General Radio Discussion / Get a christmas E-QSL card :-).

« on: December 03, 2014, 0823 UTC »

Hi here  ..

48 meters in winter times..:
During the daytime we reach the middle and south of England to Holland and Belgium, around of a circle to north Germany, Poland, Estonia, Latvia, Lithuania, southern part of Finland and the middle of Sweden.
At night moves the ring south on (getting bigger) and now France, Spain, Portugal, Italy, Greece, Ukraine and the southern parts of Russia joins.
We will test whether this still fits with a 'Christmas test'.
Therefore we transmit Saturday and Sunday afternoon (6/7 2014 at 13 to 15 UTC) and again both days from 21 to 23 o'clock UTC on our usual-frequency '6263.5 kHz' in the 48 meter band.
So if you want to acquire a Christmas QSL cards from us, then you must plug the receiver into the high gear and send us a report.

General Radio Discussion / Test on 48 Meter..

« on: August 24, 2014, 1141 UTC »

Hi here  ..

Tonight we will start testing our new 48 meter system and antenna. We see ourselves on Utwente SDR which is a good start.

We start 20:00 UTC (22:00 European Summer Time) and 2 hours until 22:00 UTC. It happens on our test frequency 6263.5 kHz. with somewhat mixed music.

Our output is about 800W PEP on a vertical antenna, 4 meter high with coils on a 'little hill'. Our physical position in Denmark is North Zealand, the Hillerod area (see Google Map).
Reports are very welcome here, or on our Mail 'radiooznrh'a'gmail.com'.

So if you want to get a really DX station, so you have the possibility now . We acknowledge with an electronic QSL cards

The RF Workbench / Don't use a LP filter, use a Diplexer instead..

« on: July 27, 2014, 1105 UTC »

Hi here 

What happen with your harmonic in a normal LP filter? They are sending back to your PA transistor as 'mismatch and heat'. Therefore send them to a separate 'harmonic load' instead, this is what a Diplexer do.

Hi Here, hope I'm write on the right place on the forum .

Right now we do some test transmissions (almost every night) on 1616 kHz. at 21 UTC (23:00 European summer time) and one hour to 22 UTC. We transmits with 500W PEP and 'often visible' on Utwente SDR (as a little pip ) .
So if you have a good antenna and radio, we would be happy to get an report. We acknowledge with an 'electronic' QSL cards.
