You asked about where the Band Data comes from.

I derived band data from the Flex Server "BCD" USB cable output. ?

Here is a link to the USB Cable Usage Guide, from Flex;

You can find my flow for the band decoder on my ?github in the?“Sub-Flows” folder, "Satellite Board” flow file.

I connected each output ?wire ?(Bit) of the USB cable to a unique GPIO pin on the Raspberry Pi. ? I then use this table to build a ?“decoder” using Boolen logic gates (reverse truth table) for each band. ?

Here is a map from the FTDI USB cable specification showing Bit versus wire color:

Finally, I got to use something I learned 50 years ago in college, building Boolean equations from?truth tables. ?The truth table is ?provided in the Flex USB Cable User Guide.

Here is a screenshot of the flow, with the 40M segment selected. ?It is a simple matter of using “AND” logic on the " X” "OR" "X-Not” pins. ?(X=1, X-Not=0)

I then send the band data via MQTT broker ?to all the other boards that need to know what TX band is seleced on the Flex Server.

Dave, what do you use to send Band info to your Band flow? That flow is interesting.

To finish the tour, here are photos of the radio hardware. ? The Flex and all its supporting hardware are located in a remote garage 300 feet from the “shack”. ?I use a fiber optic LAN connection between the house and the remote garage.

The Garage:

Top to Bottom (based on hot air rising to the top): ?Plaster LA1K, HF-Auto, Flex 6600, 1296 MHZ transporter, 2M Transverter, and 70CM Transverter. ?All enclosed in dust proof filtered air cabinet.

Support Hardware:

Elecraft W2 Wattmeter, SteppIR Controller, Cabinent Fan Control ,? DX Engineering Receive Antenna Controller, Green Heron Rotor Control, SMORF Antenna Analyzer, various serial to IP converters below.

The “Wall” behind the server cabinets. ?Power control on top, antenna control ?and ground bus on the bottom, UPS 12 battery on the floor:

Hi All

Just an FYI, we do have some storage space and there should be lots for flows.??

There is even GitHub integration that we should look?into.

Pictures are the ones that might take up a bunch of space, but we will keep an eye on it.

Dave wo2x and Andy va3cw are moderators as well and I know they will help.

I have tried several breakout boards and always had problems with the wires disconnecting.? They were very fragile and hard to make changes to (a "mess of "spaghetti")

I am currently using Electronics-Salon products, which have screw terminals.

This product has a built-in power supply and eight relays pre-configured to the Raspberry Pi GPIO pins.:

Along with the above board, with its pass-through GIPO header, and a ribbon cable, I added this board to give me access to all of the Raspberry Pi pins to screw terminals:

Lately, the shipping?from China has not been very timely, unless you pay extra for the DHL option. ? Amazon?has many of the Electronics-Salon products in stock and ship over-night.

Hi Kevin

?

Welcome aboard! I just built a Pi from scratch loading the software. Took just over an hour but I was taking notes along the way to make a how-to guide. I have very rough notes if you are interested. Has hyperlinks to the various software.
