The RSGB has the call sign GB19YOTA and we’re looking for radio clubs, schools, Scout and Guides groups, Cadet groups, and individuals to activate the call sign or host a station.

This makes it possible to send, receive and show pictures by the IC-9700 itself.
 
Pictures stored on your smartphone or other device can be sent through the IC-9700. Using the ST-4001A/W picture utility software, you can select a picture to be sent, and then transfer it to the IC-9700 through a LAN. The IC-9700 does the rest. Image data is transmitted during voice communication, or transmitted in the DV fast data mode, by pressing a button on the display, too. The IC-9700 can also show the received picture on its LCD display.

Japan introduced its entry level Class 4 licence

QRZ Now - Fri, 10/11/2019 - 06:29

Japan introduced its entry level Class 4 licence in the the late 1950’s, it would prove to be the world’s most successful category of amateur radio licence, taken by over 3 million people

The work required to get a Class 4 licence is less than that needed for UK Foundation. It takes about 10 hours study and unlike the UK Foundation there are no Practical Assessments just a short multiple choice test at the end of the course. It seems pass rates of 97% or higher are commonplace.

A Class 4 licence permits the following:
• 1 watt EIRP on 135 and 472 kHz
• 10 watts output on 1.9, 3.5, 7, 21, 24, 28 MHz bands
• 20 watts output on 50, 144 and 430 MHz bands
• Varying power levels between 10 watts and 0.1 watts on ALL amateur bands between 1240 MHz and 250 GHz.

It is notable that Japan gives their Entry Level Licence class full access to all the Microwave and Millimetric bands.

100W input power

Output power 1200W (SSB/CW)

                       800W for digital mode with 42V


Water cooling

Two levels of blowing. Running the second level at a copper radiator temperature is more than 50 degrees Celsius. Stop transmission for copper radiator temperature is more than 80 degrees Celsius.

Supply voltage 53V 35A
Voltage  13.8V  2A
SWR protection
Current Protection
Protection in power output
Protection against spontaneous or incorrect switching LPF.

Power amplifier protection device:

Protection from exceeding the output power of 1200 watts.
Protection against exceeding the maximum drain current of the LDMOS transistor.
Protection against overheating – two thresholds of operation:
when the copper radiator is heated more than + 50С – the accelerated mode of the fan operation is activated to increase the heat removal.
when the copper radiator is heated above + 80 ° C, the protection system trips, breaking the PTT circuit. Transmission is not possible.

Hawaii ARES Leverages Contest Station and Winlink for 2019 Simulated Emergency Test

QRZ Now - Wed, 10/09/2019 - 12:41

ARES volunteers in Hawaii took the opportunity of the 2019 Simulated Emergency Test (SET) on October 6 (UTC) to test Winlink radio messaging to the US mainland, using the KH6YY (KH6J) contest station on O’ahu. One of the premier contest stations in the middle of the Pacific Ocean, KH6YY offers a commanding propagation path over an expanse of saltwater.

“You have to start with digital modes somewhere,” ARRL Pacific Section Manager Joe Speroni, AH0A, said, conceding, “We have a long way to go.” A group of radio amateurs has developed a robust Winlink system in the Hawaiian Islands to help support communication in a natural disaster. The Amateur Radio email system is well known for its role in emergency and disaster relief communications, providing the ability for users to exchange email with attachments, photos, position reporting, weather, and information bulletins. Winlink was extensively used in the aftermath of high-impact hurricanes in the Caribbean, as well as following an earthquake in Mexico.

Hawaii boasts the most isolated population center in the world — 2,390 miles from California and 3,850 miles from Japan. Pretty much everything is DX.

KH6YY sports eight antennas, most on 90-foot towers, and nine operator positions. For the SET, the station was configured to receive traffic on 7,100 kHz (dial frequency) in PACTOR, WINMOR, ARDOP, and VARA modes. The four-element 40-meter beam was aimed at Hilo. Simulating an internet outage, the setup was used to pass received traffic to a second 20-meter gateway on 14,100.5 kHz and forwarded to a mainland gateway with internet access. 

 

Incoming message traffic on 40 meters would be automatically forwarded to the mainland on 20 meters. Most of the traffic went to gateways in Mexico and Texas for forwarding to the internet. One user reported receiving email confirmation that a message was received within minutes. — Thanks to Stacy Holbrook, KH6OWL

Tokelau Islands ZK3A DXpedition Ceases Operation Early

QRZ Now - Wed, 10/09/2019 - 08:57

Due to the illness of a ZK3A Tokelau Islands DXpedition team member, the operation has shut down a couple of days ahead of schedule.

“ALL TEAM MEMBERS ARE FINE!” said an announcement on the ZK3A website. “A person on the island is ill. So, they have sent the boat there early to get this person medical help. The team has ceased operations and [is] packing up all equipment to get on that boat, because there will not be another boat for ten days.” The announcement did not identify the ailing team member.

As of October 8, ZK3A had logged approximately 50,000 contacts in 7 days of operation on CW, SSB, RTTY, FT8, and EME, as well as 10 contacts on slow-scan TV. The DXpedition had been set to conclude on October 11. Hrane Milosevic, YT1AD, is the ZK3A team leader.
