Hi Stephen,

What you're wanting to do is easily feasible, technically speaking.

>From my understanding, the two sections of the current rules that are the 
kicker are:

97.113(3)(5):
"Communications, on a regular basis, which could reasonably be furnished 
alternatively through other radio services."

............................
Can you direcly receive NOAA transmissions in your area?? If so, NOAA 
broadcasts are already furnished through another radio service.


97.113(c): (last sentence)
"......Propagation, weather forecasts, and manned spacecraft
communications retransmissions may not be conducted on a regular basis,
but only occasionally, as an incident of normal amateur radio
communications."

............................
The "incident of normal amateur radio communications" means the audio 
could be in the background, when a ham was talking into a mic, but even 
then only as an accident.

My interpretation was there there is some "grey area" and I argued this 
with some legal experts. Their answer was that this ground has been 
covered with the FCC, and the answer was: NO.

Please follow up with your ARRL Section manager and get an opinion, etc.

BTW, I don't agree with these rules! But, I can understand why they're 
there.

73, David KB4FXC
