2GB of disk space? I would have killed for that as a kid.

Oh, also: Norton Commander 5.51, the last release that ever came out for DOS (1998).

突發奇想:
智慧型手機能不能像一般手持無線電一樣,頂上有個 SMA 接頭?這樣就可以外接奇怪的天線了,搞不好還能用八木天線。

我自製了一隻場強錶 (Field Strength Meter),雖然精準度肯定是沒有的,但靈敏度還可以。
不過因為二極體是 1N60P,所以頻率大概到 VHF 而已,到了 UHF 頻段靈敏度就會大幅降低。

有點想玩 MMDVM,不過設備價格有點超過預算了……

之前一直在懷疑 FT-991A 的 VHF/UHF Power Amplifier 部分為什麼可以只使用一個電晶體 (RD70HUF2),直到我剛剛反應過來這玩意其實是兩顆 MOSFET 合在一起。

Note to self, sanity check these kinds of cheaply made modules before connecting them up. I only found out this SD card reader's power rails were shorted out AFTER putting it in circuit. 😬​

After a visual inspection I guess I found the fault (C2)...

昨晚在朋友家玩短波,然後還做好了這組雙槳 (Dual-Paddle) 電鍵。
