BCD Connect to PGXL TGXL AGXL Chain

I have a FTDX101MP that I am trying to set up with the PGXL, TGXL, and AGXL. Where in this "chain" do I connect the band data cable to Port B so all three devices get the correct band info.

Also, any word as to when the CAT functions for the 101MP will be added to the three devices as is already stated in all the manuals.

    This is a good question and it shows the limitation of OEM radios to control multiple devices.

    To the best of my knowledge, the AG line does not really have a chaining function, so you can only control one device. The PGXL and TGXL will RF sense, so they can run on their own if required. The AG does require band logic, so that is the first thing would be to connect the AG to the FTdx101MP.

    You may want to email 403A support and ask them if they can recommend a solution. [email protected] They are a pretty resourceful bunch.

    Some ideas that you might consider.

    • Can the FTdx101dxMP support multiple devices on their BCD line? It is possible that all the inputs are high impedance, so this might work. You may want to check with Yaesu.
    • If not, then you will require some sort of multiport BCD Splitter. Easy enough to build and I have no idea if there is one manufactured off the shelf. Possibly MicroHam or Top Ten devices
    • You could do it in Node-Red by having a NR client listening to the radio frequency and then sharing it with other devices. It depends on how handy you are.

    73 for now

    Thanks Mike,

    That's where I started...got the AG working with the MP, so it changes antennas with the band changes.

    Started working with the PGXL and TGXL to get them to RF sense, but thunderstorms in the area, so had to pull the plug.
