ICOM R-100 receiver
I have owned a ICOM R-100 (un-blocked) receiver for a little over eleven years, purchased new along with it's matching AC supply. I have only used it my at home, never mobile, and have had very good luck with it. However, I do NOT use it as a scanner, just listening to a local six meter repeater and sometimes my local FD. The reason being is that it scans slow and when it changes frequency ranges there are internal relays that switch on and off, much like in the R7000 and R7100.
The radio has all kinds of features, a timer, display dimmer, a preamp/attenuator, N-connector for high frequncies, etc. It is very well built and is heavy, all in metal housing. Very sensitive on low band and high band and UHF, I have never used on 800Mhz or shortwave either.
I will say that it is more sensitive than most Bearcat scanners that I own. You can checkout what others say at :

If you have other questions, please advise.
Take care, Rich
