Using the UDRC-II with Dire Wolf for Winlink packet radio communications

Chris - KC9AD
 

At this year's MicroHAMS Digital Conference, I attended John Langner's talk on Dire Wolf. I was led to believe that the Dire Wolf modem would enable Winlink packet on the Raspberry Pi + UDRC combination (aka Digi-Pi). But implementation details were sketchy, at least for me. So I did some Internet searching and experimentation, and I came up with some scattered bits of information that I put together to write this:

http://www.doutre.org/acs/rpi-packet.pdf

I make no claims to its completeness or accuracy. It works for me. If it helps you to advance the state of your art, pass it on. 73.

Re: Looking for information to build Analog/Digital Hotspot

Lloyd Mitchell
 

I suggest you look into the STM32 type boards for the repeater.

One is the http://www.repeater-builder.com/products/stm32-dvm.html board for the repeater interface

I highly suggest the DV-MEGA with a rasp pi as the mobile unit both of the boards can perform very well with the Pi-Star Firmware http://www.pistar.uk/index.php

There are many other boards and setup, but this one I have found to work with minimal other interfaces or mobile routers

I saw where NW Digital had a urdc board for Dstar, is this something that could be used or is another board or an arduino required.

I would like to add one to my DR1x repeater and have another as a mobile hotspot?

Thanks for all replies

SOLVED: ircDDB dashboard not displaying links

Ken Jamrogowicz
 

Somehow I managed to start up TWO copies of the ircddbgatewayd daemon. One running under opendv and another running under user "pi"

One of these was connecting and the other was not.  They were both providing data to the dashboard.....  


Re: ircDDB dashboard not displaying links

Ken Jamrogowicz
 

Just to clarify - when the status of linking changes, the web page produced by the dashboard is correct. This lasts for 5-20 seconds and then the list of linked stations disappears. The headers are still there but no data table.  If I unlink or link one of the repeaters, the table comes back but only lasts 5-20 seconds then disappears.


Re: ircDDB dashboard not displaying links

Ken Jamrogowicz
 

Actually It’s ircDDBGateway *Dashboard*

And it’s from the NW Digital web pages.


Re: ircDDB dashboard not displaying links

 

Isn't it ircDDBGateway, not ircDDB? Two different animals.

Re: WinDV Issue gateway list differs

Jim Moen <jim@...>
 

Yes, The hosts files installed with WinDV are quite out of date. Check https://www.k6jm.com/hs-setupwindv.htm in Reflector List section toward the bottom of the page for a way to install up to date hosts files.

The above recommends host files with just reflectors, but the same website ar-dns.net also has files that include gateways.

Many have switched to BlueDV, but WinDV still works when configured right. I still recommend taking a look at BlueDV....

I have WinDV on one PC and when using the "quick tunes" configuration, I get a LONG list of reflectors and gateway repeaters including  my nearby RF Dstar repeater.   This is useful for connecting to my local Dstar repeater via my ThumbDV.   For various reasons I want to use a a different PC.  I installed WinDV on it (same version as on other PC) but when I go to configure quick tunes I am not presented with the same lengthy list of repeaters to add to quick tunes.  I have tried all sorts of things but can't get the desired repeater even though i can with same software on different PC.  I have the call sign server st for Free*star

Don't forget the filtering you will need to design and build. I doubt any of those devices can be amplified without some extra filtering inline to keep them legal.

Re: UDRX ???

I don't know why your condescending quip at the end of your reply.
NWD asked all to "keep the faith" for a product that would provide
high speed data capability and be OS user friendly. A big loss to
the Amateur Radio packet radio community with the UDRX-440 concept
being dropped.

Sounds great, except I'd change that to "would have had quadrature outputs". The product won't see the light of day now. That's a bummer 'cuz back when it was announced I was quite interested in buying one.

Instead check out the HackRF, the LimeSDR, or the LimeSDR Mini: More capability than the UDRX would have had. Add an amp or three and you've got any mode you want on any of 100 kHz to 3.8 GHz (LimeSDR as an example). Has 6 Rx and 4 Tx connectors, so you can have an amp and/or antenna per band as well.

I think the Lime's do 10mW out, so an amp is pretty much required. This is not that dissimilar from my ANAN10 HF rig that has a separate amp to get it to 10 to 15W.

LimeSDR Mini: $140
LimeSDR: $300
HackRF: $300

Plenty to choose from these days.

Re: UDRX ???

 

1200 baud packet radio 30 years old in the PNW. I was looking forward to the UDRX as the next
generation to carry the mode forward as a plug and play Amateur Radio RADIO NETWORK device.
If only somebody (knudge knudge NWDR) would come out with an updated
(25 year old?) D4-10 that was not dependent on crystals for frequency
control. It would make a great pair with an dual port network TNC
(like the 25 year old Dataengine...)

There have been some comments that the 222 Mobile radio by the
Bridgecom BCM-220 will do 9600 and maybe better - but they ignore me
when I ask.

Re: UDRX-440 Board and Pi Star #hamvention

 

The UDRC supports creating hotspots and repeaters.

Jonathan recently ported the software for MMDVM to work with the UDRC, though it is still Alpha code, but for D-STAR see the numerous entries at:

This decision was not taken lightly. Rest assured we are still
interested in providing solutions in the space that the UDRX
envisioned and we will have future products in the space, but likely
taking a different approach.


Right now we are working on projects outlined in the "State of the

couple of weeks.

Re:  New UDRX-440 Board

Not certain I've read the product release correctly.
(in the future) will be be able to connect this new Board to a RPi 3 - that is running Pi-Star SW?

If yes, that should make a ~25Watt DMR/DSTAR/C4FM/P25/NXDN Hotspot...vs-a-vie the   20milliWatt   Pi Star Hotspots we're running today??

Comments?
