Are Citrus Fruits Bad For The Heart

All together .... passionate

Today I wanted to put "under pressure" on my PC, an "old" Core Duo QUAD almost 2 years. What better way than to make it work in an extreme condition with my SDR?
So in the picture below, you can see a better two pair of applications running simultaneously on my PC:
  • PowerSDR on FLEX-5000 to 7035Khz
  • DM780 Superbrowser PSK31 mode, connected to VAC2 PowerSDR
  • PERSEUS DRM mode 250Ks / S DREAM
  • TDP in RADIO decoding, connected to VAC1 PERSEUS
  • Tmate tuning PowerSDR Virtual Serial Port
Well even with all these "heavy" applications, the system ran at no more 30% of the CPU, as you can see by the indicator in the dialog Tmate.


Even in these difficult conditions the various programs are working properly and, thinking that the time covered by the image of several audio channels (well 3) and data streams from Firewire (Flex) and USB2 (PERSEUS) in addition to handling all the graphics in time real (panadapter waterfall and several) the system (thanks to the goodness of the code of the software) is holding very well.

Where To Buy Nembutal In Singapore

Little Shop of Horrors














Cold Blood (The Tempest)
(the disk in question can be found around the 30 October)
A little 'as the Bloody Beetroots and elective affinities and iconoclastic, this second chapter in the saga of The Little Shop of Horrors was agonizing wait. Here, too many miles, but typically around Italy to move hearts and guts, brains and atrophied eyes off. Spitting in the form of rock rock and liberating words of anguish and absolute love. Well, the miracle is repeated. Renovated in intent and form. Game time is eaten raw, grinding his teeth in the eddies of bile dormant for too long. The wall of sound is even more surgically cured and produced by the meticulous work of Ragno Favero and Pierpaolo Capovilla's words are pregnant with ideas, anger, love, despair and whirling poetic context. The maturity of the second disc here it is all flat-spotted his face to the sound of screams and spits argue, melodic sound walls and proclamations through clenched teeth. It starts calmly, directly from that closed larsen "In the Empire of Darkness", just annoyed and suspicious glare. But this time the mistake is substantial, and after the weak "I'm waiting for you" part immediately first cartoon in the belly. "Two" bleeding from the opening riff of guitar noise and dirt. Determination as to whether this will rarely observed. And here is a thought that Little Shop of Horrors is planting roots in a place already implemented by other fondamenetali Italian rock band, from CCCP to tribal rhythms, by up to Afterhours Verdena. The Italian rock today, that this is the fucking year zero, to be attached to envy and inspiration to that of Vasco Brondi and its lights of the Power Station. We want to see side by side at the next feast of International! And the circle is closed, why not mention Bob Rifo beginning was just to make propaganda, but because Bob is also in here, acting synthetic "Directions Several "where there is dancing, yes, chased and running away in the rain and mud, with a melancholy dirge on his head. And that absolutely no one expected it. As no one expected an album of immense and even better ' onset, because it offers a rock machine that can still amaze and thrill like few.

