At times I operate a Simplex SSTV Repeater on 28.680 mhz USB. To access my repeater, transmit a 1500 hertz tone for approximately 3 seconds, unkey, listen for a CW response, and then transmit your picture. Whatever you transmit shortly after the CW response to your 1500 hz tone will be retransmitted on the same mode. There are other SSTV Simplex Repeaters on 28.680 that respond to other tones. This can be a neat way to check the quality of propagation, check your slant, check your signal quality, test various SSTV modes, etc. My Simplex SSTV Repeater is not currently on 24/7/365. I do hope do make it so in the future. Additionally, I am planning a Simplex SSTV Repeater on 145.50 mhz FM to serve the Greater Louisville/Radcliff, Kentucky Area. I may conceivably link 145.50 to 28.680, thus allowing local and distant stations to exchange pics. With the current state of ten meters and the loss of several rigs due to lightning, my time on 28.680 mhz will be limited for the time being. Check the band banner on the top of this page for my current band of operation. K7EK Simplex SSTV Repeater will transmit a beacon picture every twenty minutes when active. Enjoy!
