I remember that article you wrote about Wi-fi radios and just saw this Kickstarter on Facebook that may interest you:

https://www.kickstarter.com/projects/1209003580/mondo

[T]hey are saying it is supposed to ship out sometime next month. [S]ome of the things it has –over the old Mondo–is Bluetooth 4.1 and Chromecast built in.

Thank you, Tom! Here’s the product description from Kickstarter:

The home audio market is evolving, and Grace Digital is leading the way. We combined the latest Wi-Fi audio streaming technologies from Google, added Bluetooth audio streaming, and over 30,000 AM/FM/HD radio stations from around the corner to across the globe. The Grace Mondo+ can even be controlled by the Google Assistant on devices like Google Home, the front panel controls, free smartphone apps, or the included remote control. We wrapped the technology in a beautifully crafted cabinet, and drive the audio with custom made speaker drivers and high performance class D digital amplification, ensuring the best possible listening experience in a perfectly compact design. We hope you love the Mondo+ as much as we do!

This is an “all or nothing” campaign, meaning it’ll have to be fully funded for the production run to become reality.

As a Kickstarter supporter, the pricing is in line with the Grace Digital Mondo (we reviewed last year).

I am still quite happy with my Como Audio Solo, so will not plan to back the Mondo+ at this time. If I was interested, I would splurge for the $174 Early Bird package which includes a Lithium Ion battery pack. Shipping could be as early as April 2017.

Check out full details and a video on Kickstarter.

Thanks, Tom, for the tip! I would certainly welcome a review of the Mondo+ from any Kickstarter backers!

Many thanks to SWLing Post contributor, Ed, who notes:

I just received a status update on the pantronX Titus II portable SDR from Mike, their chief engineer.

Mike said the self-contained SDR portable will include “SoapySDR as the interface to make it much easier to roll your own SDR app.” Here’s some info about SoapySDR:

Engineers devise two-way radio on a single chip

Two-way communication requires, of course, both send and receive capabilities. But putting them in the same device requires a filter between the send and receive circuits to provide signal isolation.

Without a significant filter, communication would be impossible.

“Your transmit signal is [10 to the power 14] times stronger than your receive signal,” said Alyosha Molnar, associate professor of electrical and computer engineering (ECE). “That’s 100 trillion times stronger – that’s a really hard problem.”

But researchers in Molnar’s lab have offered up a solution.

Molnar and collaborator Alyssa Apsel, professor of ECE, have devised a method for both transmitting and receiving a radio signal on a single chip, which ultimately could help change the way wireless communication is done.

Their work is described in “A wideband fully integrated software-defined transceiver for FDD and TDD operation,” published online Jan. 27 in the Institute of Electrical and Electronics Engineers’ Journal of Solid-State Circuits. Doctoral student Hazal Yüksel and Dong Yang, Ph.D. ’15, are co-lead authors.

Separating the send and receive bands is difficult enough, but the problem is compounded by the ever-increasing number of bands in the latest devices. From GPS to Bluetooth to Wi-Fi, each band requires a filter to stop the strong transmit signals from drowning out reception.

Molnar and Apsel have come up with an ingenious way to separate the signals. Their idea lies in the transmitter – actually a series of six subtransmitters all hooked into an artificial transmission line. Each sends its signal at regular intervals, and their individually weighted outputs are programmed so that they combine to produce a radio frequency signal in the forward direction, at the antenna port, while canceling out at the receive port.

The programmability of the individual outputs allows this simultaneous summation and cancellation to be tuned across a wide range of frequencies, and to adjust to signal strength at the antenna.

“In one direction, it’s a filter and you basically get this cancellation,” Apsel said. “And in the other direction, it’s an amplifier.”

