D-Rats via RF - Experience - Capabilities - Usage

Edfel Rivera All Messages By This Member #2714 Hi: Looking for feedback about D-Rats RF capabilities, usage.? So far have been testing the repeater - client from network connections. Planning to move now into the serial (RF) setup.? My radio is a ICOM IC900 Have several questions: 1- Which freqs are used for D-Rats ia RF? 2- Which speed can be expected and how such speed compares with Packet, VARA FM.?? 3-? It is possible to run D-Rats via HF or low bands? Sorry if any of those questions are basic or simple. 73 Edfel KP4AJ
Jack Spitznagel (KD4IZ) All Messages By This Member #2715 开云体育 Hi Edfel, ? I have a “partial” answer for you. I don’t think there is an “easy” way to use the IC-900. ? D-RATS uses the D-Star data modes (among others). If you have any of the D-Star radios (plus a D-Star repeater) around, then there is a “slow” data channel along with the voice channel it is quite slow, but works for Chat. The 1.2GHz radio can be all digital and has reasonably fast speed – don’t remember exactly (maybe 4.8kbps in DV, ?128 kbps in DD mode???). DD mode is 1.2GHz only, available with the IC-9700 and the old ID-1 +/- the DD module for the 1.2GHz repeaters. ? We have used a local D-Star repeater (W3DHS) for ACS/ARES/RACES exercises. You can use D-STAR simplex as well. There are suggested DV simplex frequencies for 144 and 440 MHz – check the dstarinfo.com website. ? I use 9600bd for the connection to both the IC-9700 and the IC-705. I configure to the appropriate COM port. It works for me. I usually use the internet mode so the radios do not stay on. ?

Edfel Rivera All Messages By This Member #2717 Hi Jack: Thank you very much!? For EMCOMM, D-Rats RF capabilities and performance are key.? ?Hope to be able to test that soon. 73' Edfell KP4AJ
Al Massaro KF5SMH All Messages By This Member #2719 Edfel, one thing to watch out for when using RF, ID 5100's send Hi speed data, ID 880, ID 2820, ID 51 all use low speed, make certain to reset the 5100 to low speed if you are trying to send to one of these. MENU>DV SET>DV FAST DATA >FAST DATA>OFF. -- AL M KF5SMH
Edfel Rivera All Messages By This Member #2720 Hi AL: I have a IC9700, but I guess is the same. I have to setup low speed.?? 73' Edfel KP4AJ
Edfel Rivera All Messages By This Member #2721 Edited Hi: Just to be sure. I have set the 9700 and seems to be working.? As D-Rats states there is no longer a need for a D-Star radio, the question is which other 2M 70cm radios supports (or can be used) with D-Rats for packet communication??So I might coordinate with a fellow Hams at my county and test maybe in simplex 145.610, 145.670. The idea is not to depend on D-Star repeaters although anyway here there are nada D-Star repeaters.?? One of D-Rats KEY, and somehow rare, advantages is Interoperability (possibility of EMCOMM traffic via both RF + Network).?? Thanks again!! Edfel KP4AJ
Maurizio Andreotti IZ2LXI All Messages By This Member #2722 Hi Edfel I personally never used d-rats with radios without d-star support. Anyhow D-Rats was added with kiss support in the past: Not sure if anybody had a chance to?test it with recent versions. would be interesting to have more info and report on experiences on?this. thanks maurizio toggle quoted message Show quoted text Il giorno sab 16 set 2023 alle ore 08:32 Edfel Rivera <edfeljose@...> ha scritto: [Edited Message Follows] Hi: Just to be sure.

