Re: Sqelch Open attached to VOLUME DOWN in Schematic
¿ªÔÆÌåÓýThat's the only properly supported way Allstarlink/HamVoIP's
SimpleUSB driver does PTT. The DINAH and other interfaces like it
just converts that to essentially a continuous volume down press.
I understand Direwolf has a configuration option to support this
method of PTT as well, though it didn't used to. Even echolink on
Windows now supports this keying method, I believe, with URI
support, though I don't know how it gets around turning the output
volume down at the same time if it does. You can use an unmodified fob from a MPOW 071 USB headset on
Linux with ASL/HamVoIP's SimpleUSB as a radio-less node
configuration to test this. Volume down is momentary PTT.

Re: Sqelch Open attached to VOLUME DOWN in Schematic
¿ªÔÆÌåÓýI¡¯m not convinced that Direwolf is the problem. The electrical design of DINAH connects the squelch logic signal to the Volume Down pin.? For example, this gets used for the volume up and down buttons on a USB headset that uses this chip.? ? I¡¯m going to guess that the CM108 driver on Linux (raspberry Pi) doesn¡¯t support the hardware volume controls.? I should go find the linux driver and see for myself. ??I¡¯m working with someone from core audio on Windows to help me find the Widows driver and see how it handle this. ? I¡¯m curious as to why they decided to connect the squelch signal to this pin rather than one of the available GPIOs. (See the schematic). It seems reasonable to me for the driver to turn the volume down when someone probes the volume down pin. ??It has the feel of a bad electrical decision rather than a software problem. But I¡¯m willing to bet there was a good reason. Perhaps it was because early adopters re-used the logic lines available in existing headsets/Adapters? And on those boards perhaps the GPIO pins weren¡¯t accessible. But I the case of DINAH they are doing their on PCB. SO the decision could have been made differently.? Perhaps they didn¡¯t do it because the underlying software depended on this choice?? ? Does anyone know the story? ? From: [email protected] <[email protected]> On Behalf Of

Sqelch Open attached to VOLUME DOWN in Schematic
So I'm hitting the standard problem in Windows that Pin6 of the DIN is connected to the VOLDN pin on the CM119B in DINAH. This results in the volume being turned down every time the squelch opens on the radio.??
So here is the question:? Why didn't DINAH use one of the available GPIO pins instead of VOLDN?? Is it because the software that is typically used with DINAH doesn't support that? I'd love to use DINAH on Windows.? I'm perfectly happy to update the client software to support a GPIO in open source projects.? I'm an embedded software developer, and I've recently re-joined the Windows team at Microsoft As well.? So I'd be pleased to help fix this... But I'll need a bit more information on what drove that electrical decision in the schematic. And I'll need to know the key pieces of software that DINAH is targeting.? I'm aware of DireWolf, but what else? Alan Ludwig N7JTI -- and Packet user as well as: Principal Software Development Engineer? Device Security Team Enterprise and Security? Microsoft |

COS, was Re: [DINAH] COMPREHENSIVE LIST OF COMPATIBLE RADIOS?
¿ªÔÆÌåÓýSpeaking of that: Can the TM-G707 be configured to use squelch to drive COS rather
than carrier? Somehow, I doubt it. If not, do you know of a
hardware mod for either that radio or the TM-D700A to make this
happen? I have the opportunity to get a TM-G707 possibly for free. I am currently using a TM-D700A as a remote base, and this is
really bugging me. Sometimes, a Fusion repeater will go into
digital mode and cause my remote base to key with no audio, since
CTCSS is enabled, but COS is hard-wired to carrier. Also, this
means I can't take advantage of repeaters with gated PL's to
create a better link. This is also the case when using this radio
just as a normal cross-band repeater. I realize this isn't strictly topical for the list, so feel free
to write privately. On 6/13/2022 6:39 PM, Scott wrote:

DTMF 3 and 6 not being decoded
Recently installed most current version of Hamvoip.? Running on a RPi3b+ with a Dinah and a Kenwood TM-G707.? Everything works great when I use my 2nd G707 and I can see all DTMF being decoded properly in the CLI.?
When I use my Baofeng UV5 HT, my TYT, or my Retevis I am unable to get 3 and 6 to decode.? I've set my levels properly using the PDF and video.? Everything else decodes fine.? I've muted DTMF on the HT's as well and I've checked to make sure they are in Wideband. What am I missing here?? Why is only 3 and 6 not decoding.? All the others decode correctly every time. Any help would be appreciated.? I know people are using Baofengs to access their node.? How? Scott/KG6LJY Thanks. |

Re: Dinah Problem
If the troubleshooting steps Larry suggested in the previous message do not solve your problem, you can return the DINAH to us and we will fix it for you.? Please email us at kitsforhams@...?to make arrangements.

Re: Dinah Problem
Check solder joints. Look for solder Bridges...transistors, diodes or IC's installed backwards. After that break out the scope or logic analyzer. Trace +5 from the USB to all parts on the board. Trace the USB T-R signals to the Audio chip. Look at the output of the audio chip with a scope.
Or send it back and they will repair it for a fee.. Larry W8LM |

Re: Radios w/o a packet port
Indeed you adjust DINAH sound levels on Raspberry?OS using alsamixer.? Works fine. As you note, the DINAH is just a USB sound card which can also generate PTT from a sound card GPIO pin. On Wed, May 4, 2022 at 10:20 PM Lee Bengston <kilo5dat@...> wrote: Hello, --

issue with radio
hi all, i have a kenwood tmv 71, dinah and ASL node... everything was working fine up until two days ago.
i can key up the ASL node via Echolink, or another user who is linked to my node can key it up, but somehow it does not key up when the radio is doing the tx.. so i can key my base radio(which is connected to the dinah and asl) from my HT, but this doe not key up the node... any advise.... on what needs to be checked in radio or ASL? |

Radios w/o a packet port
Hello,
Currently I'm using an inexpensive USB sound dongle (C-Media) with Direwolf. PTT is handled via the RTS pin on a serial port, which is run through a transistor circuit. The radio (Alinco DR-605T) doesn't have a packet port, but I made a cable, and everything works well. I adjust input and ouput levels via alsamixer in Linux. I want to change to a different radio, which also doesn't have a packet port, but it would be easy to make a cable to adapt from the packet port on the DINAH to the radio. The DINAH is appealing because PTT is handled by the GPIO pin on the C-Media chip, so it saves a USB connection.? Is there anything that would prevent me from treating the Dinah the same as my other USB sound device and adjusting levels via alsamixer? Thanks, Lee K5DAT |

Dinah Problem
Hello, I RX'd my Dinah and assembled it. I am working with a Direwolf group and mine was not digipeating or sending beacons. It is responding to my PTT requests. I have cut JP3 and verified that there is no continuity there.
I don't think the audio path is working. I tried another Dinah, loaned to me by another ham, and his works perfectly. What should I do next? Thanks, Tim KA1YBS |
