Here is a very good youtube video on sound card mode audio level adjustments:

Merry Christmas to the Group,
I am looking to buy another HF radio for PSK/digital. I am asking what
features I look for and why. Next question, what radio offers more bang for
the money and why
. Olivia 16/500 is much slower but goes way into the noise
where I've had terrible results with MFSK16 under the same conditions. And if
8/250 Olivia (slower yet) doesn't do it, I just turn off the HF rig.
BTW, my experience is almost all on 80m with NVIS antennae.

And stations that don't have WRAP get to see the message too.

Besides being a great drill and practice should we need to intercommunicate
with the military during a major emergency, the event is a lot of fun and is a
great way to show our support for the military.
I'd highly encourage all to participate.

Good thing about Olivia is, Andy...
If you're not completely satisfied, she'll give you a full refund of your
purchase price!

Overdriving your audio into the rig causes your intended transmitted audio in
the passband to go non-linear and put images out all over the waterfall.
Here's a great video on the subject:

Maybe the fact that it was 10 bucks may have something to
do with it.

When purchasing a new radio this last week I decided to also

Here's the text from our net this morning. This is unedited with the exception
of me
It was good to see a few of the 13 Colonies stations on PSK.
I wish more of the special event stations would work digital. It would really
open it up to the low profile stations.

I don't think anyone should suggest limiting to contests to fixed frequencies,
but it damn sure would be nice if some of the mindless RTTY contesters would
start showing some common courtesy by listening a second or two before stomping
on QSO's in progress.
-Dave, KB3FXI

. This procedure took
about 1 minute of my time and I was assured that I was not interfering with a
qso in progress.
It's just common sense and common courtesy.
-Dave, KB3FXI
BTW, I find the CW contesters to be less likely to QRM. And if they do, it
really has no effect on most of the digital modes
, the leaks were quickly
repaired.
You can have situations where nearby signals mix and cause interference on the
input, too. It was amazing to me that the noise problems we had got right past
the CTCSS.

Do you suppose they're running their RTTY station in such a way that they can
neither hear or see a signal?

change your sound card or switch to a USB mic. Here's a video I made on
that subject of calibration using CheckSR.exe and FLDIGI:

We're hoping to be installing UHF and VHF vertical yagi's at the Skyview Radio

the DominoEx 8 as you suggest.
