[arm-allstar] What does linktolink do??? was: TX Inhibit

[David McGough]

Setting linktolink=yes applies to simplex nodes (duplex=0 or duplex=1)
ONLY.  The major issue that setting linktolink=yes resolves is that it
allows the the simplex radio's PTT to be activated by a connected
full-duplex node at -any- time, even when the simplex radio's COR
signaling is active.

So, this is useful in several scenarios. First, lets say you've got a 
remote-base tuned to a local repeater. During an active net, the local 
repeater might never stop transmitting, keeping the remote-base COR 
continuously active. Without enabling linktolink, a full-duplex node 
that's connected to the remote-base can NOT ever cause the remote-base to 
transmit (PTT is "locked out", COR has priority).

A second scenario is where you've got a HF rig and you want a linked 
full-duplex node to trigger the PTT of the HF rig at any time, even while 
the HF COR signaling is active.

linktolink is a "have to have" parameter for connecting multiple radio 
systems over analog RF!
