UZ7HO version 0.96b and above has changed the Settings/Modem Mode from “VHF AX.25 1200bd” to “AFSK AX.25 1200bd”.ĪGW Express by W2YG is no longer supported due to changes in Winlink Express (formerly RMS Express) that now allows the use of the UZ7HO Sound Modem. This also greatly improves accuracy of the reported data as the data isn’t touched once it leaves the aid station / no transposition errors and is reported to the public via social media much more quickly.For soundcard packet the signal bar on the waterfall should be centered at 1700 At the event I’m most familiar with ( ) multiplying 370 runners times the number of reporting aid stations meant that nearly 4,000 pieces of data that were being reported via voice are now reported via WinLink. Using the template features within WinLink > Message > Template > Standard Template > Race Tracker.txt, check point information is being sent via WinLink thereby clearing the voice channels at these events of non-critical traffic. “Beyond person-to-person e-mail (and ARES/Emcomm/FEMA reporting), WL2K is also being adopted by some endurance running and equestrian events as a means of sending runner / horse progress reports from remote aid stations.

TNC setup – Session BW 2000, Drive 70-90.

Filters and radio settings as in digital modes, bandwidth can be set to 3.6k or narrower if needed.

Change busy detector to 0 if you have trouble with false busy indications or try 0-5.

No need for CW/ID at the end of transmission.

Mode USB-D1, 10-100 watts power output and ALC when transmitting no more than 1/3 of the ALC scale (red bar on ALC scale). Receive filter bandwidth is set to 3.6k, but I have found narrowing it to 2k or even 600Hz may be helpful. Have a look at my 73 screen captures page if you need to see the menu settings. I use the same settings as I use with other modes like PSK31 and FT8. In the video below I am using the Icom 7610, but this will apply to the Icom 7300 as well as other radios. The bandwidth can be forced by server, forced by client or negotiated by the server and client.Ĭhannel adaptability: The protocol is intended to be able to operate over a wide range of data rate and robustness levels by automatically adapting to propagation and channel conditions, seeking the best modulation and bandwidth to maximize net error-free throughput. About ARDOPĪudio bandwidth options: The initial ARDOP protocol is intended to operate in one of four audio bandwidths, 200 Hz, 500 Hz, 1000 Hz, and 2000 Hz. There is another protocol called VEGA Winlink, more on that in another post. It is like Winmor in that it is included in Winlink Express and it is free.

Most hams are familar with Winmor Winlink.ĪRDOP is my favorite so far. I am exploring two Winlink protocols, Winmor and ARDOP.
