The DX-Patrol MK2 is a compact software defined radio receiver featuring a “Ultra wide” receiving frequency range. This is made possible because this receiver
includes a converter for HF bands
with additional band filters, resulting in a much better dynamic range and an excellent performance in strong signal processing.
Operating on HF bands need a frequency shift of -40MHz. DX Patrol SDR offer the entire frequency range without gaps.
It features two indipendent SMA antenna connectors, one for VHF and one for HF bands and a Mini USB port as PC interface.
The switch on the side of the receiver permit the use of a low-noise pin diode, to be used when changing from HF to VHF bands or vice versa. Sampling rate supported by the SDR is 3.2MS/s, but this is usually limited by the PC software.

The current MK2 version has better performance due to its optimized filter circuit and brand new RF design.

SDRplay is pleased to announce the official release of SDRuno for the RSP.
SDRuno is the new name for the RSP compatible version of Studio1, the rights to which we obtained and announced on 28th April.
SDRuno contains native support for the SDRplay RSP and no extra plugins are required. Third party hardware can also be supported via the ExtIO interface, but with reduced functionality.
SDRuno provides a rugged and flexible, high performance SDR receiver capability and boasts some excellent features:
• Multiple ‘Virtual Receivers’ which allow for simultaneous reception and demodulation of different types of signals within the same receiver bandwidth.
• A selectivity filter with an ultimate rejection greater than 140 dB.
• A unique distortion-free double stage AGC with fully adjustable parameters.
• Multiple notch filters with BW adjustable down to 1 Hz, Notch Lock feature.
• A unique synchronous AM mode with selectable/adjustable sidebands, dedicated PLL input filter, and selectable PLL time constants.
• SNR (stereo noise reduction), featuring a proprietary noise reduction algorithm for stereo broadcast.
• AFC for FM signals.
• Calibration for receiver frequency errors.
Over time, we plan to add many more features to SDRuno to enhance the user’s experience of this very powerful piece of software. This software runs on Windows and we don’t yet know how easy it will be to migrate it to other platforms but this is something we will be investigating.
SDRuno will be made freely available to all current and future users of the RSP – to download a copy of both the software and the documentation – simply go to http://www.sdrplay.com/windows.html
Our support for SDRuno in no way lessens our commitment to support HDSDR, SDR Console, Cubic SDR or ANY other software solution where the authors are willing to work with us. We fully recognise that many people have strong preferences for particular pieces of software and we do not want to do anything to undermine the options that people have to use their favoured software packages. Indeed, our view is quite the opposite.
Our objective remains aim to have our hardware platforms support any and every SDR package out there. This of course may not be possible, but it is our philosophy and part of the ethos of our company.
What is the RSP?
The RSP (Radio Spectrum Processor) from SDRplay is a Software Defined Radio which can turn a PC into a general coverage receiver spanning VLF (10KHz) through to Microwaves (2GHz)
About Studio 1:
Studio1 was developed in Italy by SDR Applications S.a.s. and has hundreds of happy customers around the world. Studio 1 is known for its user friendly stylish GUI, CPU efficiency and advanced DSP capabilities, including features not available on other SDR software packages.

Not many HAM radio programs do already support the IC-7300. As far as CAT commands, the IC-7300 seems to be compatible with older radios like the IC-7700. Here’s a description of setting up your IC-7300 radio to work with the last freeware version of Ham Radio Deluxe (5.24).
The problem originates by improper TXOUT-to-RF timing (RF transmission exists still after a TX-EN prohibition), combined by too long decay of their CW pulses.

During the last Dayton Hamvention, SDR Play announced their new high perfomance SDR receiver, the RSPduo, a 14-bit dual tuner that looks estetically similar to the previous SDRPlay products, but is radically new from the architectural point of view.
RSPduo
The RSPduo is a radical new addition to the RSP line of SDR receivers from SDRplay. Architecturally, it is different from any previous RSP in that it features dual independent tuners, both piped through a single high-speed USB 2.0 interface.
The SDRplay RSPduo is a dual-tuner wideband full featured 14-bit SDR which covers the entire RF spectrum from 1kHz to 2GHz giving 10MHz of spectrum visibility. Initially using Windows based ‘SDRuno’ supplied by SDRplay, you can simultaneously monitor two completely separate 2MHz bands of spectrum anywhere between 1kHz and 2GHz.
The RSPduo dual tuner
Superficially the RSPduo looks identical to the highly popular RSP2pro and will be able to operate in a very similar way. However, it also allows a completely new and exciting set of usage scenarios such as:
1. Simultaneous monitoring of two widely spaced bands – e.g. 40m (HF) and 2m (VHF)
2. Mixing and matching applications simultaneously – e.g. ADS-B and ATC scanning
3. Phase and time coherent demodulation of two receivers
Scenario 3 is very difficult to achieve with two separate USB devices because of the uncertainty of USB latency. The RSPduo overcomes this limitation because all traffic goes through a single USB interface, thus enabling the possibility of the development of various types of diversity demodulation such as: spatial, frequency and polarisation which can bring huge benefits in terms of improved performance.
As well as adding a second independently controlled tuner, which in itself, offers a whole new set of exciting usage possibilities, the SDRduo features 14bit ADCs and a completely re-designed RF front end. These changes provide better RF selectivity and even more dynamic range, offering outstanding performance under extremely challenging reception conditions. The combination of performance and features makes the RSPduo our highest spec RSP yet and sets a new benchmark in the sub $300 SDR market.
Lots of great new videos are appearing on YouTube showing the Dual Tuner RSPduo in use.

SwissUnit is an automatic antenna relay for one transceiver and one receiver on the same antenna.
The use of an SDR with a traditional HF receive is a nice enhancement of any amateur radio station. With suitable software the transceiver can be controlled by the SDR interface. This brings new life to any older radios by adding an up-to-date waterfall feature. But often you face the question, where to get the antenna signal from. Not every transceiver offers an antenna monitor output. What to do?
This is exactly the issue the Swiss made “SwissUnit” addresses. Swiss Unit is the combination of an antenna splitter with an antenna relay and the required controller electronics.
When receiving the antenna signal is split up to both – the transceiver and the SDR receiver. You can use the received signal on both systems, on the radio and on the computer. When switching to transmit mode the relay cuts off the SDR branch of the splitter and the antenna is directly connected to the transceiver. This protects the receiver input of the SDR. As a result you get a very comfortable system with up-to-date SDR reception and waterfall, and your trusted transmitter from the existing radio.
At the same time as switching the HF signal, the SwissUnit also switches an audio signal. This is used to cut off the audio signal coming from the SDR via the computer soundcard to the speaker system, to prevent audio feedback when transmitting. The supplied switching electronics box takes the PTT signal and supply voltage from the transceiver and switches the relays when going to transmit. The signaling is very simple, a cable can be homemade within a few minutes. Practically any transceiver can be used.
The HF relay and splitter is a qualit product with excellent specifications, which can switch up to 100W power. The splitter is specified up to 400 MHz, but can be used up to the 70cm band without too much losses. The antenna connectors are N sockets, the radio side uses BNC sockets. The control cable from the transceiver uses a 4 pin rund Foster type connector, as it is found on microphones as well.
A control cable radio to use with the FT-991/A is offered as well, other transceiver cables are planned. But it is very easy to make a cable on your own, the required connector is supplied
