update 25.10.2019
On 25. October we have been QRV 10xxx MHz. We have a total of 32 QSOs, 6 CW and 26 digital for a total of 27 initials in 17 DXCC on 6 continents.

On 25. October in the morning 50, 144 and 432 operation ended.

We are very happy to have worked all continents (WAC) on 10 GHz In one moon-pass! This is the first ever time WAC was worked from Africa on 10 GHz! We have worked ZS1LS for the first ever Africa – Africa 10 GHz EME QSO! Many thanks to VK7ZBX, JA1WQF, OK1KIR, ZS1LS, W3SZ and PY2BS!

Tomorrow morning, 26. October, we will be QRV again on 1296.100: A21EME 1st, JT65C, RX on our echo. MR at about 02.45z and MS at about 13.45z. This will be our last day of operation from A21EME.

Next update 26.10.2019

 

update 24.10.2019

On 24. October we have been QRV 5760 MHz. We have a total of 29 QSOs, 11 CW and 18 digital for a total of 18 initials in 14 DXCC on 4 continents.

Tomorrow morning, 25. October, we will be QRV 10xxx MHz from our MR at about 02.00z until MS at about 13.15z. As always we’ll be QRV CW on demand after QRA64 pile-up is worked. Look for us on the 10xxx logger. Unfortunately starting around 08z we have very poor internet access.

On 26. October we will be QRV again 1296 MHz. MR at about 02.00z and MS at about 13.15z. This will be our last day of operation from A21EME.

updaet 23.10.2019

On 23. October we have been QRV 3400 MHz. We have a total of 19 QSOs, 8 CW and 11 JT65C for a total of 12 initials in 8 DXCC on 3 continents.

Tomorrow morning, 24. October, we will be QRV 5760 MHz from our MR at about 01.30z until MS at about 11.00z. As always we’ll be QRV CW on demand after JT pile-up is worked. Look for us on the 5760 logger.

Next update 24.10.2019

 

update 22.10.2019

On 21./22. October we have been QRV 23xx MHz. We have a total of 24 QSOs, 5 CW and 19 JT65C for a total of 20 initials in 13 DXCC on 4 continents.

Tomorrow morning, 23. October, we will be QRV 3400 MHz from 04.00z until MS at about 11.15z. Since there were NO requests from VK we will NOT be QRV for MR. As always we will be QRV CW on demand after JT pile-up is worked. Look for us on the 3400 logger.

update 21.10.2019

On 20./21. October we have been QRV 1296 MHz. We have a total of 66 QSOs, 3 CW and 62 JT65C for a total of 63 initials in 24 DXCC on 5 continents.

On 23. October we will be QRV 3400 MHz. Is there any VK-station who wants a sked? Please e-mail me no later than 22. October 14.00 UT. If there is no request we will not be QRV for MR on 23. October. In that case we‘ll start our 3400 MHz activity at 04.00 UT.

 

update 19.10.2019

All team members and all equipment arrived well in ZS6. All is on schedule. Departure to Botswana on Sunday 05.00 local time. More info when arrived in A21.

update 16.10.2019

All equipment is tested, packed and ready to fly from Zurich to Johannesburg on 17. October. Next update on 19.10.2019.

update 10.09.2019
To give you enough time to prepare for A21EME on MICROWAVE (23-3cm) please find here our planned activity schedule.
Unfortunately Sam, HB9COG will not join us for this DXpedition. Due to heavy workload at his business he has to stay home and work. Dan HB9CRQ will be supported by Susanne, his YL, and of course be the whole A21EME team.

We expect to have a pretty good MR (about 10° el) and MS (close to 0° el). This gives us good moon windows for all continents including US westcoast. We will confirm this when on site.

There should be internet service on site, so we will be stand-by on the HB9Q loggers (1296 to 10xxx MHz).

We will be using again our proven DXpedition equipment:
1.5m dish 1x2mm mesh, homemade automatic az/el control
1296: 100W at feed, circular, preamp at horn
23xx: 90W at feed, circular, preamp at horn
3400: 80W at feed, circular, preamp at horn
5760: 80W at feed, circular, preamp at horn
10xxx: 50W at feed, v-pol, preamp at horn

18. October: we’ll arrive in Johannesburg (ZS6) where we’ll meet the other DXpedition members at Johns ZS6JON’s QTH. John did provide all work to get the licenses and find a suitable QTH. He prepared everything for a smooth run during the DXpedition. Many thanks John!
20. October: the A21EME team will drive in a convoy of 5 to 6 cars to Botswana. This is a 5 hours trip. There we will have to do all needed customs paperwork and physical checking. From there it is another hour by car to our QTH (KG25WK) north of the city of Gaborone. We will arrive early afternoon and immediately start to build the station to become QRV on moonrise late evening same day.

The microwave EME activity will be as follows:

20./21. October
QRV 1296.100 1st JT65C from about 23.30z to 09.20z on 21. October

22. October
QRV 23xx.100 1st JT65C from 00.30z to 10.30z
2301.990 1st and 2400.100 1st (on request only, will be announced on HB9Q 23xx logger), for US-window 2304.100 1st (QSY will be announced on HB9Q 23xx logger)

23. October
QRV 3400.100 1st JT65C from 01.20z to 11.30z
3399.990 1st (on request only), QSY will be announced on HB9Q 3400 logger

24. October
QRV 5760.100 1st QRA64D from 02.00z to 12.30z

25. October
QRV 10xxx.100 1st QRA64D from 02.50z to 13.40z
10450.100 1st (on request only), QSY will be announced on HB9Q 10xxx logger

26. October
1296.100 1st JT65C from 03.30z to 14.40z

27. October
Not QRV because we have to dismantle and pack the station (we need to do this with daylight) for an early morning departure next day.

Now that WSJT-X 2.1.0 is available, we will use JT65C with Doppler Control (“Own Echo”, in other words we listen on our own echo) on 23, 13 and 9cm. On 6 and 3cm we will use QRA64D (if necessary JT4F) including Doppler Control (“Constant Frequency On Moon” and if necessary “Full Doppler to DX Grid”). Modes will be announced on HB9Q loggers.
Hopefully more people take advantage of automated Doppler control which WSJT-X offers. Especially on 6 and 3cm it is a MUST for successful QRP operations.
Although it is on the limit, we will work CW on all bands. However only with big-guns and after the pile-up on JT/QRA is worked.

How big needs your station to be to work us?
We’ve worked several stations the sizes the following list shows, so definitely we can even work smaller stations:
on 23cm 2m dish and 150W at the feed
on 13cm 2m dish and 100W at the feed
on 9cm 2m dish and 50W at the feed
on 6cm 1.5m dish and 80W at the feed
on 3cm 1.2m solid dish with 40W at the feed

QSL policy for 23-3cm: QSL only direct including SAE to: HB9Q, P.O.Box 133, CH-5737 Menziken
If you wish to sponsor the 23-3cm activity, you are welcome to do so by using PayPal dan@hb9q.ch (please mention your call). If you like to sponsor 6m, 2m and 70cm activity please use PayPal info@pa3cmc.nl
We are looking forward to the A21EME DXpedition and hope to work many of you!

Next information about the microwave part of the DXpedition will be posted a few days before we will be QRV.
