S21DX IOTA AS-140, December 2022


Islands on the air

For our last year’s IOTA AS-140 activation – We had to reduce the number of stations from our initial planned two to a single HF (as we couldn’t manage BPF, struggled to arrange other essentials like batteries, generators etc.). This time we started planning early and hope to manage all the BPF/Telescopic masts and other essential on time.

In 2022 we are planning to activate AS-140 from a different Island [Island’s name will be published once we get approval from authority]. Planning Three (3) stations, Few more better antennas (Beam, VDA, Beverage), and our loved multiband vertical with 80m steroid – which was used for the 5000+ qso barefoot. We are planning to use a linear for SSB Phone if we can buy a larger 2000VA 3000VA generator. We will also try to invite more interested S2 operators if we find with adequate experience (interested Bangladeshi HAM Click here and apply before 30th April 2022).

QSL Policy:
Similar to our 2 past IOTA, we will NOT monetize QSL to fund the DX-pedition. Paper QSL will be handled by our good friend David EB7DX who acts as our QSL Manager for last 15+ years. Please check EB7DX website for more detail about QSL service. All QSO log also will be uploaded in LoTW and ClubLog immediately if not during the activation. No need for contribution for LOTW/CLUBLOG confirmation (It’s free) – but your support NOW can help us prepare better which will increase your chance of having a QSO with us.

  1. Hello!

    I was very excited to learn that you are going to activate an island in November! Islands are GREAT because you can often find a good location where you can beam directly out over the ocean to the east during your moonrise S21 has NEVER before been activated on 6m EME, and I am VERY INTERESTED to set up a Q65 mode sked with you on 6m during your moonrise!

    I have attached a file showing your moonrise periods when we both can see the moon at the same time during November. The days with lowest Degradation (in the middle of the month) are the best days for 6m EME. If you can tell me exactly where you are planning to operate, I can provide more precise moon positions and times for you, but the times shown are for Hatiya Island, and should be very close for any of the nearby islands.

    PSE let me know what power and antenna you are planning to use on 6m, and if you can be QRV any of these times for a 6m sked with me. I look forward to hearing from you!

      1. I hope you plan to operate some other than Europe. I live on the East Coast of NC USA and it next to impossible to work you through all the Europeans. Have a safe and successful trip. I hope to work you. KC3X
