It is almost like Christmas with all the new gear being introduced by Icom. After Icom received rave reviews on the ID-31A, and hearing how being dual band would be the perfect D-STAR portable, we’re excited to introduce Icom’s latest D-STAR portable: the ID-51A Dual Band Handheld.

Compact dual bander
The 26.4mm slim body contains 5W output, VHF/UHF dual bands, a rich D-STAR and integrated GPS receiver feature set. 

Independent AM/FM receiver
FM and AM broadcast stations can be monitored while using the dualwatch function for monitoring VHF/UHF ham bands. When a ham band signal is received, the broadcast station is automatically muted.

Automatic position reply function (DV mode)
When receiving a call addressed to your call sign, this function automatically transmits your current position information. If the radio loses the GPS signal, the last position information with date and time information
can be sent. 

V/V, U/U, V/U Dualwatch
The ID-51A/E receives two bands simultaneously including in the same band*.
*When DV modes are set in main and sub bands, sub band audio will be muted. 

Other features

  • TX voice memory (1 channel, 60 seconds) for repeated calls
  • Voice synthesizer function announces frequency, mode and call sign
  • Voice memory function records incoming and outgoing calls and can be used as a voice recorder
