Alexander --
I have a TH-D7A and I don't know if the TH-72A works the same but 
it's worth a try --

  when I want to "force a beacon xmit now" -- (because  I  don't hear 
anyone else transmitting) --

I press the BCON button (to turn it off) and then immediately press 
it again  (to turn it back on) --
the TH-D7A transmits the packet and then starts the interval timer up.

So yes, as the K9JKM pointed out -  you have to listen for a "hole" 
and then try sending a few in rapid succession.

It looks like there is an ISS-DATA entry on ==> 
so you can see if the digipeater is on.

How are you determining if you have been heard -- are you looking for 
the indication on the TH72A ... or do you check
the site ==> http://www.ariss.net/

Don't give up!
