Besides being a bit of a radio geek, I also love aviation and am working on my PPL (private pilot license). I recently discovered this image [above] of the Boeing 787 antenna compliment. It’s amazing to see how many antennas they fit on this heavy bird!
Thank you for sharing, Sally! I can assure you, you’re not the only aviation nut here on the SWLing Post. I’m guilty as well!
It is amazing to see just how many various antennas are install on modern commercial aircraft. Looking at this image, you would think it’s a flying antenna farm!

Last week I took an Eton Satellit with me on a flight from Tampa, Florida to Washington DC. The radio is very light, portable and packed with features. I have used an SDR radio before for inlight FM reception where I recorded audio, but this time I decided to only count stations with an RDS lock. With so many signals battling RDS is tricky to catch as every 10 seconds or so one station comes on top of another. The flight was just short of 2 hours and I divided my logs into three 30 minute segments. Not suprisingly looking into the technicalities I noticed RDS is commonly received from stations 50 -100 kW of power and tall towers.
Interestingly signals seem to be stronger a lower altitudes. My theory is that FM broadcast antennas heavily favor gain on the horizontal plane parallel to the terrain and send as little signal as possible out into space. I overlaid my logs onto three maps and also a video:
Impressive Ivan! I’m taking a flight later this month and might even try this with the FM radio built into my Moto G6 smart phone which also includes RDS (although I doubt reception can match that of the Satellit.
Parents of children in South Australia’s outback are calling for the state’s School of the Air to become independent so it has more control over how students learn.
The school at Port Augusta in the state’s north has marked its 60th anniversary of delivering lessons to students in remote areas.
When the school began in 1958, lessons were given via high frequency (HF) radio, but are now done over the internet.
In 1991, the School of the Air amalgamated with the SA Correspondence School to become Open Access College, which is based in Adelaide.
At a recent meeting in Port Augusta, the Isolated Children’s Parents’ Association called for the School of the Air to become an autonomous education provider.
The association’s north-west branch president Lynly Kerin said it was “no longer beneficial or manageable” for the school to be part of the college, and that its 49 students were being overlooked in the college’s cohort of 5,600 students.
Ms Kerin said the School of the Air community felt “overshadowed by decisions being made by people who may not understand the needs of our kids out here in remote areas”.
“At the very least, we request that the Minister look at an investigation into the change that we’re proposing,” she said.[…]

HI Thomas, I thought I would put this idea out to your site – in case it isn’t already there. It’s a brilliant solution to the apparent lack of a working Air Band scan function on the Tecsun PL-660. Note – I did not come up with this idea, but came across it in a Yahoo group.
It IS possible to scan the Air Band on the PL660, as long as you have picked out WHICH Air Band frequencies are in use in your area. There are websites which list these frequencies for each airport:
Put in a shortwave frequency in the first empty space; the “00” slot.
Then fill in the succeeding spaces on that page with the Air Band frequencies you’ve chosen.
Now go back to the “00” slot and hold down the scan button.
Works on my set!
What a cool trick! I’ve lent my PL-660 to a friend, but as soon as I get it back, I’ll also try this trick by setting up a page dedicated to my local aviation frequencies!
