Thanks

Why would you need a pre-selector? From the blurb at "IC-R8600 : Receiver / Scanner Base Station - Icom UK" it would appear that the front end of the receiver has plenty of filtering.....

The IC-R8600 has 11 discrete RF bandpass filters in the HF bands and 13 bandpass filters in the VHF/UHF bands. To prevent overflow, only the intended signal is passed, while any out of range strong interference signals are rejected. The IC-R8600 provides +30 dBm IP3 and 105 dB dynamic range at 14.1 MHz. IP3 performance is +10 dBm at 144 MHz and 0 dBm at 440 MHz.
