how about doing daily screen grabs, then paste them together as layers in a graphic package.

All receiver range plotting on VRS done using Franklin 4-element antenna with matching stub, shown below.

Later Addition: I am also using an in-Line amplifier (RCA D903, Gain 13-18 dB, Freq Range:950-2050 MHz, Max Output 110dBµV, Power pass DC 14-18V 25-40mA)Last edited by abcd567; 2014-05-18, 14:40.

After last computer repairs, she issued a Presidential decree that if computer is found running without anybody using it, it will be immediately shutdown. "using" means someone physically sitting in front of computer and playing with mouse/keyboard. Unattended Data feeding & range plotting do no fall under her definition of "using".
That way she need never know that it is on, they use very little electricity and are happy running 24/7.
Also you could point out to her that frequent switching on and off of electronic devices will generally cause them to fail far sooner than leaving them on as the switch-on surge stresses components far more than anything else.

I am using a Raspberry for glider tracking, but expecting one to do all the decoding AND plotting is probably not within its capability (however I would be delighted to be proved wrong!)
Second hand Mac minis or re-furbished previous generation units are quite reasonable, just ensure it has a Core-2 Duo or better processor.
