Jim, K8ELR, has really gotten into operating the digital modes down at the museum. So, I was interested to see a notice on the HamRadioHelpGroup mailing list that the KB7TBT SSTV Web Page was back online. On this page, James, KB7TBT displays a number of live feeds.

KB7TBT SSTV CQ ScreenDon, KB9UMT, the list moderator, asked if someone could explain SSTV and how to operate it. James replied:

Q. Can someone just listen in or receive only for SSTV?
A. Anyone can receive, just like any radio receiving it does not require a
license. Install the software and place your computer microphone against the receiver speaker, it’s that easy!

Q. What frequencies are there or where does one listen on HF for this SSTV activity?
A. The most popular is 14.230 MHz during daylight hours (due to

Q. Can this also be used on VHF/UHF?
A. YES! 145.500 simplex is a popular VHF frequency for SSTV. (I have even used
a 2M FM Repeater a few times). The ISS has SSTV on board and the downlink freq is 145.800 when in use. UHF is used as well but I am not familiar with the freq.’s.

Q. Can SSTV be used anywhere or is ther rules on this…and or band plans?
A. Analogue SSTV is classified as an IMAGE MODE. Voice and Image most of the
time go together. (Check your local band plans and rules.) There is some difference in opinion but analogue SSTV is NOT a digital mode. (I personally disagree)

Q. Is this a SSB mode always or can this be used FM also?
A. FM and SSB can be used, just remember to operate within your local band

Q. What software is there for this..or are there different kinds of SSTV?
A. Ham Radio Deluxe offers a fantastic program for SSTV and it is free. (HRD
Digital Master 780 – This is what I use.) There is also MM-SSTV, a bit outdated but still works well and is free. (Not sure how well it works on Win7 or Vista)

Q. Are there other online SSTV web pages to watch SSTV?
A. Why would you want to watch any other page but mine? ok, ok, there are many websites around the world. To see pictures from around the world go to my SSTV page and scroll down. All the thumbnails have links to the websites they come from.

Q. Can you DX using SSTV?
A. YES! I send and receive pictures from all over the world.

Q. Are there SSTV nets?
A. Yes, just do a search for SSTV Nets. One website I have found lists both analog SSTV nets and digital SSTV nets.
