Hi David,

I wish I had the ability to create code that would do this. Sadly I rely on others that can create the applications it to see some value. And yes I would pay for it.

For general portable use, there are a few applications that are on Android. DroidPSK, DroidRTTY, and Droid SSTV, are such applications. This makes portable convenient; for mobile (tracking) not so much. The author sells an interface for various radios which I have for my FT857D. I was trying to work mobile but had a couple of interesting issues which I believe can be tracked to RF getting into the phone via audio cable. I need to focus some effort on this. I'd like it to work for the next camping season.

I use APRSISMO on my smartphone. Recently the author, KJ4ERJ, added Bluetooth capability. He added it when Kenwood released the D74. Now I need to get my equipment back together in my vehicle and try it out. It should work with my BT dongle/OT3.

For me, this seems like an incredible time for amateur radio. What can be done with SDRs, and such, and at a price that is obtainable for many is astounding. The fact that a PC can be in a phone or small tablet form factor is amazing. I have a couple of the Winbook 7s. Maybe the correct path is to use one for APRSMessenger.

Best regards,
Fred N7FMH

Hi Fred

I'm sure you will have a very eager audience to turn old smartphones into smartradio. All power to your elbow. I look forward to seeing an article, I sure it will spawn a whole new generation of interest.

I had APRSMessenger on my phone for a long time. I was hoping that
eventually an soundcard interface might be added so I could plug directly
between my radio and my smartphone with a simple audio cable. It seemed to
me like an obvious path. At the time I had my FT857D in my vehicle and was
hoping to use 30M.

With the abundance of "outdated" smartphones it is an obvious choice rather
than building a custom controller with a four line LCD display. Those were
very cool at the time but the phones (even without cell access) have a lot
to offer. I have paid for less cool apps and I would have gladly paid for
this option. When I upgrade from my Galaxy S5, I will keep it for amateur
radio projects.

I attempted to use DroidPSK but I was not successful. I was hand forming
packets so I suspect I never quite got them right but it could have been

And, yes, I am an amateur radio operator.