“You put the antenna at one end and the amplified signal goes out the antenna, and you put the receiver at the other end and that’s where the nulling happens,” Molnar said. “Your receiver sees the antenna through this wire, the transmission line, but it doesn’t see the transmit signal because it’s canceling itself out at that end.” […]

USB power banks are a convenient way of powering low power USB devices in the field. Unfortunately, as they are designed for charging phones and tablets, many have an internal electronic cut out circuit that switches power off below a certain current draw. The exact current that they switch off at varies from pack to pack.

Although there are circuits on the internet that purport to solve this problem by applying a pulsed load, we found this did not work with all power banks. As a result we designed a neat variable electronic load to address this problem.

Available as a kit, using it is easy; just plug it into your power bank, plug your target device into it and adjust the current draw until the pack remains on.

This could be a handy tool for those of us who use USB battery packs for portable work. SotaBeams originally created this simple kit for the WSPRlite.

The IC-7610 (Source: Icom UK)

Icom Inc. has released more details about the launch of the IC-7610 HF/50MHz SDR Transceiver and its target price. Icom plans to release this high performance HF SDR transceiver around late May with the product being rolled out across the globe in the following months. We expect that the IC-7610 should be available in the UK early Summer with a suggested retail target price of £2,999.99 ex.VAT. Please note that this target price and UK availability may be subject to change.

We expect demand to be huge for this product. Indeed many back orders are already on our system. So if you want to be one of the first customers in the UK to own one of these eagerly awaited radios, please contact your Icom Amateur radio dealer who will be able to put you in their order books.

More about the IC-7610 HF/50 MHz 100 W SDR transceiver

Following on from the technology incorporated into the IC-7300, the IC-7610 adopts the same RF direct sampling system for signal processing. By converting the analogue signal directly to a digital signal and processing it within the FPGA (Field Programmable Gate Array), it provides improved transmission phase noise and excellent RMDR of 105 dB (at 1 kHz detuning).

The IC-7610 will have two independent receivers, enabling simultaneous reception of two frequencies in different bands/different modes.

The IC-7610 will also feature high-speed, high-resolution performance. The real-time spectrum scope supports different bands and a dual display that can monitor different modes. It will also have a waterfall display function that displays received signals in time sequence. The DIGI-SEL unit will be available to both the main side and the sub side of the receiver. In addition, the IC-7610 adopts a large 7-inch full-colour touch screen panel.

Main features include:

• Further evolved RF direct sampling method.
• Excellent RMDR: 105 dB realized.
• Dual watch function can receive simultaneously in different bands and different modes.
• DIGI-SEL unit that eliminates excessively strong signals is installed in the main and sub of the receiving section.
• High-speed real-time spectrum scope and waterfall display function.
• 7-inch full-colour touch panel, outstanding operation and visibility

As mentioned earlier, demand is going to be enormous for this model, so get into contact with your authorised Icom Amateur radio dealer today.

Cross Country Wireless release HF Preselector

Cross Country Wireless have released a HF Preselector.

It is a passive high Q design that does not use an amplifier or external power.

It tunes from 0.5 to 52 MHz.

It is ideal for use with simple SDR receivers like the RTF-SDR dongle with upconverter or SDRPlay. It can also be used with the new receiver socket modification on the IC-7300.

The web page has more details including network analyser plots showing the selectivity of the Preselector.

For your listening pleasure. Here is the best video yet showing the Icom IC-R8600’s Sync Detector in use.

Sounds like Icom “finally” got the Sync Detector performance right with the R8600. Appears to greatly reduce fading distortion, where as with the expensive IC-R9500 it does not help much with fading distortion (if at all).

Good news indeed !!

I agree, Dave. This is most promising indeed!

I look forward to checking out the IC-R8600 at the Dayton Hamvention this year.

Many thanks to SWLing Post contributor, Mike Ladd (with SDRplay) who notes that he has been working on a series of tutorials for operating the SDRuno.

