是1200W,微波爐800W。我不知道冰箱是多少,但是應該不只有200W。而因為台灣只用110V,這樣就是20A。而且,電腦跟熨斗(這又是1000W……)也在一樣的線路……所有燈也掛在20A,但是至少是不同線路。

我猜至少洗衣機有自己的線路。這種事情真會加強人家對房子設計規劃能力的信任……

And again. And again. And again...

May I rant? I think I may, this is my site after all. Having been an interpreter in a former life, I have been trained to use standard tongue in any language I use. Dialects may be understood, but they make communication harder. And what is hard for human beings may be impossible for computers - deviations from standards usually result in errors. This is one reason why I am a very strong opponent of any website or networked application that is "made for IE".

Why is it necessary to write HTML, Javascript or CSS especially for the one browser that violates or ignores all kinds of standards? Why not write standard code and accept that IE is not able to display a few things correctly? Other browsers will be able to...

But this is still nothing. Other browsers have learned to at least disguise themselves as Internet Explorer, so users do not need to worry about funny error messages, like asking you to upgrade your 2011 browser to one from 2001 ... So what can you do to throw them out? Simple: Use ActiveX!

In case you do not know: An ActiveX element is a piece of software that a website installs on your computer - to access that website. Indeed, for some sites it is not sufficient to use the Internet Explorer to access that site, you still need ActiveX on top of it! Security issues? Pah...

If you have been browsing the web for a while, using all kinds of browsers on different operating systems, you may ask now why someone would need ActiveX to access a website when you and me can do so without. Well, fasten your seatbelt: My current employer purchased some kind of collaboration software written in Java and running on a Windows machine. That site requires (in 2011) "IE6 or higher", according to the error message I get with any other browser than IE. But the best...

There is a window for a "message center" on the site. I never saw anything inside other than a question mark when I used Firefox/Chrome on Windows. Then I used IE and was surprised to see - text. Yes, those experts managed to require ActiveX to display text on a website! I am completely flabbergasted by so much professional expertise...

Since I complained, the software company will send someone next week to try and "enlighten" me. I am looking forward to his futile attempts at answering my questions...
