Version 1.0 amd version 1.1 of RFM22B

Hi I am new in this Forum
Hello every one!!!

I am trying to use a code that was running OK with version 1.0 of RFM22B

Last week I purchased some new boards and I cannot get running the code, which is a simple loop, which send just one character every 2 seconds.
I am monitoring the the interrupt bit which indicate TX was done, with a led, so there is not RX board in this case.
I cannot get running that loop continuously because it stop some time after 20 times , 3 times etc. the number of cycles is random.
I review both data sheet version and I did not find difference except that they add a new frequency available which is 470 MHZ.

Can anyone help me with that?

Thank you in advance
