Sorry guys,
On 22nd March lightning here in Emu Heights NSW destroyed:
FT-450
FT-977
ADSL router on Telstra line
Phone base on the Optus HFC cable
2x PCs, "main", "backup" and my wife's Hackintosh.
BUT, no data loss, all hard disks survived.
I put "main"'s disk in another box, works.
Thanks to
uot; guru to add something to CMakeLists.txt so we can
have a useful Revision number?

Hi all,
Lightning destroyed threee radios here including the FT-450D
running my Codec2 repeater.
BUT
I have to replace the feedline (RG58) as this took all the
lightning current. Actually it was the tree next door that took
the main hit. And I haven't looked in the AT-220 tuner.

Hi all,
Can I suggest we use Doug's AHRDF chat site for coordination of
FreeDV on-air testing.
As far as I can see, all the VK and ZL chat activity for VHF and up
has moved to www.vkspotter.com so it is unused.
I have asked both ON4KST and Hil VK2AZ for a Low Bitrate Digital Voice
chat group.
Hi all,
If I remember right, we had 44.x.x.x addresses with AX25 actually
well before the Public Internet happened.
I had it up on an XT with 704Kb memory and running Xenix because
Minix program sizes were too small to run the network stack.

Hi all,
I'm still recovering from lightning damage, 23/3/19, anyway...
Having a Codec2 repeater on HF is one thing but having an appliance
(small box, goes between speaker and mic to SSB transceiver)
might get some activity out there.

Hi all,
CORRECTION, takes 700C files WITH the c2 header.

Hi all,
In my testing of "parrot" a repeater for Codec2 mode 700D,
there have been crashes, I believe in the transmit of the
off-air Codec2 frames. They may be corrupt but these off-air
files can be successfully decoded to Q5 speech.
I'm looking for a command line tool to do this please?

Hi Adrain and David and group,
I've now two HackRF One's to "play" lower microwave bands with.
I'll give it a go with these.

Hi Adrian and David,
Noting the Mumble protocol and looking for a server, I found uMurmur on github
and tried to compile it on my Fedora 29 x86_64 here but am lost in cmake finding
the SDL library.
To make a cross band codec2 to FM repeater, can you give a quick run down
using your software?
ckPro64, all of them 64bit.
Today's PIC is a Pi3.

Hi all,
I looked at the RF design:
Starting with the HMC5416 RF Tx/Rx switch and am puzzled that 4W
on 50ohms is 20V ie. 40V peak to peak into that GaAs device. I did
look at the data sheet matching in/out circuits and noticed a DC connection
between ALL Rx, Tx and Ant. pins, through
Hi all,
Yes, I've been busy with other projects, building systems
for Men's Shed etc..
Is there any real interest in my "parrot" repeater?

Hi Steve and all,
At $25 ea. I've acquired two Teensy 4 boards for my Codec 2 project.
How's the code going?

Hi Steve and all,
Looking at the Teensy 4.0 memory map
https://www.pjrc.com/store/teensy40.html
I take it, the new compiler (or linker) can allocate code segments
into the right memory areas.
I have a Teensy 3.6 for MMDVM development, loaded but unused.
My Men's Shed (Orchard Hills, NSW) has
Hi all,
What is the state of the nation here?
Do we have any linking systems for Codec2 mode 700D?
Such that HF stations that do not have 3000+ bits/sec
capability or licensing can participate.

I think we are comparing apples to oranges.
As I see it, Codec2 voice compression is about determining what

I have here a RPi4B loaded with ARM-Allstar loaded and on it

I found data transmit problems probably because the "data" was not

Hi David and Bruce,
arm64 testing.
I've just installed Debian Buster on my Odroid N2 from:
https://forum.odroid.com/viewtopic.php?t=35658
and discovered we have GCC Ver 8.3
whereas Ubuntu on the Odroid N2 has GCC Ver 7.5
so we should have some of the new instructions.
It's GCC Ver 10 that has
