[Freetel-codec2] More progress with SmallDV, a stereo mic input device
Hi all, Simplifying the SmallDV use in that a relay or quad bi-lateral switch is not needed in the setup. With a stereo mic input sound device and stereo out of course, I've split the the channels thus: Left mic in and left speaker out are receive Right mic in and left speaker out are transmit You still have to change the FDVCore mode but, as mentioned above, no fancy switching in going from Rx to Tx. So the extra $$$ in using the Creative Sound Blaster Play! 3 saves on the cost/complexity of a relay.

Re: [Freetel-codec2] Building smallDV with Codec2-dev, latest SVN
Thanks Erich, I've now tested "SmallDV" with available now USB audio devices: Creative Sound Blaster Play! 3 $35 AU available world-wide ASMedia HS100-B chipset Volans VL-UA01 $20 AU The "Play! 3" has stereo mic input. Decoded audio is slightly better. The Volans only has mono mic input. Both definitely better than the "el-cheapo" C-Media C119 USB audio devices. Though, these do have LED outputs and Vol Up, Down and Mute inputs. (I and others thought useful for repeater controllers) "SmallDV" uses only one audio device so, cannot get into buffer problems because of different sample rates, in and out. The long and short of this, don't be afraid to try another USB audio device. Problems may not be with the software.

Re: [Freetel-codec2] Building smallDV with Codec2-dev, latest SVN
Hi Bruce and all, First, "SmallDV" only uses ONE audio device. As marked on the device, Mic in, Headphones out. Matt uses a relay outside to swap things when in Transmit mode. But, in this world of consumer goods, you get what you pay for. Tested thus far: Working well === Creative Sound Blaster Play! not available, superceded Creative Sound Blaster Play! 3 the current model, available ID = 0: "hw:Sound Blaster Play! 3,0" VOLANDS VL-UA01 From PC shop, inexpensive ID = 0: "hw:USB Audio Device,0" Poor C-Media C119 clones Virtual 7.1Ch Sound, with Mute, Up & Down vol switches, red and green LEDS. (all six bought in 2011) We are using the device in Full Duplex, simultaneous audio in and audio out. Yes I understand the problem with two audio devices with different clocks. With the above testing, it's not the Linux driver but the firmware/hardware of the cheaper device causing problems. lsusb ID 0d8c:0014 C-Media Electronics, Inc. the VOLANS Chipset: ASMedia (HS100-B) ID 041e:324d Creative Technology, Ltd the Play! 3 There we have it, the Play! 3 is the best and at $35AU is not outrageous.

Hi all, Matt responded: Hi Alan, Thanks for the kind feedback. I'm curious to hear more about your project as you develop it. It sounds like fun. I should edit the web article to explain a little better how the command interface works. The syntax is: command=value ...and the equals-sign is required when providing value. So to control T/R on fdvcore, you want: MODE=TX MODE=RX See if that fixes the problem you are having. I'll make a note to myself to update the web page with a little better explanation. As for Linux vs. Raspi, I did most of the development on a full Linux box, and then debugged on RasPi, so both platforms should work equally well. The only real difference is that RasPi doesn't have enough CPU power to run some of the more CPU-intense modes like 700C. The 1600 mode should run just fine RasPi or a full-power Linux box. 73, Matt On 2/15/19 4:19 PM, Alan Beard wrote: Hi Matt, Steve and I have been trying to run your SmallDV application.

Thanks heaps Steve, So there's every chance "fdvcore" works and I can "throw together" a Codec2 box , quick and easy. Something I should demonstrate at the coming Wyong CCARC field day. Our ARNSW "Experimenters Group" is looking for demo projects. Don't let me stop the STM32 code development, It's part of the code optimisation with flow-ons back to the main code. I'm inclined to add to "fdvcore" the PTT stuff and add command line options for "TEXT" and PTT port as then I have no need for the Python code. I can "filsch" the PTT code from "freebeacon".

