Winlink hub mode working-one of the solutions for emcom working.

Windlink hub working between 3B8FO and 3B8DU implemented successfully.
Mail  sent to FO by DU was successfully retrieved by FO using vara ,with DU RMS station working in hub mode with no internet connection.

This means that even when  there is no internet connections mails and files can be sent and retrieved via radio through a winlink station working in hub mode.

One of the HF solutions for emcom.

The champion digital file transfer mode for HF emcom --VARA of winlink

3B8FO conducted some very successful digital mode tests using vara of winlink  this morning on the following bands 15,20,30,40m.

Tests were carried out with winlink Radio mail server (RMS) of 3B8DU.

Power used was 10W and antenna was NVIS inverted -L  160m multiband with MFJ auto-ATU.

Software used is winklink express which can be downloaded from  https://www.winlink.org/WinlinkExpress.

Winlink express is a free software used for hf mail and P2P standard emcom file transfer .To prevent the nagging registration reminder you better get a registration key for 24$ .

For the time being we have two sysopt RMS 3B8 land station ,3B8DU and 3B8FO.
