The Como Audio Amico and Musica via Kickstarter

The Como Audio Amico

Many thanks to SWLing Post contributor, Tom Ally, who writes:

Saw this and wanted you to know about it since you mentioned loving his past Kickstarter [for the Solo WiFi radio].

I backed the Musica model instead of the Amico since it still has 18 days left and it had a CD player in it but thought you would like the portable Amico

Thanks for the tip, Tom!

If I didn’t already own the Como Audio Solo, I would grab the Amico. It appears to be nearly identical to the Solo–save, in a vertical orientation–and includes an internal rechargeable battery option.

Here’s a full list of its specifications and features:

Multi-room: play different sources in every room or sync them all together
Internet radio accessing 30,000+ stations
Spotify
Bluetooth with aptX
High performance FM Tuner
DAB+ (International version only) – DAB+ upgrade and VAT is included in shipping cost
NFC Android Bluetooth connection
DLNA WIFI Music player allowing easy navigation and playback through a USB or network-shared library of music files including AAC+, MP3, WMA, WAV, and FLAC
High-Res inputs: 1 analog and 1 USB
Dual alarm clock functionality
Snooze function
Sleep Timer
2 X 30 watt RMS amplifier, <1% THD
3″ woofer with four layer voice coil
3/4″ dome tweeter
Independent Remote Control
Universal Switching Power Supply 110-240V

I continue to be very pleased with my Como Audio Solo–it pretty much lives in my radio shack and I use it daily to catch up on my favorite news and music sources. I distribute the Solo’s audio throughout the house with my SSTRAN AMT3000 AM transmitter–admittedly, an old school version of Como’s “multi-room audio sync”–!

When I need a battery-powered portable WiFi radio these days, I read for my Sangean WFR-28–thus, the Amico would be a pretty pricey impulse purchase for me at this point!

The Como Audio Musica

I find it fascinating Como has also introduced the Musica model which includes a CD player–somewhat of a unique feature in 2017.

Here are the Musica specifications and features:

Multi-Room: play different sources in every room or sync them all together
Internet radio accessing 30,000+ stations
Integrated music streaming services: Spotify, Tidal, Deezer, Napster, Amazon Music* (*Available Winter 2017)
On-board single slot-loading CD player engineered to meet stringent car audio standards
Supported CD formats: CD, CD-R, CD-RW/MP3/WMA
Bluetooth with aptX & AAC
High performance FM Tuner
DAB+ (International version only) – DAB+ upgrade and VAT is included in shipping cost
NFC Android Bluetooth connection
DLNA WIFI Music player allowing easy navigation and playback through a USB or network-shared library of music files including AAC+, MP3, WMA, WAV, and FLAC
Ethernet connection
High-Res inputs: 2 analog, 1 optical
Dual alarm clock functionality
Snooze function
Sleep Timer
2 X 30 watt RMS amplifier, <1% THD
2 X 3″ woofer with four layer voice coil
2 X 3/4″ dome tweeter
Independent Remote Control
Universal Switching Power Supply 110-240V
Dimensions: 405 mm W x 143 mm H x 165.5mm D (including antenna)
Weight: 9.3 lbs, 4.21 kg

I still have (quite literally) hundreds of CDs. While many have been converted to AAC and MP3 formats, there’s still something to be said for CD audio fidelity and enjoying a proper album format.

If you’ve been thinking about purchasing a Como Audio device, you might consider the new Amico and Musica via Como’s Kickstarter campaign.

Cornell engineers invent two-way radio on a single chip

Many thanks to SWLing Post contributor, Tom Ally, who shares the following news via the Cornell Chronicle:

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.” […]

Grace Digital Mondo+ Kickstarter

Many thanks to SWLing Post contributor, Tom Ally, who writes:

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, Tom Ally, for sharing the following article by James Careless in Radio World:

Well, if you are the engineering firm PantronX, you have the Titus II software-defined radio. And when you plan to sell this ultimate receiver for less than $100 each, you hope you have a consumer sensation for the worldwide broadcast market.

Unveiled by the Panama-based company at an international broadcasting meeting in Miami in August, the Titus II SDR is not yet shipping. But it is described as capable of receiving and playing analog and digital radio transmission formats including AM, FM, shortwave, HD Radio, DAB+ and Digital Radio Mondiale. The company is considering adding a DRM+ decoder.

The initial market is among worldwide broadcasters, particularly those serving countries where listeners may lack internet; a secondary market is individual listeners, hobbyists and others. PantronX will not supply all decoders for all formats but add them preloaded as needed.
