I doubt it will meet adjacent channel, and in-band noise community expectations.

What is the noise level 10kHz  and 100kHz away, in an SSB bandwidth ?

(dont measure in 1Hz BW, measure in the wide band and convert)

Thanks David for the news.
One question: how high can the Pi transmitter go in frequency?
Our 70 cm band is pretty crowded, but the 23 cm band and 2305-2400 MHz
bands are underutilized and we want to make use of them. The Pi/RTL
system is a good candidate because of price.
