WBGO and WFUV are fundraising simultaneously

I understand that not for profit radio stations must have fundraising drives or else they could not operate.  I wish that such stations in the same market would coordinate their drives so that would not conflict. Perhaps there is not much overlap in the listenerships of the 2 stations. WBGO is completing their 3 week drive, while WFUV's just started last Saturday.  I do make donations to both once a year.   I donated to WFUV last week, while I will give to WBGO next winter.  They both provide programming not heard on terrestrial radio in the NY/NJ area.