Re: [Freetel-codec2] Designing an SM1000 "module" for use in equipment
Hi Don and Richard, Raspberry Pi (and clones) hardware is so so cheap. Today's PIC is a Pi Zero Pi Zero W (wireless) $35AU My Banana Pi (original) here will run the FreeDV app quite well just don't run the waterfall display, a $50 board. Thus, an app is needed without the GUI and use a GPIO input for PTT. Wire up an I2C AtoD and DtoA or two USB audio dongles. And it will be fully up-gradable in the future. Repeater I'm interested in http://dmlinking.net/ for a split site full duplex repeater. Though my half-duplex one enables the transmitting site to hear their own audio (re-transmitted). In the experimental stage, quite handy.

Re: [Freetel-codec2] Networking Codec2 sites or repeaters
Hi Glen, So, do I get this right? It's 4pm Sydney time and the HAP chart from Perth shows a band of the 12 and 14MHz regions going in a circle from Darwin to Melbourne and all the east coast of Australia. http://www.sws.bom.gov.au/HF_Systems/1/1/1 HOWZAT (an Australian cricket term) And yes, I built (at Hankins, Newcastle) the HOWZAT pinball machines in about 1979. 40m here in the Sydney suburbs is too noisy, my neighbour's solar system, one side and the inverter air-conditioner the other, 30m is not bad. 20m quite OK. To Glen, I tried the link below and port 443 (HTTPS) was a no-go somewhere. Alan VK2ZIW On Thu, 31 Jan 2019 09:54:28 +1100, glen english wrote > Hi Sam > good point, this is all available online.

Hi Glen and all, You wrote: > 20m wont cover the whole country you'll need about 5 frequencies, at > least 2 simulatenous at all times, maybe 3 > And how many VHF repeaters do we have in our country, perhaps 300. Thanks for the magic diagrams, it shows that if Wyalla wants to talk to Adelaide, with the equipment they have, HF only, then there is a path via a repeater, if it were a skip distance away. Does this make sense? I aim to (well one is running now) start the process of giving this a try. So, I'm asking, what frequencies would you suggest? The Codan to be used will do 2 to 14MHz USB or LSB.

[Freetel-codec2] Networking Codec2 sites or repeaters
Hi David, Glen and Jeroen, 10m, the RF side concerns me, the ionosphere is just not co-operating. The MUF is not lifting up there so the coverage area isn't that good. Hence my concentrating on 20m as a max frequency. Using 20m a whole country can be covered. And it happens often enough, even daily for hours. Thanks Jeroen for the networking thoughts, as Full Duplex from one site on HF is realistically not possible. (I've looked at cavity designs for 100KHz split on 29MHz and you need about four cubic metres!!) As mentioned, I've picked up the Codan 8528 for a Codec2 repeater.

Re: [Freetel-codec2] add OpenBSD support
Hi all,
For Don Reid, compile of SVN 3995 on the ARM system here ran smoothly.
Question for Jeroen, what advantages does OpenBSD give us?
Linux is well supported on most ARM boards, Raspberry Pi etc..
System here: "uname -a"
Linux taitbox 3.10.108-BPI-M2U-Kernel #1 SMP Sat Nov 11 19:20:49 CST 2017
armv7l armv7l armv7l GNU/Linux
Though with the introduction of Power Management in kernels 4.15.xx onward
it's definitely caused me grief. Hence the above 3.10.xx kernel.
Systems that run for days then just stop, no logs are my worst nightmare.
And it's not limited to ARM systems, My ASRock Q1900-ITX failed similarly
until I disabled the GUI. I used systemctl to set default multiuser, no
graphics.

