Looking at our Australian band-plan, the 7040 to 7060 KHz
segment is for Digital Data, but FT8 etc. are at 7074 to 7077 KHz.

envisage Digital Voice modes being within a 1KHz bandwidth?
So, can we use the Digital Data

The ionosphere can give a HF transmitter massive coverage

But, this does not help with medium distance two-way communications.

I second your thoughts Steve,
Start with a 64bit Pi of any flavour such as the Odroid N2 or Pi 4B.
Connect to the FPGA with USB3 or i2c whatever.
Also, can we make use of the GPU if there is OpenCL support?
Perhaps select a Pi or other ARM SBC with OpenCL support. I'd buy one.

Hi all,
API developers:
In my "parrot" repeater project, (cloned from "freebeacon")

On transmit however, I want to transmit the original modem

retransmission.

Good work team.
Our Western Sydney Nepean Men's Shed webSDR is available now 24x7
for all bands, 160m to 10m and beyond. I've now changed it's FreeDV
mode to 700E and can change it when asked easily, it's only a text change
in a script then stop/start.

Hi all,
Here in Western Sydney, http://110.143.195.8:8073
I found in the Python package csdr "__init__.py" where
the mode is set.
Now set to 700E, note also always in USB.
Also, with OpenWebRX, several listeners can use it at the same time.
But all users have to use the same band as the
Hi David,
Can I participate? My Pi clone (Banana Pi M2 Berry) and transceiver
FT897D are running here 24x7. Audio by a Behringer UCA 202 the original
Texas Instruments USB audio dongle and PTT via serial port.
Could my Pi receive and retransmit what it received?
7053KHz is not too cluttered but
Hi David and Simon,
Could you use a SSH connection to my Pi here with the FT-897D
connected to it? (and backyard dipole here in Sydney)
You will have to email or ring me to arrange frequencies and modes
ie. USB/LSB, 80m, 40m or 20m.
>From the shell on the PI, you can ssh out or use "wget" to

Brisbane, Melbourne, Adelaide, Tassy anywhere in skip distance
to Sydney.
Can you please test the system below?

Hello Tim,
It's great to have you onboard. I'm more of an "implimenter", by no means good
at C or C++.
So I can't help to that depth.
I can compile code on ARM and Intel Linux platforms here and with transceivers,
give it a go.
So, if I can be useful.

This is amateur experimentation.

Hi all,
Following the Activity weekend, 5/6 Nov. when I had my "parrot"
repeater running here in Sydney Australia, nothing was heard.
It's been running a week now. Nothing heard.
There has been plenty of FT8 and WSJT signals heard on 17m, so
the band has not been dead.
So, it's Tx is now OFF.
Hi again all,
It's back on now and has been for a week now.
Is there any interest at all or am I wasting time?

Hi guys,
I'll try to have my 700E repeater identing for you from here, Sydney, Australia.
1600Z translates to 3:00am here.
7177KHz, about 20W

Hi Simon,
Have you seen the "OpenWebRX" project on Github,
https://github.com/jketterl/openwebrx ?
I'm running it in Sydney here, on a Men's Shed building with a 9m pole as
antenna. An excellent HF receiver.
It's mostly written in Python3 and basically pipes command line utilities
together
Hi all,
I just got a reply from a computer literate ham doing Q65 a mode
from the WSJT suite saying, no interest in Digital Voice.
What is the point of our Amateur Radio in NOT looking at communications,
sending useful messages.
Though I do do some meteor scatter which only transmits callsigns
Hi Ugo,
I run a "freebeacon" here and when triggered, will transmit back to you or ident
every 15mins on Mode 700E on 7177 KHz LSB as it's the only 40m frequency
mentioned on QSO.freedv.org.
That is what you need over there in Europe.
Yes it ties up one transceiver here and one antenna but
try soon, also if, in this period, on my experience, my good "windom"

Hi all,
You may not remember, but early in the development of Codec2 (~2016)
a piece of code "freebeacon.c" was written as a reverse beacon.
It received and decoded a Codec2 signal, compiled stats, bit errors,
and transmitted that information back in the text space along with
a Codec2 encoded

Hi all,
I've been pushing the idea of "repeaters on HF" since
around 2016, ever since I saw the opportunity within
David's "freebeacon" code to add retransmit the recorded
audio or perhaps the data after FEC. Half duplex at this stage,
full duplex with two sites will come.
Thankyou David for

Thanks,
In the FreeDV Activity Day Announcement can we have an alternative frequency
mentioned
for "freebeacon" and perhaps to require the "trigger" string to have say "#",
never found in callsigns.
My "freebeacon" here has never been set to have no trigger string.
But if it is triggered
101 - 200 of 272 matches
