    Most folks on QRZ know about this app, but I thought I'd post this for those that take news feeds off of QRZ.COM. You can access it from any smart phone browser at . The text below describes the functionality of the programs associated with the app.


    KY5U Mobile Assets (KMA) is a collection of HTML/HTML5/Javascript Apps designed to be used by Amateur Radio operators on smart phones. It consists of a home page/desktop of icons that may be clicked or touched (on smartphones) to initiate the individual apps. KMA is brand independent for phones/tablets so it may be used regardless of what kind of device you use.

    KY5U Mobile Assets Desktop


    Access KMA via the World Wide Web at on your device. The main screen and sub-screens are small HTML files residing on a server. These HTML files run local applications or link to applications on the WWW that radio amateurs may find useful.


    The following is a brief description of ther use and functionality of the included applications. Please refer figure 1 above for the type and labeling of icons used. Feel free to email your suggestions for additional applications to the address at the end of this document.

The timer continues to run whether you acknowledge the alert box or not, thereby keeping the 10 minute interval. To stop the timer, exit the application. Powered by KY5U.

    CLUSTER- Powered by K5DX, this application parses the K5DX telnet cluster data and builds an HTML file every 30 seconds. The application refreshes every 30 seconds to display the updated list formatted for the smartphone screen.

    This appears to be a really great resource. Thanks for the hard work. I think I will get a lot of use out of this.

    Check out the two tone generator. Put your phone near your mike and use the audio to tune up on SSB. You'll see an improvement in power when you're on the air over tuning in AM or with a pecker tune feature on an amp. Thanks for your comment!

    Great Job...

    Adding the Google Mobile Bar Code to this article just seems like a natural step...
    ... then those reading on PC could just hold their phone up and scan to correct URL...

    ... just a thought

    I'm glad you did post a link here as this is a new information to me. When I get home this evening I'm going to try tuning the rig with the two tone generator just to see what happens. Ok, I'm weird like that! Thanks again,

    Here you go. The QR code for the KY5U App. Great Suggestion.


    Also remember in iOS to click the "page" ICON and "save to home screen" to make the Web App appear as an app on your iPhone/iPad. Android has the same thing although I don't remember offhand how to do it.

    This guy seems quite clever... It's a shame he felt that he had to steal his icons from other programs without even so much as a nod to their respective creators.

    The ICONS used were from a free group available on the web by deviantArt. The artist was "Adrenn". I appreciate your concern, but your point is erronious. Thanks!

    I've tried this on my iPhone 4. There's obviously a lot of good stuff in here, but the mysterious, animated, rotating and unlabeled icons on the home page are way too clever for me.

    When I want to use a function, I want to use it right then and not have to try to remember what symbol represents what app, nor wait for it to come around on the page.

    A static home page with icon labels would do a lot to improve this app's UI.

    I made this observation in another thread. I did a quick search on the deviantArt website and typed quicktime and poped up a bunch of quick time logos.

    Just because they are on a website freely available doesn't make them free to use. If SOPA had passed you would have had to take the icons down.

    Divix, Steam, VLC, QuickTime, Sonic Media, Open Office, uTorrent. Thats just taking a quick look. The uTorrent is quite obvious.
