The post Dayton Hamvention Review – Ham Nation 403 appeared first on QRZ NOW - Amateur Radio News.

The RSGB’s Propagation Studies Committee (PSC) has released a new propagation tool for amateurs, based on the ITU’s ITURHFPROP program. The tool is the work of programmer and PSC member James Watson, HZ1JW.

The new tool gives you hour-by-hour monthly median propagation predictions from a location you specify to one of 28 locations around the world. Predictions are performed between the user’s position, expressed as a Maidenhead Locator (or the default value of IO92 if not specified). In some cases, performance for both long and short paths is evaluated.

The results are presented in tables, with colours used to represent the Basic Circuit Reliability (BCR), and numeric values to indicate the predicted median receive power (expressed in S Levels). As well as specifying your mode (SSB, CW, FT8 and others), you can also choose from a wide range of antenna types at both ends of the path. A tool to select your noise level is also included.

The tool also loads the results two at a time so that you don’t get an awkward 20+ second delay while the computations are completed. The details you input are cached, so that you should not need to change them the next time you use the program. Users also have the ability to print out the month’s predictions as a PDF file.

The tool can be found here.

Rediscover HF Again!

Building on the field-proven Airspy HF+ architecture, we designed the Most Refined HF/VHF SDR with world class performance in the smallest form factor.

The Airspy HF+ Discovery sets a new standard in terms of reception performance with extra pre-selectors for all the supported bands and a New DSP Core to optimize the gain distribution and the filtering parameters in real-time and dig deeper in the noise.

The signal path includes very high dynamic range data converters along with high performance passive mixers with an excellent Polyphase Harmonic Rejection structure. The included band-tracking pre-selectors eliminate unwanted interference and preserve the dynamic range of the receiver. With its world class strong signal handling capability and incredibly Low Noise, the HF+ Discovery is the ideal companion for All your High Performance Receive Scenarios.

Both the architecture and level of integration achieved in this design allow us to bring top performance reception at a very affordable price.
All the major SDR software is supported. Check the download page.

Ready to discover all these signals hiding in your spectrum?

Unrivalled Noise Reduction Processing

We spent a lot of time understanding RF noise, its structure, and how it interacts with legitimate signals. Today, we have one of the most flexible and acoustically pleasant noise reduction algorithms of the market. The applications range from high-fidelity hiss removal for Broadcast FM signals, to unburying weak SSB signals from the noise floor. Our algorithm doesn’t kill the highs to give you a false impression of loudness, yet it doesn’t have the typical high tone artifacts that plague popular noise reduction algorithms like LMS and Spectral Subtraction.
Here’s a very weak SSB signal in the 40m band, with and without our Digital Noise Reduction

Audio signal without processing:

Audio signal with our Digital Noise Reduction processing:

State of the Art SDR streaming technology!

We concentrated state of the art DSP and networking techniques into our SpyServer software to allow multiple users to stream high quality IQ data from the same receiver at the same time. No compromises in the quality were made like it is usually done in Web SDR interfaces. You get actual IQ data you can process with your plugins and extract the last bit of information out of it.
The server software is highly scalable and can run on computers as small as the $7 Orange Pi Zero to top end 64bit servers with multiple cores/cpus, including the popular Raspberry Pi series.

(adsbygoogle = window.adsbygoogle || []).push({}); HF Tuner

Airspy HF+ Discovery achieves excellent HF performance by means of a low-loss preselection filter, high linearity LNA, high linearity tunable RF filter, a polyphase harmonic rejection (HR) mixer that rejects up to the 21st harmonic and multi-stage analog and digital IF filtering.
The 6 dB-stepped AGC gain is fully controlled by the software running in the DSP which optimizes the gain distribution in real time for optimal sensitivity and linearity. Harmonic rejection is a key issue in wide band HF receivers because of the large input signal bandwidth of the input signal. The output of the IF-filter is then digitalized by a high dynamic range sigma delta IF ADC for further signal processing in the digital domain.

