Jerry,
Under the specified conditions, transmitting into a dummy load with tune
power set to 20W I see "High SWR" reported on the panadapter window when
"Enable X2 TR sequencing" is enabled. The "High SWR" indication is NOT
present when this option is disabled.
The same behavior was observed with 2.0.6.
I did not observe the problem with 1.16.1
PowerSDR 2.0.16/2.0.6/1.16.1
Windows XP SP3
Intel Core-2 Quad
Delta 44

PROBLEM: "HIGH SWR" displays in the panadaptor panel with tx when no

condition exists.
Condition occurs ONLY when "Enable X2 TR sequencing" is enabled (Setup
- General -
Options).
X2 TR is used to switch amplifier or other devices into TX mode, so
might not be noticed normally by
barefoot users, but anybody should be able to verify the problem.
To observe problem, using above hardware/software, enable X2 TR
Sequencing per
above setup panel sequence and click on TUNE. High SWR condition is
indicated.
Disable X2 TR sequencing and click on TUNE - problem goes away.
Problem does not occur at all with PowerSDR 1.18.6
My configuration: SDR-1000 with PA, PowerSDR 2.0.16 Beta, XP 32 bit
Media Center Edition
with SP3 in eMachines T5216 computer, Delta-44 sound card and Flex
supplied
parallel cable.
Please post your results here.
