As stated in a listThe comment about the dBuV reading is incorrect. The RSSI readings are referred to the pins of the chip, which are the inputs to the LNA. In the Tecsun radios operating in the MW band, this is also the voltage across the loopstick. In SW bands, the Tecsun ULRs use a preamp/LNA on the circuit board between the whip antenna and the Si4734. In that case, the RSSI readings reflect the signal at the output of Tecsun's external LNA.
Thanks for the complements about the Si4734. While Tecsun and others emphasize the chip's DSP features in marketing, the Si4734's performance is also enabled by considerable analog Kung Fu.
