S21DX operation from Char kukri-mukri island this december
The island is some 400km away from the capital and is situated in the south coastal belt of Bangladesh. There is some limited settlement there, and no electricity. We have selected the remote southern tips of the island for our camp. Though the lack of electricity is a challenge for us but at the same time that is a blessing – less interference.
In Bangladesh there are not many operators who are regular with HF operation, mainly the listening skill is rare. The main operator for this expedition will be S21AM and S21RC. Another op S21D shows interest but not confirmed yet. This will be a small station in a tent, run by battery and backed up by 2KW gasoline generator to top up the batteries and laptops.
We will operate two station (100w), antennas will be one multiband beam, two verticals and 1 multiband inverted V. We will mainly operate SSB voice on 10m, 15m, 20m and some 40m if propagation permits. Why no CW? because we forgot CW. Why no Digital/FT-8? because we hate computers doing the QSO. As we couldn’t manage Bandpass filter and not enough support, we will have only one HF station running with a multiband fan dipole and fan vertical.
Considering propagation and our poor setup (no beam and no Linear) we decided to run FT8 (preferably in Fox/Hound mode).
The main challenges are as only two operator we can not operate the station 24/7 as we need to sleep, eat and do errands. There will be 4 non-ham volunteer to manage the camp, seeing logistics, answering email and posting updates etc.
The only equipment we are looking for is some bandpass filters (20m, 15m, 10m, 40m) , so that we can operate both station simultaneously when there is good propagation.
QSL will be handled by our QSL manager David EB7DX. Please check his website for detail. QSl will be direct or via bureau through EB7DX. Also will be available in LoTW.
PLEASE do not send us QSL to Bangladesh. All QSL goes to EB7DX in Spain.
The initial budget of this dxpedition is set to US $4000.00 to $5000.00, the operators will cover the expenses of transport, food and logistics themselves which is somewhere $2000.00, rest of the fund we are looking for community support. Mainly we need to buy the generator, two batteries, fuel, pipes for the antennas. Also we are looking forward for some Band Pass Filters, we will be able to operate two station simultaneously in this way. Please check the Our Sponsors Tab for detail or talk with our manager David EB7DX.
Support us to activate s21dx
