Modified on Fri, 03 Mar 2023 at 10:48 AM

On May 22, 2015, Icom issued a firmware upgrade for the ID-5100 radio. The RT Systems programmer was modified within days of that upgrade to address all the changes. One change in particular that could be of concern to a new user is that of Tones.


The original version of the radio had the following Tone Modes:

Tone - transmit only to the repeater

TSQL - Transmit and Receive of the same tone

TSQL R - Reverse Tone function

DTCS - DCS code transmit and receive

DTCS R - Reverse DCS function.


In the E3 version of the radio Tone Modes were expanded to include:

Tone - transmit only to the repeater

TSQL - Transmit and Receive of the same tone

TSQL R - Reverse Tone function

DTCS - DCS code transmit and receive

DTCS R - Reverse DCS function.

D Code - DCS transmit only

D Tone - DCS transmit / CTCSS receive

T DCS - CTCSS transmit / DCS receive

Split Tone - Different CTCSS frequencies for each transmit and receive.


The "Reverse" tone function is explained in detail in the operating manual for the radio.
