I found code for modify RF_R49 and RF_R50 in AsicGetAutoArgcOffset() in vendor driver (called by AsicAdjustTxPower, called by MlmePeriodicExec). Name of called function RT30xxReadRFRegister(pAd, RF_R49, &RFValue) and RT30xxWriteRFRegister(pAd, RF_R49, RFValue) make me stuppid, and I can't see if (IS_RT5392(pAd)) above. But RT3070 based module WN8020 start work correctly with this modification. > I'm using 2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO > as source, are you using some other vendor driver sources ? Yes. I use this vendor source. > Also could you please elaborate how did you measure TX power? I use ZX47-40-S+ power detector from http://www.minicircuits.com/ connected to WN8020 antenna output, and 1K load at output of power detector connected to osciloscope. Direct pdf datasheet link http://217.34.103.131/pdfs/ZX47-40+.pdf Os X with Ralink driver show about 580mV on 1K load (about 15dBm) regardless txpower setup in Ralink wireless utility. Vanilla 3.8.2 driver show 860mV (about 4dBm) if tx power set to 20dBm with iwconfig wlan0 txpower 20 and 980mV(0dBm) if tx power set to zero with iwconfig wlan0 txpower 0. Patched driver show about 580mV (15dBm) after setup 20dBm txpower with iwconfig wlan0 txpower 20, and about 980mV(0dBm) if tx power set to zero with iwconfig wlan0 txpower 0. I send screenshorts from osciloscpe directly for you some later. Vendor driver show 580mV (15dBm) if write TxPower=99 into RT2800STA.dat config file, and 980mV(0dBm) if TxPower set to 100 or 0 in RT2800STA.dat. All other value TxPower placed in this gate. Unfortunately, no resons to init RF49 in vanilla wireless code. At this moment I got critical analyse for my code, and still thinking. >> RT30xxWriteRFRegister(pAd, RF_R17, RFValue); >> But 0x5f for RF_R17...
