Values shown are for Receiver A. See Table 1 for
additional measurements.
* Measurements are noise limited at the values shown.
On the left side of the case (when
facing front) you find the push-to-
talk button, a squelch-disabling
monitor button, and the power
on/off button. You can capture tiny
BMP images of the ID-50A screen
by enabling the capture function
and briefly tapping the power but-
ton.
And speaking of capturing images,
immediately below the power but-
ton resides the port for a microSD
memory card. Icom doesn't supply
a memory card with the ID-50A, but

they are available from many retail outlets. I happened to have a 32 GB
card on hand, and it worked perfectly. The card is used to store images
sent or received via D-STAR, as well as repeater lists, frequency memo-
ries, GPS logs, audio recordings, and more. By accessing the appropriate
menu setting, the ID-50A's memory card can function like an external hard
drive whenever you plug the radio's USB cable into your computer.
