More field time with the new Icom IC-705 general coverage QRP transceiver

I’ve been using the Icom IC-705 pretty heavily since I took delivery of it a couple weeks ago.

The more time I spend with this radio, the more I like it.

Serious functionality and features

I originally stated that I’d probably sell the IC-705 after my review/evaluation period because it simply doesn’t have the design characteristics I like in a field QRP radio.

I tend to prefer simple field radios with a basic high-contrast LCD or analog display, and a protective cover over the display. I’m not personally the biggest fan of pressure sensitive touch screens in field applications.

Earlier this week, I stopped by Lake Norman State Park for a quick Parks On The Air (POTA) activation.

I wrote a field report on QRPer.com noting the fact that the IC-705 is a superb SSB transceiver. It truly is. I included a video showing the IC-705 as I worked a few stations on the 40 meter band, and another video demonstrating SSB memory keying (politely overlook the fact I had the rig set to LSB on 20 meters in that video–!).

Listening in

When I finish a park activation, I often spend a little time on the broadcast bands tuning around and enjoying the low-RFI setting.

At Lake Norman, I decided to make a short video highlighting the wide receiving range of the IC-705. The video only highlights a few bands–the IC-705 can actually receive from 0.030–199.999 MHz and 400.000–470.000 MHz.

The EFT-MTR end-fed antenna I had connected to the IC-705 that day was not ideal for reception above 15 MHz, but as you’ll see, it was adequate for a little radio fun. I was using the Emtech ZM-2 external antenna tuner that day because my mAT-705’s battery died.  I highly recommend the ZM-2 for shortwave listeners and QRPers alike because it makes it so easy to tweak wire antennas for optimal matching and reception. In the video, however, I left the tuner in the last matched configuration. This isn’t exactly a pro video, but I hope you’ll enjoy it anyway:

The Icom IC-705: A keeper

This transceiver is so versatile, I don’t think I can let go of it. I really appreciate the IC-705’s frequency versatility and excellent performance. With this compact rig, I can do some proper SWL DXing and possibly even FM and MW DXing.

As simple as it is, the built-in digital recorder clinches the deal.

The IC-705 is a pricey piece of kit at $1300 US, but I suspect Icom will lower the price or start offering rebates once the supply/demand curves normalize. At present, retailers are struggling to keep up with customer demand and most purchases are on back-order.

Blind Audio Test results

I’ve just closed the surveys for our IC-705 blind audio tests. The response was overwhelming and the results?  Well, you’ll soon find out. I hope to present all of the findings in a post within the next few days.

Radio Waves: Research on Gen Z Listenership, Early Women in Radio, Carlos Latuff Interview, and “Your Next Tech Purchase Should Be a Radio”

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Jeb, Dennis Dura, and Dan Van Hoy for the following tips:


Edison Research: 55% Of Gen Z Listen to AM/FM Radio Every Day But… (Radio Insight)

n their latest Share Of Ear study, Edison Research notes that over 55% of 13-24 year-olds listen to AM/FM radio daily.

However the study notes that these Gen Z listeners spend 50% less of their total share of time listening to AM/FM radio than the average 13+ population meaning they spend less time with radio than older generations. They also mostly listen to AM/FM in the car with 50% of their listening coming in vehicles. The study also notes that these 13-24 year-olds use a radio receiver 50% less than the average 13+ population, and they use their phones for listening 75% more than the average 13+ population with 58% more of their total share of time listening to streaming audio than the average 13+ population. Their share of YouTube listening, which is surveyed only for music and music videos, is 98% higher than the average 13+ population.

The study also notes that 89% of their listening to AM/FM is done through a traditional radio and only eleven percent coming from streaming of broadcast brands.[]

The Women Who Overcame Radio’s Earliest Glass Ceilings (Radio World)

Before the dawn of broadcasting, women were frequently hired as wireless operators, and so it was not a surprise that women’s voices were heard as announcers and program hosts in the early days of broadcast radio.

Sybil Herrold was perhaps the world’s first disc jockey; she played Victrola records on her husband Charles Herrold’s experimental station, which broadcast in San Jose from 1912 to 1917.

In Boston, Eunice Randall’s voice was heard on a variety of programs over AMRAD station 1XE (which became WGI in 1922). In New York City, WOR audiences regularly heard Jesse Koewing, who was identified on the air only as “J.E.K.” while Betty Lutz was the popular “hostess” heard on WEAF.