Re: [Freetel-codec2] Raspberry Pi 3 killer, RockPro64 is here and running
Thanks Jim, I've followed below and the PCI-E SATA card I obtained to fix a supposed fault in my Ubuntu Intel Q1900 box works a treat. I now have a 120Gb SSD on the RockPro64. Ayufan has installed some libraries that stop the installation of development software such as subversion and cmake, rather vital. I did: FILE2=/usr/lib/aarch64-linux-gnu/libEGL.so mkdir -p /data/fixup/usr/lib/aarch64-linux-gnu dpkg-divert --package libglvnd-dev --divert /data/fixup/$FILE2 --rename $FILE2 FILE2=/usr/lib/aarch64-linux-gnu/libGLESv1_CM.so dpkg-divert --package libglvnd-dev --divert /data/fixup/$FILE2 --rename $FILE2 FILE2=/usr/lib/aarch64-linux-gnu/libGLESv2.so dpkg-divert --package libglvnd-dev --divert /data/fixup/$FILE2 --rename $FILE2 Success: apt install libglvnd-dev Then "apt install cmake" etc. succeeds.

Hi all, The PINE64 group latest product the RockPro64 board is available, I have one. Six cores, 64 bit, 4Gb of ram AND a PCI-E slot awaiting a SATA disk controller. I've loaded Ubuntu with kernel 4.4.X but it doesn't "see" the SATA controller. Upgraded to 4.20.X kernel, SATA controller is seen but the HDMI GUI doesn't work. Price: about $130 AU. Not bad value.

Hi all, Another week passes and nothing logged by "parrot" on 14,153KHz 20m these last few days has been a wipeout in the daytime. Anyway, I'm compiling the codec2-dev SVN 3939 library and we'll run with that. Compile done and installed.

[Freetel-codec2] A Codec2 mode 700D repeater, WICEN NSW says Yes
Hi all, Rather than tie up a full ham transceiver for a Codec2 repeater, we have been given the go-ahead to use a WICEN NSW Codan. This radio model has been in my sights for 20m. All the "spare" HF radios I have are marine band and only do 2 - 8 MHz. Site: Ian McKenzie VK2ZIM's place Wellington, is, not close but he is onsite and internet is there. My Men's Shed site (Orchard Hills) is also a possibility but not ready yet. Software/computer Ubuntu 16.04.5 LTS on the Banana Pi M2 Berry is rock-solid and does the compile of codec2-dev in perhaps two minutes. SVN 3916 as of today. Linux taitbox 3.10.108-BPI-M2U-Kernel Yes, the kernel is old but it is not "complicated" by power management "stuff". The 4.18.X kernel "out of the box Fedora 30" freezes after a couple of days, can't use it. Eric VK2VE approached the committee and asked for me: 'WICEN Committee' 73 Alan VK2ZIW Evil flourishes when good men do nothing.

Thanks Steve and Glen, I'll do a SVN get and compile up my "parrot" repeater, right now. And, put it on-air. It'd be nice if somebody actually used it. 14.153MHz USB, put my callsign in the text to trigger repeat. The codec2-dev build just finished on the Banana Pi M2 Berry here.

Re: [Freetel-codec2] Getting Codec2 out there in ham circles
Hi all, When our Limited License scheme (no CW requirement) was introduced in about 1970 here in Australia, and lots of us were city workers, VHF FM in our cars was a new thing and repeaters helped a lot. It's about being involved. The ionosphere does bounce signals back to earth but, not to where I want!! Repeaters on VHF require high site locations, not always possible. So if my signal only goes upward at 10 deg at the lowest, I need either a satellite OR a repeater somewhere, at the skip distance away. Oscar 7 can give me perhaps 10 mins per day. My 2c.

Re: [Freetel-codec2] TWELP and Codec 2, accompanying modem
Hi David and all, Thanks David for your comparisons http://www.rowetel.com/?p=6513 As far as I can see looking at the DSP Innovations website, their processor includes both a modem and a speech codec. I couldn't determine if there was any accompanying data in their system. As I see it, accompanying data (the text in FreeDV) is so so useful in routing the signal. ie. Destination information. Are there any comparisons on complete systems, over air tests? Another point: Who do guarantee a support for "open-source" codec? On page: http://dspini.com/twelp/codec2-vs-twelp-700 During 911, whole companies were destroyed, so is "DSP Innovations Inc" a SINGLE POINT OF FAILURE.