Jumped Into Pool And Jammed Knee

The Bloody Beetroots





















Romborama
(Universal)
E finally arrived. After miles of touring around the world, in decibels burned bodies and ears of millions of young clubbers and gallons of sweat under those masks superhero Rifo bad here that Bob brings a gift to contemporary music, his opus maximus. Since the high-sounding title and roaring, deafening and cumbersome. It must be said, "Romborama", like it or not like the Bloody Beetroots, is an important disc. Why is the low and low distortion of Bassano del Grappa of that "punk with an attitude" that is Bob Rifo, fine mind that for years and then whisk in wine clubs and attached to the computer to break something. The wall of indifference towards the international Italian music, the wall of the Italo Disco and cult prog as unique musical forms "quality" of our country universally recognized, the wall of silence Information approved to our local quality music. Because there's more and he and Tommy with their incessant agitation war done in every club in the world have demonstrated. And now I'm here with this manifesto, a behemoth of 21 tracks combining all the imaginary sound of "beets bleeding." There are baroquisms classic between Rondo Veneziano and Giorgio Moroder ("Have Mercy On Us" with the next big thing Cécile), there are synths zarri and sizzling, and those beats iperpompati (in "It's Better to DJ On 2 Turntables" or " Warp 1.9 (feat. Steve Aoki) "), there are distortions that are so hard punk (in" Talkin 'In My Sleep (feat. Lisa Kekaula) "or the title track itself with guest Leather or part of The Locust), there is the legacy of rap electro Baambaata Afrika (as represented by the International Cool Kids in "Awesome", the Italian version of Marracash in "How The '), there are also "dance" in which electronic beats and melody melt overflows (in "Second Streets Have No Name (feat. Bow Beta) 'or' Little Stars (feat. Vicarious Bliss)"). There is all to show that after the Justice, willy-nilly, is "Romborama" with all the pros and cons of the case. Let's just say that the main obstacle to deal with a work like this is that it is extreme at all costs. An aura of heaviness hovers threateningly. It is difficult to get to the bottom, even if the pearls are in the process. It is difficult to accept him as an lp to listen to from beginning to end. But in general, all records of this type have shown this weakness, so far. By Justice, to Digitalism, Boys Noize until: I defy anyone to resist until the last minute of each of these discs. "Romborama" does not make a difference in this regard. This does not detract, however, its importance and conceptual music.

FLEX-5000A with RX2: total flexibility

The FLEX-5000A transceiver is designed with a hardware architecture is very flexible. In addition to the many connections to different types of accessories (see card FLEX-5000A), it can be mounted inside your cabinet for a second receiver (RX2), in all respects equal to the main receiver (RX1) completely managed by PowerSDR in simultaneous RX1.

RX2 can be configured at any time in order to use one of the three antennas available on the FLEX-5000A or an antenna dedicated to it (on exclusive input connector). RX2 are possible with different "scenarios to be" very interesting
  • monitoring of a band other than the RX1
  • listening mode "Diversity" (requires special PowerSDR)
  • listening on the other side even though RTX is Transmission (with antennas)
  • analysis of CW signals in a specific band (with CW Skimmer)
On this last mode I understand the importance of RX2 and the incredible flexibility, not found on any other transceiver amateur, the FLEX-5000A with RX2.


picture above you can see a very complex configuration PowerSDR, similar to that presented in the previous post but with the introduction of RX2 (note panadapter of PowerSDR divided in half: on RX1 - RX2 below).

In practice, we have this situation:
  • TX RX1 & LSB on 40M (with dipole)
  • RX2 on 20M CW (VAC enabled to 96Khz)
  • CW Skimmer in analysis
  • Logger32 with RX2 enabled on DXcluster CW Skimmer
  • Tmate for tuning "manual" RX1 or RX2 choice.
when configured as above is possible, for example, make a QSO on 40M and simultaneously monitor the traffic you receive on CW in the range of 20M (or whatever) and in the case of a spot of interest to us, by clicking on Logger32, the RTX (RX1 & TX) automatically tunes to the frequency and mode of the SPOT to make immediate call to the station reported. As you can see by CW Skimmer RX2 CAT controls, without being confused with RX1, as CW Skimmer provides the opportunity to select their own (only PowerSDR) which of the two handsets to use and control. The "audio link" between RX2 and CW Skimmer is also made using Virtual Audio Cable (VAC), specifying in PowerSDR to send the signal of RX2 only. The link management CAT is always entrusted to VSPE.

E 'should also be noted that the use of RX2 is well integrated into the chain of forwarding, that can be operational immediately place in either band (RX1 and RX2), with the right antenna and the
other specific parameters of the band, with just one clik of a mouse!

Bethesdia Fountian Angel, Replica For Sale

Vcom + VAC for seamless integration of SDR


Hello,

to completion of the previous post here is another example of what can be done by connecting through various programs with a SDR virtual serial ports and, to introduce the subject, even with VAC: Virtual Audio Cable.

