Broadcasters Intruding on Exclusive Amateur Radio Frequencies

QRZ Now - Thu, 12/13/2018 - 3:51pm

The International Amateur Radio Union Region 1 (IARU-R1) Monitoring System (IARUMS) reports that Radio Hargeisa in Somaliland has returned to 7,120 kHz after a break of several weeks, while Radio Eritrea has been reported on 7,140 and 7,180 kHz. Radio Sudan has been transmitting on 7,205 kHz with excessive splatter, IARUMS said. German telecommunications authorities have filed official complaints.

IARUMS has also reported digital signals attributed to the Israeli Navy on 7,107 and 7,150 kHz. In addition, a Russian military F1B signal was observed in mid-November on 7,179 kHz. A Russian over-the-horizon radar has returned to 20 meters on 14,335 – 14,348 kHz. It was monitored on November 22. Earlier this fall, IARUMS reported digital signals from the Polish military daily on 7,001.8 kHz where Amateur Radio has a worldwide primary allocation. Telecommunications officials in Germany filed a complaint.

IARUMS has received reports of short “beeps” exactly 1 second apart, as well as frequency hopping between 10,108 and 10,115 kHz and 18,834 and 18,899 kHz. The signals are believed to emanate from a site near Chicago associated with an FCC-licensed Experimental operation involved with low-latency exchange trading on HF (see “Experiments Look to Leverage Low-Latency HF to Shave Microseconds off Trade Times”). Although Amateur Radio is secondary on 30 and 17 meters, Experimental licenses may not interfere with Amateur Radio operations.

Digi Mode Ham Radio Hat for Raspberry Pi

QRZ Now - Thu, 12/13/2018 - 1:12pm

“Hello Operators in the first video with the DRAWS HAT for the Raspberry Pi, I speculated about the impact this new hardware would have on the ham radio digital mode community.

Well now I have the DRAWS hat in my hands, so we can take a close-up look at what’s in the package, and what the hardware is all about.I’m running a hybrid station. That is to say, I use an Android tablet to interact with a headless Raspberry Pi. My Raspberry Pi is running JS8Call, FLDigi, WinLink, and WSJT-X. my Raspberry Pi Hardware is the 3B+ NW Digital Radio calls it a Digital Radio Amateur WorkStation.

I can’t tell you how stoked I am to finally have this product in my hands. In short, the DRAWS HAT makes integrating the Raspberry Pi with a HF radio easier and less expensive than ever before. Fewer cables, no audio interfaces, no cable mess, and a clean installation.Why we should care about DRAWSTo be honest with you, when I first ran into this device, I thought to myself, wow someone has been watching my videos, solving the problem of integrating the Raspberry Pi, with all the components we need for digital communications. DRAWS is a Raspberry Pi HAT.

This is a purely hardware solution combining several components for digital amateur radio, into a single integrated solution.”

New Regions Brighten the Sun’s Face: Solar Storm Forecast 12-12-2018

QRZ Now - Wed, 12/12/2018 - 5:03pm

“The fast solar wind we have been enjoying over the past week from an extended coronal hole is finally beginning to wane. We will likely remain at unsettled conditions over the next few days and return to quieter conditions by the end of the week. We also have 3 new bright active regions on the Earth facing Sun that are boosting solar flux for amateur and shortwave radio operators and emergency responders. This means radio propagation is back to marginal levels on Earth’s day side and will likely remain that way over the next week. See the details of these bright regions, catch up on aurora photos from the recent solar storms, and see what else our Sun has in store this week!”

TS-890S – Kenwood

QRZ Now - Tue, 12/11/2018 - 4:54pm
The most rewarding results often take place when faced with the harshest and most challenging conditions.
There are enthusiasts who know this all too well because of their love of DX. KENWOOD has the answer.
Achieve results through certainty and not circumstance. Delivered through impeccable receiver and audio performance.
This is our offering to you. Top in its class with three dynamic ranges.
Alive and well, the non-tiring KENWOOD tone keeps you listening. Receive performance on a whole other level from narrow bandwidth roofing filters that only full down conversion can provide

The TS-890S uses 8.248MHz 1st IF frequency down conversion for its receive signal system in order to continue the adjacent interference signal exclusion legacy refined in the TS-990S. This means you can use narrow bandwidth crystal filters with passband widths of 500Hz or 270Hz (optional YG-82CN-1) as roofing filters to achieve strong exclusion of unnecessary adjacent signals. The 1st mixer is the H-mode mixer also carried by the TS-990S. Conversion characteristics have been improved with fine-tuning of input/output matching as well the device used.