And again, Hi all, I've been battling with my "parrot" repeater crashing, using the Banana Pi and Fedora 29 Linux. So I'm trialling a Banana Pi M2 Berry running Ubuntu 16.04 with an old old kernel 3.10 series. There are bugs, bad bugs with the latest AHCI-SUNXI and other laptop AHCI (SATA) drivers. It's all about Power Management. It seems kernels before 4.16.xx are OK. I've been battling with this for months I can't deploy an unreliable system Keep smiling Alan VK2ZIW On Thu, 22 Nov 2018 10:38:54 +1000, Alan Beard wrote > Hi again all, > > > 7177KHz LSB is being swamped by switchmode noise here in Emu Heights and 40m > is not much good all day. 20m is much better. > > > I'm going to switch to 14.236 USB weekdays and only 7177 on Sundays. > > > That Optus HFC cable box is the death of HF. > > > Remember, add the string "c2rpt" or VK2ZIW" to trigger a repeat. > > > Alan VK2ZIW > > > > > lOn Fri, 5 Oct 2018 08:02:29 +1000, Alan Beard wrote > > Hi all, > > > > > > On-air testing of the latest code is needed so please try the repeater. > > > > > > 7177KHz LSB mode 700D, put my callsign in the, sent text. > > > > > > Alan VK2ZIW > > > > > > > > On Wed, 26 Sep 2018 07:16:34 +1000, Alan Beard wrote > > > Hi Enrich, > > > > > > > > > Hardware for "parrot", Nothing in particular, just any Linux box. > > > > > > > > > To keep the power use down, I use a Raspberry Pi clone. > > > I use Fedora linux as, for the ARM processor they have made their > > > distribution > > > almost hardware independent.

Hi again all, 7177KHz LSB is being swamped by switchmode noise here in Emu Heights and 40m is not much good all day. 20m is much better. I'm going to switch to 14.236 USB weekdays and only 7177 on Sundays. That Optus HFC cable box is the death of HF. Remember, add the string "c2rpt" or VK2ZIW" to trigger a repeat.

[Freetel-codec2] "parrot" repeater now running with SVN 3896 library
Hi all, FYI: My parrot repeater is now running with the SVN 3896 version library. (modified with the patch sent in a previous email) I try to keep up with the latest code so that comparability with the FreeDV app can be checked on-air. === parrot === I now need to re-write my parrot.c code such that I don't need to modify the freedv_api.c library. I want to capture the Codec2 data for re-transmission along with the text. David's "freebeacon" code gets all the way to decoded audio with this call: nout = freedv_rx(fdv, speech_out, demod_in); I then have to use my added function to get "bits": unsigned char packed_codec_bitsTX[8000]; nin2 = freedv_get_rx_codec_bits(fdv, packed_codec_bitsTX); Along with a check that I actually want these "bits". The text string is checked with the "trigger" string and another string, not settable on the command line, a string to allow triggering by "any" repeater. The string is "c2rpt". Does anybody have any thoughts on how I should tackle the re-write? Alan VK2ZIW Evil flourishes when good men do nothing.

Hi all, Frequencies and times: 7177 here in Emu Plains is just not working. Do we have an 80m frequency for a night time net? Should I move to 20m, 14236 in the daytime?

Re: [Freetel-codec2] Codec 2 Hardware Implementation Question
Hi again Thomas, Thanks for letting know you are developing on a Nucleo-144. As far as I know, the SM1000 was both the modem and codec2 decoder/encoder. A box one put a mic and speaker on and then connect to an SSB transceiver thus not needing a computer. Perhaps an IO pin could select what text string to send with the voice. LO for just the user callsign. HI for user callsign and the repeater trigger string.

Re: [Freetel-codec2] Codec 2 Hardware Implementation Question
Hi Thomas, Please tell us the board you are using? Is it the Nucleo-144 ? There are lots of us who can compile the code but do not do much in hardware, so having a standard, ready made board, gets us going. Another question: Is there a way on, any STM, board to send a text string to trigger a Codec2 repeater? I have added "c2rpt" in my "parrot" repeater code such that users can trigger any repeater, not just the specific repeater desired by a callsign in the sent text. 6BK4 replaces the 73 Alan VK2ZIW On Fri, 26 Oct 2018 09:23:58 +0200, Kurin, Thomas wrote > Hello Casey, > > I'm currently running Codec2 on an STM32F767ZI Microcontroller > without problems.

