FM Band Scan in Bucharest NXP TEF6686 ( vertical antenna connected directly without splitter ) Bonus FM DX Test NXP TEF6686 vs ONKYO T 4670 on Z Rock 106 MHz Razgrad in Bucharest ( same antenna passed through a 2 way splitter checked for symmetry attenuation ) FM DX Test ONKYO T-4670 vs NXP TEF6686 on DENS FM Braila in Bucharest ( same antenna passed through a 2 way splitter checked for symmetry attenuation ) I have tested several types of modules with TEF668X, bought or recovered from android car platforms, but same results. The modified Onkyo, by far, rules the game on extreme DX !!!