At WAHG (now WCBS), 16-year-old Nancy Clancy was billed as the country’s youngest announcer.[]

Coffee and Radio Listen – Episode 2 Carlos Latuff (Coffee and Listen)

Carlos Henrique Latuff de Sousa or simply “Carlos Latuff”, for friends, (born in Rio de Janeiro, November 30, 1968) is a famous Brazilian cartoonist and political activist. Latuff began his career as an illustrator in 1989 at a small advertising agency in downtown Rio de Janeiro. He became a cartoonist after publishing his first cartoon in a newsletter of the Stevadores Union in 1990 and continues to work for the trade union press to this day.

With the advent of the Internet, Latuff began his artistic activism, producing copyleft designs for the Zapatista movement. After a trip to the occupied territories of the West Bank in 1999, he became a sympathizer for the Palestinian cause in the context of the Israeli-Palestinian conflict and devoted much of his work to it. He became an anti-Zionist during this trip and today helps spread anti-Zionist ideals.

His page of Instagram (https://www.instagram.com/carloslatuff/) currently has more than 50 thousand followers, where of course, you can see his work as a cartoonist and also shows his passion on the radio.[]

Your Next Tech Purchase Should Be a Radio (PC Mag)

As the pandemic drags on, it’s time to return to a slower, older technology, one that frees you from the unending sameness served up by algorithms.

Quarantine has slowed everything down so much that it almost feels like we’re going back in time. The first few weeks were measured in sourdough starter, then in seeds sprouting from patches planted in backyards or squeezed into space on windowsills. Things are quieter now, but maybe too quiet.

Commutes used to be accompanied by music and podcasts piped in through earphones or car speakers. This casual sensory stimulation seems disposable, but it’s one of many small pleasures that have slipped away nearly—but not quite—unnoticed.

That’s why it’s time to return to a slower, older technology that can provide auditory companionship and match the new pace of your days: the radio.

Radios, more affordable and portable than TVs, used to be household staples and a more intimate part of people’s days—a companion in the bath or during a solitary drive or walk. Now they’re mostly found in go bags and as vehicle infotainment center afterthoughts.[]

Guest Post: What is FM Lightning Scatter DX?

What is Lightning Scatter DX?

by Bruce Atchison (VE6XTC)

Believe it or not, it’s possible to receive distant FM stations during a thunder storm. While lightning makes it difficult to hear AM and shortwave broadcasts, its crackles aren’t as evident on the 88 MHz to 108 MHz band.

When lightning strikes, it temporarily ionizes the air around it. Radio signals are reflected by the charged gasses and come back down to earth.

From my experience with this kind of DX, the signal became noticeably stronger during lightning strikes. This effect lasted for a second, then the signal level dropped to its former strength.

While a thunder storm raged overhead on July 7th, I used my CC Skywave SSB radio to check out the FM band. Instead of hearing E-skip as I had hoped, I found that tropo-like conditions reflected stations down to my home. I heard signals from a hundred miles away or further.

As just one example, I found a low-power station with the call letters CKSS on 88.1MHZ. They call themselves 88.1 The One. Find out more about this station at the http://www.881theone.ca/ link. It’s located in the town of Stony Plain, Alberta. This station plays country music and airs local news events.

At a guess, I’d say the transmitter is about 120 miles from my QTH in Radway. It normally doesn’t come in at all. The signal strength varied too, showing that it wasn’t a local.

In my instance of catching CKSS’s signal, a form of tropo ducting was also present. Rain can produce reflections of signals but it’s much more pronounced in the UHF and microwave bands.

When a thunder storm is ruining AM and shortwave reception, try DXing the FM band. You’ll be surprised at what occasionally comes in.

For further information on weather-related DX, check William R. Hepburn’s article.

To see a demonstration of lightning scatter on amateur TV, watch the
following video:

Thank you for sharing this guest post Bruce. I’ll be the first to admit that I’ve never tried to hear lightening scatter DX, but I will certainly give it a go.  This time of year, we’ve numerous thunderstorms in the afternoon and evening, so I’ll certainly have the opportunity!

External FM antenna for Android phones/tablets

Many thanks to SWLing Post contributor, Adid, who writes:

Check this little gadget for android phones or tablets

https://www.aliexpress.com/item/32976847250.html

If they have the FM app installed than this will come handy.

