I have the Black Cat Systems "SSTV for iOS" app on my iPod Touch
and several iPads. It sorta works, but leaves a lot to be
desired. It can grab an image direct from the camera, or use any
existing pic on the device's "Camera Roll". Despite using the
"iGadget"s rather high resolution camera, it only does the
traditional 320x240 pixel modes. It won't do the higher-res 640x480
or 800x600 modes which is a shame, given the image quality of the
camera. It won't do the MPnn-N 500-Hz-bandwidth narrow-band
modes that are the only SSTV modes legal on 30 meters. It lacks
the image editing/cropping/extensive text overlays that Windows SSTV
applications such as mmSSTV and Chromapix have. (You can type a
single line of text at the top of the screen.) <br>
<br>
Perversely, for an app transmitting exclusively landscape images, it
runs only in the portrait orientation on iPods and iPhones, no
matter how you hold the device. This makes the view of the image
being received (or being previewed/titled on TX) needlessly small.
(On iPads, it will run in the landscape mode.) <br>
<br>
I use the app through a tiny home-brew interface that is a modified
version of the KH6TY self-powered tone-activated interface into
either my TH-D72 or a Wouxun KG-UV-8D. (Both have the identical
Kenwood-standard speaker/mic pinout.) I velcro the small
interface to the back of the iPod or iPad, with a 3-foot cable
running to the hand-held's speaker/mic connector. <br>
<br>
By the way, about three weeks ago, I actually successfully sent and
received live SSTV images from my TH-D72/iPod on 20 meters using the
Kenwood TS-2000's "Sky Command" remote-control feature.<br>
