Hi, Alex:

 I have questions also.  Your goal seems to be:
"have a constant data stream over the radio".

I do not think that it matters that the data is numeric or other.

Why do you use radio?
Why do you use Amateur Radio?
Why do you use AX.25?
Would 802.11b ( 11 Mbps ) be close enough to 'constant' ?

The closest thing I am aware of that supports 'constant data stream',
or at least constant small delay, is ATM.

If you want 'constant', you need 'full duplex'.
 i.e. You need full duplex radios.  Perhaps a
'dual bander' capable of full duplex would suit your goal.
