I am very happy to announce, that on 6th of May 2018 I got official
invitation to join the 4U1ITU team for EME operation. It will be
7 bands EME activity in cooperation with 4U1ITU team (Attila
OM1AM and Nick SV3SJ) andBraňo
got a special - time limited permission from the OFCOM to work
all bands EME.
Permission is not valid for terrestrial transmitting !!!
In the main time we will work first all
stations by CW, than when CW traffic slow down, we will be
also to WSJT for all stations interesting to work us in that mode too. We
are able to switch between CW and JT according request if not so busy in
QSOs. We expect to have chance change also bands if not busy on
During ARRL EME
contest, first Moon pass we will be QRV 5760 MHz ! Means that not
only from 00:00 UT on Saturday, but from our Moonrise in Friday around
19:25 UT. We expect to have clear horizon for East and will
work in maximum length of our Moon window. Moonset part is behind ITU
tower, see picture. Than we exchange TRV for 10368 MHz
and will be QRV next Moon pass in contest on 3cm. Sunday
we will change TRV and will be QRV on 24 GHz again full Moon pass
till Moon will be behind building.
On 432 MHz we can turn V or H pol !!!.
2,3 GHz - With RX unit we will cover all existing ham
radio frequencies on EME and
expect to work everybody from Australia, Japan, EU and USA. We will
TX only 2320,100 and 2304,100 !!!
10 GHz - courtesy of Yoshiro JA4BLC we will be able to RX
on 10450 MHz,
on TX thanks to Mirek OK2AQ we will have 50W RF and new very precise
thanks to Eddy ON7UN. New 24 GHz band will have
around 15W RF.
We prefer QRG xxxx.100 on all bands.
On 432 - 2320 MHz bands we will use WSJT 10 and
3400 - 24048 MHz WSJTX with Doppler
shift correction. Do not forget to put our call sign
JN36BF to the WSJT data
base. Check WSJT work condition described byRene PE1L
No chance to have permission
to work on 144 MHz and other bands !!! Also terrestrial transmitting
is not allowed under our OFCOM permission !!!
Some tips to help
us to QSO with you on JT65
Add us to Call3.txt
Please call us when you CAN copy us. No need
to have a good decode from us,
You will decode us when we call you. Usually
you can't decode signals -24 till -31 which are not for you, you
see a # indicating we call someone else
You don't need stop calling us when we are in
QSO by JT65 with someone else, after a QSO we will call the next station
but only if he was TX'ing the period before.
Don't hop around QRG, choose a freq to call
us and stay there for a while. If you stop TX'ing, listen the
next period and then change freq if you want.
We will not TX 73, if a QSO is
complete by RX'ing 73 from you we call CQ or another station.
(QSO is complete if both stations received both calls, a report
and one or more R)
You need to send 73 after you got our
RRR, its good to know for us that we can call the next station.
We don't have a special station and we can't
make more then 10 qso's a hour, it takes patience to QSO with
More and more stations are locked at 10 MHz,
keep in mind you can end on top off each other at 144 MHz. Use
If you are familiar with the `Lance
Procedure` you can call us that way.
Some tips to help
us to QSO with you on EME MW JT4F and QRA64
Add us to
We have available WSJT-X v1.8.0rc2
WSJT-X connected to IC9100 allow us to work Full
moon Dopplercorrection if you do not have WSJT-X connected with
your transceiver. In this case you will TX and RX on same QRG and we
will handle full Doppler correction also for you, but we need to
know your locator!
We will prefer on 9 - 6 - 3cm CFOM -
frequency on Moon) allow to all others monitoring our traffic. All our
units are GPS locked, we will be exactly on our presented QRG.
and 24048 MHz
we will mainly use QRA64, JT4F we are able to do according
During MW operation ( QRA64 or JT4F ) - IF YOU SEE we call
somebody, please stop to call us till our 73! to avoid interference
and extending time for QSO !!! Thank you !!!
Some tips to help
us to QSO with you on CW
PLEASE keep all the time 1 min. periods
If you hear that we call other station as is your
call, PLEASE stop calling to our 73!
If you copy WE call for example G3???? YYYYY
call me back in divided groups like GGGGG 33333 LLLLL TTTTT FFFFF
to more easy copy your call, do not give us our call, we know
Please try to call us with little be QRG spread,
we have SDR and we will see you are up or down of QRM on echo QRG
For CW and JT65B and C we will always
RX on our own echo!
