Did you ever hear some strange signals on 14230 kHz and wondered what that could be? Could be that you heard a SSTV (Slow Scan Television) signal. If you have a computer with a souncard there is now a way to become qrv in SSTV at almost no cost.

There is a good freeware programm called MMSSTV by JE3HHT, Makoto (Mako) Mori, available.


This program is for transmitting and receiving SSTV using a PC soundcard. I (JE3HHT) was making a utility to adjust the soundcard clock for PSK31 programs. However, I have changed my mind, and the utility has eventually become an SSTV program.

I thought that I should have made at least one SSTV QSO with this MMSSTV and then declared it as the release version 1.0. However, I am very busy on my own business and will have no time for amateur radio. In addition, there seem to be some people already using this program. At this time, I have decided to release this version as 1.00.

Uninstall MMSSTV

MMSSTV does not add anything to the Windows registry.

Delete the entire directory where MMSSTV is installed.
