An iPhone app and Paul’s secret for successful reception reports

VoiceRecorderIconMany thanks to SWLing Post contributor, Paul Walker, who writes:

Wether you do AM, shortwave, longwave, FM or something else, I think this will prove useful.

I have a pretty high return rate when submitting reception reports and asking for QSL cards/letters. I’d say my return rate is probably better than 60 percent, sometimes even 70 or 80 percent. It just depends.

But what helps me so much? EVERY reception report I email or snail mail includes an audio recording. Sometimes it’s only 30 seconds if the signal is really rough, weak or hard to pick out anything useable. Sometimes I include anywhere between 5 minutes and 30 minutes with a detailed report.

Well, how do I record? I use my smartphone! I have an iPhone 6 Plus with 128 GB of storage. iPhones record some of the best audio I’ve ever heard from a smartphone. Androids do a pretty decent job–not as good, but not bad.

The best app I’ve found for this is Voice Recorder Pro 7.

You can select the recording format (mp4, mp3 or wav), you can select the sample rate, bit rate (32kbps all the way up to 320kbps), you can select mono or stereo as well.

But where this really comes in handy? You can email the audio file to yourself or someone with the click of a button, you can upload it to a google drive, dropbox, one drive or a box cloud account. You can even have it upload to an FTP server or to your Facebook page if you want!!

The one feature I like is being able to turn audio into a YouTube video and uploading it directly! I was recording videos by holding it up to the radio’s display and while the audio was good, it wasn’t great because it was a bit further away from the speaker so I could show the S meter and frequency on the display.

So what I ended up doing is to put the phone right near the radio’s speaker and start recording… this produces better audio then a straight up video. Then you click a button after the recording is over and it generates the video frames for you, putting a picture there; you fill in the particulars of your video and it uploads it to your YouTube account.

See what I’m talking about here, by viewing my YouTube account:

You can easily tell which videos were made by me holding up the phone to the radio’s display and which are audio only with the video generated by Voice Recorder Pro 7.

Here’s an audio only track I recorded to give you an idea how it sounds.

I don’t recall if they have this app for Android phones, but if they don’t, there’s something similar. It’s worth investigating.

A detailed written report is one thing when requesting a QSL, but audio is indisputable and absolute confirmation of what was heard.

Many thanks for the recommendation, Paul. I use an Android phone (the Moto X 2nd generation). I’m hoping a Post reader can suggest a recording app that is equally robust.

Like you, I typically send an audio recording when submitting a reception report. It’s certainly a valuable piece of information for broadcast engineers. Thanks again!

Shortwave Radio Recording: “The Buzzer” on 6,998 kHz

UVB-76-Buzzer

Screen capture of the Web SDR waterfall tuned to 6,998 kHz.

On Friday, Andrea Borgnino, tweeted that he could once again hear “The Buzzer” on 6,998 kHz. Of course, during the day, I couldn’t hear  the signal from my home in North America.

I could, however, easily hear the signal via the University Twente Web SDR in the Netherlands.

Here’s my recording:

As I’ve mentioned before, I’m pretty sure this is simply a pirate having a little fun relaying UVB-76 audio on 6,998 kHz.

Hearing Ghadir: Iran’s Sepehr Phased Radar System

Mehdi-Waterfall

In response to Andrea’s UVB-76 recording, SWLing Post contributor, Mehdi, comments:

Thomas, another signal which may sound mysterious:

Iran’s OTH Radar, named “Ghadir”; part of Iran’s Sepehr Phased Radar System.

They’d polluted the 10-meter band [in the past]; now they transmit on 26MHZ. (See spectrum in screen capture above.)

By the way, here’s my recording of UVB-76:

Many thanks for sharing those audio clips, Mehdi! Now I’ll know what Ghadir sounds like, should I hear it on the bands.

Tom Laskowski, has been generously contributing a number of off-air shortwave radio recordings to the Shortwave Radio Audio Archive (SRAA).

Recently, he shared a series I’m sure many of you remember. Tom writes:

My first contribution of many recordings I have of Radio Canada International’s Shortwave Listener’s Digest hosted by Ian McFarland.”

“The first 12 1/2 minutes is Bonsoir Africa. The recording was made using a cheap GE portable. The audio quality isn’t great but it’s still very nostalgic listening to a program I recorded 34 years ago.”

This brings back many memories of one of my favorite shortwave programs–thank you, Tom!

The audio quality actually reminds me of one of my first analog portables, Tom! Nostalgia at its best.

Shortwave Radio Recordings: RCI, BBC, VOA circa 1979 & 1981

HalliDial

Many thanks to SRAA contributor, Tom Laskowski, who shares the following recording and notes:

A few snippets from my old shortwave tapes that were too short to upload individually. These were made using a GE portable multi band that had poor selectivity, hence the annoying ute during the BBC clip.

Times of individual clips are:

  • 00:00 – 01:59: 1979, July 19 – RCI, frequency announcements in English and french.
  • 01:59 – 09:51: 1979, July 20 – BBC, newscast, bothered by an annoying utility station.
  • 09:51 – 11:38: 1981, August 28 – VOA, science news item about Voyager 2
  • 11:38 – 14:52: 1981, August 29 – VOA, science news item about Voyager 2

Shortwave Radio Recordings: Radio Spaceshuttle International

Space_Shuttle_Atlantis-NASA

SWLing Post and SRAA contributor, Jim Clary (ND9M/VQ9JC), recorded the following final broadcast of Radio Spaceshuttle International while on board a US Navy ship off the coast of Rota, Spain. Jim notes:

I was packing up to leave my ship and return to the USA this week when the latest SWLing Post e-mail showed up with info about SSR’s final broadcast literally seven minutes before he was to come on the air. I’d already broken down the receiving gear, but it came back together in record time, and I was able to get the recorder going with a minute before the transmission started.

Jim, thanks so much for putting all of your receiver and recording kit back together to make this recording!

Many thanks to SWLing Post and SRAA contributor, Tom Laskowski, who shares this recording of the Voice of America; recorded on July 20, 1979 at 0500 UTC on the 31 meter band. Tom notes:

“The first 4:30 is from a VOA newscast that aired before the main part of the program. The main recording was presented on the 10th anniversary of the Apollo 11 moon landing. I enjoy listening to this every year on the landing anniversary.”
