[arm-allstar] Master ii station tone in tone out

[Justin Reed]

Tom,

I dug into the schematic and found that even the older "Versatone" 
encoder boards are capable of muting CG encode.

So, If it's an old Versatone encoder, you'll see three solder pads 
marked H1, H2, H3. These are all CG mute. You ground them to mute CG 
output. The manual states, however, that the CG will remain muted for up 
to 160 milliseconds after ground is removed, so a user will have to key 
up for that long before the CG encoder unmutes. You can run a wire from 
RUS or RX MUTE (which goes high when there is carrier + Channel Guard) 
directly to your choice of H1, H2, or H3. I have not personally tested 
this method but the logic looks sound.

The newer dip-switch encoders also have H1, H2, and H3 that function as 
CG Mute. Reference LBI-31123
Wire the RX MUTE from the receiver to one of these three pads.
KEEP IN MIND that when you ground H1, H2, H3 during transmit it will 
cause a "STE" (reverse burst) to be sent.
If you want to MUTE CG -without- the STE burst then run a wire between 
H4 and H5 on the encoder board. Whether you want STE or not depends on 
what you are using for a node radio looking at the repeater. Most ham 
rigs don't recognize STE so it drops the Allstar COS faster to not send 
STE. If you're using a commercial rig for a link, then STE might works best.

I have tested this with the dip-switch encoder and it works like a 
dream. It also doesn't have the unmute delay of the versatone board.

73,