Edfel Rivera All Messages By This Member #2723 Hi Maurizio: Thank you very much!? ?There are many D-Star capable radios out there but if D--Rats supports also other brands through TNC / modem it increase D-Rats possibilities!? It could be very useful if someone can test and document such connectivity via RF.? ?I supposed if there is a pdf document describing someone should have tested, I hope.? 73'' Edfel KP4AJ
Edfel Rivera All Messages By This Member #2724 Hi: Well wonder if this could make it happen:???I have and old SignaLink also but not think have the cable and mod for my Kenwood TM-v71. Probably best and simplest way to test is with a Baofend.? ?Hope the hardware that work with WinLink / VARA combo also will work with D-Rats via RF.? Will take sometime until I report back but guess that is the way to do. 73' Edfel KP4AJ
Edfel Rivera All Messages By This Member #2725 Edited Hi: Found also this which seems more affordable and fit for Handys.??? Deleted the link as I am not sure it will work with D-Rats.... Opinions? 73' Edfel KP4AJ
Edfel Rivera All Messages By This Member #2726 HI: Please? note the AIOC seems to don't have the TNC integrated!!???Not sure if it still should work with D-Rats, se back to step 1...From GitHub.... Future Work Overmolded enclosure design (DIY using 3D-Printed mold and Resin/Hotglue) Maybe integrate a TNC Modem with KISS interface? (I am not sure if that is worth the effort) Sorry guys! 73' Edfel KP4AJ

Steve Stroh All Messages By This Member #2728 Edfel: Apologies if this is already known and understood, but D-RATS was originally created solely to take advantage of the (slow - 900 bps) data stream built into every D-Star radio (and passthrough every D-Star repeater). Other Amateur Radio data software wasn’t designed to take advantage of “just a data stream” with no modem required and no built-in protocol; D-Star data was just data in on the transmitting D-Star radio, and data out on any D-Star radio that was receiving that transmission. The original author of D-RATS did a brilliant job making use of D-Star data when nothing else really did so. If you want to use data capabilities via radio other than the built-in D-Star data, then there are many more suitable modes such as packet radio, modems, software, etc. Just a few examples are the Dire Wolf software TNC, VARA FM (up to 25 kbps), the NinoTNC (hardware TNC) that can do 9600 bps with Forward Error Correction, Winlink software for EMCOM, XASTIR for APRS, etc. Steve Stroh N8GNJ --- Steve Stroh N8GNJ (he / him / his) Editor Zero Retries Newsletter -?

Calvin Burnham All Messages By This Member #2787 I'm trying to communicate between a 5100 and a 7100 over RF using a simplex frequency.? I was getting nothing between them until I saw your post regarding the 5100 setting.? Thanks!? Now it works one way (from the 5100 to the 7100) but nothing going from the 7100 to the 5100 (i.e., under the Chat tab).? ?I want to be able to do email, exchange files, etc via simplex but I've had no luck connecting the two.? Any thoughts??
Michael Mandell All Messages By This Member #2788 Edited I have both those radios and they can work together with data. First item as you saw is 5100 has "fast data" mode. THis does not exist on the 7100 or other older DStar radios. Just FYI, "Fast Data" is the ONLY data option on the Kenwood TH74 and TH75. "Fast Data" is OK, but it works by taking all the bandwidth including what you may have wanted for voice. It's faster but for chat it's not noticeably faster. D-Rats chat is very fast. In my experience (extensive) it's as fast as "fast packet" and FASTER than VARA chat. Yep. VARA? is error corrected and that overhead slows it down on chat. D-Rats chat is raw data---no correction--makes it really fast but can have errors.? On file transfers, well, it blows D-Rats away.? If both your radios are on slow data, make sure BOTH radios have your data mode set to "DV Data". NOT CI-V!? This is a common problem where D-Rats data does not seem to work. To use your phone app you swich to CI-V. You have to switch back for D-Rats.? Other than that, I don't know why they don't talk to each other. And D-Rats was designed for simplex. It's actually faster in simplex.? One thing to add for this thread---back before some of the updates I got the "D-Rats Repeater" to work here, so I could connect a TNC-X (yeah, hardware works fine) on an 880H to D-Rats as well as another radio using D-Rats seriall data and they bridged chat. I would transmit chat on the 880H (packet, not D-Rats) it came into D-Rats then re-transmitted out on say my 5100 as DV Data. Every connection saw everything in chat. Now I can't get it to work at all. I wonder if something broke in some of the D-Rats updates over the past few years??
