Does anybody own md380 and baofeng or gd77. I own both and did a test. Md380 has much worser rx reception than baofeng 1801 does. I did a research on uhf and vhf. On uhf it works more or less ok, but on vhf, its a really big difference. Any suggestions. Will be possible to calibrate it?

on VHF & UHF is roughly the same. Consider, what can you expect from a 150 dollar (end user!) device ?
There is not much room for quality control, or to produce equal precise specifications for each device. Unfortunately...
'calibration' is the term of adjusting a measurement info compared to a given standard: Example: scale/display shows 5 watt - measured output
on a calibrated watt meter is the same, if not, the display/scale must be adjusted accordingly, so it will be kind of 'calibrated' too.
Btw., I don't think sensitivity of a MD380 can be adjusted.

I did a research, had two rt3s and baofeng1801, all low budget... baofeng has better rx, rt3s lower reception, both ones. Tried with gd77, and also worser reception. I think that opposite sma might have sth to do with the reception... idk. I will make a video and post it for a comparison.