Above image showing running a real operating conditions, high performance and fully synchronized in all its components:
  • PowerSDR FLEX-5000A transceiver on
  • program LOG station: Logger32
  • CW Skimmer
  • Tmate
Behind it all is that CW Skimmer, using the Virtual Audio Cable, receives a stream of 96Khz PowerSDR full of information that appear as CW signals, identifying CALL - Frequency and speed of transmission.

The transceiver is tuned in the range of 40M, set for release in the CW and is controlled by CAT CW Skimmer: just click one of the signals on the waterfall display of CW Skimmer to automatically tune the signal on PowerSDR/FLEX-5000.

not all here as CW Skimmer has a telnet server with which it can transfer information to another program. In this case Logger32 received this information and shows them as coming from a DX Cluster, and highlighting the data cross-checking them with those of LOG of our links.
Again, again via Vcom, Logger32 FLEX-5000 can tune the frequency of a station of our interest reported on the DX cluster window.

Logger32 also operates the CW Keyer, from which you can transmitted directly without button, connected to
PowerSDR/FLex-5000 with a virtual serial port dedicated to the Keyer. To finish the

sistuazione shall Tmate that can be used to fine tune the VFO or, as in the figure, tune the VFO B for the possible transmission SPLIT.

In short the connections CAT: CAT
  • PowerSDR/FLEX-5000 with attivosu COM7
  • CW Skimmer / Logger32 / Tmate on COM8 (splitter COM7)
  • PowerSDR/FLEX-5000 with keyer port on COM5
  • Keyer
  • of Logger32 on COM6 (couples with COM5)
PowerSDR CW Skimmer and connected via Virtual Audio Cable to 96Khz to send the contents of the Spectrum I & Q.

Thanks for reading, next to the post analysis of the Virtual Audio Cable

How To Hugg Cooking Spray

Serial Ports ( 232) virtual because they do and how to use them (Part II)

Hello,

resume the discussion on virtual serial ports, which are necessary for seamless integration of SDR with the various programs of traditional use in a station radio, focusing on a variety of software: Visrtual Serial Port Emulator (VSPE), available for free on the Eterlogic .

VSPE, unlike other software of this type, does not install a permanent serial port driver in the operating system (ie not on the list of devices the OS) but it creates the required devices when you need to be chosen by the user and configuration files that can be loaded at will. In the configuration file is to record all information of the various ports that we created, including the classic parameters of speed, parity, etc. etc.. It 'important that all devices, both hardware and software that we want to connect, use the same communication parameters.

Normally, when the configuration meets the needs of the user, the configuration file can be put into the autostart folder of Windows so you do not have to do any manual operation.

This is the "panel" of VSPE, one of our example, which shows the serial ports Virtual active in the system and used in a configuration that SDR will be seen below.


VSPE allows different types of serial ports, including some very special type of UDP to be used in remote connections. What you see in the panel above are of 2 types: COM 7
  • type "CONNECTOR"
  • COM 8 type "SPLITTER"
The COM 7, type CONNECTOR, is a virtual port that is responsible to create a primary connection, a port to be dedicated to software to communicate with other software, such as a CAT SDR radio.

The COM 8, type splitter is a very special door and exclusive VSPE not present in any other program of its kind: it allows multiple programs to simultaneously share a port type connectors. It 'a kind of brings very useful as it allows various programs to share a radio and CAT, the information in transit, are available to each of them. Through a door
SPLITTER we can, for example, controlling a SDR with a logging program and at the same time, the SDR can be controlled by yet another program.

image above is visible then another port: COM 1 \u0026lt;=> COM redirector type 8, which has the task to redirect the serial port COM 8 on a "real" (COM1) to allow external devices that use software to connect to virtual ports. This type of feature is unique to VSPE and allows, as in the example below, to link up via the CAT EXPERT 1K-FA linear amplifier.

