Thanks for your answer,
apparently I can not activate the "Send File" button because it is greyed out, not active.
I usually use image software such as YONIQ (EA1IMW) or MMSSTV (JE3HHT), EASYPAL (Vk4AES), SIMPLE IMAGE CONTROLLER (JQ1HDR), KG-STV (JJ0OBZ) and finally EZ-PIX (W3WVG) that is compatible withe EASYSIMPLE and VARIFRONT.
This is the first time that I can not start in image, maybe it is necessary to have the license,
I do not know because I do not find any information or special help for this new integration, maybe it is too early, we must wait.
Thank you Jo 73 have a good day
