In order to have a really robust and accurate mode, I would like to see
an ARQ mode 500 Hz or less. This would allow for a good throughput and
error free data and images, etc. Consider that you can get at least four
500 Hz signals in the width of one voice signal. The 100 KHz digital/CW
I never meant to say we should go back to CW for emergency

I'll be honest here, I don't know if Pactor starts in mode P1 or P2 or
maybe either. I do know it doesn't connect in P3. It connects in one
of the slower modes and then expands to P3 if the signal is
sufficient. This means every pactor connection, where P3 is
available, does this and is one of

It was a joke. Sorry for the confusion.

every organization in the country prior to conducting any testing. They
make certain they are legal, and then do their best to select the most
appropriate frequency

It would be reasonable to allowswitching
between voice, data and image in the phone segment, all using the same

We published two articles in QEX and another one in CQ VHF asking for

Any other suggestions?

We have an FCC license, albeit Experimental, just like you do, so our HSMM

is required for our links.

not cooperating.

Are you saying that this is something for HF? I can see it working if
you have a wide BW area, but on HF we need to conserve spectrum to a
much greater degree than on VHF and up. I don't see any possibility of
anything much greater than 3 or 3.5 KHz below 28 MHz in the foreseeable

I suspect if there was one, wide bandwidth, 10 kHz channel on each ham

all hams. This is certainly less than what is currently designated
by the different modes/protocols like winlink/pactor 3, wide olivia,

Danny,
The 6M vertical we are using must be two 1/2 waves in phase? It's over 24'
tall !
For a 6M vertical, that's a MONSTER to me (HI).
Although your inverted L sounds intersting. I have used a simple indoor 1/2
wave
dipole on 6M, but never thought of using an inverted L. Interesting!
