I didn't know people were doing d-star on HF, that's pretty cool! You're right about the antennas though. I'm also enjoying the 705. I guess Yaesu won't bother with another portable radio 😂 Thanks for the video Bob.
OH8STN. Love your videos. When the band conditions were better, we used to talk from the USA to England and Europe on DSTAR HF Voice all the time. KQ4KK
The IC-705 ia an AMAZING little radio! ☺ - Especially to someone who first got on the air 56 years ago. Started hamming at 16 years old; had my Technician class license before my driver's license! It led me to a 45 - year career, starting in consumer electronics, working for a small local TV repair shop, moving into being a commercial 2-wy radio tech, then industrial controls (NC & CNC machine tools, some industrial robotics), back into 2-way radio for a few years (including doing some ham gear repair professionally), then spent my final 20 years working for a major enterprise - level data storage systems manufacturer. Went from working on late vacuum - tube era equioment uo to SMT. Now retired, I enjoy restoring vintage rigs that were "dream radios" when I was in my teens & early 20's. It's not all nostalgia, though; my early days on 6 meter AM turned me into a VHF / UHF / microwave weak - signal operator, still more active in that aspect of the hobby) up to 1296 MHz. currently, planning on going higher). I just found out about HF D-Star recently & gave it a first try last week with the IC-705; heard several signals, no 2 - way QSO's yet, but that was with the barefoot IC-705, & my HF antennas are all simplr dipoles; planning on trying it again in the near future. Maybe with a bit of luck, we'll work you! ☺ 73, Tom WA1LBK
DSTAR HF VOICE Simplex.... NO Internet, NO Repeater, NO Reflector used. Great video Bob and congrats on the coast to coast contacts. When the bands come back we will be doing England and Australia again on DSTAR HF voice.
DSTAR HF VOICE is simplex, just like most all other HF. Your DSTAR radio encrypts you, you transmit and the DSTAR radio on the other end decrypts. Like simplex on 146.52. Watch the video again. Bob does not link anywhere.
Have you purchased the IC 705? If you're familiar with this radio and care to share your opinion, I'd welcome your input. I'm a total newcomer to Ham radio and am going through a mountain of information so that I can make a wise purchase, before the end of the year. I'm looking for opinions and recommendations on what radios I should be considering, I need help narrowing it down to just a couple of good radios that will meet my needs. I'm looking for the best radio for emergency communications during a worst case scenario. I saw this IC 705 radio reviewed very favorably on another channel and it's got some nice features. But I just learned that there's an issue during a true grid-down situation between analog and digital Ham radio communications (Analog was said to be better in a bad situation - but I don't yet understand why that's the case or what that looks like in a radio's list of features.) I'm looking for a new, good quality, durable, reliable, mobile Ham radio (not mounted in my truck - something I could carry in a case and use both at home and on the road). While I could see myself possibly enjoying it as a hobby - the whole reason for this purchase is for emergency communication, so I'm not interested in paying for 'bells and whistles' that a passionate hobbyist might enjoy - I'm only interested in features that are truly meaningful in the operation of the radio such as: watts, multiple power sources, larger display screen for aging vision, durability, (made in the US if that is even possible), and quality of sound both transmitting and receiving, without having to purchase additional external equipment. I'm looking to purchase just one good quality radio - I don't wish to get a "beginner's" set up, and plan to upgrade in the future - I'd just like to make the correct choice, one time and not waste my limited funds. Thank you for any suggestions or direction to further information - there's so much info to cover!
Well I guess that's about as wide as AM, so no big deal on HF. I think, as far as communication goes, I'd prefer SSB. More intelligibility. I wonder if anyone has done a test to see how low of a signal you can get away with and still maintain unbroken audio over Dstar, vs clearly understand the voice under SSB. That might be an interesting experiment to do. (Once I get one of these. :-) However, as I understand it, dstar allows for sending additional data over the transmission. Text and images? Maybe GPS data? I'm sure there are lots of tricks up it's sleeve.
DSTAR on HF is 6.2 khz wide, about the same as AM. DSTAR on HF will never replace SSB. CW. If you have a good DSTAR HF signal it will decrypt all the normal DSTAR sent data; Callsign, name, and GPS location.
@@kenthufford743 Looking at the scope on his radio, it seemed to vary in width. Some stations were around 6khz, but his transmissions and some of the other stations were 10khz wide, going from +5 to -5 khz on the scope. That's ok though, as long as the operator is considerate and makes sure he's not encroaching on nearby qsos.
@@K6UDA Sounds good. Let me know when is good for you. The last 2 evenings 80m was pretty bad. I will check tonight around 6pm to see if it is improving, and let you know. I have a 75m dipole at 6' on my wooden fence and I have been able to get out to ID, WA, SoCal and AZ as well as Sierra Foothills.
@@K6UDA I will be on this evening at 6pm through about 8. If tonight doesn't work I am available to test just about any day (working from home). We can coordinate on 14C or if you prefer your YSF room, or email.
I cant get Dstar to work no matter what I try on my 705. In fact ive gotten to the point that I hate Dstar and its absolutely BS compared to DMR and I dont even like DMR. But as cool as this is, military already has digital over HF so ive already seen it in action, but i'd rather sideband some high power stuff. Im so over trying to get Dstar to work. Im fully registered etc.... can't use terminal mode, cant hear anything, cant do crap. But I could get DMR working in 5 literal minutes first time I ever tried it.
Hey Bob, Love to try D-Star on !0m to California, About to put up Diamond CP-610, Have worked KH6 & W6 before on SSB, so it could be a go Peter VK3TQ / VK2LD

