Picture4是一种使用esp系列的远程控制电容式变频小环天线吗？效果怎么样？

@"5Breeze"#p84312 是的，因为手动调谐人体的加入会影响环的谐振，所以加了步进电机通过iPhone控制。作者Colin VK2JCC a.k.a. Professor Portable

火腿的年龄结构哦跟国内一样

我超，COMMODORE 64！？好古早的电脑

@"BG4QBF"#p84417 我们还有更古早的电脑 Microbee，澳洲本土研发生产的嘿嘿 [俱乐部文章](https://www.mwrs.org.au/2025/10/02/sep-2025-lecture-resurrecting-vintage-computers-with-mal-vk2tmf/) [俱乐部讲座回放](https://www.youtube.com/watch?v=mtkR5FavQxE) [维基百科](https://en.wikipedia.org/wiki/MicroBee)

@"BG5VCU-VK2VCU-AK6CU"#p84477 好厉害，我最老的是laser310

@"BG4QBF"#p84576 哇，也是老物件！这类老的计算机就和电台一样，都有维修手册、原理图，坏了还能照着图纸尝试自己修复。

5Breeze

Is Picture4 a remote-controlled capacitive variable frequency small loop antenna using the ESP series? What are its performance characteristics?

BG5VCU-VK2VCU-AK6CU

5Breeze Yes, because manually adjusting the body's addition affects the ring's resonance, a stepper motor is used to control it via an iPhone.

The age structure of the ham is similar to that in China.

Wow, a Commodore 64! That's such an old computer.

BG5VCU-VK2VCU-AK6CU

BG4QBF We also have an even older computer, the Microbee, which was developed and manufactured locally in Australia.

BG5VCU-VK2VCU-AK6CU That's amazing! My oldest one is laser310.

BG5VCU-VK2VCU-AK6CU

BG4QBF Wow, it's a vintage piece! Just like old radios, these older computers have repair manuals and schematics. If they break, you can still try to fix them by following the diagrams.
