ON3JT

Having built two monoband SDR kits, it was time for something new. The Softrock Lite II receiver kits are working fine, but I wanted something that covers more. The two monoband kits are made for 30m and 40m.With my soundcard that samples at 96 kHz I can see/hear the whole 30m band, on 40m however I can only receive the lower part of the band.

My top 5 of my best dx using wspr. On 20m the antenna is a half wave vertical. On 80/40 and 30m I used the Diamond W735 with an extra dipole for 30m. This antenna hangs just 2 meter above the lawn.

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/

It has been a while that I posted something on my blog here. Don’t panic, I’ll try to do it more frequent.
I’ve been busy with all kind non-ham related things.

But yesterday I managed to find a free moment and put the transceiver on the 20m psk band. Around 20:40 UTC I noticed a qso that needed more attention.

From left to right :

1. The kit has just arrived.
2. The PCB, nice and clean job.
3. What I did in january.
4. Where I stopped in march.

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.