Thanks for running the net Kent.
How does that work? It has to link to a DStar node somehow surely?!

@@kenthufford743 I use DStar on my 9700 so am just not familiar with the idea of not directing the data stream via a reflector.
@@kenthufford743 Hey Kent have we worked before on D-Star HF, Maybe ...Pete VK3TQ
Damn you Bob!!!!
First the KX3, then the TH-D74 now I have to buy an IC-705? We need to keep this a secret from my wife.

@@sheri4673 If you are new to Ham Radio, buy a 100 watt HF radio. Not a QRP radio first
@@sheri4673 Welcome to Ham Radio. The FTM400 is a good choice, meeting your criteria.
With the IC-7100 and IC-9100 you get 100W on DSTAR. A few years ago Hamnation had a short segment of DSTAR on 40m.
Awesome demo, didn't know it was possible
..
Very exciting … thank you for sharing
Oh, if only I had a 705.
WAIT! I do! I just learned of this weekly net and will try to at least listen this weekend.
Do you know if this net still exists?
@@ch716 I don't know and never did tune in ... and moved 1600 miles ...
WOW!! The voiceover is 10 times louder than the audio.
Another super video.
Got a question, what tower and antenna were you using.

hi bob , nice not to much here in new zealand have to many 705 around we will give it a go think it is great
pieter
I believe D-Star exceeds the bandwidth allowed in the US below 10 meters.
About the same bandwidth as AM.
@@kenthufford743 I believe it exceeds 6 KHz. Yea, that’s “about” the same as AM but it still exceeds the allowed bandwidth.
nice !! i wil try it to, thank u K6UDA
The 705 is a nice radio. It would be nice if a replacement for the 9100 was in the works
Are there calling frequencies on the HF bands for DStar?
Answering my own question, YES. You can spot yourself for a DStar HF QSO at: hf.dstar-relay.net/
yes, 27.025
Well I guess that's about as wide as AM, so no big deal on HF.
I think, as far as communication goes, I'd prefer SSB. More intelligibility.

However, as I understand it, dstar allows for sending additional data over the transmission. Text and images? Maybe GPS data? I'm sure there are lots of tricks up it's sleeve.
Nothing I've experienced is clearer than DStar, no QSB, QRM or anything else. Crystal clear comms.
@@johnratcliffe6438 Watch this video all the way through then. There were many stutters and audio glitches as the signal level changed.

@@loughkb Sorry Kevin, this is the first time I've seen DStar used without a Reflector. My comments were based upon my use via my 9700.
Aloha Bob! A very cool demo of D Star HF on the IC-705, almost makes me want to trade in my G90...NOT!!!😂😂😂😂😂😂😂😂😂😂😂
Hi Bob. Nice video, again. Can you tell me what the antenna was you were using please? Thanks 🙏 📻. Eamonn, G4TZV.
That was a Hex Beam Antenna. I didn’t see it long enough to see if Bob had it on a rotor but knowing Bob, I’m sure he did, I know I would! 😂
Hexbeam at 40 feet.
Almost enough in the kitty for mine, I can't wait!!!!!
So how do you set that up then? I thought you had to use a repeater?
I couldn’t said it better
Dstar hf on icom 705 sounds great 👍
Tell us how to set up radio, I have 7100,
We should try a 80m dstar qso. I am in Antioch
I say lets try.
