Working towards setting up my FT-480HX for digital modes....

(Hang tight, later on I will be setting up my Ten-Tec Paragon for digital as well )

SO - None of the computers at my disposal have a DB9 port - - There are lots of cables available to go from DB9 to USB out there -
Which would I use?  Or would the cable I ordered from RT systems for programming my FT-480HX do the job?

Do you have a schematic for that cable?

I use one with a prolific chip but one with FTDY should work equally well.  Source--Best Buy, Office Depot, Staples, etc.  $15-25 at the store.

USB all the way! For me, using HRD / DM780 /  and WJST-X (Which works with HRD Automatically)...(Transceiver Kenwood 590S)

But us of USB, controls not only the radio but the signalling...

One Cable no mess...

The USB / DB9 cable should be here today - And I no very little about digital modes - I will have lots of questions.
I have FLDIGI and WSJT-X downloaded, looking forward to getting the cable and playing!

If it is a desktop computer and you have a open slot, put a serial card in it. They are not expensive and are trouble free.

I bought a $3 USB->serial dongle on eBay when I built my digital interface. It's based on the CH340/CH341 chip.

I had to replace the USB cable because the one attached to it had no working shield and it caused a lot of QRM. This lead me to replace the non-can 12mhz crystal with a canned one after breaking it while getting in to the thing. Those are "minor" hassles for me as I had all the stuff I needed in the "junk bin" and a few seconds with a soldering iron.

The only issue I had with it was it didn't like the USB controller on my motherboard, it would occasionally drop the RTS signal for a fraction of a second. I plugged it up to my USB3 card and it worked just fine. Threw Windows 10 on this machine about two weeks ago and it even installed the driver without me having to do anything.
