Over the past 24 hours, I have had two successful QSO on two new
digital modes, new modes for me.
Last evening I had a QSO on 6 meters (my first non-repeater contact on
6M) using JT6M, I worked N4HN in North Carolina and then today on 6M I
worked Bruce N5SIX using FSK441.
I am currently using
It would be difficult to pause without notice with DV due to the latency
issue. This is one of the reasons that I do not expect DV to ever become
all that popular on HF. And if there are attempts to improve the
sensitivity and robustness, the latency would have to become even more
noticeable

... since I doubt that there is any chance to have wider
bandwidth modes such as you have on VHF and up with over 6 kHz wide
signals.
Hi Rick,
In USA, there is currently no

It is doing very well at this time.
If a short wave station is intefering, constantly, with licensed operations
in another part of the world, they are not following international
regulations to the letter. First, SWBC stations may NOT direct their
signals to an area of the world wherein that frequency is assigned to other
uses
Hi Gang,
Got a strange one for you -
If there is text left to be transmitted, the program will send all
except the last word, no matter how long or short the message may be,
until I hit Enter again. This happens not only with MixW but also
IZ8BLY's Hellschrieber so can't blame the software. I
Guys let's not start yet another rant on bandwidth.
All Bonnie was pointing out was that there is no
limit on DV at this time.
I really don't think anyone would run anything wider
that a SSB signal anyway.

Hi Bruce,
Digital Voice repeaters, using
Now I'm not a big 12 meter guy but from what i
remember it gets packed when open. On 10 meters 29.000

IF you could show under OPEN band conditions it might

I would love to try a DV repeater on upper HF...10m soulds like the
perfect spot. Repeaters are legal there and phone is legal so it should
be?
Also, on 17m don't go below 18.068, hihi.

OK, I will ask...
Am I correct in assuming that rules would need to change to allow
automatic operation?
Is it right to think the only improvement in communications would be
extending ground wave (since this would happen when the bands were not
open)?
What would happen when the bands did open?

A single channel time-multiplexed digital voice repeater is not
classified as a Repeater under FCC rules. It can transmit in
Hello, Howard
I snipped everything out except for that quoted, because I couldn't
think of a better reason than that asked in your question. So I say,
YES! (even if it might not be so, but let 'em think it is). Just by that,
inovation might surface in the process.
If we don't use the
Hi Simon.
I only allowed the HAM subtype of RTTY in PocketDigi mostly because of
my time lack to port everything. The other reason is to keep the UI
simple, which is probably the reason of your question. I asked the
same question about used submodes as you couple of months ago here at
this list.
