The FLEX-8000/6600/6400 Extended Transmit Module (ETM) is a supplementary bandpass filter module that can be user-installed in a FLEX-8000, FLEX-6600 and FLEX-6400 series radios, allowing for transmission outside of the IARU-designated amateur radio bands.
Amateur service customers needing the ability to transmit on frequencies other than those allocated to amateur service will require the following:
- FlexRadio 8400(M), 8600(M), FLEX-6600(M) or FLEX-6400(M) radio
- Extended Transmit Module – factory or user installable.
- A radio-specific TURF file (firmware unlock key) is provided at no charge.
To obtain a TURF file, US and Canadian amateur customers must provide one of the following current and valid credentials:
- MARS, SHARES, CAP, USCGA – US only
- CFARS – Canada
International customers requiring a TURF file should contact their FlexRadio regional distributor for assistance.
Once the Extended Transmit Module is installed, a TURF file is required to activate the module and can be provided by our technical support team via a HelpDesk support ticket.