VHF Tuners

Excellent FM performance is also achieved by using optimized signal paths composed of band filters, high linearity LNAs with a stepped AGC, a polyphase harmonic rejection mixer and IF filters optimized for the FM broadcast bands.
The amplifier gain is switchable in 3 dB-steps and fully controlled by the AGC running in the DSP. The RF signal is converted to baseband by a high linearity passive mixer with a polyphase harmonic rejection structure. The low-IF signal is then converted into the digital domain by the same IF ADC used in the HF chain.
Extended VHF coverage is assured by a second Band-III tuner up to 260 MHz, but with reduced performance.

IF Sampling

The IF analog to digital converter (ADC) is a 4th order multi-bit noise shaping topology; it features very high dynamic range and linearity. The IF-ADC sampling rate is determined by a control algorithm running in the embedded DSP. This advanced technique adjusts the sampling rate depending on the tuning frequency with the goal of avoiding the disturbances and spurs generated by the switching discrete-time sections of the IF-ADC.

Digital Down Converter

Once the IF signal is digitalized, the high sample rate I/Q stream is then frequency translated and processed with cascaded CIC and FIR decimation stages. After every stage, the sample rate is reduced and the resolution increased. The final signal at the output has 18bit resolution and an alias rejection performance of 108 dBc. The data is then scaled to 16bit and sent to the Micro-Controller for streaming over USB.

Architectural Advantages

The main advantages over techniques from the legacy super-heterodynes up to the now mainstream direct sampling is that the whole receiver chain is well protected against out of band blockers while still relaxing the RF filtering constraints, making it simple and cost effective.
The natural filtering of the sigma-delta ADC combined with the excellent linearity and sensitivity of the analog chain reaches an unprecedented level of performance and integration.

Use it over the network!

Connect as many SDR applications as needed to the HF+ Discovery, over the Internet or in your own local network with near zero latency thanks to the new SPY Server software.
This setup basically brings all the flexibility of Web based SDRs while still benefiting from the full power of desktop applications. The IQ data is processed in the server with state of the art DSP and only the required chunk of spectrum is sent over the network. What is sent is the actual IQ signal, not compressed audio. This means you can use all your favorite plugins to process the IF, eliminate noise and perform heavy lifting of the signals as you are used to do with locally connected SDR’s.
We have a tradition of building multi-tools, so we made sure the SPY Server runs on 32/64bit Windows and Linux on Intel and ARM processors without any compromises. Low cost Raspberry Pi 3 and Odroid boards are in the party.

The post Do Dipoles Have to be Straight? [ The Doctor is In Podcast ARRL ] appeared first on QRZ NOW - Amateur Radio News.

Ampleon has released the first of a family of RF power devices based upon its Advanced Rugged Technology (ART) derivative of the proven 9th generation high voltage LDMOS process technology. The process has been developed to enable the implementation of extremely rugged transistors with operating voltages of up to 65V. 

The first product to use the process, the ART2K0FE, is a 2KW transistor with a frequency response of 0 to 650MHz, offered in an air-cavity ceramic package. It is designed to withstand the harshest conditions often found in  industrial, scientific and medical applications, in roles including driving high-power CO2 lasers, plasma generators, and some MRI systems. The ART devices are suitable for use in these applications because they can handle very high voltage standing-wave ratio (VSWR) mismatches of 65:1 at 65V, which CO2 lasers and plasma generators can exhibit in operation. 

Devices built on the ART process have high impedances to make them easier to integrate into products during the development phase, and to ensure greater product consistency in mass production. The process also enables devices to be built that have greater efficiency than competing LDMOS offerings. This reduces the operating costs of end applications by wasting less of the input electrical energy as heat. It also allows the devices to have greater power density, which means they can be offered in smaller and lower-cost packages, which in turn reduces their board footprint and so cuts systemic costs.