Thanks Stuart,
I'm happy for anybody to use my development box
the Banana Pi (original) while I battle with the Banana M2 Berry and
getting the "u-boot" team to fully support this board as it's one of the few
ARM boards with a SATA port on the SoC.
Yes, I do need help with unix sys-admin, SSH in particular.

Hi Don, Noting your comments in SVN 3890. Do you need a login on a Pi system with disk space to burn, 500Gb ? You'll find the stm32 libraries in /usr/local and the current code in /home/data/alanb or you can upload with the script. just ssh wsjt...@www.unixservice.com.au, pwd wsjtdev2 Enter pwd twice as this gets you to the right box.

Re: [Freetel-codec2] Source for the Parrot repeater (Alan Beard)
Hi Enrich, Hardware for "parrot", Nothing in particular, just any Linux box. To keep the power use down, I use a Raspberry Pi clone. I use Fedora linux as, for the ARM processor they have made their distribution almost hardware independent. There are two steps in making a bootable SD card simples. Supports about 50 boards with one SD card image file. On the audio side I use a Behringer UCA202 USB device. That's because it has RCA line output connectors to which goes to my home-brew isolation box to my FT-450 transceiver. Any audio port device supported by Linux will do, must do 48000 samplerate. For PTT I use a PL2303 USB serial adapter to supply DTR to the above isolation box's opto-coupler. In the code there's provision to use a Pi GPIO port. Pi considerations = Since my Pi is a development box, it MUST have a good Hard Disk. So I'd pick a board with a High Speed Disk Interface and migrate the root filesystem onto that disk, off the SD card. SSDs are cheap and available and low power. That's what I use, a 128Gb. It's constantly writing log files and audio files and, I download the latest SVN code, compile and run, this way I help our developers by running, real time, their code.

Hi all, To allow you guys to setup a Parrot repeater, here is my sourcecode: www.unixservice.com.au/Parrot-src I've added a 2nd trigger string "c2rpt" so the users can trigger any repeater, not just the selected one.

Hi again Don, Using the Makefile on my Pi system here (Fedora 29) and adding my location of the C compiler: CROSS_COMPILE ?= arm-none-eabi- finds /usr/bin/arm-none-eabi-gcc and the library: PERIPHLIBNAME = /usr/local/lib/STM32F4xx_DSP_StdPeriph_Lib_V1.8.0 and all the library compiles and libstm32f4.a is generated Then we start to have troubles ../src/freedv_api.h includes stdio.h and sys/types.h so the making of unittests seemingly to be using the wrong C compiler. So I try just "make sm1000.elf" First it is stdint.h which should be stdint-gcc.h --- This is hard..

Re: [Freetel-codec2] 700D mode on SM1000
Hi David, Don and Steve, Can I be helpful trying to get the STM32 code running on the Nucleo64 boards that I have for the MMDVM project? Or perhaps, the Teensy 3.6? I use my Banana Pi armv7hl system to compile ARM code. The Arduino IDE is ported to ARM and runs well. (I need the DSP library that you use) On a side note, I've emailed SolderSmoke. I mentioned the commercials using TWELP and our Codec2 is open source. Bill (one of the main guys) responded, very interested. It's a bit frustrating here, nobody is trying my Parrot repeater. In time I'll have a better site for 40m for a repeater but, not soon as progress on a "radio corner" in my Men's Shed (Nepean) is coming slowly, very slowly. Does anybody have a site now?

