RMS RT9K — antenna replacement, new frequencies & transceiver upgrade

Submitted by RT9K on Sun, 2026-06-07 14:51

The previous antenna has been replaced with a ZS6BKW multiband dipole, a well-proven design that provides efficient coverage across the HF bands from 40 to 10 meters. This antenna offers significantly improved radiation efficiency and broader frequency coverage compared to the previous setup.

As a result of the antenna change, the receiving frequencies at RT9K have been updated. Users who have previously connected to this gateway are advised to refresh the station's channel list in their Winlink Express software to ensure they are connecting on the correct frequencies.

Amateur Radio Safety Foundation, Inc.

Winlink Global Radio Email®️ is an all-volunteer project of the Amateur Radio Safety Foundation, Inc. (ARSFI), a non-profit public benefit corporation with no beneficial owners.

Please give to ARSFI if you use Winlink radio email or correspond regularly with someone who does. By donating $25 each year you will do your part to improve this system and keep it running. Donations are tax-deductible by most US federal taxpayers. This is the best way to say "thank you" to Winlink volunteers! You can also purchase a registration key for your Winlink Express software. That's different than a donation! And is another way to contribute.

WANTED:

Software and Hardware Developers
The Winlink Development Team is looking for talented software and hardware developers who have expertise in Digital Signal Processing, embedded firmware, RTOS, VB, C#, C, C++, dot-Net Core, Python, JavaScript, OSX, iOS, Android, Open-Source Project Management, GitHub and AWS experience. We need PCB Designer, fabricator and supply chain expertise. We need developers who can move our programs to new platforms and environments, keep pace with internet mail and security standards, and to help innovate for the future. If you have volunteer time, are willing to help, work well with others and would like to join an accomplished team, please contact Mooneer Salem, K6AQ, and Tom Lafleur, KA6IQA.

Outstanding Volunteers

The Winlink system is run entirely by volunteers. Those called Gateway Station Sysops, who support and run over a thousand stations around the world, are special. They are essential for providing the radio network that allows us to use Winlink radio email. Without them, there is no Winlink. If you use Winlink radio email, make sure to thank your sysops by sending them an email to their RMSCALLSIGN-at-winlink.org address.You can find their contact information by mousing over their call sign on the RMS List tab here.

Apart from the Gateway Station Sysops and Development Team, there are other volunteers that run e-mail groups and tutorials, manage user accounts, register software, update the network's assets and catalogs, test and debug products, provide training, and independently write software. They all work together to keep the Winlink system running smoothly. Thank you to all the hardworking volunteers, authors and developers who contribute to the Winlink system. Some are exceptional and deserve special praise:
