I liked it, the only thing I had against it was it's slow scan speed (I ran it from a computer, it could only do about 22 channels a second, something like that).
I guess that's why they are not scanners and are communications receivers. Many communications receivers today do have scanning functions but those functions are usually very basic and limited compared to an actual scanner.
With that, I also use communications receivers in scan mode myself regardless of the slow scan speed. I'm usually only checking a handful of frequencies or a small limit search that is not very wide between the lower and upper frequencies. So the slow scan speed does not really bother me much. If I find some active signals on an Icom receiver, I'll usually add them into a bank or favorites list on a Uniden or GRE providing the Uniden or GRE models even receive the signal.
I use an R7000, R8500, two R8600's and an R9000. All of them have great performance over a scanner for analog signals.
I do like the digital features the 8600 offers but it's a shame Icom won't budge on adding DMR into their receivers.
Who knows but maybe some day, Icom and others that still make communications receivers will actually support trunking systems and be able to follow them like a scanner!
