Ralph,
A group of us were beta testing a brand new mode for NBEMS on HF, especially
designed to survive extremely high, almost continuous, levels of static (such
as follows a hurricane). One station was in Florida, one in Alabama, one in
Georgia, and one in South Carolina. We were on 3854,

Download Digipan or Ham Radio Deluxe. Then there is also MixW. Use it, tune to
the freq, do some fiddling and find out!

I have decoded Dex 11 and occasionally Dex 16 (with FL-Digi) on that
frequency in the evening the past few days. N4UM and N8FQ were
testing , they also used Hell and Olivia. On the evening that I
listened in, Dex 11 seemed to perform the best. It will be most
interesting to see who Dex performs
Hi Rick,
FYI, our tests last night indicate that MFSK16 still copies the best at low
S/N, but only when there are no static crashes, but DEX16 or DEX11 have much
fewer errors when there are static crashes. The problem with MFSK16, as you
found, is the mistuning tolerance. For messaging, when
The problem with knowing where to tune any signal can be solved
completely by use of RS ID (as in MultiPSK, PocketDigi etc). It amazes
me we have had this technology for over a year now and very few people
seem to realize the potential of this.
Even with s/n ratios down around -15dB MultiPSK
I need help finding an MT63 QSO. Can anyone direct me to a time
and frequency? (I don't belong to MARS but can receive all
frequencies.)
Thanks and 73, Fred AK5U

Hi Mark,
I think G3PLX recently mentioned the same thing, with regard to USB sound
cards, as he found they have the biggest offset problems. However, in dealing
with the masses, if we can find a way to nullify the offset's effect long
enough to complete the ARQ transfer, it will work with

Couple of problems I've come across, Andy:
1. The heat sink on the top of the processor has loosened up, and is
no longer making solid contact with the processor itself. It could look
solid, but if it separates from the CPU even a little, it can cause
overheating.
2. The fan is
Maybe the fan in the power supply...they are most fragile

Just load Speedfan on that PC and interestingly it lists no fansm so
no temp display. The HD temp is diplayed, not a fan. I will have to
research and see if CPU temp monitoring devices are on this cheap

That is interesting that they are going to name a new mode DEX that is
similar to, but not the same as DominoEX. I liked using DEX as the
acronym for DominoEX. But the creator gets to pick the names.
I am very pleased that Murray is helping to develop a mode for NBEMS and

You know what? I have not used RS ID much as of late and it never even
entered my mind to use this last night. But then again, both stations
need to use Multipsk for that to work.
Are any other programs going to be adding the technology?

Andy,
Video ID is nice but when sent horizontal it has a very low average
power so won't work well in poor conditions. The RS ID is sequential
MFSK and will have 100% power. Also the Video ID doesn't automatically
tune in your software.
In MultiPSK it is possible to use both types of ID
