Working WSPR With a Phone APP

 UPDATE:
Added, additional details.

Today for fun, I wanted to try working with WSPR again, I have not done that for a long time.

I found a Android Phone WSPR Beacon APP, that generates the WSPR tones, which when acoustically coupled to a Radio with VOX, transmits as necessary.

The Acoustic WSPR Interface
(Note: Unlike what the photo shows,
the Power was actually set to 5 Watts)

The Radio was Set Up for VOX on 20M

The WSPR Beacon App runs on both my Cell Phone and my Samsung Android Tablet. As with all WSPR programs, the system clock must be set within a second (or two) of the real time.

The Cell Phone network maintains my phone with an accurate system clock.

But my Tablet does NOT allow itself or "third party" Apps to "Automatically" change the clock from an Internet or GPS time standard. And therefore, an Interactive Clock Set is necessary. I use the ClockSync App for this. It is reasonably simple - just set the Time to the next whole minute, and then press an on-screen button at the beep (after a count down, it tell you when).

Using my Cell Phone to Generate WSPR Tones, here are the results on the WSPR Map:

16 Stations, 89 Spots

From My Location

After 2.5 hours of working 40m and 20m, my WSPR Beacon was received by 16 stations for a total of 89 Spots, some spots were obviously repeats. The furtherest station was 3894km.

Note: The WSPR Phone APP is "Beacon-ONLY", that is, it does NOT receive, decode, or report on signals.


It was fun and simple !
