WSPR Beacon MATLAB GUI App Improved functionality.

As proof of concept, here is a simple Matlab GUI app demonstration. Using earlier released code Matlab App designer was used to create a gui panel to enter callsigns and grid square locators and then transmit a WSPR call for up to 6character standard HAM callsigns using these. A flowgraph in GNU Radio Companion is used to take audio produced in Matlab and modulate an RF carrier producing an USB signal that is sent to the HackRF One. New code and an extra button have been addede giving the ability for the app to start Tx automatically on the next even minute and to make it possible to set the number of two minute cycles to transmit. Transmissions at low power and with a short wire antenna are monitored using an rtl-sdr dongle via SDRSharp, VB Audiocable and WSJTX. The App functions well for most callsigns but fails for those beginning with 'EA' or 'HA' and others for some reason. It uses the well known chr_normf() subroutine to encode the callsigns so not sure why this is.Code available upon request. Please support this channel. Thank you!
