This looks like a neat little toy to have. One day I do hope to purchase an ICOM rig with the D-Star capabilities. At the moment there is a D-Star Repeater in my area but I am unsure how much activity it receives. One day I may listen online. If you are interested in listening to DSTAR audio feeds via the internet, then you have two options:
Listen direct on my server at http://radio1.ham-radio- op.net:9008 or via the Radio Reference Web Site at http://www.radioreference.com/apps/audio/? ctid=321 Users on Radio Reference need to scroll to bottom of page then click on the speaker icon next to the Dstar feed name.
Back to the ID-880;
Icom is pleased to announce the debut of the ID-E880 mobile VHF/UHF dual-band, D-Star transceiver. The ID-E880 is designed to be easy to use and contain a new ‘DV mode’ feature which allows the operator to access D-Star repeaters in just two steps. The ID-E880 mobile is the successor to the ID-800H mobile transceiver and retains many of the features of its predecessor including switchable dual-band capability, detachable controller and 50W power output. The usability of the ID-E880 has been improved with a larger LCD display and a high speed scan capability of up to 50 channels a second. The ID-E880 is ideal for a range of users including foundation licensees, anyone new to D-Star and Ham organizations such as Ray-net that are looking for a simple GPS position reporting system.

HOW TO READ PROPAGATION NUMBERS
The A index [ LOW is GOOD ]
- 1 to 6 is BEST
- 7 to 9 is OK
- 11 or more is BAD
Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.
A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
SFI index [ HIGH is GOOD ]
- 70 NOT GOOD
- 80 GOOD
- 90 BETTER
- 100+ BEST
The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.
Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.
K index [ LOW is GOOD ]
- 0 or 1 is BEST
- 2 is OK
- 3 or more is BAD
- 5 is VERY VERY BAD
The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.
A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
