I came acros the site of IK0VVE with a wonderfull description of a MEPT.
MEPT stands for Manned Experimental Propagation Transmitter and is usually very low power. He uses a crystal oscilator but I find them pretty expensive. So I Looked around the net for programmable oscillators. Those are even more expensive and in the most cases you need a microcontroller to programm them. The oscillators uses I²C for setting the frequency by setting the divider and table lookups, …..

I noticed today that the Software Defined Radio from Twente University now has six bands to play with :  0-150 kHz, 1790-1930 kHz, 3500-3760 kHz, 6990-7135 kHz,  10030-10175 khz, 14000-14290 kHz.
But it lasts only a few days, so enjoy : http://websdr.ewi.utwente.nl:8901/

More to come.

Today, I saw Daniel LU3DXI calling cq in PSK125. PSK125 is faster than PSK31, so you have to speed up yourself to read and write the qso :-)

The distance is a personal record at the moment : 11349 km (the locator is GF05RL, not GF05IA probably some QSB).
QSL card is heading Argentina.

I was monitoring the 20m PSK31 band and saw this guy calling CQ :

You all know YouTube but it has now a competitor focussing on ham radio and it’s called CQtube.
