Unfortunately Tigertronics don't mark their products with Serial Numbers or production date, so you have no way of knowing for sure. The newest units have had the 33uF substitution, but nothing else. -- Vy 73 de OZ1PIF/5Q2M, Peter Thank you Peter. I've been looking at external sound cards to use with a laptop for portable work. The internal unit in my laptop doesn't work all that well and my thinking was if I use a good quality external unit it can move to a new laptop when I upgrade some day. Tim, N9PUZ
Re: [digitalradio] Sound Cards
Tim, have you tried the USB sound adapter? The low end noise that the standard SignaLink has is not there and you can just use VOX for PTT switching. It is also an external soundcard. For only $7.50, you can hardly go wrong! If you can handle tiny chips, there is also a PTT output that you can bring to the outside. http://www.geeks.com/details.asp?invtid=HE-280Bcat=SND 73, Skip KH6TY Thank you Peter.

[digitalradio] Re: Sound Cards
I would choose a sound card with the lowest THD% or Total Harmonic Distortion if you can find the specs. Also choose a sound card with a high SNR (signal to noise ratio) and you should be pretty happy with the card, Then make sure to use some extra ferrite on the audio lines to help keep any extra rf type of noise out, and you could go pretty extreme with some shielded audio cables. I have had 5 cards now and the only one I have been happy with was the Turtle Beach Santa Cruz which used a crystal chip set. It was a super clean card and low priced but, they do not support it anymore I can not run it on windows 7 Emoticon10.gif
Re: [digitalradio] Sound Cards
Tiny circuit work isn't a problem. Do you have a link to that modification? It's sort of amazing that $7.50 will get a working external sound card but obviously you've tried this and found it to work. I actually had a couple of other items to order from them as well. Spreads out the shipping. Tim, N9PUZ kh6ty wrote: Tim, have you tried the USB sound adapter? The low end noise that the standard SignaLink has is not there and you can just use VOX for PTT switching.

Re: [digitalradio] Sound Cards
Try this link, Tim. I ordered five of the adapters, all had the C-Media chip, and all worked very well. Don't know if Geeks.com can guarantee shipping only the C-Media version, but maybe you can ask them. The audio output is a little less than with some soundcards, but that is usually not a problem - just readjust the level controls under Windows. Also use this adapter under Linux for NBEMS. The PTT output works, but it is hard for me to work with such tiny parts, so I just use VOX for PTT switching - no need to even open it up. Be careful about putting too much strain on the USB adapter when it is plugged into the USB port as you can break the connection to the circuit board if it bends too far. http://images.qrvc.com/usbfob.pdf Good luck! 73, Skip KH6TY NBEMS Development Team Tim N9PUZ wrote: Tiny circuit work isn't a problem.

30 years seems a stretch - since I think Linux first saw the light of the Internet in about 1992. Let's see - 30 years ago - that's just after people started pirating paper tapes of Microsoft Basic... grin 73, Bob, KD7NM -Original Message- From: digitalradio@yahoogroups.com [mailto:digitalra...@yahoogroups.com] On Behalf Of Simon (HB9DRV) Sent: Thursday, June 11, 2009 9:54 AM To: digitalradio@yahoogroups.com Subject: Re: [digitalradio] Boot discs for emcomm/ham radio - Original Message - From: Steinar Aanesland saa...@broadpark.no Rick, I think Windoze is some sort of Lunix clone In the history of Windows there is some Linux - about 30 years ago or so.

[digitalradio] MMSSTV: Chosing a soundcard besides it's default?
Hey group. Having trouble finding an answer, hoping you can help. Running short on time too. In MMSSTV, I can't seem to change from one sound card to the other. I have two in the PC, but MMSSTV wants to take the wrong one. Any ideas, or should I try another program? f, k2ncc

Did you change the device ID in set-up MMSSTV /MISC area ? Andy K3UK On Thu, Jun 18, 2009 at 9:35 PM, frankk2nccfrank.k2...@gmail.com wrote: Hey group.

I get a little spoiled when I can play radio more than configure software! Each choice in Device ID still goes to the wrong card if I try to adjust the soundcard levels in MMSSTV. Other choices give me Can't open Sound card (n). But have since setup DM780 for SSTV, as that's what I use the most anyway. Worst case, I can always go back to MixW. Thank you for the pointer! f
