Don't feel obligated to enter a detailed message if it's difficult; the important part is the Subject line!

The VDEN website (https://vden.org) includes information about the Central Virginia BBSes, how to send personal mail and bulletins, and methods for connecting over RF (Packet / Vara via Terminal / Winlink / Outpost).

Bulletins created on the N4VEM BBS will be forwarded over Vara FM to the KN4LQN BBS, which will then forward over Vara HF to the N3MEL BBS and the wider regional packet network.

Reach out if you have any questions!

Connecting via Vara Terminal using Vara FM / HF

Vara is a newer mode that is robust and fast, using scaling speeds with OFDM modulation.

Vara FM can use WIDE audio bandwidth signals for faster speeds, depending on hardware setup, and includes digipeating functionality similar to AX.25 Packet.

Vara offers an optional $69 license for the use of faster speeds and FM digipeating.

The Vara Terminal application uses either TNC to connect to a remote BBS to give keyboard terminal access.
