Barry,
I think it's operating as designed. From the manual at
http://physics.princeton.edu/pulsar/K1JT/wsjtx-doc/wsjtx-main-1.8.0.html#WSPR
"If you will be transmitting as well as receiving, select a suitable value for
Tx Pct (average percentage of 2-minute sequences devoted to transmitting) and
activate the Enable Tx button."
It's the average percentage. The TXing is randomized to prevent two or more
stations from always QRMing each other if they choose the same TX offset and
schedule.

Subject: [wsjt-devel] wspr transmit periods random
Hi all,
I have been testing WSPR in wsjtx-1.8.0 and despite having TX Pct 33%
transmissions are apparently random.
I am seeing TX periods separated by 1,2,3 and even 5 consecutive periods
of RX. I was not in the room so was not interfering with anything.
Cheers,
Barry
