Titus II Expression of Interest Form Available Now

Earlier in the month we posted about the Titus II SDR. The Titus II is an upcoming full SDR solution, including a wideband 100 kHz to 2 GHz SDR, Android tablet with touchscreen and speakers. They write that the price will be under $100 USD.

The High Frequency Co-Ordination Conference (HFCC) is a group active in informal co-ordination of frequency channels used in short wave broadcasting. The HFCC appear to be helping with the release of the Titus II, and they now have an online expression of interest form available on their Titus II page. The form is labelled “Pre-order”, but there is no payment or contract present, so it is more like an expression of interest. They write:

The Titus II – an Android tablet computer with wideband SDR receiver – was unveiled for the first time at the B16 HFCC/ASBU conference in Miami, Florida, 22-26 August 2016.

The receiver has been the result of cooperation between Trans World Radio (TWR) and PantronX.

The HFCC is assisting in collecting the demand/pre-orders.

Availability: Pre-production batch – 4Q/2016, regular production – 1Q/2017

Price: Under 100USD plus shipping and local duty/taxes not included

Payment methods: Wire transfer for larger quantities, PayPal works too, but the buyers would need to add PayPal bank fees

An initial order sufficient to start the production has already been placed and production will start irrespective of the amount pre-ordered via this page. Pre-order is not binding and you are NOT asked to send any advanced payment or credit card number to secure the pre-order.

The Titus II Complete SDR Solution

Recently we’ve heard news of a new portable SDR called the PantronX Titus II which is currently in development. The receiver is a full SDR solution, including the computer, speakers, antenna and SDR all in a single boombox styled enclosure. The computer appears to be based on an Android tablet, and comes with a Quad-core ARM A53 @ 1.2 GHz CPU, 1 GB RAM, 8 GB Flash memory, 7″ TFT screen, touch screen, 5 watt stereo audio, li-poly battery. HDMI output, microUSB OTG connector, WiFI/Bluetooth connectivitiy as well as having an optional camera. 

The frequency range extends from 100 kHz to 2 GHz, and the built in software is capable of decoding AM/FM/SSB and DRM. Since it is essentially an SDR with an Android tablet, it should also be capable of decoding any other signal, as long as software decoders are written for it. We are unsure what SDR is used on the inside, but judging by its frequency range we speculate that it may be the same Mirics chips that are used inside the SDRplay RSP.

Rumour currently has it from word of mouth of the developers that this unit will priced “well below $100 USD”.

Wavesink Plus: Android RTL-SDR App with FM+RDS/DAB+/DRM+ Decoding

Wavesink Plus, the paid version of the trial version of Wavesink has been released on Google Play. Wavesink Plus is an Android app which has FM+RDS, DAB+ and DRM+ receiving and decoding capabilities when connected to an RTL-SDR dongle via a USB OTG cable.

We gave Wavesink Plus a test today on a HTC One X Android phone and were pleased to discover that it works perfectly. The user interface has been tidied up from previous versions, and DAB+ has been added. There is now also auto tuning functionality, which will automatically find a station.

In further testing we found that the latest version of Wavesink was fast and snappy and was able to load DAB+ stations quickly, and decode them with clear audio. FM radio also sounded clear and RDS information loaded quickly as well.

Tutorial: HF Decoding Tour with the FUNcube Dongle Pro+

On the FUNcube Dongle blog/store amateur radio enthusiast DK80K (a.k.a Nils) has sent in a link to a 16 page pdf file showing a comprehensive tour on the FUNcube Dongle Pro+’s capabilities on the HF spectrum.

He gives an overview of many digital ham and HF utility modes including DRM, WSPR, RTTY, Olivia, MFSK16, PSK31, Pactor, Packet, Hellschreiben, ROS, SSTV, HF ACARS, SSB, CW, DSC/GMDSS, SITOR-A/B, Globe Wireless, Time Signals, ALE, Baudot, FAX and Stanag 4285.

The FUNcube is a software defined radio similar to the RTL-SDR, but with better sensitivity and noise performance, but at a higher price (around $200 USD). These modes can also be received with the RTL-SDR and an upconverter such as the Nooelec Ham-It-Up upconverter.

RTL-SDR Tutorial: Decoding DRM Radio

Digital Radio Monodial (DRM) radio is a type of digital shortwave radio signal that is used by international shortwave radio broadcasters. It provides superior audio quality compared to AM signals by using digital audio encoding. With an upconverter, good antenna, and decoding software the RTL-SDR software defined radio can receive and decode DRM signals. This tutorial is also applicable to other software defined radios that can receive HF with or without an upconverter, such as the HackRF, Airspy, Softrock and Funcube dongle.