Re: [Freetel-codec2] codec2-dev SVN 3832 question in freedv_api.c
Hi David,
Do I have to more initialising to get 700D working again with "parrot" ?
I notice from the SVN comments, work has been done on the OFDM modem
along the lines of different numbers of tones.
This is what I see when running "parrot":
Ctrl-C to exit
trigger string: " "
txFileName: txaudio.wav
PortAudio devNum: 16
samplerate: 48000
WaveFileWritePath: .
statusPageFile:
udp listener waiting on port 21234 - send me a command!
RX txtMsg: teniotl eeru ioele o wo
RX txtMsg: ce
RX txtMsg: enq cq tt lccq cq .llo i trld
RX txtMsg: o rieefpq he
RX txtMsg: lmeeotl ttple cq oqs egoSsrldoo/ c9 pe
So it's receiving nothing sensible from:
ve9qrp_700d_int1_fast_snr2dB.wav
No "Maybe Sync" etc.. and no Rx files are created.
If I revert to SVN 3775 (put back libcodec2.so.8) it all works.
Has the FreeDV app using the latest SVN been tested lately?

[Freetel-codec2] codec2-dev SVN 3827 and freebeacon (or my parrot)
Hi David and team,
Has anybody tried using "freebeacon" and the current
download of codec2-dev library?
(SVN 3827)
My "test" audio file is: ve9qrp_700d_int1_fast_snr2dB.wav
I'm trying to do again the patches for "parrot" but I've
lost receive except for the text strings.
All is fine on the working system (connected to the radio) based on SVN 3775.
And on 3784 on the PC here.
Over "freebeacon" on which "parrot" is based, I've enabled squelch (-9.0).
Has there been a change in the squelch software?
Somewhere between SVN 3784 and 3827, I believe we have a problem.
All I modify in freedv_api.c are to add two functions to get
packed_codec_bits only when they are valid and adding the f->validf flag
in freedv_api_internal.h and defining the added functions in freedv_api.h.
Thanks guys.

Re: [Freetel-codec2] Support in freedv_api for FreeRepeater ala parrot
Hi again David, I saw that my additions were in SVN 3787, so I thought that was that, the code was in. I've been busy with family issues so I've just let the parrot repeater run with the version I compiled on Aug 5th. So far, there has been no use of my repeater since then when I set the trigger string to "vk2ziw" either upper or lower case. (I added code to do UC to LC) Though as you see, I've put the, after Sunday broadcast QSOs received here, the 700C files. No one has triggered the repeater. and no text strings received contained anything like my callsign. Also, there has been no interest overseas or here in putting together a repeater. Most disappointing. Has there been any interest in "freeBeacon" ? Keep up the good work.

[Freetel-codec2] Support in freedv_api for FreeRepeater ala parrot
Hi David and team,
I notice in SVN 3825 the support for my "parrot" repeater is missing.
Can some of you better C programmers point me to how I can modify my code
to use the existing "freedv_api" to continue this repeater project without
me each time having to modify the API code?
This is the important bit: I want the repeater to re-transmit the digital
data as received including the text strings such that a second repeater can
also "interpret" the text strings.
Logging, at this point I want to save all received input. (if sync == true)
Keep up the good work.
Alan VK2ZIW

Re: [Freetel-codec2] ARM SBCs with SATA - was: Ubuntu 18 can't install subversion
Hi Dana and David, Back to the real issue, what do we use these SBC boards for? For me: 1) A Low Power server for my local Amateur Radio club. 10W or less with at least 100Gb of storage and affordable. Mission: Keep the electricity bill down. 2) The Codec2 repeater, on a mountain top somewhere. But needs to log perhaps 1Gb per day of received WAV files. 3) Be a General Purpose Linux box with all the development apps and a remote GUI interface eg. Joe Taylor K1JT compiled and tested the KVASD ARM binary on the BPi box here then made available the ARM binary for WSJT and WSJT-X. So, I'd dearly like to run a Real Pi but without a High Speed Disk interface on a real Pi, I have no reason to buy one. Yes, I have an original, a 256Mb one. SD cards broke (wore out) in days. That's why in about 2014 I went BPi and have never looked back. Keep smiling guys. I appreciate your thoughts. Current models with SATA on the SoC: Banana Pi M2 Ultra Banana Pi M2 Berry and not much else.

