Impressive audio output volume, long-lasting power, plenty of memory channels, rugged construction, rich in analog features – the T70A offers practical 2m/70cm dual band operation and ruggedness, updated for today's ham radio enthusiasts.

700mW loud audio

The IC-T70A HD users a BTL (bridge-tied load) amplifier that doubles the audio output. Every ham knows that power = current × voltage. The T70A’s BTL increases the audio output by doubling the voltage delivered to the speaker. The 36mm large speaker delivers 700mW of loud and intelligible audio* even in noisy environments.
*Typical value using internal speaker.

Long lasting battery life

Get 5W of power on VHF and UHF in a small, lightweight package. Get up to 19 hours* of operating time with the T70A HD power version, which includes a Li-ion battery pack (BP-265) and rapid charger (BC-193). All that power comes is an easy to hold and use size – not too big, not too small. The T70A Sport version, ideal for long storage or quick back-up, features an AA alkaline battery case instead of a charger/rechargeable battery pack.
* Typical value using internal speaker.

External DC power jack

An external DC power jack allows for operation and charge when used with an external DC power supply (10-16V DC).*
The BP-265 cannot be charged using the external DC power jack.

A total of 302 memory channels

With 302 alphanumeric memory channels, including 50 band edges and 2 call channels, the IC-T70A HD gives you flexible scanning lists. With a maximum of 26 memory banks*, you can pick and choose the desired banks for scanning from the 250 memories.
Up to 100 channels per bank.


CTCSS and DTCS tone codes provide quiet stand-by and allow you to use tone-access repeaters. Pocket beep alerts you when a matching tone frequency is received. Tone scan detects the subaudible tone that is used for repeater access.

Internal VOX function

The IC-T70A HD has an internal VOX (Voice Operated Transmit) function for convenient hands-free operation when used with a compatible optional headset and plug adapter cable. Also, the VOX level and VOX delay time are adjustable.

IP54 and MIL-STD 810 rugged construction

Dust protection and water-resistance equivalent to IP54 provides reliable operation for practical outdoor operation. The IC-T70A HD tested to and passed MIL-STD 810 environmental tests.

Also available: T70A SPORT featuring AA alkaline power

aa alkaline batteriesPerfect for long shelf life use, such as emergency kits. Same output power (5.5/2.5 or 0.5 Watt selectable) as the standard T70A HD. The T70A SPORT comes with an alkaline tray that will hold 6 AA size batteries* . No charger required.
*Batteries are not included.

The T70A SPORT radio meets the same military specs and IP tests as the regular T70A HD radio.

Make the T70A SPORT part of your amateur radio communications plan, for emergency or everyday use.
