Thanks for info. I have a lot of fun receiving the station SSTV on a scanner and Chris' CQ SSTV app on my iPhone. The neighbors are always amazed.

Np

To decode SSTV signals, I normally connect my radio to a Windows Surface Tablet by an audio cord.  If don't know when a signal is coming (shortwave stuff) I just leave the MMSTV app running and it automatically decodes the signal and saves pictures in its directory.  If I know within a reasonable time that a signal is coming, (Like when tracking the ISS) I just leave audacity running and record the signal.  I can then clean up with signal a bit before running MMSTV.

For when I go outside to get a better signal, I'd like to directly connect the radio to my iPhone (7 with the lightning port) with an audio cord, but don't know what kind of cord to buy.  Do you use thsi kind of setup, or just play the audio into the iPhone's external microphone?

I just play the audio from the scanner into the iPhone mic.
I also leave the FT-857 connected to the computer with audio cord directly to the computer running MMSSTV. The 857 uses a dual band J-Pole anntenns (2 m & 70 cm)

Update: No transmission on the 1900Z pass over the Caribbean. Waiting on 2030Z pass over the south and east of the US.

Thanks Chris. I was just getting ready to post that nothing on the pass that is happening right now.
Do you have a recommendation for sstv on a MacBook Pro. As mentioned above, I have your app on my iPhone. I was looking at this:

I may be biased, but I recommend MultiMode Cocoa :)  https://www.blackcatsystems.com/software/cw-rtty-sstv-fax-psk31-packet-decoding-software.html

Forgot you did a multimode program for the Mac.
Anyhoo, got up from afternoon nap and had received this during the 1 pm EST pass at 14 deg east. Ground track from Panama across Haiti and ending in the N Atlantic E of Bermuda.
Next pass over SE US in about 15 minutes.
