on 5809.9+
1603 music, fair, but sounds somewhat dull or bassy, signal too low to be sure,
1608 next, maybe modulation level could be pushed higher ? nothing quite sure
1610 "Putting on the Ritz" , 1613 talking (no copy), then some rap
1653 pops, same results, 1658
1832 talking, music background, R.Caroline recording or story (DTI, Ross Revenge, etc), 1845

(1936 no signal)

Thanks Ray and cj468.
Yes, audio level was a bit low. This will be fixed in the next week or 2. I need a new audio amp.
The new mod transformers have a bit more bass than the old ones but they are capable of a lot more power so im hoping that the transmitter will sound better when I sort out the bass issue.
More tests over the weekend.
