Thanks to Ivan OM0AM and Michal OM8ASK it is APRS Digi on Kojšová Hola equipped with a new antenna, which should better withstand frost. Today (20.12.2012) Ivan also did audibility tests and at my home in KN09OB (OM0TM, Veľký Šariš) the audibility is at the level of 59+40dB for a vertical antenna of length 5/8 lambda.
I am asking everyone to try, you can send income reports to reports@aprs.sk, put your brand in the report, QTH, locator, altitude and antenna used.
Thanks in advance for all the reports.
