Also make sure BOTH radios are in the same mode.
There are 2 types of data transmissions: Slow mode, as supported by most D-Star radios, and DV Fast Data as supported by IC9700 and 705...
I ran into this using a IC7100 with an IC9700, whara the 7100 ony supported slow mode and the 9700 being set by default for fast data..

Troubleshooting D-Rats:

Two computers running d-rats can have a NULL modem cable connected between them instead of connecting d-rats to a radio.

If you have only USB to radio cables, that will be harder to rig up but may still possible, but would take wiring up some jacks to cross the data lines depending on what the data port on the radio now looks like.

USB Driver updates on Microsoft Windows can stop USB adapters from working.

Since you report that the you are getting some communications, that indicates it is probably not a USB adapter issue.

Baud-rate, and character size, parity and stop bits should be checked, but I also do not think that is the issue.

Character size should be 8 bits, parity should be none, and stop bits should be one. Baud rate depends on the radio.

You can turn on the "sniff" and "raw" settings for a radio port to get more information about what is being received.

I am still trying to get a flow chart of the d-rats protocols. There appear to be some conditions where communications can just be silently dropped by one d-rats program, causing the remote program to hang.
Having two stations with the same call and ID connected to each other seems to be one of the ways to cause that condition.

While the URL for the map tile server may appear to be correct, there may be issues with the upstream server. There have been some alternate servers that are available that have been mentioned on this list.

Try instead, as it seems to work better.
Or try https//tile.thunderforest.com/cycle which needs you to setup a free account and get an API key.

Also be aware:
* Support for python3 on Microsoft Windows 7 is deprecated as of 2022. At some point in 2022 or later new installations of python3 on Windows 7 will not be available or upgrades may fail.
* Python 3.7 is the lowest version of python now supported.
* Support for python3 on 32 bit Microsoft Windows is already gone.
* Support for python2 is already gone.
* Support for gtk2 which d-rats depends on is gone.
* Support for libxml which d-rats depends on is gone.
* The geopy (address to lat/lon lookup) built into the python2 d-rats is coded for a yahoo service that has been shutdown, and is too old to support the free services that I could find that are still working.
* The format and some URLs for external data for weather, buoys, etc, have changed, and python2 d-rats does not appear to have the fixes.
* D-rats does not care about the SSID (The -x appended to the callsign).
Some types of radio connections restrict it to a single digit number.
* File transfers do not work between all d-rats systems before v0.3.10b2.dev300. There is a bug in the code and protocol that prevents big-endian (Sparc/PowerPC/etc) and X86/arm based systems from interchanging files and forms. Big Endian systems must be at v0.3.10.b2.dev300, my experimental port to interchange files with X86/arm based systems.
The protocol bug has not been fixed, just the big-endian systems are now coded to have the same bug so that they will interoperate with the majority of the d-rats systems out there.
* Map display has been completely re-written for python3, and the plotting of stations should now be accurate at all zoom levels.

The serial connector from Icom for my radio is missing some very strongly recommended optional internal jumpers. Python2 d-rats does not pay attention to the signals or have any way to diagnose that condition. In the future the python3 version will allow testing for that in the radio configuration dialog for radios and TNCs.

If those jumpers were present, d-rats could be enhanced to detect if the serial connector had become disconnected.

73, and good luck.

Yes..... Same RF freq. and within RF range of each other and you are good to go.--

That may not be entirely correct, we are a group of 15 have used D_RATS since the original version 0..3.3? via ratflector and via radio. Due to some issues with Comcast we have taken down our ratflector, and are now using D-RATS strictly on RF, we went through versions daily build 2012 and 2014 with no problems, D-RATS was always there and reliable both Inet and RF.
We are now using 0.3.9 exclusively (no beta) and seeing receive issues that we have never experienced before, we have tried both repeater and simplex with the same results on both.
Receive is intermittent at best for some stations, some not at all, and others no issue whatsoever.? One station has tried 2 radios, 2 WIN 7 computers, and different USB ports and cables, he receives some but not all stations, simplex or repeater.
Other stations just receive intermittently, also through the repeater and simplex, 2 stations regularly copy all transmissions and pings.
We have run connectivity tests from an operating station to the defective stations and get no results, yet all of these stations did work well previously. The stations that do not receive messages do not see all of the stations on air in their station list as you would expect. A ping from a defective station yields a report that station* replied to the ping but it does not always show up in the station list.
We have run tests and nets and have yet to find a reason for the reception issues, the defective stations do transmit fine.?
We have come to the conclusion that there is something amiss in the reception of the station id that does not allow the station to acknowledge the sending station.??