One needs to select speaker and not earphone as expected.

It works fine here. (I don’t know if Apple phones have an FM module)

Thank you, Adid! Very cool! This little antenna costs $0.90 USD–an insanely low price.

If you have an old set of earphones lying around the house (I probably have two dozen that ship with various radios) you could also snip off the earpieces and use the pigtail as a wire FM antenna.

Swiss Army Knife FM antenna

Many thanks to SWLing Post contributor, Balázs Kovács, who shares the following video of a Swiss Army knife and tweezers being used as FM antennas:

Click here to view on YouTube.

Thanks for sharing this, Balázs. The video actually makes a good point: it takes so little to make an effective FM antenna to receive local stations. I’ve been with repair technicians when working on radios They’ll often use their precision screwdriver as an antenna to test the receiver before reassembly.

I also carry a couple cheap instrumentation patch cord with alligator clips on both ends to act as a short antenna or antenna extension when needed. Honestly, It’s amazing how often I reach for them!

Guest Post: Roseanna snags some unexpected FM DX

Many thanks to SWLing Post contributor, Roseanna, who shares the following guest post originally published on her blog, The Girl with the Radio:


Unexpected FM madness!

I would like tho share with you a once in a lifetime Sporadic-E event that happened to me today along with videos of the catches I received during it.

It was about 12:00 UTC (1PM local time) and I was listening to NRJ on my personal FM transmitter (106.3MHz) when all of a sudden my pop music fuzzed and turned into classical music. It was then that I knew something was happening and I didn’t want to miss it!

I jumped up, got out my phone camera and started scanning around trying to find distant FM stations and my goodness did I get some amazing catches!

There was no tropo forecast for my area nor some of the places I heard and I wasn’t prepared in the slightest so I ask for your forgiveness on the shaky unprofessional footage and I hope you enjoy watching the following catches that I received!

For those interested my setup is a Sony ST-SE570 with a “bunny ear” telescopic aerial with the ground positioned vertically and the feed positioned horizontally. I put the feed to be facing at 90 degrees East to West.

Disclaimer: the order in which these stations were received has been altered to make this blog post more fun, the times in UTC are in the video titles for those of you interested in the chronological order in which I received these stations!

First stop: Czechia!

Click here to listen via YouTube.

This is an amazing catch to start us off; 10kW at 1300km with RDS!

Click here to listen via YouTube.

This one is even more impressive that the last one at 5.5kW with RDS, I still am surprised at these catches watching them back!!

Next stop: Romania!

Click here to listen via YouTube.

This catch is just insane. I have BBC Radio 2 on 88.1MHz and you can hear RRA and BBC R2 fighting to be heard!

Click here to listen via YouTube.

And this catch …. I have no words to describe my sheer amazement, surprise, shock and excitement hearing a station from Romania (Over 1800km / 1100 miles away) that is broadcasting at only 2kW. It is on the same frequency as France Musique broadcasting at 160kW which is much much closer; I still can’t believe I heard this at all!

After all that excitement we now stop over in Slovakia!

Click here to listen via YouTube.

This is a much less insane catch compared to the last few but it is still awesome! Disclaimer: I skipped a load of fading in the recording where it fades.

Click here to listen via YouTube.

And here is SRo 1 again, however this time a much lower powered transmitter compared to the last one and yet the signal is still really good and most of the RDS data was decode-able!

Click here to listen via YouTube.

Here is SRo 4, 20kW and some of the RDS decoded. an UnID was on 94.6MHz which made this quite awesome to get the RDS PI!

Click here to listen via YouTube.

And for our last stop in Slovakia we meet Fun Rádio, an 18kW station with RDS received!

Our last stop on our FM journey; Hungary!

Click here to listen via YouTube.

This is Retro Rádió a 50kW station in Hungary. It was broadcasting over BBC Radio Wiltshire and I even got RDS!

I hope you all enjoyed going on this radio tour of Romania, Hungary, Slovakia and Czechia with me, I certainly did!

Thank you ever so much for reading and watching and I hope to see you around for my next adventure!


And thank you, Roseanna, for taking us on your FM travels! Isn’t RDS an amazing tool for grabbing station IDs during these FM DX openings–? Well played! Again, many thanks as I enjoyed your FM tour of eastern Europe.
