[aprssig] KPC 3+ and Peet Bros 100 interfacing

in the KPC-3+ there is option to clear data after sending. So, good solution 
for Packet Mode with 5 minutes intervals is to set something like:
BLT 1 EVERY 00:00:30 CLEAR
Then wx data is sent by TNC not later than 30 seconds after receiving from 
Ultimeter. Also buffer is cleared if there is no data from weather station 
and no any packet with old data is on the air.
