10W算不算QRP，15w呢另这俩是不是都仅适合野架，城市小区楼顶底噪真的无解？

理论上不算QRP 平时家用选G90，X6100我只推荐一种情况买，就是要全国各地到处飞拎着它方便。剩下的散热是个问题，特别长时间FT8之后。

@"BG2KAJ"#p37851 反正G90N家里用，感觉底噪较高，也没个降噪啥的，基本在家吃灰。

不太推荐协谷机器可以考虑FT-710 体积并不大用背包背着即可电池可以参考我发的帖子 ft710的电源电压范围很宽 M哥有个视频10V电压都有90W+的输出功率完全可以榨干4串磷酸铁锂的容量天线用M-130a自动调谐用三脚架支起来

推荐G90S，20瓦比10瓦多3dB

@"BG2KAJ"#p37851 我也在面临这个选择，请问有散热问题的是G90N还是X6100？

@"[未知用户]"#p37892 我只提X6100,6100散热不好是老生常谈了，大家都遇到了

有个方案，买个二手G90，玩玩就出掉，也不会亏什么。

For a beginner who occasionally takes short trips for field use and also uses it at home, if I have to choose between the G90N and X6100, and I want to cover SSB, FT8, and CW, what would you recommend?

Is 10W considered QRP? What about 15W?

Also, are both of these only suitable for outdoor use, or is it truly impossible to eliminate noise from rooftop installations in urban residential areas?

BG2KAJ

Theoretically, it doesn't count as QRP.
For everyday use, I recommend the G90. I only recommend buying the X6100 if you specifically need to travel around and carry it with you frequently. However, its cooling performance is a problem, especially after extended FT8 sessions.

Hangying

BG2KAJ Makes sense.

BG7NOD

BG2KAJ Anyway, I'm using the G90N at home, and I find that it produces a lot of background noise. There's also no noise-canceling feature, so it basically just picks up ambient sounds.

BG2KAJ I am also facing this choice. Which one, the G90N or the X6100, has more cooling issues?

BI4PMQ

BG2KAJ I bought the 705 because I needed to travel across the country, and a larger machine at home would have been more suitable.

I don't recommend XieGu equipment. Consider the FT-710; it's not very large and can be carried in a backpack. You can refer to my previous post for information on the power supply voltage range of the FT-710, which is quite wide. Brother M has a video showing that with a 10V input, you can achieve over 90W of output power, allowing you to fully utilize the capacity of four series of lithium iron phosphate batteries. For the antenna, use the M-130a and mount it on a tripod.

BD8DFK

I recommend the G90S; it's 3 dB louder than the 10W version at 20W.

BA3QU

BD8DFK 但是20瓦是需要在工信部申请执照，而且需要C类操作证书。

qrp refers to transmitters with a power output of 5 watts or less.

BG2KAJ

[未知用户] I'm only mentioning the X6100; the poor cooling performance of the X6100 is a common issue that many people have experienced.

Bg2gKg

Thank you.

BG7NOD

There's a plan: buy a used G90, play with it for a while, and then sell it. It won't be a loss.

[未知用户] +1 I currently have 710 pieces of chewing gum, a 10AH battery, a 5.6-inch pull handle GP, and 10 meters of 50-3 cable. Everything fits in one backpack. I can also buy a waterproof box to use as a desk.

If I operate at a normal 100W output, and use a 10Ah battery, how long will it last?

BA7LCA

pmxlbt I used GPT to calculate that at a voltage of 13.8V, receiving a signal for four half-cycles would be sufficient. With a continuous transmission of 100W, it could operate for 28 minutes. However, the actual operating time will depend on when I receive the battery.

BI1LWR

If you have a budget, I recommend the 705.
The X6100 only supports wired connections for phones, but it can easily interfere with phone signals, making wireless use essentially impossible.

Alternatively, using FT8 to connect wirelessly with a 705 mobile phone can be convenient.

For beginners, I recommend a 100-watt solar panel. Honestly...
Otherwise, it's easy to become withdrawn, especially when using SSB.

BG2EFX 工信部的坑：新B 15W，新C 100W估计就不会问这问题了

When someone refers to a "100W beginner radio," are they referring to a C-band beginner radio?😂
