The SSTV mode used is PD120, developed by Paul Turner, G4IJE and Don Rotier, K0HEO (SK) and is described in Classic SSTV.The mode is supported by MMSSTV version 1.13A, but it does not appear in the main mode menu; however if MMSSTV is set in Auto, it recognizes PD120 signals right away, even without an FSKID.

Today I received three images, using my Icom IC-7100 tranceiver and a simple vertical antenna. I use standard FM in the widest bandwidth (FIL1, approximately 15 kHz) without any compensation for Doppler effect. Some image degradation is apparent in the first two image, which is caused by local intermodulation effects.
For ISS tracking I use Gpredict (GNU predict) v2.2.1 on a Linux Mint computer.
