我知道SSB的功率是动态的，但是我的IC705平均功率差不多两三瓦左右的样子，这正常吗.....（正常说话的音量，MIC GAIN在70左右，开了亚扩，FM，AM功率正常，在8～9瓦左右）

FM正常就说明基本没问题，如果还不太放心的话可以搞点FT8之类的恒包络信号发发看

我也有这个问题🤐🤐fm和ft8功率都正常，整机能到40w，一上ssb整机就很低我怀疑可能是因为手咪的问题？

@"FengziLeo"#p87112 大点声能解决98%的问题（

如果你想看到底用多少电流切FM。。如果你单纯的想看看SSB能用多少，请往死了喊~

MIC GAIN调整到50%，语音压缩开到3以上，按下ptt时喊的时候观察下ALC

SSB声音和功率有关系如果不说话你SSB功率会很低如果单测试可以用CW FSK FM模式检验功率

@"BI1RRE"#p87144 是按照说明书上面调的，应该是没问题，我大声点喊，能喊到5到6瓦

@"BG5BNW"#p87147 这个我明白，就是不太理解，为什么功率这么低？

@"BG2EFX"#p87136 谢谢，主要是我最近打算给705加功放，才买了一个功率驻波计，有了这玩意儿以后，我才知道原来我的ssb功率这么低.....有点惊讶（以为至少有个5瓦），所以来发这个帖子看看大家是不是都有这种情况？

QRP radio SSB power issues

Oh oh oh_{Careless in understanding the question.}~_{I just saw the original poster mention that they have already started using "Ya Kuo".}

The most important thing in SSB testing is to keep shouting.😆

BD4WCL

BG2GFC I thought that was how it worked with my 705.😂Surprisingly, all QRPs were like this.

BD4WCL

Experts, it seems my equipment is indeed malfunctioning. The FM output is only 9.03W, far below the expected 10W, but I don't think it's a problem with the amplifier itself. What could be causing this?

BG2EFX

BD4WCL

Simulate a load and then try FM again.

BG7NQF

BD4WCL 9W, 10W... roughly speaking... doesn't qualify as "far below"

BD4WCL

Should I enter repair mode and adjust something? (I'm not sure how to do it; could you please show me?)

BD4WCL

BG2EFX Ugh, there's no dummy load available... just one open-ended cable.

BH9FPK

SSB, shouted loudly

BG7NQF

External power meter: If there's a PEP switch, please turn it on... It will detect and display the peak envelope power.
Furthermore, the differences between 5-6W and 8-9W are only 2 dB. On the receiver's specifications, there might be a difference of just one S number, which isn't significant!

BD4WCL

BG7NQF The main problem is that the amplifier isn't working properly. It's not outputting enough power, and I estimate that if it could output 9 watts, it would need to output around 15W more. I suspect my power meter is miscalibrated, but I don't know how to calibrate it... Anyway, as long as there are no further issues, I'll continue using it.🤣

I'm looking for a vocal training class.

BD6OC

A great effort can achieve remarkable results.

BG7NQF

BD4WCL Haha, yes, I'm using it even though there are no bugs yet. The difference of about 15W after pushing PA isn't a big problem. The difference between 100W and 85W is smaller...

An older Motorola Panda phone was recommended by a friend named Ham.
