Looks cool. I'll try playing with it tonight. |

This guy has a bunch of paid apps for android. |

One of the things that always kept me from trying SSTV is all the sub-modes:
Robot Modes: 36 & 72 Martin Modes: 1 & 2 Scottie Modes: 1, 2 & DX Wrasse Modes: SC2 180 I guess I could get off my lazy ass and Google it, but.......................... A couple times I downloaded some software to work SSTV just because I came across it and I started to play with it. I never knew which one of these modes were commonly used and before I figured it out, I got sidetracked onto something else that caught my eye. I used to have a guy in Mexico who needed Nevada for WAS on SSTV and he became so annoying about it, that, that alone kept me from getting on there: He pissed me off. I was interested in other things and I didn't want to take the time to figure out SSTV. I meant to, but never did. I should post a disclaimer: I felt bad about it. I have chased awards too and I have been in his shoes. When I moved away from Nevada, I needed ONE state for WAS on JT65 and I pestered a guy in North Dakota about it and never did get ND on JT65. But I also have to add that I emailed him a couple times and that was it. I didn't keep it up. I figured he was either going to help me out or not because I was concerned about getting the same reaction. I know that if you are an asshole that some guys (DX in particular) might "forget" to put you in the log. |

I have some of his (Wolphi) apps. SSTV, RTTY and PSK Droid. so far so good as far as receiving, haven't transmitted with them yet. ETA - ElectroDroid is worthy of downloading too. It's a free app that has resistor color codes, IC pinouts, cap values etc in it. PSK Droid is good. I use it when operating portable. Works quite well. |

I decoded my first SSTV signal with my phone over the weekend in the contest. Would love to try sending if anyone wants to give it a try.
I've never had an SSTV QSO of any kind so I don't really know the protocol. Do people use voice to coordinate or do you just start calling CQ on 14.230 with SSTV? |

I also have never had a SSTV QSO but I would like to try. It may not be for a couple days though. Yes, they are on SSB and occasionally send a picture. |
Help a noob out who only has his Tech, and Baofeng HT and one of those DTV USB stick SDR's and a "Ham It Up" converter. 
Once I've gotten the app off the Play Store, what would be the way you'd get the received SSTV transmissions into your phone without going completely broke? |

Will try to hook up this afternoon!
|
If we schedule something, I'm good to run out to the car for a couple minutes for the rest of the workday.
For some reason I've got noise on 17 and 20m again when the engine is running, so I can't really bear sitting in the car for more than about 10 minutes at a time w/o heat, lol. If I go out in the next 30 minutes or so, the engine will still be warm, so there's a plus. |

If anyone is listening on 14.230, I'm about to try to send something... Let's see if it works. 
I'll send at 1435 eastern. Great...now I'm here early. Will definitely try to hook up in a bit. I managed to successfully decode an image why just holding the phone up to the radio. Will see if I can post it. ETA: 
|
I successfully sent something at 1435 and 1437. Then I received something, but I wasn't fast enough getting the receive application opened up... 
ETA: aaaaaaaaaaaaaaaaaaaaaaaaaaaand the app didn't save it. :( I actually saw my name in the image, so I knew it was someone sending me something. ETA2: And I learned that my car's setup will actually transmit at 100W for quite a while without catching on fire. ETA3: Oh, it wasn't directed at me. That's kinda crazy, lol.

Once I've gotten the app off the Play Store, what would be the way you'd get the received SSTV transmissions into your phone without going completely broke? All these digital modes are just audio. You can get it into your phone simply by feeding the audio into the microphone and out the speaker. You can and probably should use a cable, but you don't have to. We do digital modes all the time in our local ARES group just by holding an HT up to the built in mic/speaker on our laptops. You could also use Bluetooth for receiving. I have a little Bluetooth device you plug into the speaker jack on something (a radio or whatever) and it gives you the audio in a bluetooth headset or other bluetooth device. I also have a Rig Blaster Blue that I can do either SSB or digital modes via Bluetooth. But I guess maybe the software app would need to support Bluetooth so maybe I am just talking to myself

I do and it works fine, just place phone close to speaker to drown out any background noises. ETA - We need to have an SSTV net. <--someone who hasn't checked into the digital net in months..

Ok, I will be listening. Or watching. Wait, there is activity on there right now. You can try to work. K0TAZ Quoted:

Ha! Sorry I missed that one! 14.230? Ok, I will be listening. Or watching. Wait, there is activity on there right now. You can try to work. K0TAZ Frequency in use here...alternate? |

Hold on just a second...looking for something clear. I have what sounds like a round table on 170 here. ETA: how about 7.175? Quoted:

7.171 That would be better for us anyway. We are probably too close for 20 meters. Hold on just a second...looking for something clear. I have what sounds like a round table on 170 here. ETA: how about 7.175? Ok, whatever. I don't hear anything on 7.170 but if you do, we don't want to use it. |
|
Ok, I got a lot of SSB traffic at like 7.176 or 77 with lots of bleed over.
The signal I was copying was lower, like maybe 7.172 I would think that 40 meters would be ideal for us at this time of the day. I don't know where in WV you are, but I am right on the WV border. The Northern Panhandle, near Weirton. By the way, is that your dag ? That cracks me up every time I see it. |

That's what I wasn't getting. I was worried you all had Elecrafts with some sort of USB port and it would transfer data to phones or tablets for decoding. So I should be able to do this with a little luck a DTV USB dongle, and my upconverter, and I just need an audio-out-to-in headphone jack from the PC to my phone, or obviously just run a SSTV decoder app right from SDR# or whatever on the PC itself. Thanks. I just had a mental gap in the process and needed it filled in.

When I first starting playing with digital modes, this was something that I didn't get immediately. It's just audio. If you are using a dongle, you can just hold the phone up to your computer speakers just to make it work. And, as you say, you can run a cord from the output of your sound card to the phone's microphone input. It's been awhile since I played with one of those dongles, but do they have a setting in there (the software) as to where the audio output goes to ? In other words, does it have a setting that you tell the software to send the output audio to your speakers ? If it does, you could use a virtual audio cable to port the audio to SSTV software like MMSSTV and not use the phone ? |

Another thing to bear in mind is most digital is, I believe, worked on the upper side band regardless of whether the standard for voice is USB or LSB for the given band. |

I'll have to go home and play with it tonight, but I think SDR# actually has a plugin that will do direct SSTV decoding, right from whatever you save on the PC. |
