Great summary. For handheld security I like license the free 900mhz band and the obsolete Motorola DTR 450/550/650 radios with FHSS “frequency hopping spread spectrum”. With public and private channels available and FPP ‘front panel programming’ with some models over 33 channels and several more bands and groups. Even with that exact radio no one can eavesdrop on direct radio to radio comms without your ID, channels and group memberships. Even then you’d hear them break squelch…
Not saying it can't be done. Just saying that 99% of those listening will not have the capacity to decode. Thanks for the info though!! I was aware of that.
Yes but in most EmmComm it will all be done on VHF/UHF, direct or via a repeater /Reflector that still works D-Star HF isn''t reliable and is VERY dependant on signal levels and propogation. Bedroom tests are not real
@@3TQVK you are missing his point....no BUTs about it. If it is possible (independent of band conditions) and does not rely on internet then it is game!
@@d.s.mcclure9584 No I am not You don't see the point either, D-Star is not secure it was never designed to be. No butts about it and again bedroom tests are crap, been there done it , tested it, tested it with D-Rats, ex Icom senior manager, but I guess I'm STILL wrong . I never said anything about internet , like it or not the DNA of HF are band conditions. The only thing that is secure is a digital signal with AES 256K encryption with a key that changes daily, like our police force have using mototurbo AES If you think that any mode is safe without at least inversion or 128 or 256 encryption your in fairy land. I will leave you with one comment Yeasu, Kenwood and Icom ham radios, appear in third world countries. All the time Because there allocations ie 144 Mhz may not be Amateur. They are not secure !! They weren't designed to be. Our military and your military are all over it Have a nice day
Hi Bob, Thanks for sharing. I never thought about the possible use of ham radio for sensitive patient data in emergency situations. Unfortunately sensitive patient records are protected by HIPAA privacy. Only those with direct need to know would be expected to have access to HIPAA protected patient records and demographics. From my understanding, even D-Star would not meet the privacy standards in almost all cases. But now I'm really curious how privacy could be met in these situations. The benefit would seem to outweigh the privacy standards. I think this is really something to think about and petition the FCC on. ( allowing some type of encryption )
Talking about moving or discussing medical records using ham radio doesn’t make sense because it’s in violation of HIPA laws. Patient info has to be secure, and since encryption on ham radio is not allowed its a non starter. If you want to talk about secure voice communications for ham radio again encryption is not allowed. If we want to discuss discreet comms using ham radio then that’s fine. There are many legal ways of doing that, D-Star, C4FM, other digital text modes are all great since only hams with those radios would here it and in simplex operations not repeaters odds are no one would be listening. Another way would be simplex on 220 or 440 radios, it would be difficult to catch conversations on some random freq especially if comms are short in duration. Any sort of published repeater system would not be wise in any form for discreet comms. One of best would be simplex D-star or c4fm (Yaesu) somewhere on the 70cm band as an example.
Bob Ross Hi... I was thinking of that one too, I couldn’t think of which radio it was... yes thats a great one that no one could hear except your group using them locally. Only problem is you would need at least 2 of them and they were discontinued this month and are now gone from all the suppliers already including ebay. I would have picked one up if I knew they were discontinued ... arrggh. I like 220 and have the DR-235T mkIII
Bob, really, what about FT-991 C4FM on HF. Agree with Pierre, drawing a long bow with a short arrow and to be quite honest D-Star on HF is tedious at best, worked on 40 6, and 10m and contacts are hard work. Your test is "Embryonic"' in a control situation. On 40m it will be very different and the received signal MUST be at least Read 5 /Strength 8 or higher for it to work. I have 2 7100s and work HF Digital when I can. I have lots of experience with D-Star and have been using it since 2006 I am Ex - Icom. Can I suggest you take a look at CODEC 2 Narrow band digital for HF Thats really inspiring'. I think its more reliable than D-Star HF. I participate in a 700Km hook up on 40m Most Sundays, Sounds great We meet on 7117 9:30am Australian Eastern Summer Time I can email you a video if you would like to see it. PS There are no manufactured radios you can switch on to receive this, its all via modem to any HF radio....but its voice only at this stage....I think.. Full Digital Voice at 3KHz bandwidth Really amazing and I would say definately more "secure" than D-Star in an EMCOMM situation Look up Rowetel SM1000 73's Pete VK3TQ / VK2LD
Peter Willmott Can't listen to D* on a 991. C4FM is too wide to be used on any band but 10 meters. Was not so much referring to DX on HF but rather local emergency coms and regional at times but mostly local. I Googled the SM 1000 and all links to it appear to be dead. Watched a few vids and it is an interesting concept but HF DV has been around for some time and the software is readily available for free download to monitor that mode. Too bad the SM 1000 is no longer available. Would have been fun to play with. Thank you for your informative input. 73 de N7RBP

Great Plan!!
guys you can decipher dstar on hf with a simple sound card and dsd+ software...

Thanks ..interesting points Bob. Mike WG7D
What about the AOR AR-DV1 wideband scanner? It can receive D-star transmissions and it covers down to 100 kHz...
smart arse

Actually, the MOST secure mode at this time is D-Star on the 220 band. Only one radio does that....the Kenwood D-74
