Painted the Discone grey? Its buried in clouds???
What he really means is HF up to 30MHz allows you to select any of the three antenna inputs. Above 30MHz it defaults to the N connector and you have no choice.
Above 30 MHz, only my discone is selectable. below 30 MHz, only the wire is selectable.
Below 30MHz I can select one of three antenna inputs, above 30MHz it defaults to antenna 1. You can select different inputs via the FUNCTION button or when below 30Mhz under the mode icon it will show what antenna is selected and you can use the touch screen to change it.

Below 30 MHz you should be able to select any of the 3 antennas
I’ll post picture when I get back home in a few weeks.
Is your R8600 the US version receiver? Running the latest 1.35 firmware version?
All 3 antenna inputs become a user selectable option on all freqs below 30 MHz. At least both my 8600's allow me to choose any of the 3 Ant inputs when tuning below 30 MHz.
This is inline with what others have posted including the fact that when tuning 30 MHz and higher, only Ant 1 is used and cannot be changed.
I've never seen an 8600 that didn't allow the user to select any of the 3 antenna inputs when tuned below 30 MHz which is why I asked the question if yours is the US version or one of the other regions that may have the old analog AMPS cell band unblocked. I have no idea if the other regions models may limit which antenna input you can select below 30 MHz and I see no reason why they would have such a limitation really.
@bearcatrp: When tuned to a freq below 30 MHz. you should see the "ANT1" indicator to the left of the frequency display. Tap that to scroll thru the other connectors.
My 7000 was bought new from EEB in the 90s and it had the scan speed and delay mods as well as the remote control ( The controller was missing ). I like it, I'm a sucker for older Icoms but I am digging the 8600.
Also note that as you cross the internal bandpass filter selections below 30 MHz the antenna selections will change.
If you select for example ANT 2 from 1.6 MHz to 2.0 MHZ. The selection made above 2.0 MHz to 6.0 MHZ will change to what you selected for that band. Could be Ant 1,2, or 3. The setting will "stick". It will occur as bandpass filters are internally switched up to 30 MHZ.
I used to have a table showing the different filter ranges. Anyone?

Found it in the service manual.
B1 thru B10 should be the thresholds where antenna selections can be made below 30 MHz.

Good point.
Mine is the US version. Bought it from HRO.
My 8600 is being hammered by two (if not more) 2kW FM broadcast transmitters less than 3 miles away. 10dB of attenuation fixes it but holy crap. It's not a huge complaint about the 8600 but does anyone recommend a GOOD FM broadcast filter that doesn't nuke the bottom end (118MHz) of VHF air TOO much?
I think you want the MiniCircuits ZBSF-95+. Connectorized Band Stop Filter, 88-105 MHz | ZBSF-95-N+ | Mini-Circuits
Prcguy is right. I bought one after his recommendation a couple years ago. Works as advertised. Worth every penny.
Thank you kind sir. If you're ever in the Chicago area let me I'll buy you a beverage of your chosing.
Not normal here.
