1. The radar timestamp is old and/or the program is telling me check the timestamp.

While the National Weather Service, FAA, and Department of Defense work dilligently to maintain a high uptime on every radar site, sometimes things happen. Routine maintenance is typically handled on "good weather days" but unexpected issues do occur. The WSR-88D is a very complex piece of hardware and software. The national radar network is US Government owned and maintained.

Be certain that you have the latest version of the program

In PYKL3Radar, you can:
Long press over a radar site and select "Radar Status" to view the latest site-entered information--also known as a Free Text Message.
Navigate to Menu:>Settings>Info and Support>Web resources>NWS Feed radar network status

Alternatively, CaprockWeather has put together this Radar Status Page where both the status and Free Text Message may be viewed.

On rare occasion, the National Weather Service has been known to have outages. If you visit the suggestions above and all or many radar sites are down, there is a widespread outage in progress. Check both the NWS Page and our Third party data providers AllisonHouse and CaprockWeather for their radar data status.

  • If all three show many sites down, a Nationwide Outage is in progress (rare)
  • If the NWS Page shows many sites down, but AllisonHouse and CaprockWeather do not, then there is a NWS web server outage (historically this is more common). These data providers exist as they have alternative means of receiving the data and offering that increased up-time (and other features) as a value added service.

Finally, if the above does not address what seems to be going on, then it is possible that the Cache on PYKL3Radar may need to be cleared. Mobile environments are harsh and lost data connections, ungraceful shutdowns, battery running out, etc can have detrimental effects on your device. PYKL3Radar is designed to handle as many of these situations as possible, but sometimes, it is beyond the control of a software developer.

To clear the cache, select Menu>Settings>Info and Support>Reset Options>Clear Cache. Exit out of the program entirely by pressing the back key and restart.

Note: Uninstalling and re-installing the program typically is not a solution to most issues that are encountered.

If you're still having issues, contact and we'll help you.

2. I upgraded my phone or Google Play is asking me to purchase again. Can I install PYKL3Radar on the new device?

All purchases are tied to your gmail account which MUST be active on the device you are trying to use. Treat the account like gold. If you delete your gmail, you will forfeit any Google Play purchase. Please see Google's policy. We are sorry, but Google does not permit the transfer of product licenses from one account to another. Please see this section of our user's manual for more information on related issues.

3. I'm having some other issue with the product. How can I get help?

Just write us and we'll help you out. As an aside, we do not provide product support via social media or via product reviews. We handle support on an individual by individual basis to ensure the most timely resolution.

4. Where can I get the latest version?

Visit Android Market or Amazon's app store on your device

5. What are the ticks on the bottom of the color bar?

These ticks represents increments of 10. Thus, on a reflectivity product, every 10dBz (-33dBz is the minimum value normally encountered). In velocity and spectrum width, data, the ticks represent 10 knots. On velocity products, 0 KTS is in the center of the screen. To get a more detailed description, simply tap on the color bar.

6. Is it possible to change the color palette for the various products?

Yes, in fact, this is possible. If interested in more information, see our user's manual.

7. What is the large file that downloads when running the program for the first time.

GIS data--mainly for cities, extracted from public domain data..

7.1 These files download every few days and thus the startup time of PYKL3Radar is quite slow

This issue is caused by a "File Cleaner" type of app that you have installed.  What is happening is that the file cleaner is removing files that it shouldn't be touching.   That is, those used by PYKL3Radar.  Most file cleaners have a mechanism whereby the user can have the program omit certain directories.  In this case, it's /sdcard/PYKL3Radar.  /sdcard doesn't necessarily mean that it is an external sdcard and another name is possible.  The bottom line is that the file cleaner should be instructed to not touch files in any directory containing PYKL3 (case sensitive.) In general, file cleaners can be quite dangerous as they may inadvertantly delete valuable data that might be on your device. It's far better to perform any file paring yourself than to use these applications.

8. What is this frequency swept audio sound that occurs every 5 to 10 minutes?

This sound indicates that a new base reflectivity radar image has just completed rendering. E.g. have a look at the radar again! It may be disabled via Menu>Settings>General Preferences>Enable Sounds

9. Can you perform image smoothing on the radar to make it look better?

The EVAPS feature (In-app purchase) provides intelligent image processing which maintains data integrity unlike many smoothing options you may have seen.

10. Why does GPS not appear to work?

This program respects your global phone privleges. You may need to globally enable GPS on your phone by finding Settings/Location/Use GPS Satellites.

11. Is the program available for iOS or Windows?

PYKL3Radar is exclusive to the Android platform. There are no plans to bring the product to iOS/Windows
