Digitech AR-1780: unboxing, photos and initial impressions

[UPDATE: Click here to read our full review of the Digitech AR-1780.]

Yesterday, prior to heading out the door for two days of travel, I received the Digitech AR-1780 I ordered ten days ago from an Australian eBay vendor. I’m very pleased with how quickly the order was processed and delivered via the post. The radio arrived in a rugged mail pouch and was double boxed inside.
I’ve had no time to evaluate the radio’s performance yet, but I thought I’d post a few photos I took while unboxing the AR-1780.

There’s not much in the box: just the radio and an owner’s manual. There are no batteries, no charger, and no case or carry bag. That’s okay though as the AR-1780 takes standard AA cells and I have an assortment of bags that can protect it in my suitcase.

The buttons all have a responsive, tactile feel. The hard plastic chassis feels durable.

I really like the dedicated fine tune control on the right side of the radio. Nice touch! But 7 VDC in? That’s an odd voltage for a power supply. That’s okay by me as I never use wall wart type power supplies due to inherent noise–rechargeable Enloop AA batteries are how I power all of my portables. Bonus! There’s also a dedicated external antenna jack! One odd thing, though, is the AR-1780 breaks the convention of having the volume control on the right side of the radio–it’s on the left instead. Last night, I tuned around the 31 meter band and the AM broadcast band. I listened to the French language service of Radio Romania International from inside a noisy house–armchair copy.

The AR-1780 has an impressive 7 AM bandwidth settings: 6, 4, 3, 2.5, 2, 1.8 and 1 kHz. My radio defaulted to 2.5 kHz, so you’ll want to widen that to 4 or 6 kHz before listening to most broadcasts.

I really like the display–it’s compact, yet contains quite a lot of info and even has a dedicated line for FM RDS content.

This morning, I took a couple shots of the AR-1780 next to the venerable CC Skywave. The Skywave is slightly smaller in every dimension.

Stay tuned! Though this is a very busy week for me–with travels and total solar eclipse preparations–I plan to put the Digitech AR-1780 through the paces. I’ll try to post updates as I have time. Follow the tag: Digitech AR-1780

Radio: “One of history’s most important inventions”

3 Replies

There are few more important inventions in the history of the world than the radio.

While in recent years it may have become less popular than television or the internet, it could be argued that the radio was the first electronic gadget to play a prominent part in people’s lives.

Radio is where the world first heard Britain declare war on Germany, where Orson Welles accidentally fooled the public into believing a real alien invasion was under way in his “War Of The Worlds” serial and where young people first heard Billy Haley’s “Rock Around The Clock,” spreading popular music around the world.

But it is not just an aural medium. Like all important pieces of technology, design has had an essential part to play in its evolution.[…]

(Source: Radio Today UK)

Ten BBC local radio stations will lose at least one AM transmitter in January 2018 as part of the BBC’s Delivering Quality First plan.

BBC Radio Sussex, Surrey, Humberside, Wiltshire, Nottingham, Kent, and Lincolnshire will no longer be accessible on medium wave, whilst BBC Radio Devon, Radio Lancashire and BBC Essex will reduce their frequencies.

The BBC says it knows the changes will have an impact on some listeners but encourages them to listen on FM, DAB, Freeview or online instead.

Video: HF tests from Arecibo observatory

The Arecibo Radio Telescope, at Arecibo, Puerto Rico. At 1000 feet (305 m) across, it is the second largest dish antenna in the world. (Source: Wikipedia)

Many thanks to SWLing Post contributor, Ivan Cholakov, who writes:

Thomas, I did not see a story on the blog about the HF atmospheric heating experiments conducted by the Arecibo observatory a couple of weeks ago.

Thomas Cholakov N1SPY made a video about it but I am also sure a bunch of other listeners were able to tune to the super-strong signal on 5125 and 5095 kHz.

Great video, Thomas!

Indeed, I did miss posting this item. The event timing conflicted with my travel schedule in a bad way. Sadly, I only had one opportunity to tune in and I did too late (by just a couple of minutes!) that day.

Did anyone else catch the on-air experiments from Arecibo?

Radio Caroline at 50 years

Radio Caroline circa 1960’s.

Many thanks to SWLing Post contributor, William Lee, who shares this item from ABC News:

Radio Caroline: Golden age of British pirate radio remembered, 50 years on

They were the pirates of the open seas — bringing rock and pop music to a new generation.

And the British government was furious.

Back in the 1960s, when pop and rock were taking over the music scene, British teenagers had to turn to pirate radio stations to hear bands like the Beatles and the Rolling Stones.

Barred from broadcasting from land, stations such as Radio Caroline and Radio London had taken to the water, using rusty old ships moored in international waters to broadcast to millions of eager listeners across the UK.

The government wasn’t happy and 50 years ago, on August 14 1967, the Marine Offences Act made it illegal to support the ships or broadcast from them.[…]

William note that this story can be found on multiple news sources, but the ABC has more photos.

Many thanks for the tips, William! Like many Post readers, I do love Radio Caroline!
