Hi all, For anybody looking to buy one of the EDM Design FM Transmitters, until the end of August there is a promotion for free shipping (normally US$15) and a free 'rubber duck' antenna (normally US$12). It may only be a saving of US$27 but that is US$27 in your pocket to spend on something else . To take up the offer you'll need to send an email to email@example.com with what you want to buy, instead of using their website. Don't forget to mention you are an AusChristmasLighting member, as this offer is only for Christmas lighting forums and communities. EDM transmitters do cost more than what you'll find on eBay but they allow for variable adjustment of the output power, from as low as 1mW to as high as 100mW. Please note that EDM transmitters are sold in a kit, and to complete it you'll need to solder on the DC power jack (included).
