[digitalradio] Digital Voice News - VK5DGR's Open Source Codec
All, Dave Rowe, VK5DGR, has just released an open source speech codec that could potentially be used in such digital voice applications as FDMDV and WinDRM. Dave says that his new CODEC2 needs work, but the speech quality of the Alpha release is pretty good. He has a few audio samples of CODEC2 and the proprietary codec MELP (for comparison) on his website: http://www.rowetel.com/blog/?page_id=452 For more information, visit Dave's main site at http://www.rowetel.com/blog/ Tony -K2MO
RE: [digitalradio] HOW TO- Packet Keyboard-to-Keyboard operation?
Mike... You can also put your TNC in Converse mode. This will allow you to transmit in the blind like calling CQ or just announcing you are Listening. There should be Converse mode for your TNC.

Yes, I'm a packet newb. I just got my VHF packet system running (817/Signalink USB/Laptop/AGW/PacTerm) and can connect to a couple of local BBS. But I would like to understand how to actually do a keyboard to keyboard QSO using packet. I assume this does NOT go through a BBS. I've ready about 'keyboard to' but cannot find actual instructions about how to actually go about it. I have a willing friend ham on the other end that will work with me. Eventually I'd like to incorporate PacLink and Thunderbird and make that same keyboard-to-keyboard QSO using the Thunderbird Email client interface. Thanks for any pointers, URLs, docs. Mike
[digitalradio] de AA5JG FS: Kenwood TS2000 HF/VHF/UHF transceiver
-- Forwarded message -- From: John Geiger aa...@yahoo.com Date: Thu, Aug 26, 2010 at 11:35 AM Subject: [KenwoodTS-2000] FS: Kenwood TS2000 HF/VHF/UHF transceiver To: kenwoodts-2...@yahoogroups.com I have for sale or trade a 2008 model Kenwood TS2000 that does 100 watts on HF, 6m, and 2m, and 50 watts on 70cm. I bought this radio used from Ham Radio Outlet at the beginning of June, so it has been checked out recently and found to work perfectly. Really like it but life things come up and I need to downsize the shack a bit. This radio has IF DSP so no optional filters are needed. It also has full duplex for the satellites, a built in TCXO, a 2m/70cm subreceiver for listening to the local repeaters while operating on the main receiver, and a built in TNC. It will also do crossband repeat so you can get on HF or 6m while walking around town with an HT-what a neat feature! It is in very good condition with a couple of light scratches on the top of the case (I doubt they would show up in a picture). It comes with the hand mic, power cord, and manual. I think I still have the original box but it is missing the stryofoam inserts, though. I am asking $1000 for it plus shipping, but can also meet for an inperson deal in the Southwest Oklahoma/OKC/North Texas area. You will not be disappointed with this radio-it does it all and does it all pretty well. 73s John AA5JG Lawton, OK

Thanks for all the replies. Boy, that seems waay too easy for something related to digital packet (ha ha). I'll give it a try soon. 73's Mike N3WF --- In digitalradio@yahoogroups.com, Joseph Yakoski jyako...@... wrote: Mike... You can also put your TNC in Converse mode.

I refuse to go to the yahoo site every time I post. Trying to get dial up started. Till then Questions or comments IM me on the yahoo system ID W0JAB of course. John
Re: [digitalradio] Digital Voice News - VK5DGR's Open Source Codec
This is very, very good news, and it may turn out to be a very big deal. It will be fun to hear reports from the early adopters. There aren't many people who can write this kind of code -- if you like where Dave is headed, you may want to donate to his CODEC2 effort that's referred to in the link below. Ever since we all discovered that MELP was not legally available, we've all been waiting for something good that's open source. CODEC2 may allow a narrow enough bandwidth for widespread use on HF, and it may provide an alternative for VHF/UHF digital voice in the future. While I don't begrudge D-Star's use of the $25 AMBE proprietary codec on a chip, that approach prevents the kind of experimentation that hams are famous for. A software only codec would be very welcome as the future unfolds Jim - K6JM - Original Message - From: Tony To: digitalradio@yahoogroups.com Sent: Thursday, August 26, 2010 12:24 AM Subject: [digitalradio] Digital Voice News - VK5DGR's Open Source Codec All, Dave Rowe, VK5DGR, has just released an open source speech codec that could potentially be used in such digital voice applications as FDMDV and WinDRM.