VSPE described configuration is actually used in the SDR configuration shown here:


The image configuration "CONTEST" which includes:
  • FLEX-5000 can operate with PowerSDR, CAT enabled COM-7
  • Software N1MM on COM 8
  • Tmate on COM 8
  • EXPERT 1K-FA COM-1 (redirected COM-8). The remote management software amplifier is connected to the same port with another "real" COM 2 on your PC.
In practice, all devices being connected, are perfectly synchronized in the manner and frequency (regardless of who carries out a variation or PowerSDR Tmate or N1MM), then you can tune in on the SDR panadapter Click on a SPOT DX CLUSTER, turn the knob to change frequency Tmate / how all connected devices.

amplifier, because of its great features, it is always ready and tuned to the frequency of use in an automatic and instantaneous.

VSPE The possibilities of use are varied, allowing a complete management of virtual serial ports of any kind and for any needs related to the Protocol CAT sommutazione automatic antenna rotor commands, synchronization of multiple devices, etc. etc.

We hope this article may be proved helpful in understanding the "why" and "how" virtual serial ports are needed in a modern amateur radio station based on Software Defined Radio.

Yeast Infection And Bleeding

Serial Ports (RS232) virtual because they do and how to use them (first part)

Hello,

start this series of "notes" or "advice" with a subject absolutely necessary for a full use of our Software Defined Radio inserted into a modern amateur radio station. Certainly this

argument is not a stranger, for many years, radio & PC integration is well established in many articles, blogs, etc. etc.. We

a brief review, however.

When using "everyday" of our station is a normal thing to have our traditional radio connected to PC via RS232 port to the "physical" connection between the radio and various software to manage our station, for example:

- the program LOG
- DX CLUSTER program (often already included in the LOG)
- the program to make connections in the digital modes
- the program for the contest

All of these programs, even if they could work on their own, if given the opportunity to "talk" with our radio, to automate the reading of some parameters such as frequency, mode of issue, etc. etc..

Radio and such software "speak" by means of a language, communication protocol, which is normally available via a RS232 cable: one end of the cable is connected to the serial port of your PC, the other end to the " CAT "on the radio. Well, once set to program the serial port to use and set up the parameters of communication, radio and computers are able to exchange the information necessary to perform the operations required.

And with our Software Defined Radio, which is itself software, to make it work with CAT, where I connect the serial cable?

Good question ...... the answer is easier than you think, that is:

- the type PowerSDR or PERSEUS SDR is a radio in every respect
- as (almost) all radio CAT has a trade protocol
- like all the CAT requires a serial port .... but virtual!

virtual serial ports (Vcom) are true RS232 devices that, once installed on the OS, are seen by the software as a standard serial port "real."

Just then, once in the system we have installed the software for the creation / management of Vcom, directing programs that require it to one or more of these virtual serial ports.

Among the software available to create and manage virtual serial ports, some in the public domain and some for sale, the most famous are:

- N8VB Virtual Com Ports
- com0com
- VSPE (Virtual Serial Port Emulator)
- Eltima

The first 3 are free, the last is for the professional market and is free of charge.

We foicalizzeremo on explaining the use of VSPE that, in our opinion, is the most powerful and simple (once you understand the mechanism) to use.

prossino On a post, then, everything about VSPE and as a SDR interface and other software.

Why My Sensor Light Stays On

Tune with WoodBoxRadio

In conjunction with the commissioning of the new site on LNE www.woodboxradio.com we decided to create this blog too, with the idea of \u200b\u200busing it as our "laboratory diary."

The idea is to provide readers information that often help to solve small "bottlenecks" in the use of the Software Defined Radio.

For example:

  • the use of virtual serial ports
  • the use of virtual sound card (VAC)
  • interfacing with other CAT programs
  • how to optimize the system for digital modes
  • use in CONTEST
  • etc etc etc
so soon and thanks for visiting