Re: [Freetel-codec2] Ubuntu 18 can't install subversion
Hi guys, This is why I choose Fedora. Eg. for my Banana Pi, Ubuntu, the kernel is version 3.10 whereas I'm running kernel 4.18.xx on Fedora29 !! And, most importantly, an "upgrade" gets me to the latest kernel as well as all the apps. On the Banana Pi Ubuntu, "apt-get upgrade" does not update the kernel. Also guys, I'm amazed, nobody seems to want a Pi with a high speed disk interface. Of these, so so few support a SATA disk (or SSD) with the interface on the SoC, not via USB.

Re: [Freetel-codec2] OFDM configurability
Hi Don and Steve,
I guess you've both seen my Parrot repeater, generated from FreeBeacon by David.
For the logging, I want to save the radio input audio, the decoded audio and
the packed_codec2_bits
using the freedv_api.c interface. I'd like to use it unmodified. But being a
rank amateur C programmer,
I can't figure how except by adding my own routine, to get packed_codec_bits[]
and to have it only
valid packets for retransmission. Thus I've added a flag f-> validf.
Thus I have to modify codec2-dev files freedv_api.c freedv_api.h and
freedv_api_internal.h
every time you guys update codec2-dev.
Can you guys help please?
int freedv_get_rx_codec_bits (struct freedv *f, unsigned char *bits_rx) {
memcpy(bits_rx, f->packed_codec_bits, f->nbyte_packed_codec_bits);
if (f->validf) {return f->nbyte_packed_codec_bits; } else return 0;
}
int freedv_get_rx_codec_bits700D (struct freedv *f, unsigned char *bits_tx) {
memcpy(bits_tx, f->packed_codec_bits_tx, f->nbyte_packed_codec_bits);
if (f->validf) {return f->nbyte_packed_codec_bits; } else return 0;
}

[Freetel-codec2] Parrot Repeater, now built with SVN 3775 codec2_dev
Hi all, After doing my mods to freedv_api.c to get packed_codec_bits[] after a freedv_rx() call, my Parrot repeater is running again. No problems. So, codec2_dev compiled up nicely on Fedora 28 armv7hl kernel 4.17.7-200.fc28.armv7hl which is as up to date as should be for a production machine. The box: Banana Pi (original, now four years old) and a 120Gb SSD on the BPi's SATA interface. (I'm trying to get a Banana Pi M2 Berry working under Fedora 29, but not working yet, no HDMI console. Looks like boot0 not running.) (Ubuntu does work, kernel 3.10.xx !!!)

Re: [Freetel-codec2] Parrot Repeater, now on 7177 LSB, trigger with "my call"
Hi all, This IS exciting stuff but in running the repeater here, I can't do any other HF except listen. Also, there's been no activity on the 7177 frequency for a week now. Also, I've not been asked for my Repeater software by anyone. Not a sole. Listening to 20m this morning, 14.195MHz USB, the ZL station was heard by several VKs but the VKs couldn't hear one-another. An obvious need for a repeater!! (in ZL). So, with my code and Banana Pi system quite reliable now, does anybody have a site for the said repeater?

Re: [Freetel-codec2] Parrot Repeater, now on 7177 LSB, trigger with "my call"
Hi guys,
This is what the Parrot receiver recorded to "send" back but I notice a crash
so I don't know
if this was successfully sent.
Play with David's Codec2 tools:
c2dec 700C 11_36am_to_radio.700C - | aplay -f S16
Quite good copy my end, the repeater end.

Hi David and others, Parrot repeater is working On my Intel box (Fedora 23) all seems well with my parrot.c but when Hil VK2AZ transmited to me, to my Banana Pi (Fedora 28), crash: The Log file shows Hil's transmissions.

Re: [Freetel-codec2] Parrot Repeater, now on 7177 LSB, trigger with "my call"
Hi all,
A few bugs with shutdown and startup cron scripts.
ie. If I use "pkill -u user parrot" the audio is left in a "bad" state.
If I then do a "record". it cleans up the audio and "parrot" will
run and initialise the audio without fault.
/usr/bin/arecord -D hw:2,0 -d 10 -f S16_LE > /dev/null
Now running 24x7.
Trigger with "vk2ziw" or "VK2ZIW" in your text.

