I still think 15W PEP is not generous enough. 25W might be a sweet spot.

ICOM: Not always.

Questions about PEP power limit in Ham radio.

Rumors said the Chinese Government is planning to downgrade the PEP power limit from 100W to 15W, this might be released in the mid of 2024.

Besides all administrative procedures, I wonder if 15W PEP is technically sufficient for HF ham radio.

I almost use digital all the time. Mostly FT8, followed by PSK31. Sometimes I use feldhell and SSTV.

From what I remembered (I didn't switch on my radio for the last 3 years), the digital mode is a bit more careless about how much power you use. And it feels wrong when everyone is QRP and suddenly you shoot 100W into the air. The analog mode is different, the more power you use, the less noise your decoder picks up.

I still feel uncomfortable with this downgrade of PEP power. I think it would be great to work in QRP, but 100W is an option when you need it.

@AmpBenzScientist The emulator from Google is not support bluetooth, said by documents. The camera on my laptop is crap and can't recognize any barcode

@error @Zoeyyyyy 查了一下，好像是利用漏洞做到的。比较关键的就是在an之前输入数据可以影响缓冲区指针的位置，然后借此覆盖掉显存就可以显示了（

@AmpBenzScientist Emulator is still a thing, but my app uses camera to scan barcode and Bluetooth to send data to thermal printer. Emulator can't achieve that...

First I have to figure out why my device is not recognized by adb.

Then I have to figure out why my app keeps crashing after I redeploy it after changing some code. Turns out it's android 11's optimization causing the problem. Disable it fixed the issue.

Then the logcat is not working. The ADB is fine, but just logcat showing the device offline. I cannot read any log from my code and I can only know what's going wrong by triggering the exception multiple times and hoping the system will show me the stacktrace.

And to make things worse, the json naming annotation stopped working. I told it the requestId field should be request_id in json but it just doesn't care. I literally make no change to the code, just copy and paste from the old one. WTF

Being rejected by HRs on job finding app is not that worse.
But writing android makes me want to die.

Despite some of the basic ideas are taught in high school, with the great explanation and visualisation, it's a good video to watch when you need to distract yourself from the anxiety of being unemployed.
