Some 30 years ago this picture was received from Venezuela on early SSTV. Then no home computers could handle the speed needed to display the picture, no re transmitted using modern software MMSSTV.

A DX Contact!!! See me make contact with a Russian amateur station. With a little luck (20 meters was pretty much shut down at this time) I was able to make the good DX contact. Hope you enjoy!!!

With the use of 2 sound cards and WinPSK, KGKSDR decoding BPSK31 on 40m

Softrock TX/RX v6.1 with KGKSDR slowly tunes across the 40m contest stations on 3rd Nov2007 using a LSB filter.

One station sits tight within the filter passband,another LF of him spreads wide.

Winrad used to look at MT63 or another multi tone data mode and PSK31 on 40m. Four PSK31 contacts are occupying less bandwidth than the one multi tone signal.

Using 2 sound cards we feed the SDR signal into CWget to decode the received Morse.

Softrock TX/RX v6.1 looks at 40m SSB during a contest. Some stations just think that if they over do the drive they will sound better and work more stations. Does spreading your power over 3 channels   more...improve readability or just make you unpopular.  less

Slow Scan TV using my Yaesu FT-847 on 14.230Mhz (20 Metre Band)

Although we can now send pictures via e-mail,
What Fun it is to send and receive them via Radio with the Only thing between you and the other   more...person is the Air we breath!! :-)

SSTV is a method of Sending and Receiving Pictures via Radio.

The Pictures I received was from a Radio Amateur in Spain Call sign EA5FO,
He was making a general CQ call for another Amateur to contact him and exchange pictures.

The Pc is used to decode the signal and display the picture in the software,
Slow Scan software used was MMSSTV.

All I used for this was my Pc mic that I put on top of my Radio speaker and my Pc with the MMSSTV Software and of course my Yaesu FT-847 :-)

My Method of using SSTV is not the Norm!
You would normaly have an Interface between the Radio and the PC, Not using a Pc mic on top of the Radio speaker as I did :-)  less

Rug placement most probably is one of the factors that you might want to consider first in selecting a rug. It is important to know where the rug is going to be placed.
