Bidding has been fierce on many of the nearly 300 items available in the 11th Annual ARRL On-Line Auction, which continues through Thursday, October 27.

This year’s auction inventory includes some vintage ham radio items, including a Collins S Line, which has been attracting many bids. Among other premier items from the QST “Product Review” stock are the new Elecraft K3S HF+6 meter transceiver, an Ameritron ALS-1306 HF/6 meter amplifier, and the new Icom IC-7300 HF+6 meter transceiver. Also on the block is a RigExpert AA-230 ZOOM 0.1-230 MHz antenna and cable analyzer, and an autographed script from the TV show “Last Man Standing,” starring Tim Allen, KK6OTD.

There are books and publications — including many vintage editions of the ARRL Handbook, among them a special 1942 defense edition and a 1926 edition. Bid on embroidered ham call sign caps and ARRL-branded gear too, from playing cards to iPhone chargers and even glassware.

Proceeds from the yearly On-Line Auction benefit ARRL education programs. These include activities to license new hams, strengthen Amateur Radio Emergency Service (ARES) training, offer continuing technical and operating education, and create instructional materials.
