Yaesu FRG 7700, 70 cm active antenna and Dual Core Pentium 2.7 GHz
A 276 minutes long log. The decoding problems in the beginning was caused by the PC I use for programming. Its power supply is extremely noisy and even though I have fitted the FRG-7700 with a shielded noise filter on the AC socket, some seeps through. Otherwise perfect decoding. About 97% decoded audio and an average of 29.6 dB SNR from 1920 UTC.