Re: [Freetel-codec2] Parrot Repeater, now on 7190 LSB, trigger with "my call"
Good avo all,
Text messages are converted before Trigger String check, to lower case.
As in VK2ZIW or vk2ziw will both work.
The squelch feature has been added, set at -3.0 does need a command line option.
Have fun.

Re: [Freetel-codec2] Parrot Repeater, now on 7190 LSB, trigger with "my call"
Hi all,
I've fixed my crashing. I was closing a file that was not open.
I've tidied up the messages, so only when sync is detected...

Re: [Freetel-codec2] Parrot Repeater, now on 7190 LSB, trigger with "my call"
Thanks Jeroen,
With your mods and my additions, my parrot repeater is running sorta on my
Banana Pi using about 25% of one CPU (Banana Pi is dual core).
MRFE6S9160 (no 73 valves but I do have a 6BK4)
Repeater is running but crashes after about two mins, sometimes runs for 20
mins.
I check and restart it with a cron script every five mins.
"top" shows nothing.
All I get is: Segmentation fault (core dumped) parrot -c /dev/ttyUSB0
--dev 3
I've upgraded the kernel 4.17.6-200.fc28.armv7hl did a "dnf upgrade" but haven't
recompiled everything yet.

Re: [Freetel-codec2] Parrot Repeater, now on 7190 LSB, trigger with "my call"
Hi all,
The "trigger" string for Repeat Mode is settable on the command line. It is set
to my callsign.
The attached files are:
parrot.c
CMakeLists.txt
Put these in into the freebeacon download.
c2parrot.patch
is a patch file to upgrade codec2-dev to work with parrot.c.
Added and extended functions. Nothing removed.
Done against SVN 3756 with
svn diff --patch-compatible codec2-dev/src
Function freedv_codectx() now accepts mode 700D.
I can now "get" f->codec_packed_bits.
And, only returns with valid frames.

Re: [Freetel-codec2] Parrot Repeater, now on 7177 LSB
Hi Glen and Mark, Yes, the bandplan does need to be consulted, though 7177 seems quiet most of the time (here). To "trigger" my parrot repeater, there must be a space " " in the text you send. My testing of my code is mostly with the files from VE9QRP eg. ve9qrp_700d_int1_fast_snr2dB.wav and that has space characters in the text. Remember here, I'm not a guru C programmer and once I get it going usefully, including with the new modes 450 and 450PWB, I'll tidy up that code (the trigger) and use the trigger string on the command line. Sunday mornings are a problem for me, I'm a church goer. As I mentioned before, are we going to "settle" on mode 700D or the new 450 modes? ie. Have we got to the point where not much improvement in speech quality will happen so let's just run with what we've got?

Hi all, When I wrote: > In developing code for a repeater (parrot for now) that will "blow away" > the performance of our current FM repeaters, a "standard" mode would be good. In no way did I say "using FM" in our new repeaters. So please, because with these digital modes we now have effective squelch and "valid transmission" checks, we can use SSB transceivers. (or SDR) Back in 1960 or before, the noise quieting mute system was developed and for mobile two-way radio, FM was the way. AM was abandoned except for aircraft. HF repeaters never happened except 10m (which is VHF in the old school). We have a new opening.

[Freetel-codec2] Modes 450 and 450PWB, any progress on transmission of these?
Hi all, In developing code for a repeater (parrot for now) that will "blow away" the performance of our current FM repeaters, a "standard" mode would be good. We all have a "love-hate" relationship to AMBExxx but, it being stable, we have been able to develop repeaters for modes P25, D-Star, Fusion, DMR and NXDN. This gets us all involved in this new technology in both the software and RF areas. A good thing. So, not to be pushy, do we have any idea when these new modes will be in an app to use them over air? When will the code be ready for me to use in my parrot repeater? (full duplex isn't hard in software but is hard at the RF end, a transmitter running yet not interfering with the receiver) Alan VK2ZIW Evil flourishes when good men do nothing.
