请教大佬们一个问题，用两根IRF530 DIY短波功放工作电压是13.8V，待机电流0.2A。今天上午在14.27MHz ，SSB语音通联过程烧坏一次，更换IRF530后，自动天调显示发射功率35瓦时，最大电流2.7A，正常么？？？测试用短波电台是X6100，5瓦。有个情况说明一下，之前同样发射35瓦需要9A，今天更换IRF530后就这样了。

@"BG5CJI"#p51202 不正常，要不看下跳过功放，电台直接发射功率、电流多少

不正常，13.8*2.7=37.26w，射频功率35w，AB类放大器效率不会这么高的，E类功放效率也没这么高

14.27 MHz SSB transmission, operating voltage 13.8 V, is the peak current of 2.7 A too low?

I have a question for experienced individuals: When using two IRF530s to build a shortwave amplifier, the operating voltage is 13.8V and the standby current is 0.2A.
This morning, at 14.27 MHz, the SSB voice communication process failed once. After replacing the IRF530, the automatic antenna tuning display showed an output power of 35 watts and a maximum current of 2.7A. Is this normal?
The test shortwave radio is an X6100, with a power output of 5 watts.
Just to clarify, previously, achieving 35 watts required 9A. However, after replacing the IRF530, it now only requires that amount.

BG5CJI Abnormal. Or, check the bypass amplifier and the radio's direct transmission power and current.
