Hello Jean-Pierre and all others interested in MF-reception,

first of all thanks very much for everyone who has send a reception report
so far. Up to now I received reports from all over Europe (PA, F, DL, OZ, G,
I, SV, SV8?, EA).

The current ERP is around 5 Watt, probably a little bit less, I need to
confirm this by a measurement later.

It might be interesting if you could check the signal strength in relation
to a few NDBs nearby my qth, I plan to do some field measurment to confirm
their ERP.

Braunschweig, BRU, 427 kHz
Celle, CEL, 311 kHz
Hannover, HA, 320 kHz
Wunstorf, WUN, 419 kHz
Hannover, HW, 358 kHz
Hannover, HAE, 332 kHz
B�ckeburg, BYC, 368 kHz

I plan to have a special QSL printed to confirm all receptions of DI2BO.

Currently DI2BO is transmitting on 440.040 kHz. This frequency has been
coordinated with Walter, DJ2LF / DI2AG to allow to observe and compare both
beacons (DI2AG on 440.044 kHz) once we do simultaneous transmissions in
QRSS.

At the moment the CW speed is around 10 wpm, I am using an old mechanical CW
generator that once was used to key an NDB (there is a sticker on it saying
"Property of the German Authority for Flight Safety"). Later I will switch
to an electronic keyer once I have programmed it but I will maintain the
speed as it is for the tme being (QRSS is planned later). I plan to update
station details and transmitting schedule on http://www.qru.de/di2bo.html as
well as here on the reflector.

The beacon will run full power today and next night, tomorrow morning I plan
to switch to QRP which is about 12 dB less than what I am running currently.
I will switch to high power during evenings and night.

Best 73

Geri, DK8KW / DI2BO
