Skywave Radio Schedules now on the Google Play store

Skywave Schedules App will allow you to search a comprehensive, regularly updated, database of shortwave radio broadcasts.

Many thanks to SWLing Post contributor, Cap, who has just notified me that his shortwave radio schedules app for Android–Skywave Radio Schedules–is now available via the Google Play store.

You might recall that Cap first shared this app in Beta form and invited us to share feedback and comments. Cap has spent weeks incorporating our suggestions and making changes in the background–Skywave Radio Schedules feels refined and responsive. Best yet?  It’s free and has no ads. Amazing.

Cap does note that you should uninstall any previous versions of this app before installing it from the Google Play store.

Thank you, Cap! Great job making this app a reality.

Zello transformed Holly from onlooker into dispatcher

As a follow up to our previous post about the PTT “radio” app Zello, SWLing Post contributor, Aaron Kuhn shares this story from The Houston Chronicle:

I downloaded an app. And suddenly, was part of the Cajun Navy.

After watching nonstop coverage of the hurricane and the incredible rescues that were taking place, I got in bed at 10:30 on Tuesday night. I had been glued to the TV for days. Every time I would change the channel in an attempt to get my mind on something else for a few minutes, I was drawn right back in.

I finally turned off the TV and picked up my phone to do a quick check of email and Facebook. I read an article about the Cajun Navy and the thousands of selfless volunteers who have shown up to this city en masse. The article explained they were using a walkie-talkie-type app called Zello to communicate with each other, locate victims, get directions, etc. I downloaded the app, found the Cajun Navy channel and started listening.

[…]As I was listening, I quickly figured out that there were a few moderators on the app that were in charge and very experienced in using this method of communication during emergencies. One in particular, Brittney, was giving directions, taking rescue requests, and prioritizing calls and rescues. At one point, she said something that made me realize she’s a nurse, so I immediately understood why she was so effective in this situation.

A couple of other women (who were working from other parts of the country, not Houston) who had been taking calls from victims and logging in the information came on the line around 12:30 and said they had to sign off so they could get to bed. They asked if there was anyone who could work through the night to keep taking rescue requests and log them.

I sat up and turned on my light. I timidly pushed the “talk” button and said, “I can.”[…]

Zello: A PTT (push to talk) app surges in popularity with Hurricane Irma

(Source: The Washington Post via David Korchin)

As Hurricane Harvey dropped anchor over Southeast Texas last week, Zello became the go-to app for rescuers working to save thousands of people trapped by floodwaters.

Within days of Harvey’s arrival, the app saw a 20-fold increase in usage in Houston, according to Bill Moore, the Austin based startup’s the chief executive.

As Hurricane Irma hurtles across the Caribbean toward the coast of Florida, Zello continues to boom in popularity. The free Internet “walkie-talkie” app — which relies on cellphone data plans or WiFi and is designed to operate in places where signals are weak — became the top app on iTunes and Google Play Wednesday.

The latest influx began Tuesday and, at one point, Moore said, 120 people were registering for the app every second. In recent days, the app has also trended on Facebook and Twitter, offering another example of the pivotal role social media is playing in natural disasters.

“The heat map of where the registrations are occurring looks like the hurricane’s forecast path,” he added. “It’s very dense at the tip among the Caribbean islands and then fans out across Florida.”[…]

I find Zello quite interesting. If you think about it, this app mimics the concept of traditional PTT/two-way radio which certainly has traffic management advantages during times of emergencies. Of course, Zello has many features traditional two-way radio does not (voice history, the ability to leave messages, native GPS and mapping functionality, etc.).

Zello does rely on some sort of Internet connectivity via 4G, 3G, WiFi, GPRS and/or EDGE. During disasters, these services may not always be accessible. Of course, amateur radio, CB and other traditional radio services do not require Internet connectivity.

Zello requires no license, no radio, nor any other accessories–just a smart phone–and is free. That’s a powerful combination and, as The Washington Post reports, Zello is obviously helping with Irma relief efforts. Thanks for the tip, David!

Shortwave Radio Schedules adds Premium upgrade

Many thanks to SWLing Post contributor and app developer, Stephen Cooper, who shares this press release:

7th August 2017 – Shortwave Radio Schedules adds Premium upgrade

Popular Android app Shortwave Radio Schedules has this week been updated to add two of
the most requested features as a premium upgrade to the app.

“Now” and “Favourites” options have been added to the app which currently is free in the
Android Play Store.

Current free features which will always remain free include the ability to search EiBi and
AOKI shortwave schedules by station, time or frequency. Search results are shown in a list
and can then be displayed on a map showing beam directions and broadcast power. The log
feature also allows a log to be kept of stations heard including SINPO rating with the ability
to export logs or share individual loggings via social media.

The new Now tab shows what stations are currently broadcasting using an innovative “radio
dial” style interface to browse through each shortwave band in the same way as a radio
would be used to tune up and down the bands.

The Favourites option allows stations to be “starred” and added to a favourites list making it
easy to quickly lookup the frequencies of stations regularly listened to. These favourite
stations can also be shown on a map.