High-speed scanning with independent band scope receiver

The configuration of the band scope receiver has changed from the superheterodyne system used in the TS-990S to 1st IF sampling using an A/D converter (14bit/39MHz), and FPGA digital down conversion. This means a change in scanning method from step FFT to FFT, achieving highspeed updates to the display irrespective of span settings.

Local oscillator realizes superior C/N

Interference signal exclusion is not determined by roofing filters and signal system devices alone. The TS-890S has taken the VCO division of the TS-990S and developed it further, combining a VCO device with high C/N in the gigahertz band and a reference oscillation circuit with superior adjacent C/N to deliver C/N characteristics unattainable in conventional units.

The speed and quality of KENWOOD’s renowned IF AGC control

A variety of functions are realized through 32-bit floating-point DSP technology inherited from the TS-990S, including modulation/demodulation in all modes, IF filter, IF-AGC, and removal of interfering signals. Popular for its non-tiring and great-quality audio, the IF-AGC has undergone a facelift with a combination of roofing filters and IF filters, and has been designed to enable optimal control under various noise circumstances.

Evolved power to perform with diverse displays and auto-scroll.
A transmitter with stable output, quietness and high speed. Operational capacity reinforced with displays and various features

The seven-inch TFT color LCD is the same size as that used in the TS-990S. In addition to basic information including frequency, mode, and S-meter, the band scope and audio scope are also displayed. The TS-890S also displays further improvements in visibility and operability in tough usage scenarios such as competitions.

With the spectrum scope and waterfall screen display, the analogue meter is simultaneously displayed. The popular sub-scope display from the TS-990S has been incorporated as a filter-scope display

A band scope providing ease-of-ease

AUTO SCROLL MODE

In addition to conventional CENTER MODE and FIXED MODE, the unit comes equipped with an AUTO SCROLL MODE. While in FIXED MODE, if the receive frequency goes over the scope edge, then autoscroll will engage for half a screen width. Furthermore, with the EXPAND function turned on, the screen to be displayed next can be drawn in advance*. Also, with the SHIFT function, the receive marker can be set in the desired position on the vertical grid, which is convenient when displaying a non-receive frequency as the center display, such as for pileups during splits.

  • * Effective in spans under 200kHz. Image becomes slightly coarse when expanded.

Auto-scroll operation (span 10 kHz, EXPAND ON)
On the current screen (screen 2), if the frequency is changed to go over the top end of screen 2, it will automatically change to screen 3, and if it goes over the bottom end of screen 2, it will automatically change to screen 1. Waterfall screen creation normally commences after switching screens, but with the EXPAND function turned to ON, the display switches to the finished screen.

 CENTER MODE

When changing the receive frequency in CENTER MODE, there are many units that display a bright line that flows obliquely over the waterfall, but with the TS-890S, the bright line remains straight and enables tuning operation*. Switching to the follow display is also possible via the menu.

  • * During straight display, the waterfall bright line temporarily stops and undergoes parallel displacement. Image becomes slightly coarse when expanded.

● FIXED MODE

FIXED MODE allows you to switch between three kinds of display ranges with a single touch of the panel screen. The initial value is preset based on the band plan, but this can be easily adjusted to a desired scope.

Improved reference level operability ease-of-use

The TS-890S has improved operability of the reference level focusing on the visibility of the waterfall.

● Through optimization of each span, readjustment is mostly unnecessary when switching between them.*
● Settings are enabled for each band, and readjustment is also unnecessary for the PRE AMP ON and PRE AMP OFF bands.

  • * Spectrum scope waveform height changes during span switching.
Filter scope display

The popular sub-scope from the TS-990S is carried as a filter scope display. You can confirm receive filter selection status, roofing filter bandwidth, IF fi l ter passband information, receive for ex-audio spectrum, CW pitch frequency, and notch frequency all concentrated in one location.

Expanded touch operation scope

Basic operation of the TS-890S is through knobs and switches with a definite ‘clicking’ feel rather than touchscreen operation, but the below adjustment features and menu settings can now be changed via touch operation.

