Outside the Amateur radio 19 in rack cabinet are two tuned VHF Cavies for use by the Winlink VE3PRV-10 RMS gateway on 145.030 MHz. The RMS gateway also operates as a VARA FM Digipeater VE3PRV-4. VARA FM (in registered versions) can support up to two (2) digipeater relays.
For example, from Ottawa, I can connect using my VE3SMF home station using VARA FM on 145.030 MHz and use the VE3PRV-4 digipeater on 145.030 MHz, to connect back to the VE3SMF-10 RMS gateway on 145.030 MHz to send Winlink traffic into the Winlink CMS.