NEW! CC Buds-Pro

Designed and built for voice clarity and less listening fatigue

A recent post from The Wall Street Journal indicates “An estimated 30 million Americans have some degree of hearing loss and the numbers are growing. A study published last month by John Hopkins University researchers, predicted that the number of U.S. adults with hearing loss will nearly double by 2060…”

Buy Two CC Buds Pro and get the Third pair FREE!

I will plan to grab a pair of these in the near future. I keep a pair of the original CC Buds in my Elecraft KX2 go-kit–I find that they’re well-suited for ham radio work and the audio fidelity is quite good for music as well.

I used the original CC Buds on at least 80 National Parks on the Air activations last year. They’re a great choice for sound isolation–more than once I had to set up next to a road and the in-ear buds eliminated all of the noises from passing cars so that I could focus on working pile-ups!

Thanks for the tip, Troy!

Ok, so officially it wasn’t a DXpedition; it was a well needed vacation in the sun after several hectic months of work, some of which involved travel to slightly more exotic locations. However, these days, I view any travel, whether it be for business or pleasure as a ‘DXpedition’ opportunity! Some of you might remember that I purchased a Bonito Boni Whip at the beginning of 2017 because (a) I needed another antenna and (b) a second Wellbrook loop felt like too much of an extravagance. They’re excellent antennas for sure, but at around £300, I couldn’t justify buying another. Thus, for about a third of the price I bought the Boni Whip. It proved to be an excellent choice – very compact and so perfect for my regular DXpeditions, quick to set up and capable of really excellent DX. There are many videos on the Oxford Shortwave Log YouTube channel that are testament to this. I wrote a couple of articles, published here on the SWLing Post which were seen by Dennis Walter of Bonito, who subsequently contacted me and offered to send over their MegActive MA305 E-field antenna for testing. Dennis made it crystal-clear that I was to ‘do my own thing’…test the antenna in any way I saw fit and publish my findings so DXers/radio enthusiasts could learn more about the capabilities of the antenna – from another DXer. I was happy to agree to this arrangement and the MegActive MA305 duly arrived, complete with two lengths of (bayonet BNC terminated) high quality H-155 coaxial cable.

 My portable Dxing kit with MA305 antenna                 The MA305 power inserter and USB power ‘brick’

The specifications of the MegActive MA305 are very similar to the Boni Whip; they both offer a Gain of +3 dBs, second and third order intercept points of greater than +30 and +50 dB respectively and both tune to 300 MHz. The MA305 is supplied with a longer radiating element and tunes down to 9 KHz (versus the 20 kHz lower limit for the Boni Whip). Obviously this isn’t a specification that is going to concern most radio enthusiasts; both offer fantastically wide operating bandwidths. The way in which these antennas do differ quite significantly however, is in how they are powered. The Boni Whip operates from 12 to 15 V, whilst the MA305 operates from 5 to 15 V. Bonito’s design philosophy regarding this feature is based on the increasing difficulty in procuring reasonably priced analogue external plug-in power supplies (they are no longer allowed to be produced due to power consumption restrictions).

Interestingly, when the power supply for my Wellbrook ALA1530 packed up, I called them to purchase a replacement and was told they only have limited stocks remaining. Thus, a solution for powering active antennas with a suitable low-noise supply is an issue that needs resolving. The guys at Bonito figured a USB power source was suitably quiet and with USB ‘power bricks’ almost ubiquitous these days for charging mobile phones and other portable electronic devices on-the-go, the idea could be applied to their active antennas. The result is the MegActive MA305, designed to operate at 5 Volts with no loss of performance. As a DXer who probably spends more time listening on DXpeditions than I do in my shack at home, the USB power solution was perfect. I myself often carry a cheap Chromebook laptop to use as an additional power source for my camera phone when I’m DXing, so Bonito’s design approach resonated with me completely.

