CS580 has advantages over Whistler
I have been using the CS580 in the car with a mobile antenna and it demonstrates better sensitivity and faster capture time than my Whistler WS-1088 for DMR. This is probably because of the limited frequency range of the radio. I like its ability to scan DMR for a limited portion of the spectrum and the fact that the radio will display the DMR parameters when it finds a transmission. Since some DMR commercial users are not listed on this site yet or have migrated from analog to DMR, the CS580 is great to locate these sites. I can then look up the frequency on the FCC database and document this info. I am not aware of any other radio that will scan for DMR. Being able to to change DMR info from the front panel is also a unique feature.
It is interesting that when a receive contact folder contains a contact (i.e. a talkgroup) that is present in another receive contact folder, the CS580 display may indicate the channel related to the first folder.
Another nice thing about this radio is that it can be used as a DMR/analog scanner with a price much lower than Whistler's or Uniden's, at least for the growing UHF segment.
