Hi Uwe,

I wasn't aware that you could use Jason with a class D Tx (G0MRF 300 w),
please tell me briefly how is it done?

2 x 100r 100 watt resitors should arrive tomorrow ((wed 2nd) so I will soon
be testing the modified G0MRF PA.

Also started re-building the LF antenna after storm dammage.

-----Original Message-----

so I learned: using JASON into a class D push pull PA (G0MRF version) you
have
to switch the TX shift multiplying factor to 2. if you dont the transmission
bandwidth is 16Hz only (factor 1 = 32Hz bandwidth is norm).