Travelling with the MegActive MA305

Ok, so the MA305 is very compact and very light indeed – perfect for a trip to Crete! However, I know from many conversations with my YouTube friends and followers that some of us feel a slight sense of trepidation carrying shortwave radios and antenna systems on board flights, be they national or international. I myself wasn’t really concerned other than if my bag got pulled from the X-ray machine, there’s often quite a long wait whilst the security staff work through the queue of luggage requiring er…human intervention! Predictably, my rucksack did get pulled and I waited patiently until it was my turn to explain the contents! Looking back on this retrospectively, it’s hardly surprising. Other than the usual holiday paraphernalia, my rucksack contained:

• A 10.0 metre length of H-155 coaxial cable
• A 1.0 metre length of H-155 coaxial cable
• Eton Satellit receiver
• MA305 Coaxial Power Inserter
• MA305 Antenna Amplifier
• Bonito USB ‘Power Brick’
• Bonito USB Power Cable
• NooElec RTL-SDR dongle
• NooElect ‘Ham It Up’ upconverter
• Various screened cables and connectors
• 10 metres of equipment wire

I explained to the (friendly) security chap that I was a shortwave radio hobbyist and identified the various pieces of equipment for him, as he removed them from my rucksack. He confirmed my X-ray had ‘lit up’ (in blue as it happens) with metallic/electronic items and was even kind enough to swivel his monitor to show me the mess of items strewn across the screen – just as I had thrown them all into my rucksack! However, after quickly swabbing some of the items, he said all was fine and hoped that I enjoyed my holiday and listening. Service with a smile at Gatwick Airport – and I was on my way. My outbound experience got me thinking whether it would be possible to pack my DXing kit in such a way that it wouldn’t alarm airport security. Thus, for the trip home, I packed all of my cables into my (checked-in) suitcase. I figured it would be obvious there was no security risk associated with cables alone. I then packed my RTL-SDR, upconverter and all of the MS305 components very neatly into a single box and put that in my carry-on rucksack. Now, some might argue that security measures at Heraklion International Airport in Crete differ a little from London Gatwick, but I observed staff at the X-ray machine very carefully monitoring every piece of luggage passing through it – including my own and I passed straight through without a problem. All I did was take my laptop out as usual, and put it in a separate tray. Job done.

DXing with the MegActive MA305

                                      My listening post in Crete, with the brilliant Eton Satellit receiver

My apartment in Crete was on the second floor and a large balcony provided a decent outdoor location for DXing. As regards electrical noise, the location was much quieter than my shack at home, but it certainly wasn’t perfect, thus a good test of the MA305 in a real-world pseudo-urban environment. in an attempt to improve SNR, I bought a cheap ‘Selfie Stick’ and some tape and managed to construct a mount for the amplifier, increasing the overall height above ground by about 1.5 metres and displacing the radiating element an additional 2 metres thereabouts from the building. I’m not sure whether it made much difference, but it seemed like the sensible thing to do for less than 10 Euros.

During my week-long stay, I managed to fit in several listening sessions and copied some really excellent DX from this ultra-compact, USB-powered set up. In fact, the MA305 coupled to the Eton Satellit performed so well, I managed to copy a number of personal firsts, including CRI on 7295 kHz, via their relay in Bamako, Mali, The Voice of Beibu Radio on 5050 kHz, Nanning, XSL ‘Slot Machine’ on 6251 kHz USB, Ichihara, Japan, S32 ‘The Squeaky Wheel’ on 3828 kHz and NHK World Radio Japan, 11910 kHz. I also copied RTM Wai/Limbang FM on 11665 kHz from Kajang, Myanmar Radio on 5985 kHz and AIR Bhopal on 4810 kHz, amongst others – all of which I would certainly consider to be difficult catches in Europe. To hear them with an 18 cm antenna felt pretty special. African shortwave stations were also very well represented and I managed to copy a number of them including Radio Hargeysa on 7120 kHz, Voice of Tigray Revolution on 59150 kHz, Radio Oromiya on 6030 kHz, Radio Fana on 6110 kHz, Radio Ethiopia on 7235 kHz, Radio Sonder Grense on 3320 kHz and Radio Guinée on 9650 kHz. I expected to hear all of these stations, except for Radio Guinée, which is farther away from Crete than the UK. So, all-in-all an excellent result.

