Looks like there is a lot of technical discussion about the AMBE chip on this yahoogroup. . Any plans for access on DMR yet on the NWdigital DVthumb? Thanks. 73, Barry

Cath, My reading of the Yaesu spec is that type 2 adds some FEC bits, external to the AMBE+2 vocoder. My suspicion is that they are applying those addition FEC bits to the AMBE sample but having the

ah ! Thank you John. Fresh samples ! The DN file is V/D type 2. I've just looked at the DR-1X manual and see that Yaesu don't give you the option to specify which of the two HR modes (V/D type 1 or

Cath, I have put some capture files in the Files -> DR-1X section of this group for you to use as samples. -- John D. Hays K7VE PO Box 1223, Edmonds, WA 98020-1223

None of the those WAV recordings seem to exists anymore John :( Either that or the dropbox site is blocked by my ISP.

What I'm hoping, is that Yaesu aren't using the AMBE-3000F-P25 or AMBE-3000F-SAT chips. If they are, then that would explain a couple of things. Those two other variants of the AMBE-3000 chip both

Hi John The yaesu document the one I'm using is this one (includes the V/D tyoe 2 mode)

Hi Cath, I have not seen documentation on V/D mode 2. Perhaps I missed it somewhere. I am aware that it's important that you pace the packet stream to/from the AMBE3000 chip by waiting for the AMBE

Hello John Thank you for your reply :) Yes 33 is the one I see it as being as well John. Well, their are 3 different rates Yaesu use .. 3600 .. 2450 voice .. 1150 fec .. V/D mode 1 .. index 33 2450

Cath, I don't know the chip (they may have done a software license deal). however it is AMBE+2 HR and FR ... the AMBE-3000 chips support this HR and it is index number 33 on page 83 at

Hello Does anyone out there know exactly which AMBE chip is used in the Yaesu Fusion radios ? I'm assuming it's one of the AMBE-3000 chips, but would like to know for sure if possible. Thanks

Good answer John. I've done some software over the past 2 days for fusion coding/decoding, raw C4FM <> raw audio samples. IT's currently in pure software form, but it's in need of an AMBE+2 chip now.

I don't know about others, but I write free open source software for the betterment of the community and to test out ideas. I just released a simple, real time, self configuring dashboard for

Anybody who has to ask that question would be getting paid just what their software is worth... I doubt anybody writing software - free or paid and supported - would ask that. Bill

KB9MWR :) What/Where is our the motivation to hand over our source code when we get nothing nothing in return from the money makers ?

Thanks guys, I’m using parallels on my mac at the moment and it works but windows is not my favourite system! Thats great news and will look forward to the release. Thanks in advance Jeremy for all

As one of the lucky Buster beta testers, I can tell you it will be worth the wait..... 73, Kenny, KU7M

Bryan will probably roll his eyes since he's heard this before, and I'll probably be forced to light myself on fire at some point in time as well, but... I am the author of Buster, the aforementioned

Just spotted this John I was hoping for news on the Mac os version as i have a thumb dv am certainly willing to beta test it but only have the thumb dv maybe your near to releasing it? My email
