A big Thank You to Patrick N3TSZ for pointing me to the right place! 3.9 beta 3 up and running on an RPI4 4GB! The 4GB is amazing fast and reliable, I can't see how it could be improved on. Now to

Hello Luis, Thanks for the link. That's an interesting document but I cannot change anything around the IP transport. All I can tune here is the few parameters within D-Rats to optimize the file

HI David & Patrick, here other doc https://www.tapr.org/pdf/DCC2010-D-STAR-TCP-IPandDTN-EI7IG-OConnor.pdf

3600bps voice and FEC + 300bps sync bits + 900bps low speed data = 4800The JARL spec is here:?https://www.jarl.com/d-star/shogen.pdfTake two aspirin first.Patrick (N3TSZ)

Hello Patrick, Opps.. you're right around the Dstar slow-speed throughput. I think the 4800bps comes from the raw GMSK data for everything (voice and data). Anyway, is anyone aware of a document,

Patrick and David, Thanks for your feedback (and that of Al, who emailed me privately). All helpful thoughts and which tell me that additional research will be needed to best determine what my

Folks, I have had no problems setting up an experimental ratflector here. My intent is to put up a public ratflector primarily designated to serve the MDC/VA communities which are served by REF062

Hi David,D-RATS first came into being as a way to use the low speed data channel on D-STAR radios as a modem. The speed on D-STAR radios about 900bps. Later, when the network and TNC connections were

As a follow up to my own message, I see under D-rats Preferences --> Radios --> Transfers which have various parameters. I bet the Block size and pipeline length will have a huge impact on transfer

Hello Everyone, I recently stood up a private Ratflector for an new NPR-70 system we've deployed ( https://hackaday.io/project/164092-npr-new-packet-radio ). This NPR-70 system is essentially a

Sorry I got used to calling them? that. Raspberry Pi (4) -- AL M KF5SMH

AL, Pardon my ignorance here: RPI? Is this an app? Utility? Jack - KD4IZ

Give me a link please. Somebody point me in the right direction for RPI, I have searched high and low with no joy. Not been a particularly good day. -- AL M KF5SMH

I think you can also install this with: sudo apt install python-six This installs 1.12.0-0+rpt1 on Raspbian Buster. Hopefully this is new (or old) enough. --David KI6ZHD

Hi Glen, I'm the curator of HamPi -- the Ham Radio application collection for the Raspberry Pi. I can affirm to you that I have included the latest D-Rats in my HamPi image and once it goes to the
