Скачать или смотреть HF FULL BAND Mod. ver 2.5 & ver 5 INSTALL - UV-K5 Si4732 with BGA427 & BFU550AR LNAs

We install si4732 mod version 2.5 (version 3 if you are eager), also instructions apply for version 5. Difference between version 2.5 & version 5 is the way BGA427 LNA is done, the latter uses second application from datasheet and provides 22 dB of amplification, whereas ver 2.5 provides only 18.5 dB. There are 4 ways to install this mod, 1) single antenna, 2) dual antenna, 3) discreet antenna, and 4) single antenna with dual LNA's. We are going to try and test all 4. We also going to install (optionally if you wish) improved LNA, BFU550AR.