One other issue that we have just seen crop up is the maptiles are not loading on a win 11 machine, we have verified the tile address to be correct.?

Hello All,

Current status is that I think that most of the existing bugs in the port may also be in the older d-rats as well, but that may be wishful thinking.

I have a PR out for review that when landed converts it to use a new packaging procedure.



WARNING: Do not assume any past install procedures or kitting
procedures will work after this patch is landed or when testing this patch. Python has deprecated them for new projects.

DO NOT RUN THE setup.py script!

You must read the README.md file supplied with the patch if you want things to work.

A lot of stuff has changed.

The "python -m build" when used as directed will create a PIP instalable tarball good for only the platform it was run on.

The method of producing a self installing EXE file with an embedded python does not appear to be supported anywhere that I can find,
So support for that is dropped until I can find out how to implement it.

I have some feedback from Rod, KA5MYE for Mac deployment on Anaconda Python which I plan to incorporate in my local WIKI and into the README.md file.

Feedback for running from a git checkout source or running the python -m build command and then installing it for multiple platforms is needed.

Next I am going to start focusing on getting some github actions working including doing pylint and spelling checks, and maybe some other automatic testing.

We also only have English and Italian message catalog sources so we need help in that area as per:

.

Have fun and 73,

Trying to go P2P - not involving the internet at all. Is this possible with D-RATS?

开云体育

From Ron?

Trying that - didn't seem to help.? The program announces when run it, and announces when I exit it, meaning it's trying to tell the other program that there is someone there and then when leaving.? But I just can't get them to see each other...

Hi this is Ron WB3ILX,

So I have my 705 and my 9700 connected to D-RATS via 2 different computers via USB.? I am trying to get one station to show up in the other computer - but no matter what I do it won't show up. If I right click and select ping all stations, both stations will send out a ping over the radio with no issues.? However it's like the received signal is not registering with D-RATS. I also send a chat message and both send no issues, but neither will show up in the stations box.? What am I doing wrong?

Replace probably with will ask.

I would keep in mind that a hand held it probably not going to be putting out the power you expect. More like about 3 watts. If there is a fair amount of transmit time, the radio will probably over heat.

Why would it? ". . . occupies the entire repeater right?". I think before you get any more carried away with all of this ". . . owner so they will probably let me use it." you need to be sure. If someone was just planning to use my repeater for something like this without asking FIRST, the answer will probably be "NO" and stay that way. Most of us with repeaters have put a lot of time and expense into the repeater, not counting getting the site. Put your cart behind the horse.

I have ebay set to alert me.? ?Seems many want to sell their used ones for $325+ which seems crazy.? I'll find some sub $200.? Also found battery eliminators for $20-$29 so that will be nice when buying used.

My plan is to take a plastic cutting board and mount a radio, battery, maybe even extend the interface cable so the port on the radio doesn't break, easy 2" telescopic pole from harbor freight, UHF Yagi, and some coax.? ?Deploy in minutes and have a full D-Rats network setup in 1-2 hours in just about any terrain.

There is also a d-star B module repeater in my area.? ?I haven't done that part yet and I think D-Rats occupies the entire repeater right?? I know the owner so they will probably let me use it.? If you have advice on that please let me know thanks.

Used market …

I'll be running drats to the radios.? ?Im just curious which Icom radios are recommended and/or if there is a model I can snag in the $200 range.? The newer dual bands I've looked at are $500 and it starts to get pricey when trying to build a network.

开云体育

Dual band, Nick; at least.

Can I get your thoughts on recommended radios?? I'm contemplating purchasing 5 UHF radios, connecting some Linux or Windows laptops, and placing them at aid stations.
