中部哪買線性電源供應器.....

鵝因為有事回彰化一陣子,帶IC-706回來當接收機,才發現隨身帶的SMPS根本是特大號雜訊產生器,只要一接上天線,0.03-60MHz永遠是S9,請問中部哪裡可以買到DC12V 3-5A的線性式power supply啊(不須要可調式或太大電流的,因為沒打算玩TX,而且也沒打算帶回北部),還請友台指點一下了....

I knew a guy who charged batteries on cheap electricity at night and powered them with RIG during the day. That still solar panels were only on Russian satellites and Japanese calculators.

我認識一個人，他晚上用便宜的電給電池充電，白天用 RIG 給電池供電。 那個靜止的太陽能電池板只在俄羅斯衛星和日本計算器上。

Thanks,用電池還有個附加的好處就是可以野架,不過電池容量有限,充電又頗耗時,這點還是不如直接用線性式電供就是了....

Hi, a linear power supply needs an expensive and heavy transformer and must be well made so that it doesn't get too hot. Even so, the operation is quite uneconomical.
Nowadays, battery operation is offered, charged from the mains by a cheap switching power supply outside the operating hours or by the sun.

嗨，線性電源需要昂貴且笨重的變壓器，並且必須製作精良，以免過熱。 即便如此，該操作還是相當不經濟的。
如今，提供電池供電，在工作時間以外或由太陽通過廉價的開關電源從主電源充電。
