Wanted to share some correspondence that I had via email with a ham on a science project. Neat stuff!
Thanks a lot Jeff - it's working better than I thought it could.
We're sending large images with ease via simplex across the county.
It's just great.
We'll make some vids at some point.

Tom,
BPSK250 or BPSK1000 usually work well on FM repeaters.

No problem with taking time to get back to me Jeff.
Being busy at work sure beats the alternative, huh?
We'll get the girls working on AndFLMSG with their Android phones and tables for now. That'll give them plenty to do.
What digital mode do you recommend use for FM repeater work?

Tom,
There is an Android version of FLDIGI that would work for going cell phone to cell phone via audio. It is called AndFLMSG.
If you are willing to go up to the $80 tablets that are available (Winbook 700s and HP Stream 7s), you can run FLDIGI on a windows environment. Or you can go with the UZ7HO soundmodem, which allows multiple modes in both FSK and PSK.
If you stick with Linux, there is a version of Dire Wolf (packet and APRS soundmodem) that will run on the Raspberry Pi (version 2 or 3). You can also run FLDIGI on the Raspberry Pi. I personally prefer to attach the Pi to the 7" touchscreen that is currently sold for $65, as it makes it very tablet-like.
Hope that helps you out. Sorry it has taken this long to get back to you!

Subject: Digital modes on HT's
Hello Jeff,
I've operated FLDIGI from a laptop hardwired to radios in years past.
I recall being able to Tx and Rx from the speaker/mic of the laptop to the speaker/mic of the HT.
But I can't recall the digital mode, or the software used.
Nowadays, I would hope that we can do that same thing with smartphones running FLDIGI (or some other the text-to-tone software) audibly coupled to an HT.
I have two new hams KM4BUN and KM4PQG anxious to demonstrate "text messaging isn't just for cell phones" as a science project.
Of course, hardwired audio improves S/N, but for demonstrations, it's good to let the audience hear the process as well as watch the text appear.
Any suggestions you can send this way are appreciated.
