This decode is via the  twente  web-sdr  ... ok not quite  100 % .. but -30  dB is well into the  system 'red'  I assume  we are looking at the  slow  qsb taking the signal  under the  noise floor ? ....

LF,

Not able to reply to any calls from now but the beacon will continue until about 2300utc.

I will resume tests tomorrow (Friday) night & increase power for greater distance.

Hi LF,

I am increasing the PTT loop timer to provide a 5 minute increment of the beacon.

This will give operators lots of time to create a reply or call. My beacon will stop & notify me if a reply or call is made.
