Ham Radio software that I use:

	Hellschreiber (freeware by IZ8BLY, works with PC soundcard) FTPGetter (to upload receiver-screenshots to my website ; shareware)
	MMSSTV (SSTV = Slow Scan Television; freeware by JE3HHT, works with PC soundcard) Click here for sample SSTV pictures of my QSO's etc. KE5RS FTP Widget (to upload received SSTV pictures to my website; freeware)
	MMTTY (RTTY = Radio Teletype "telex"; freeware by JE3HHT, works with PC soundcard))
	MixW (excellent multi-mode for $50 (worth it!), works with PC soundcard; does not support MFSK8 mode - see Stream below)
	Stream (MFSK8 and MFSK16 modes; freeware by IZ8BLY)
	JVComm32 (I use it for HF-FAX/WEFAX, but it also does RTTY, SYNOP, NAVTEX, SSTV; free full-function demo version by DK8JV)
	Digital Modes 780 (DM780) and Ham Radio Deluxe (HRD) (DM780 is multi-mode decoder software with built-in SSTV image upload via ftp. HRD is a control program fro CAT-able transceivers. DM780 and HRD can be used stand-alone, or be linked. Both are freeware by Simon, HB9DRV)
	Click here for a write-up by GØHWC on how to calibrate the TX/RX clock settings of most of the above software packages.
	QuickMix  (to save/restore my specific PC's soundcard settings for each of my ham radio programs; freeware)
	VOA-Prop (propagation forecasting freeware) to accurately show HF beacon activity, make sure to turn on auto sync of your PC clock to the NIST atomic clock (may require turning java off, and configure firewall; double-click on time/date at lower right hand corner of windows desktop screen, select "internet time" tab and activate)
	Beaconsee (HF beacon propagation conditions monitoring; freeware)