Despite hearing a lot of excellent DX whilst in Crete, there is one signal I copied, which more than any other, demonstrates the DXing credentials of the MA305 – and Eton Satellit for that matter. In the early hours of the morning (00:59 hrs UTC) I copied and recorded Radio Tarma from Peru on 4775 kHz. With a TX power of 1 kW, this is a very difficult station to hear in Western Europe, even with a longwire. To catch this station in Crete, at all, was incredible on an ultra-compact set-up. It was at this point during the trip that I realised E-field antennas really do work superbly well for hard-core DXers on the move. It inspired me to conduct further tests back home in the Oxfordshire countryside, where electrical noise is absent. This I did a few days ago, with some quite amazing results on the Tropical Band. More on that to come in my next post. In the meantime, please find text links and embedded videos for selected reception recordings, below. Many more recordings are available on the Oxford Shortwave Log YouTube channel and please don’t hesitate to contact me if you require further information on the MA305 or the Eton Satellit. Thanks for reading/watching/listening and I wish you all excellent DX.

This radio seems to have recently been released in Oz, no idea of its performance on SSB et al. but seems to do everything the C.Crane Skywave does. Heavy on batteries though at 4 x AA and nearly twice as heavy with similar dimensions to the Skywave, not major if it performs well and has good battery life.

Apparently the AR-1780 uses the SiLabs DSP chipset going by comments on Radio Reference. Also has RDS, Temp, the keypad layout looks similar to a Eton G3.

Taken from Jaycar’s website site:

This is a very compact world band radio, covering the most popular frequencies. It features rapid digital tuning, 1000 memory presets, and an easy to read display. Single Sideband Modulation (SSB) is used to listen in on 27MHz CB radio, short wave amateur radio and morse code. The large internal speaker provides clear audio, and you can connect your favourite set of headphones for personal listening. Powerful enough to receive what you want, and compact enough to take wherever you want.

Features:
– FM/MW/SW/LW/AIR Bands
– Single Side Band (SSB)
– Telescopic Antenna
– 3.5mm socket for external antenna
– Selectable Bandwidth: 1 – 6kHz

Specifications:
Radio Bands:
FM 87.5 – 108MHz
MW 522 – 1620kHz / 520 – 1710 kHz

This looks like a full-featured portable. As mentioned, it certainly resembles the Grundig G3 in many respects.

If the AR-1780 performs well, it’ll be a very welcome addition to the Australia and New Zealand markets.

Please contact me if you’ve purchased the AR-1780 and would like to write a guest post/review. I’m very curious how well this portable stacks up against other portables especially in terms of overall sensitivity/selectivity and noise floor.

The new Icom IC-8600 at the 2017 Hamvention

At the 2017 Hamvention, I spent a little time checking out Icom’s latest wideband communications receiver: the IC-R8600. Check out the photos above and below.

The IC-8600 Back Panel

I spoke with Icom North America at Hamvention–the representative told me the MSRP of the IC-R8600 would be about $2,999 US, but that retail pricing would be lower.

Universal Radio now has the IC-R8600 in stock with a retail price of $2599 US. HRO has the IC-R8600 in stock as well and selling for the same price.

No doubt, at this price point, the ‘8600 is not ideally placed to compete with other receivers and SDRs. I do, however, believe this product will do well with government sales. No doubt, it should deliver benchmark performance (at least one would expect benchmark). Icom has offered to send me an IC-R8600 on loan for a review–it is tempting to see how it might stack up against some of my SDR arsenal.

I’m very curious Post readers: assuming benchmark performance, how many of you would purchase the IC-R8600 at $2,599 US? Please comment!
