Droid Smartphones Decode RFz

[SCPD]

I am amazed how much a android smartphone can do. I purchased 3 apps on Google Play from Wolphi. DroidPSK DroidRtty and Morse decoder. Morse decoder is hit n miss and lags when agc kicks in. DroidRTTY and DroidPSK work rather well. All uses audio coupling. Worth the money.

I posted this info for those who want to do more with shortwave and their android. DroidPSK does 31 and 63. DroidRTTY does RTTY45, German DWD RTTY, but no ability for RTTY850 (encrypted anyway)

All my decoding sessions have been pleasant. The times text is unintelligible is during QSB, or signal fading. MFSK16 seems to decode under QRP conditions. There is no app on Google Play that can decode MFSK for android. I could recommend AndFlmsg (android port of FLDIGI), but it hogs battery more than my comfort zone.

I also recommend not using PC near a portable shortwave radio. Unplug a laptop especially. Android smartphones are very quiet. That helps with getting good decodes along with a good antenna.

Thanks

Interesting, unfortunately rather limited for non-ham use though. There are SO many other modes out there, and sad to say, Baudot RTTY is very nearly dead, outside of ham use (except in cases like the DWD out of Germany, as noted). There aren't many other non-ham stations using this mode regularly anymore.

Thanks for the contribution, in any case...Mike

Thanks for replying. I noticed how limited it is. I am not a licensed ham but just listening on phone qso's and reading the decodes are enjoyable for me.

As for morse decoders they are rather limited because the person sending might not be spacing letters to what the app expects ie ambigous spacing words and characters. In this case it's not the sender's fault because the receiver understands morse code well. Best to know the code. Human ears are the best decoder.

There are some decent apps out there.

I found an audio processing app in the Play Store where you can scramble and descramble using voice inversion (9 selectable inversion points).

I found some amateur (?) radio users on HF in the 3MHz range and I couldn't decode them with USB or LSB on my Kenwood R1000 but when I run the voice through the 3.333 KHz inversion setting it decodes.

Not sure who these guys are because they are cussing, etc. There conversations are general BS.
