AM BROADCAST SENSITIVITYThe R-5000 has excellent sensitivity in the HF band. The sensitivity in the AM broadcastband is acceptable for most. If you are a hard-core AM broadcast DXer, you can increasethe sensitivity in this band slightly. The input filter for this band has an attenuator on itsoutput consisting of R9, R10 and R11. Cutting either R9 or R11 will decrease the amount ofattenuation and increase the gain. Be aware that this increase in gain can have a negativeeffect on strong signal levels in urban areas. A nearby AM broadcaster will have a tendencyto overload the front end of the radio, which will result in interference in the receiver. Thestrong AM broadcast signal will not be properly attenuated and will punch its way throughthe front end. This interference will block reception of weak signals and the nearby AMbroadcast signal could show up all across the band at various intervals blocking otherstations.6
