The voter does not react to squelch open in some cases

I've played a bit with the voter configuration and found out a problem that occurs sometimes. My configuration (at the moment) is a svxlink-base and one remotetrx. The remotetrx is the relay-station with RX and TX and the base has only a RX (I have my reasons why I have done it in this way ;-). I've running the version 1681.

Here are some log entries:

remote-TRX:

Tue Sep 22 19:14:31 2009: Voter: The squelch is OPEN (QuantarRx=107.506)
Tue Sep 22 19:14:36 2009: Voter: The squelch is CLOSED (QuantarRx=4.09622)
Tue Sep 22 19:14:38 2009: Voter: The squelch is OPEN (QuantarRx=74.4778)
Tue Sep 22 19:14:51 2009: Voter: The squelch is CLOSED (QuantarRx=-4.20453)
Tue Sep 22 19:14:53 2009: Voter: The squelch is OPEN (QuantarRx=97.0731)
Tue Sep 22 19:14:53 2009: Voter: Mute(true)
Tue Sep 22 19:15:20 2009: Voter: Mute(false)
Tue Sep 22 19:15:22 2009: Voter: The squelch is OPEN (QuantarRx=75.9478)
Tue Sep 22 19:15:46 2009: QuantarTx: Turning the transmitter OFF

The last two lines show that a strong signal is being received but it isn't detect by the svxlink base. It happens often, if a strong signal is received by the base first and a weaker signal later by the remotetrx.

svxlink-base:

Tue Sep 22 19:14:38 2009: Voter: The squelch is OPEN (QuantarRx=73.2107)

The same problem showed when configuring a system with two remote RX and one local RX.

1. If ALL RX Squelches opens, the Voter selects the strongest one.
2. Next time, ALL RX Squelches OPENs, same RX is chosen.
3. ALL RX SQL opens again, same RX opens.
4. ONLY one Squelch from another RX opens, nothing happens in svxlink (shows ok in remotetrx).
5. If the last chosen (and working RX) opens ONLY, one time, the fault is "reset".

It should be possible to reproduce easy, but maybe not to fix... ;-)
