SV5/HB9COG, KM36xa, Kiotari, Rhodes

2021 DXpedition

Update 15. September 2021

The station is checked and packed. So technically we are ready to go. Covid-19 situation is still difficult and changing almost daily. We are monitoring the situation closely. If nothing bad happens we will be flying 27. September to Rhode Island. Keep the fingers crossed for us! More information when there are any good or bad news.


Update 2. August 2021
Due to Covid-19 we had to postpone twice our DXpedition to Rhodes, the mayor island of the Dodecanes. Although the situation still isn’t perfect, we will be on the island for 14 days (from 27. September to 11. October 2021), for some sightseeing/vacation and of course EME on 432 (QRP only), 1296, 23xx, 3400, 5760 and 10xxx MHz.

The house on the southeast side of the island is booked, so are the flights from Zurich to Rhodes and back. Team members are Sam HB9COG, Dan HB9CRQ and Sue Dan’s YL.

Our QTH is in KM36xa, directly at the beach. So, MR should be perfect! For MS we expect some 10 to  25° elevation due to houses nearby, some trees and the mountains at the horizon (we will only know exactly once we are there). But in anyway, we should have good enough MS to work the US-Westcoast.

CW: Although it is on the limit, we will work CW on 1296-10450 bands. However only with big-guns and after the pile-up on Q65 is worked.

1.5m dish 1x2mm mesh, homemade automatic az/el control:
1296: 50W at feed, circular, preamp at horn
23xx: 50W at feed, circular, preamp at horn
3400: 50W at feed, circular, preamp at horn
5760: 50W at feed, circular, preamp at horn
10xxx: 50W at feed, v-pol, preamp at horn

432: 50W at dipole, 1x11el FLA, preamp

We will be using WSJT-X 2.5 on all bands. On 70cm Q65B with Doppler Control (“Own Echo”, in other words we listen on our own echo). On 23, 13 and 9cm Q65C with Doppler Control (“Own Echo”). On 6 and 3cm Q65D with Doppler Control (“Constant Frequency On Moon” and if necessary “Full Doppler to DX Grid”). Hopefully more people take advantage of automated Doppler control. Especially on 6 and 3cm it is a MUST for successful QRP operations.

We’ll have internet access. During our activities we’ll be stand-by on the HB9Q band loggers. We also will check our e-mails several times a day.
