SDR Family...

SDR family on SV5BYR's shack is grow-up. Lot of tests, lot of improvments....Stay tuned.

Remote SDR Server...

The idea....

The construction....

 The final result...

The heart of remote server beats on a Raspberry Pi 4, 4GB RAM running Spyserver software and powered  with POE (48v to 5V, 3A). Only one good quality FTP cable running to the roof giving LAN and power to the system. 

LNA pull weak signals out of noise, combined with a Diamond X-200 for VHF-UHF, and a Windom 160m-6m covering the frequencies from 500 KHz to 1,7 GHz. The server is not public and it used for personal experimental use only by me.

RTL-SDR and preamplifier work....

Here it's the first block. A mini RTL-SDR (R-820T) into the same metal box with an 20db preamplifier. The preamp is powered from the same USB.

 Here is the second combination.  An RTL-SDR into the metal box and the preamplifier above...

 Final setup. A blue thermal silicone it's under the RTL-SDR to spread the heat on metal box....

New toy...

My new Antenna Analyzer just arrived...!!!

The best you can buy with this quality. Plug and play right out of the box.

The best function is that the "baby" can easily connect with PC via USB and to have the plot of SWR vs FRQ on your screen.

Testing my disconne antenna here:

...thanks SM6WHY Lasse, for his help and great software !!!

6m Sporadic E...

I miss the fun.

Happy New Year...!!

CQ WW 15m QRP...!!!

 
Weekend at my 2nd QTH. With lot of things to arrange at my mini farm. I decide last time to participate as QRP...!!! Yes. Why not. 

My last years company during contests is my youngest son Konstantinos who is very anxious for our next projects with QRP operations. 

Early the morning of first day, conditions where very strange so, I decide to get some hard work.  I leave QSOs logging and goes for ...wood logging !!! As shown at my stats both mornings spended  to woods.

Anyway I'm very happy about because this a "First Ever" participation from SV5 land on QRP category.  Band 15m, Power 5 watts.  

Here is my stats:

Not bad at all for my 5 watts and my modified Windom antenna.

Back on air...

Back on air after long time...!!! 

Some personal issues keep me out of air almost 2 months. Now Im back again in daily basis on CW, RTTY and SSB sometimes.

At weekends also I 'll be active from my 2nd QTH at south Rhodes and KM36vc Locator.   

  

See you on air...!!!
