Frank reports on the Deshibo RD1860BT portable shortwave receiver

Many thanks to SWLing Post contributor, Frank, in Germany, who shares the following guest post and review of the Deshibo RD1860BT:


Deshibo RD1860BT report

Hello Thomas,

Today I would like to report on a new portable world receiver. Unfortunately, new devices have not been found on the shelves of electronics retailers for a long time, but now in the depths of the world wide web. And that’s how I came across the Deshibo RD1860BT.

Deshibo is certainly known to many from their GA450 loop antenna. But Deshibo has also produced several radios, including the RD1780L, which is probably a little better known. New to the segment is the RD1860BT, which initially seemed like an old friend to me. An Eton Elite Executive? Yes, there are external similarities, but also differences.

Many months ago I had an Eton Elite Executive for a short time. I had heard of its excellent reception properties, which I can confirm, but the design is reminiscent of older receivers from the 80s, is relatively heavy, operation is sometimes a bit cumbersome, the protective cover does not protect properly. I find the device to be portable overall difficult. We didn’t become friends, so I sold it on to a Swede, who in turn became a friend.

I still missed the Eton. RDS on VHF is not found in any Tecsun , nor are there memory banks that can be written on.

Then I discovered the RD1860BT and couldn’t resist. First of all: the Deshibo is only labeled in Chinese for important function keys. But the friendly dealer on eBay provided me with an English manual before I bought it. That was the deciding factor, because I was sure that after a little use , the Deshibo could be operated blindly.

However, some questions have arisen in the user manual. Some things didn’t seem quite right, others were completely missing from the description. That’s why I decided to write my own manual on a journey of discovery of the new Deshibo. And so that it might also help others who might be interested in radio, I wrote it in English and attach it here.

The Eton’s somewhat unsorted manual was very helpful, but I also added my own drawings. For example, I added an English-labeled keyboard as a back cover, so that the keys can be assigned without a long search.

Here you can already find the first differences to the Eton: the keyboard layout is a bit more orderly. Also, the Deshibo doesn’t have a metallic speaker grille (which frankly I don’t like about the Eton). The display, not the writing, is backlit in orange on the Deshibo . Most importantly, the Deshibo is a lot lighter than the Eton ( around 500g if I researched correctly). And that means: the structure of the Deshibo must be different. Continue reading

Carlos’ Shortwave Art and recording of the Voice of Korea (November 4, 2022)

Carlos notes:

Part of news bulletin from Voice of Korea Radio, 12015 kHz, broadcasting in English from Kujang, North Korea, and listened in Porto Alegre, Brazil, November 4, 2022, 21h (UTC).

“Press Statement of Pak Jong Chon, Secretary of the Central Committee of the Workers’ Party of Korea

It is reported that the United States and south Korea have decided to prolong the “Vigilant Storm” joint air drill.

It is a very dangerous and wrong option.

The irresponsible decision of the United States and south Korea drives the present situation created by the provocative military action of the allied forces to an uncontrollable situation.

The United States and south Korea will come to know that they made irretrievable terrible mistake.

Do you use a general coverage transceiver as your primary shortwave radio?

If you’ve been reading the SWLing Post for long, you’ll know that I think the Icom IC-705 is a brilliant radio for shortwave, mediumwave and even FM DXing. I mention this in my IC-705 review.

Indeed, I realize that I may even use the IC-705 as much as I use some of my excellent computer-connected SDRSs (Software Defined Radios). The IC-705 is actually an SDR, too, just one that is self-contained, stand-alone, and powered by a rechargeable battery. It’s just so convenient and easy to use–plus it has very useful built-in recording/playback functions.

I also use my Elecraft KX2 for SWLing–although not designed for broadcast band listening, it does a pretty amazing job especially if your primary goal is weak-signal work. Elecraft attenuated the mediumwave band on purpose, thus MW DXing with the KX2 is not feasible.

Do you use general coverage transceivers for SWLing?

Truth is, modern general coverage transceivers tend to be based on SDR architecture these days, thus incredibly capable and versatile as a broadcast band receivers.

I’m curious: do you primarily use a general coverage transceiver for SWLing? If so, why and which make/model? Please comment! If you prefer a dedicated receiver over a general coverage transceiver, please consider sharing your thoughts as well!

Which radio? How to avoid analysis paralysis…

I’ve been running the SWLing Post for fourteen years (!!!) and during that time I’d say that one of the top three questions I receive is a variation of “Which radio is better?” followed by a list of radio makes and models.

Sometimes that question is easy to answer because the reader is new to the world of shortwave, they only have two choices, and one is an obvious winner.

In truth, though, that’s very rare.

