Digital Modes / Re: A kind of WhatApp for HF
Last post by DL1DBY - June 13, 2020, 08:14:06 am
I had the same issue that I couldn't find the HF Pager app by searching insider the Play Store app.

In his newest video RA3TLB shows a short sequence where he uses the HF pager app with an FT-817 during a backcountry hiking trip at time frame 8:35 minutes of the video. There is a cable attached to his smartphone, but it is most likely a powerbank, as it is not connected to the headphone jack of the phone. There is a nice old full-metal soviet microphone next to FT-817 and the smartphone. So the chance is good he is simply using micro/speaker with the app and not a complicated setup with a dedicated interface:

Too bad my kowledge of Russian is not good enough to contact him on his vKontakte group. I don't think he speaks English as he shows only QSO in Russian in his videos. I asked him in the comment section of the video about the app. I used Google Translate.  I am waiting for an answer.

I can't find it in Google Play. What does the logo look like? Do you have a link?

Thanks,

Yes he is ;-)

Definitely, that is an interesting subject. I have only looked at the TYT MD-680, great handheld for prepping groups. The one-time-pad is a great, albeit slow option with Morse code; I have made a video on that..

I found that you made a video with that theme, too:

Thank you for the first two videos shown previously! -- Here are their YouTube URLs, too:

Maybe we could try on 40m from F to DL (Frankfurt region). I have an Elecraft K2 with no digital connection box so far so I would have to use microphone/speaker. I can only operate HF portable in the field with end-fed antennas and 1o Watts. Though QRP from portable to portable might be challenging ond require good condx.

Videos about Syria in which Hytera handhelds can be clearly seen are in the Youtube channels of ANNA News, which has journalists embedded in Syrian army units and in R&U Videos, which produces English language captions for some of ANNA News Videos.

Of course these channels are not neutral, there are on one side of the conflict, but that is certainly not the topic of this board.

Concerning the Venezuela I haven't found those articles again as Google does not promote them, but they had a photograph of Venezuelan officers sitting in a hangar at a table with DM-1801/GD-77 in a protective pouch and the article did quote Venezuelan government sources saying use of Motorola XPR3500 by the invaders would indicate CIA connection.

A friend of mine has a Motorola DMR handheld. So is he CIA too?  ;-)

In a crisis situation I would use encryption too, but so far I haven't experimented with encryption. Would be interesting to know if the different radio brands  are still compatible with encryption.

Thanks, interesting if just for the added privacy. I will have a look!
