The largest club in your area is the Long Island Mobile Amateur Radio Club (http://LIMARC.org
), which will be holding an indoor Hamfair (flea marketing) not far from you in Levittown on Sunday, February 24th (http://limarc.org/fest.htm
For information about selling your gear at the event contact LIMARC's president, Richie, K2KNB (email@example.com
For help in determining the value of the equipment, contact Lew, W2BIE (firstname.lastname@example.org
) who is a member of the club's board of directors and a retired salesman at a major amateur radio equipment dealer. He takes great pride in protecting again what he calls "vultures" who swoop in on estate sales and grab up ham gear at low prices from families who don't know its worth.
You can also contact Richie and Lew by phone. You can find their numbers at: http://limarc.org/officers.htm
To save yourself the trouble of selling the gear, you also could donate it to LIMARC, which is a 501c3 non-profit, and which will provide a receipt for the "fair market value" that you can take as a tax deduction.
Best of luck.