The ART devices also have a high breakdown voltage, which helps ensure that they will work consistently and reliably throughout their intended lifespan. Ampleon is also guaranteeing that the devices will be available for 15 years, to enable product designers to plan for the long term.

The ART2K0FE in an air cavity ceramic package is now sampling with reference circuits available at different frequencies. Ampleon also offers a lower thermal resistance over-moulded plastic version, the ART2K0PE. Production for both variants is expected in the second half of 2019.

—————————————————————–
ADIF 3.1.0 was approved today:

ADIF 3.1.0 specifies that the representation for FT4 is an ADIF record is

<MODE:4>MFSK <SUBMODE:3>FT4

This is the representation used in the current version of DXKeeper (14.9.2) when exporting an ADIF record. When importing an ADIF record, DXKeeper interprets both

<MODE:4>MFSK <SUBMODE:3>FT4

and

<MODE:3>FT4

to mean “QSO mode is FT4”.

As the software sages say, “Be precise when exporting, but tolerant when importing”.

The score distributor automatically forwards any score data it receives from contest logging software to the following online scoreboards:

• Contest Online ScoreBoard (COSB by VA2WA,K2BB,K5ZD)
• Live Contest Score Server (by R4WW)

Almost all contest logging software supports the capability to periodically post a user’s current score data to an online scoreboard throughout a contest. By configuring your software to send score data to the Score Distributor, instead of directly to one of the online scoreboards, you ensure that your score is represented on all scoreboards, not just the one you choose to follow. Select the Instructions tab above to learn how to configure your logging software.

Background

Contesting has traditionally been a very lonely sport. You sit in your shack, make QSOs, and then find out how you did at the end. That requires a lot of self-motivation to keep going, particularly when conditions are poor. By watching an online scoreboard while operating, it gives an idea of how you’re doing compared to others.

You don’t have to be in contention for a top-ten score to benefit from watching a scoreboard during a contest. Contesters with very simple stations have been motivated by seeing how they’re doing against another club member or buddy with a similar station

______________________________________________________________________

ContestOnlineScore.com is establishing a special award program to encourage the use of scoreboards during international contests. We are currently announcing three plaques that will be available for participants in the CQ WPX CW Contest May 25-26, 2019:

–  Highest Online Scoreboard  (Single operator Low Power)

–  Highest Online Scoreboard  (Single operator High Power)

–  Highest Online Scoreboard  (Multi-operator)

Single operator includes assisted or non-assisted entries.

Multi-operator category includes M/S, M/2 and M/M entries.

There is one requirement for all contenders, They are required to actively contribute their scores to Contest Online Scoreboard sent directly or forwarded over Score Distribution Server during all periods of their contest activity.

The plaques winners will be awarded after official results are published by the contest organizers. Any disqualified entries will not be eligible.

We are looking for plaques sponsors. Your name will be on the plaque!

The post Contest Online ScoreBoard appeared first on QRZ NOW - Amateur Radio News.

The changes include:

Support for several additional radios including the Yaesu FTdx101D.

A fix for typing several F keys quickly.

Fixes and additions to the supported contests.

Improvements to the default F-key messages.

Several cosmetic changes.

Please read the release notes for additional changes and details.

*NOTE* The names of several radios have been changed slightly to agree with what the manufacturer uses. DXLog 2.4.1 will recognize the old names in configuration files. However if you uninstall 2.4.1 and reinstall an older version you may need to go to the Configure interfaces dialog and set the radio names.

And there is still a known problem with the FlexRadio WinKey interface.

As always, if you plan to use this version in a contest please download and test it beforehand.

Paul, K1XM for the DXLog.net Development Team

Note: As of Apr-11-2019 the support email reflector is moved from Mailman to groups.io 

News: This software is now free of charge, donated to the ham radio community by
Krassy K1LZ and a few other guys donating their time and effort.