Most of the time–and I’m speaking from having received hundreds of these questions–I’m asked to choose between a list of radios that the reader has thoroughly researched, uncovering radios DXers and enthusiasts consider to be the best in price class.

They’ve already read numerous reviews, created spreadsheets comparing features/specifications, and they’ve weighed all of the pros and cons by price class.

But they can’t decide.

Analysis paralysis

We’ve all been there, right?

We’re ready to invest a bit of money in a new radio and there are many good options, but there’s no one stand-out…no “perfect” radio with everything we seek.

It’s a slippery slope.  We start our research with some obvious choices. We can’t decide which is best, so we broaden our research, we take deeper and deeper dives, but the more we research, the more confused we become.

Sound familiar? (Trust me: you’re not alone.)

I remember receiving an email once from someone with a list of two dozen sub $150 radios on a multi-tab spreadsheet.They had every feature and specification listed for comparison. They wanted to know which of these radios was “the best.”

I can’t answer this questions for a very good reason.

It’s all about personal preference

My favorite radio from a list of twenty four will likely not be your favorite radio.

Enjoyment of a radio has everything to do with you as the radio’s operator.

Ask yourself, “What’s my main goal–?”:

  • DXing?
  • Weak signal work?
  • Band-scanning?
  • Pirate Radio hunting?
  • Travel?
  • Emergency communications?
  • Casual broadcast listening?
  • Digital mode decoding?
  • Scanning?
  • Mediumwave DXing?

Look at your options with this goal being given the priority.

A rather simple way to avoid analysis paralysis

If you’ve thoroughly researched multiple options, the likelihood is that overall performance between the models is comparable. Sure, some models might have better AGC, better sync, finer tuning, a better encoder, or better sensitivity, etc. but the overall performance package is similar else there’d be no difficult decision to make.

My advice is to pick the radio that you believe you’d enjoy the most.

  • Do you like the display and large encoder on one? Does it look like the sort of radio you could cuddle up to late into a cold winter evening? Go for it!
  • Do you like the compact size and features of one? Does it look like a radio you could pack away for an international flight then use on a mini DXpedition in a foreign country? Grab it!
  • Do you like the comments you’ve read about the robust audio and speaker of a particular model? Pull the trigger!

I’ve been communicating with a reader over the past few days that is stuck in analysis paralysis. No doubt, this is what prompted this post.

Here’s what I told him this morning:

All of the models we’ve discussed are good ones and have overall excellent performance. I would simply pick the one you think you would enjoy using the most.

[Keep in mind that] DXing is a skill.

A skilled DXer can accomplish a lot with almost any radio! It’s easy to fall in the trap of options overload. Just find a good deal on a radio you think you would enjoy and go for it! 

I suppose another way of stating it would be if you believe you’re stuck in analysis paralysis, follow your heart instead of your head.

Sometimes the right tools lead to agreeable results

Listening to the HF ham bands can be a lot of fun. All you need is a shortwave receiver capable of receiving single sideband (SSB) transmissions and a chart of the amateur bands. You can find downloadable PDF charts of the United States Amateur Radio Band Plan here or a detailed explanation of the band plan here.

Tuning around to hear what people are talking about can be enlightening.  You might hear hams chatting about ham radio equipment, house repair projects, religious discussions, news and views or the state of the country, disaster response communications, or almost anything.

Recently I was tuning through the 80 meter ham band when, at 3605 LSB, I encountered a group having a conversation. I couldn’t tell if this group had a formal “Net” name, but I did get the impression that they met regularly in the early morning on that frequency, so I made a note to revisit the frequency.

Yesterday, I did so. With the horizontal room loop hooked to my Grundig Satellit 800, all I could hear was noise. The same with the whip antenna on the Satellit 800.

But when I engaged the MFJ 1886 loop antenna I could clearly hear the group talking above the noise . . . but the noise was still pretty bad. So I tried bringing the MFJ 1045C active preselector online, to no avail. The 1045C did not make the conversation easier to hear.

The noise was like a hum, not a nice gentle hum like a bumble bee flying by; no this was a nasty, raspy hum, like a circular saw trying to get purchase on a particularly tough piece of wood. Listening to the chat group on 80 meters with that noise under it would be tiring on the ears.

Soooo, what to do? Then I plugged in the BHI Compact In-line Noise Eliminating Module into the headphone socket of the Satellit 800 and then plug headphones into the BHI device.

Turning on the BHI module, I adjusted the level of noise reduction, and – tah dah! – the noise just melted away. I could hear the conversation clearly, and all that was left of the noise was the trickling water sound that is an artifact of the noise reduction algorithm.

Sometimes, the right gear just works.
