Hall of fame
VarAC defaults to 500Hz, but when someone runs 2300, can we get it to decode both 500 and 2300?
I'm looking at it from the perspective of the coming file transfer feature... and use on other than hf.
Since we are using VARA... will 2750 be supported?
ok, I've just seen some wide bw stuff while on 500. Just used to things like FreeDV where you choose a mode, but it will decode all the modes, so you can hear a CQ regardless of mode.
the VARA-HF modem can be configured on either 2300 or 500. with one exception - if you are on 2300, you can still ask the modem to accept connections in 500Hz (see attached screenshot). but if you try to connect someone else while you are on 2300 and he is on 500, that won't work.
This is not a VarAC limit. Its the modem limit.
Generally speaking - VarAC community rules are to conduct QSOs in 500Hz which is more then enough for chatting. Just to conserve bandwidth and live with all the other stations around us (the Packet 105 network, the Olivia QRG etc.).
Of course one can chose to QSY and conduct QSOs in 2300Hz as an experiment but this is not really a necessity. The VarAC community is only using 500Hz.
