Flex-6600M Power Amplifier and SCU

Hi. Would appreciate some help with the following queries regarding the FLEX-6000 SDRs.
1) Can the Flex-6000 transmitter be operated continuously for say 8 hours or is the transmitter designed for intermittent transmissions?
2) Can the SDR be set to transmit at any frequency in the HF band or is it restricted to the amateur bands in the relevant country?
3) Trying to understand the SCU concept. Do the SCUs allow direct digitisation of the whole HF band, i.e can the Bandpass filters be bypassed? Also is the wideband data accessible or does it go through receiver slices before being accessible?
Many thanks

    1. Broadcast mode. No. As it overheats it will start to shut down the transmitter power due to over heating based. It depends on the drive power you are using and the transmission mode.
    2. Amateur bands only unless you have a license to transmit outside the amateur bands and a Extended Transmit Filter Board. We will then provide the TURF file to extend your transmit limits.
    3. Each SCU receives from 30Khz to 54Mhz at 16 bits 100% of the time. The bandpass filters are bypassed as you set a VFO to receive outside the amateur bands.

    If you have a commercial operation you are looking into, then please email FlexRadio at sales@flexradio.com and we can discuss in more detail.
