Re: Simple drats question
Well lets go through that.
Nobody is stopping you from using your local DSTAR repeater as long as you are using digital voice.? As far as linking, some people get upset, some don't. If there isn't much action on a repeater I wouldn't think linking would be an issue.
APRS. I LOVE APRS. And you actually CAN test it. Here's how. Download a program called Dire Wolf for APRS. You can simply place your computers microphone in front of your scanner speaker and Dire Wolf will decode the signals and display them on your PC.
Want to get fancier? Download APRSISCE/32. It's free as well. Load that up and follow Dire Wolf instructions on how to use Dire Wolf with APRSISCE. Now the data Dire Wolf hears will be displayed on a MAP ON YOUR PC. VERY cool. ALL FREE!
All instructions are withing the software and on youtube even.?

Re: Simple drats question
We have a Georgia Ratflector, gaares.ratflector.com, that can be accessed via Internet. ?We also dedicated REF030D for data (D-RATS) traffic. ?We normally have
the WD4STR C repeater in Lawrenceville dedicated for D-RATS traffic, but it is being relocated this week.? You may want to try Internet access before linking a repeater, but in all cases, it’s good to announce you intentions to relink a repeater somewhere
else as a courtesy.
?
During the SE D-STAR Weather Net on Sunday evenings at 9:00pm, we also have a D-RATS net running on the sewx.ratflector.com Ratflector.

Dear Drats list friends,
I am curious about how to practice Drats over an RF link, I live in Atlanta and we have two very active DStar repeaters, W4DOC and WX4GPB.? Is there a specific reflector or repeater where I can find drats users to casually chat or nets to check in? I could
link my local repeaters and practice some there.
Thank you,

Re: Simple drats question
Hi Keith,
I would like to add my two cents since I am new to this ham radio as hobby and to D-Star. I own my radio for about 3 weeks and the problem with D-Star is that you can not really use it.? You can not link really anything to your local repeater it will always upset someone, does not matter if this is Drats or a reflector. I have heard 2 people on D-Star last week and I am guessing that nobody is using this system from the fear of upsetting someone. At this point I use my ID 31A for FM only, since all the action is there.?
I have started to investigate APRS and it looks much more promising. There seems to be a dedicated frequency for APRS digipeaters. I have dialed my scanner to this frequency and I can hear data bursts coming here and there. Since I only own ID 31A which does not do 2m I can not test it.
What I do not get at all is the idea of setting up DVAP and using radio like a cordless phone around the house. Topic for a different story :-)?Again, I am new to this and I may be missing something, but my first impression is that the system does not work.?
Thank you!
Tom

You could set up your own Ratflector. After that you connect your DTAR radio to your ratflector via USB/Serial cable. That is what I do for our local ARES. BUT I only connect the RF link to our DSTAR repeater for drills, practice and emergencies. Other than that the DRATS Ratflector is IP only, no RF.
I wouldn't link DRATS data over over a DSTAR repeater without specific permission. It's not voice and people may get angry if like you said, these repeaters are active.
Instead if there are nets on the machines, contact the club conducting the nets and see if they would like to do a DRATS type of net after the voice net.

It was found :

Re: Exception: Not supported due to lack of license for lzhuf
Hey Mitch,
Where did you get this copy of D-Rats??? I didn't find ANY hits on
Google and this smacks of someone in the Debian world disabling it
as it's not clear if this ancient compression is legal to use.? In
my copy of D-rats, I have:
?? /usr/share/d-rats/libexec/lzhuf
Do you have that file?? Btw, more details are here:
??
Everyone: As we all know, D-Rats from Dan Smith has been essentially
abandoned for some time now.? When I was researching this issue, I
stumbled upon a fork of it which has new commits and might be a good
option for people to look at:

Re: Won't Send email to WL2K via RF Packet
A fresh install of the latest code instead of the Debian package fixed the issue I had.
I don't do Windows, so can't speculate on how or if it might work there.

Did you ever find a solution?
I can see that lzhuf is missing from the installation, but I cannot follow the wl2k.py code well enough to find where to copy it TO.
wl2k.py calls p.source_dir() when looking for lzhuf and that resolves to "." (current working dir) which is not terribly helpful.

Re: Exception: Not supported due to lack of license for lzhuf
Apparently, this is a long-standing issue.
I have a copy of lzhuf on my Linux machine, the only question is where to put it for D-RATS to find it.
Anyone have a clue??
Otherwise, I will go and put an absolute path in the wl2k.py module and try that.

Re: D-RATS and Soundmodem
Patrick,
? ?Thanks for all the info that you send out and all in your files section. I will say that I have been involved with HF Packet since the 1980's on Network 105 ..14.105 lsb 300 baud and it works Great...we have a large group that have HF/VHF gateways and all are message drops and keybrd to keybrd. I and several others have our BPQ 32 switches running there and other frequencies as well. In the beginning it was all hardware TNC, s now more and more are moving to UZ7HO modem and it works Fantastic. I run dual ports with UZ7HO on HF.
? ? With the collisions that happen with heavy traffic and HF propagation I can see the retry issue..We see very little of that on Network 105...(see network105 yahoo group)
? ? We have done work here in the Atlanta Metro Area with D-Rats on VHF Packet and FlDigi bpsk 250. The only issue is if you have many connected on RF you can see issues with missed comments.?
? ? Thanks again 73. Lee WB4QOJ ? ? AEC Paulding County ARES ? ? Serving West Metro Atlanta

Hi Mitch, Thank for your response. You make some good points. The reason I have been focused on PSK and other modes for HF is mostly because of the negative reports I have read about the reliability of HF packet. Some of the APRS folks go on and on about "retries from hell". But now that the latest software has multiple decoders available, it may worth giving 300 baud AFSK another look. (I try to avoid using the word "packet" when talking about D-RATS.) When I get my HF station going again, I'll send out an invitation to try D-RATS on HF again.
Thanks de, Patrick (N3TSZ)

Re: D-RATS and Soundmodem
I have to also ask.? "Why not HF packet?"? Same symbol rate and easy to implement.? The throughput is better than you might imagine.
Here's one reason why: multiple decoders The Direwolf packet modem allows you to use multiple decoders to catch other stations that are slightly off frequency.? On my HF packet node/BBS I use 3 decoders at 30 Hz spacing and it is very reliable for decode. I don't think you will experience that same level of robustness using BPSK on Linux soundmodem, BUT the good news is that the UZ7HO soundmodem allows "pairs" of decoders, and since the dialog allows that parameter to be set for BPSK 300, I am assuming it will work.? Naturally, the more "pairs" the harder you will tax the CPU. When you begin testing on HF, let me know.? I am happy to be of help. --

Re: D-Rats Current Version
Btw, I heard back from Dan on this mysterious 2014 Windows D-Rats build:
The 04172014 build was merely a custom version I rolled for someone with
a new custom form in it. That's all. No mapping or other functional
changes of any kind.
So that means that 02232012 is still the last release of D-Rats.