All options including maps and logs are available offline (once the initial schedule download has taken place) making the app perfect for taking on DXpeditions where internet connectivity is not available.

The App is free in the Google Play Store with the Premium upgrade (adding Now / Favourites tab) available for GBP£1.49 / USD$1.49 / EUR€1.69.

Shortwave List: Cap’s shortwave schedule Android app now open to Beta testing

A few months ago, long-time SWLing Post contributor, Cap Tux, designed a simple shortwave schedule application for his Android phone. Though he never intended to make the app public, he shared it with me to test on my Moto G5 Plus.

Cap has recently decided that if others in the SWLing Post community would like to Beta test his app, they’re welcome to do so. He notes:

The app was created initially to meet my own requirements as at the time I was travelling a lot for my job and other apps I tried didn’t meet the requirements e.g. Broadcast stations only, filter by Station, Freq, Time, Language and more recently ‘Target Area’ which was added to the app very recently as I was initially using the AOKI list but found that EIBI was updated more frequently and tended to be more accurate.

I do miss some of the features and simplicity of the AOKI list as programming some of the code to respond to the amount of info in the EIBI list was challenging and there is still more that can be done. There is a bug on Android v4.4 (not my bug but the frameworks bug) which I have fixed in v1.1.10 which I can send through later.

I wrote this app as I needed a phone app for my portable radios (PL-660/PL-365) so I could search for shortwave stations using any combination of Station, Frequency, Language, Time (Specific, Real-time incl. day or Any!) or Target Area. The search can even take account of the day of broadcast so if it’s a Friday and the broadcast is only a Saturday, then it won’t show it.

Shortwave List Features:

  • Search the list using any combination of Station, Frequency, Time, Language, Time or Target Area
  • Only broadcast stations are included in the list
  • Scrollable list of stations based on search criteria
  • Get Station, Frequency, Times, Language, Target, Days on-air, Transmitter location and the Broadcasters country of origin of the selected broadcast by a tap on a station
  • Powerful search features with a simple interface
  • Search for specific broadcast times with any combination of Station, Frequency or Language, Target area with future or past times being searchable, although this lists all stations irrespective of the day (as you may want to know a time for a broadcast tomorrow, or yesterday)
  • Search for stations in real-time with any combination of Station, Frequency, Language or Target Area, so the app only lists broadcast stations on-air now (also takes the day into account, so, for example, a station listed as only on-air on a Friday will not show if today is a Saturday)
  • Search for stations transmitting at any time with any combination of Station, Frequency Language or Target Area

Future features in active development:

  • Update shortwave list from the internet

A few examples of use:

  • You hear a station in an unknown language, Select ‘ON AIR’ and enter the ‘Freq’, ‘SEARCH’ and the app will list the possible stations
  • You hear a station in English, select ‘ON AIR’ the ‘Language ‘ set to ‘English’ and enter the ‘Freq’, ‘SEARCH’ and the app will list the possible stations on that frequency right now
  • Want to know when a station is transmitting at a specific time? select the specific time by selecting the UTC time, set the Hour/Minute and enter the station name in the ‘Station’ box and ‘SEARCH’
  • You are listening to a SDR recording from last week and trying to identify a station, enter the ‘Freq’ and the specific UTC time (or ‘Language’ if known), ‘SEARCH’ and the app will list the possible stations
  • Want to tune into broadcasts right now in your language? no problem, just select ‘ON-AIR’ and select your ‘Language’ and ‘SEARCH’
  • List all broadcasts from a specific station, just enter the ‘Station’ name and click ‘SEARCH’
  • List all broadcasts on right now by selecting ‘ON-AIR’ and ‘SEARCH’

Phones that have been tested and will work (You will need Android v5.0.1 or above):

  • Samsung Galaxy S4/S7 (I think all the S series from S4 above should be fine as all have a good screen resolution)
  • Samsung Galaxy J3
  • Google Nexus 4
  • Moto G5 Plus

It should be noted that due to the number of low resolution display phones out there some will not be able to operate the app correctly at present due to the current layout of the components and recommend you use a phone with a decent screen resolution around 1080×1920. I plan to address the screen res issue soon.

What I need from Beta-testers who want to file bug reports:
Phone Make/Model:
Android version:
Shortwave List version in use:
Ease of use:

Thank you, Cap!

Readers, please keep in mind that this application is not in the Google Play store because it’s in Beta. You’ll need to download the application to your phone, temporarily allow “Unknown Sources” (here’s a short tutorial), then install the app. It’s very important to only temporarily allow “Unknown Sources”–once this app is installed, please reinstate this security measure.

Please note: If you’re not comfortable downloading and installing an app that is not in the Google Play store, please simply wait for this app to hit the Google Play market possibly at some point in the future.

Click the following link to download the application file to install:

http://www.filedropper.com/shortwavelist-v119-no-permissions

This app requires no permissions. The trade-off is that updates to the schedules cannot be initiated without re-installing an updated app with new schedules embedded.

For what it’s worth, I really like this app! Very simple, effective and works offline.

Here are a few screenshots–I love how he’s kept the interface clean and simple:

Thanks again, Cap, for opening Beta testing to our community.
