Hello, Facundo,
?
I use an IC-7300 for HF Winlink. The Icom driver software puts two com ports on the computer. Only one works with RMS Express email.
?
For the 2m Winlink gateway I am using a Rigblaster Nomic sound card and an Icom 2m mobile radio. The Rigblaster software puts one com port on the computer. I tried VOX and it did not work, although VOX works for other sound cards like Signalink. The installed com port worked fine with either Soundmodem or VARA FM, but not both together.? I installed com-port-splitter software as mentioned in this topic and it produced two com ports which allow both VARA FM and Soundmodem to work and respond to incoming email requests.
?
Scott does not recommend running both together because of potential conflicts if there is incoming RF signals at the same time. See "RMS Packet Dual-Mode (Packet and VARA FM Setup" on Winlink.org.
?
Although both work for me on a test gateway, I will probably only run with one, depending upon the interest of our club.
