On which operating systems are the Codan software products supported?

The operating systems supported are dependent on the software product. Codan software generally supports Microsoft Windows® XP and higher. However, please check your software product datasheet for specifications.

Do I need to update my HF radio’s firmware?

You don’t have to update your firmware, your radio will be fully operational without firmware updates. However, should Codan recommend a firmware update for any reason, the firmware upgrade can be easily completed using NSP / TPS software, or direct through USB stick (Envoy radio series). Firmware updates generally provide your radio with new capabilities, or may address software bug fixes.

For the Codan HF products that support “data”, what kind of data is this? How fast is it transmitted?

Codan provides a range of data options for different applications, with capability for messaging, email and chat. The data rates are generally between 75 bps and 9,600 bps (not including data compression), depending on channel conditions and the modem option you have installed.

Codan’s robust low rate modem, available as a software option in Envoy and Sentry-H 6120-BM products provides data throughput up to 2,400 bps (uncompressed) or 6,000 bps (compressed), and is a highly cost effective option. Codan also provides full MIL-STD modem This provides data according to MIL-STD-188-110A & B, with rates up to 9,600 bps.

When used with an independent sideband capable radio, the rate can be up to 19,200 bps. All data capability will depend on channel conditions.
