Transition from 2 x IC-7610 with 2 x SPE 2K-FA to 1 x FLEX 6600M

Re: Transition from 2 x IC-7610 with 2 x SPE 2K-FA to 1 x FLEX 6600M


The current setup is as follows:

  • 2 x IC-7610
  • 2 x SPE 2K-FA
  • Microham U2R audio interface
  • Array Solutions SO2R kit (1 X 8 Pack antenna switch, 2 x FilterMax IV BPFs, 2 x SM-8 Shack Masters)
  • Steppir DB36 (RUN)
  • Steppor DB18 (MULT)

I want to swap the 2 x IC-7610 for a single Flex 6600M.

What cables do I need for a seamless swap ?

    PS I want to swap the 2 x IC-7610 for a single Flex 6600M to run it with my 2 x SPE 2K-FAs.

    My 2 cents:

    • sell the Microham as you don't need it
    • You can send band data from back of the 6600M to each Steppir dedicated to each SCU of the radio
    • Dedicate the SPE's, one to each antenna port of the radio and use TX1 on 1 amp and TX2 to the other Amp
    • Sell the Array solutions stuff including filters and replace them with 1 Antenna Genius 2x8.

    That's off the top of my head.

    But, the short story it is a lot simpler, a lot less equipment and a lot less RFI concerns.

    As Mike pointed out, you can use two USB to serial cables from the radio to each SteppIR controller for frequency information.

    Use two Denkovi or SainSmart USB 8 relay boards plugged into radio and set up as bit cables. Set each to follow Ant 1 and Ant 2 to give band relays for the Filter Max IV BPFs.

    Also two USB to serial CAT cables for each amp to radio to follow TX antenna 1 and 2.

    You will need a USB powered hub as the radio only has two USB ports.

    Here is the Flex USB cable interface guide https://edge.flexradio.com/www/uploads/20200818184951/USB-Cable-Interface-Guide.pdf

    You should be able to eliminate the two 7610s, the Microham U2R, and Array solutions equipment, except the BPFs.

    That would be my recommendation.

    Just a FYI for those who want to run 6 antennas with full QRO system from SPE ☺️

    I set mine up using a log periodic for 10 - 30mhz and resonant antennas for all other bands.

    2 USB from pc to SPE's. Flex 6700 talks via cat Y cable to both spe. Also running SPE remote antenna system (AMB-02) for 6 antenna's.

    Works perfectly on every band and the whole system is monitored/controlled from my pc. I never touch the radio or any other part of the setup.

    1 coax cable from the shack going out through my window is all i have. Nothing else required.

    I also have a 6600 which has 1 coax cable through my window going to multi band vertical which gives me full SOR2 on all bands whilst running QRO.
