11月7号在hallocq上看到一关于710扩频的帖子（https://www.hellocq.net/forum/simple/?t376088.html），翌日便开始操作，结果是成功的。至于标题所言“无意义的折腾”......我买的是国行，能用的都能用，不用瞎整，但不能用的怎么整都不能用。对于日版，又无法扩频，故有“无意义的折腾”。其操作过程，写了一个记录，直接贴上吧（其实是懒的打字），字写的丑，求见谅。[upl-image-preview uuid=b67b941a-dda2-4695-a552-bce26a02be16 url=https://storage.hamcq.cn/2025-12-25/1766686751-778379-20251226020728-134-96.jpg alt={TEXT?}] [upl-image-preview uuid=b7a0bb2c-c36b-4ac3-9bd3-7207f6f8102d url=https://storage.hamcq.cn/2025-12-25/1766686752-742527-20251226020723-133-96.jpg alt={TEXT?}] [upl-image-preview uuid=e25f0f9d-1030-41f0-89b9-8c96f4e56dfe url=https://storage.hamcq.cn/2025-12-25/1766686751-495582-20251226020733-135-96.jpg alt={TEXT?}] [upl-image-preview uuid=aa6379b0-f46f-4837-b9cd-6a9d9fa32585 url=https://storage.hamcq.cn/2025-12-25/1766686774-22130-20251108142107-109-96.jpg alt={TEXT?}] [upl-image-preview uuid=39b70230-372c-41a5-a3c5-a9f41c156ae5 url=https://storage.hamcq.cn/2025-12-25/1766686784-213008-20251108212534-111-96.jpg alt={TEXT?}]

官网参数：频率范围: 1.8MHz - 29.699999MHz (业余频段) 50MHz - 53.999999MHz (业余频段) 扩频后多的是那些非业余频段吗？能听到什么呢？合规最重要

是增加了UV段吗，如果增加了这两个段那就可以多用途了

@"debain"#p91390 没有扩增uv段，只到54兆

@"bh1cqz"#p91372 都是非业余段，反正就瞎折腾，能听什么呢？

字写得丑是吧，那我不得跳了

扩频后70MHz频段也有很小的一个频率范围也是能发射的

@"BI1KXE"#p91489 哦吼，一直没发现感谢大佬指点

Official specifications:
Frequency range: 1.8 MHz - 29.699999 MHz (Amateur band) 50 MHz - 53.999999 MHz (Amateur band)
Are most of the channels available after wideband operation in non-amateur frequency bands? What can I hear? Compliance is the most important thing.

BG5VNL

bh1cqz They are all non-professional segments; anyway, it's just random noise, so there's nothing to hear.

debain

Does it also increase the UV segment? If both segments are increased, then it can be used for multiple purposes.

BG5VNL

debain No expansion to the UV segment; it stops at 54 MHz.

YofoaStudio

The handwriting is so bad, I can't possibly read it.

BI1KXE

Even within the 70 MHz band after frequency spreading, there's a very small frequency range that can be used for transmission.

BG5VNL

BI1KXE Oh my goodness, I didn't realize it was there all this time.
Thank you for pointing out the issue.
