Has anyone else tried to characterize the SignaLinkUSB frequency
response and S/N properties?
I Have, and, to put it mildly, I'm underwhelmed. Compared to my old
homebrew interface combined with an aged SoundBlaster16 PCI it sucks as
far as pure data is concerned (I have spectralab dumps to

Thanks Dave, any suggested day/time for a sked?

The real interesting question here is: how important is this in real
life? Both interfaces work fine doing everyday PSK31, RTTY, SSTV etc,
but how critical does it become when working signals near the detection
limit as in WSJT JT65, FSK441 and very weak HF PSK31?

This is something

Now, in terms of S/N ratio... I find it hard to believe that quieter
isn't better no matter how you look at it.
But at what point does it become insignificant? I've heard of people
using low-noise preamps on

I'll not repeat my my message here, just indicate which message it's
about. I have been accused of damaging Tigertronics reputation and
possibly their business
I might suggest looking at some discussions that were recently held on
this subject on the illinoisdigitalham yahoogroup. The group originally
was for a specific geographic area but now is a general digital radio
type forum and allows discussion of digital related issues.

My signalink usb measures +- 1db from 200hz to 5khz. I did not try to measure
outside this range since I consider it irrelevant for digital.
The s/n measures 73db over the same range with 20db of headroom.

Hello,
I have flarq running here and would like to give it a try. Anybody
out there want to suggest a good frequency?

If you use a big shovel you will eventually dig up something bad. So ask
yourself this, does the product work? Does the product do what it is intended
to do? Does the product stay within parameters that are expectable within
rules?
I was making my decision between Tigertronics or Rigblaster. I

On two meters, we use 144.144 around 1500 Hz using DominoEx 11.
On HF, we use 3584 around 1500 Hz, and MFSK16.
