The following is a random assortment of IRLP-
Now and then, someone reports having incoming audio that misses syllables, or "skips".
If this happens to you and you don't think it's packet loss, are you running a Linksys
router? The Linksys router has been shown to cause this problem when "Logging" is
turned on. Log into your router and check under the Administration tab, sub-
Make adjustments when you're SURE "readinput" is not detecting DTMF... or thinks it does (parallel port set wrong, in a hurry to set levels, and forget to get DTMF working first).
If aumix has saved "odd" stuff or is behaving inappropriately:
Make sure you're not connected to another node or reflector.
aumix (and set levels where they should be)
Save the aumix settings
Usually clears it all right up. But you have to make sure DTMF is working properly first and that you're not connected anywhere when you do this.
How do you control your node while the other side is talking? If it's a simplex node, you can't, except via a terminal. Why would you want to? What if someone connects to your node and starts abusing it? What if you want to stop the playback of long bulletins after they've started playing?
The node ignores DTMF unless the COS is active. By default, on a version 3 board,
there's a jumper that blocks the COS signal while the PTT is activated. By moving
the jumper, you enable the COS signal to be passed to the IRLP software, even while
PTT is keyed. This allows a full duplex radio (i.e. a repeater) to pass commands
to the software. The jumper is labeled PTT LCKOUT (not a typo). Just move it from
one end of the 3-
From the archives:
Full duplex control is already optional. Just move the "PTT Lockout" jumper on the interface card. All nodes directly connected to repeater controllers or with full duplex RF links should be set this way so you can send control commands into the node while it is transmitting. Extremely handy for disconnecting from busy reflectors or locked up nodes