RX/TX equalizer level adjustment, meter type (analog white / analog black / bar meter) switching, FFT scope/X-Y scope switching on RTTY decode screen, FFT scope/vector scope switching on PSK decode screen, voice-audio file playback position change. Furthermore, with touchscreen tuning, in addition to the conventional CW tuning operation via longpush, a short push enables tuning using steps set via MULTI/CH, while on bands popular with operation in units of 1kHz, practical touch alignment is possible even in SSB.

Other display system features
  • ● Transmit digital meter enabling display of two kinds of transmit information even during analog meter display
  • ● Audio scope (spectrum scope, oscilloscope) able to be displayed simultaneously with reduced band scope
  • ● Band scope IF filter passband with display
  • ● Change of gradation for waterfall display
  • ● Frequency marker display function (Max. 50)
  • ● Transmit spectrum display (during CENTER MODE)
  • ● SWL display mode
Heavy-duty design delivers transmission performance able to withstand long hours of operation. Highly reliable 100W final-stage amplifier circuit.

The final-stage amplifier device is a Mitsubishi-made MOSFET RD100HHF1(Pch 176.5W) operating in push-pull. A MOSFET RD16HHF1 has been used for the drive amp, and a MOSFET RD06HHF1 for the pre-drive amp. Inter-stage matching and fine-tuning delivers superior transmit IMD even for a 13.8V final circuit, enabling operation with a clean and low-distortion signal.

Heavy-duty design with improved quietness

The unit employs a twin cooling fan system that uses a pair of 80 x 80 mm fans. Using two fans provides sufficient air flow at low rpm, making for superior quietness. The quietness level for the fans when operating has been improved by more than 5dB compared to our conventional models. Furthermore, the use of an aluminum die-cast chassis combined with a large heat sink makes for a heavy-duty design sufficiently capable of withstanding the tough conditions typical of contests or long hours of hard operation.

Built-in high-speed automatic antenna tuner enabling high-speed operation

The antenna tuner is a preset type also operable during receive and covering amateur bands from 1.8MHz~50MHz. High-speed operation and the proven relay method enable rapid QSY through instantaneous band changing. The menu can be used to set an ON/OFF memory for the antenna tuner for each band

Free settings enabled through linear amp control settings menu

A variety of linear amp connections have been taken into account, including self-made ones, and independent settings for various kinds of control at HF/50MHz bands are possible. Possible settings include: linear amp ON/OFF, transmission control (H active, L active), transmission delay ON/OFF, transmission delay time (CW/FSK/PSK) and (SSB/AM/FM), internal relay control, and external ALC threshold voltage adjustment.

Equipped with a TCXO (temperature compensated cr ystal oscillator) requiring no warm-up as standard, high stability of ±0.1ppm has been obtained in a wide temperature range covering from 32ºF~122ºF. External standard signal (10MHz) input is also possible.

Jordan’s First CubeSat, JY1Sat, is Designated as JO-97

QRZ Now - Tue, 12/11/2018 - 12:55pm

JY1Sat, launched on December 3 from Vandenberg Air Force Base in California as part of the SpaceX SSO-A: SmallSat Express launch, has been designated as Jordan OSCAR 97 (JO-97). The 1U CubeSat is a project of the Crown Prince Foundation of Jordan. Telemetry has been received and decoded around the world since the launch.

The spacecraft’s name recalls the Amateur Radio call sign of Jordan’s late King Hussein, JY1. JO-97 carries a 435/145 MHz SSB/CW inverting Amateur Radio transponder and a Slow-Scan Digital Video (SSDV) system to transmit stored images.

The telemetry downlink is on 145.840 MHz, the transponder downlink passband is 145.855 – 145.875 MHz, with an inverting uplink on 435.100 – 435.120 MHz. — Thanks to AMSAT

FT8 Enthusiasts Urged to Upgrade Now

QRZ Now - Tue, 12/11/2018 - 7:45am
WSJT-X 2.0 Full Release Now Available

The WSJT-X 2.0 software suite has been released, and developer Joe Taylor, K1JT, is urging FT8 and MSK144 users to upgrade to what will become the new standard, because the FT8 and MSK144 protocols have been enhanced in a way that is notbackward compatible with older versions of the program. That includes any version 1.9 releases.

“The new protocols become the worldwide standards starting on December 10, 2018, and all users should upgrade to WSJT-X 2.0 by January 1, 2019,” Taylor said on the WSJT-X home page. “After that date, only the new FT8 and MSK144 should be used on the air.”

Users are encouraged to read the new Quick Start Guide for WSJT-X. Gary Hinson, ZL2IFB, has released an FT8 Operating Guide.
