We have tested and packed all equipment… we are ready to go!

Because SV9 was never activated on 432 EME we have built a QRP station which fits in the existing transport-boxes of our microwave DXpedition station. We will be using 1x11y by DG7YBN, preamp and 50W with our fully automated az/el control.

Our QTH locator is KM25XA, on the southeast cost of Crete. We should have a pretty good MR and MS, we expect to have no more than 5-10 degrees of elevation.

We will be using my call sign for this DXpedition: SV9/HB9CRQ

Equipment:

432: 50W at dipole, preamp, 1x11y by DG7YBN
1.5m dish 1x2mm mesh, homemade automatic az and 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

We fly on 3. May to Heraklion in SV9. From there we drive to our QTH. The first week, before we start our EME activity, we’ll do some sightseeing. On 19. May we’ll fly back home.

During our activity we will be stand-by on the HB9Q EME loggers.

Our EME activity will be as follows:

10. May
QRV 1296.100 1st from 08.30z to 22.00z

11. May
QRV  1296.100 1st from 09.30z to 23.00z

12. Mai
23xx.100 1st from 10.30z to 23.30z
MR on 2301.990 (on request only), will QSY later to 2400.100 (on request only), later to 2320.100 and finally to 2304.100 (QSY will be announced on HB9Q 23xx logger)

13./14. May 3400.100 1st from 11.45z to 00.15z
MR on 3399.990 1st (on request only), QSY will be announced on HB9Q 10xxx logger

14./15. May  5760.100 1st from 13.00z to 00.45z

15./16. May  10xxx.100 1st from 14.00z to 01.15z
10450.100 1st (on request only), QSY will be announced on HB9Q 10xxx logger

16./17. May 432.085 1st from 15.00z to 02.00z

17./18. May frequency open from 16.15z to 02.30z

Now that WSJT-X 2.0.1 is available, we will use JT65b with Doppler Control (“Own Echo”, in other words we listen on our own echo) on 70cm. On 23, 13 and 9cm we will use JT65c with Doppler Control (“Own Echo”). 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”). Hopefully more people take advantage of automated Doppler control. 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 (but not on 432). 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?
On 70cm at least 8 long yagis and very good power
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: QSL only direct including SAE to: HB9Q, P.O.Box 133, CH-5737 Menziken

If you wish to sponsor our activity, you are welcome to do so by using PayPal dan@hb9q.ch (please mention your call).

We are looking forward to our SV9/HB9CRQ DXpedition and hope to work many of you!
Next information a few days before we will be QRV.

NEWS by HB9Q, dated 2019-05-05:

The Q-Team arrived on Crete Friday night. On Saturday the equipment was
checked, all looks well. We then assembled the station and did a short test
on 23cm, all OK.
Our QTH is KM25WA (we expected it to be XA), we have the Mediterranean Sea
just 50m south and 15m below us. The MR and MS will be into distant
mountains. Depending on declination we expect about 10°.
We have internet access, not highspeed but good enough. We were told that
there is some risk for power-outage with strong wind… so far we had
none… we hope it stays that way. However there is of course gusty wind,
as always on the cost.
We now enjoy a few days of sightseeing and will start our operation 10. May
on 23cm as announced.

Здравствуйте!
Вчера провел таки JT65c EME QSO с SV9/HB9CRQ RO/O на 13см (1.5м 50Вт). Долго не мог декодировать их слабый (-32, -29) сигнал. Dan подсказал проверить наличие их позывного в call3. Оказалось, что SV9/HB9CRQ  нет в базе. Программа WSJT10, видимо, дала сбой и не заносила в базу новые позывные. Записал вручную и сразу декод с рапортом при -29. Их RRR декодировал уже визуально по разнице частот сигнала. Меня принимали -30дБ. Мой setup: антенна прямофокусная сплошная 1.8м, увеличенная до 2.2м сеткой 8х8мм, септум OK1DFC, LNA 0.45dB NF, SSPA дает через кабель 1/2" около 100Вт в облучателе.
73! Александр

Здравствуйте!
Вчера был последний день работы экспедиции. Диапазон 23см. Для меня условия были "не очень", так как Луна уже была в отрицательном склонении и элевация не превышала 21гр. А это дополнительные шумы от земли и деревьев, которые еще и частично затеняли поверхность параболы. Тем не менее иногда удавалось декодировать сигналы SV9/HB9CRQ на уровне -29, -31, -30, -28. Несколько раз пробовал вызывать SV9/HB9CRQ, но они меня не принимали. У экспедиции парабола 1.5м и 50Вт - у меня 2.2м и 100Вт.
73! Александр

Сработал с ними на двух диапазонах 6 и 3 см. Слышно было их до -15 -16. Мне давали -21 -22. Можно и ТЛГ с ними работать. Отличные операторы Дан и его друзья. Ждем новых экспедиций!
