Last saturday night my computer has been running all night long the WSPR (whisper) software from ….. to see if I could receive that mode too. My wife had the night shift in the hospital and could not argue that the computer is making too much noise in the bedroom :-) That is the downside of having the shack in the bedroom.
I set the receiver to 10.138.7 in the 30m band and went to bed.

I’m currently experimenting with a PIC processor. The term microcontroller is actually better, but you know what I mean. It all started when reading about the bitx20 kit. This transceiver has no frequency readout and if you look around you’ll notice that everyone is using a PIC or an AVR to build a frequency counter with LCD readout. I knew little about PICs, nothing about AVRs. Not that I dislike AVRs but PIC feels better to me personally.

After reading this site : http://paginas.terra.com.br/lazer/py4zbz/hamdream/rxdrm.htm I modified my Icom IC725 with a similar capacitor. It worked more or less. Switching to the CW-N mode on my trx and decoding with Dream I could listen to some DRM radiostations. At that time the only antenne I could use was a magnetic loop, mounted near the window. Not the setup that everyone dreams of :-)

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.

My most ill prepared attempt ever.
I took my laptop and my BBB4 receiver and some wire as antenna.

More to come.

It was a long weekend and the weather was fine. Sunny and warm. Time to test the 40m antenna.
Note for myself : build or buy an antenna analyzer. Try not to dismantle the whole shack for antenna testing again.

First thing I did at my parents is to solder all amp connections. Then assembled everything together and started searching Read the rest of this entry »
