I thought I would share with you some initial tests of DATV-Express operating
at 146.5 Mhz. This is the exciter only, I will post some results of it combined
with a G.H Engineering brick based PA in a few days. These were taken with a
Rigol spectrum analyser. There was no additional filtering on the output.
The new FPGA code uses a x64 interpolater, it will only operate between about
100K and 400KS/s but this should be fine for the 2m DATV tests.
I was able to lock to the signal with an MER of around 28 using Tutioune with a
TT-Budget S2-1600 card. Work progresses on developing a matching
