DFMA Group Purchase from Ed Fong - WB6IQN
At our July meeting, Ed Fong, WB6IQN, presented a program where he discussed his antenna designs and his latest triband antenna.
At the end of his presentation he listed a few items that he is selling and suggested he would pick up the shipping for group orders.
The two items that seemed to attract the most interest are his triband antenna, TBJ-1, for $60 and an HF SSB handheld SDR based receiver, the GP5/SSB, for $60.
Chuck, KW4KZ, has agreed to coordinate the group purchase. When compiled, he will send off the order with a DFMA check. You can then make your payments to the DFMA. Chuck’s email address is
chanoia33 at gmail point com
