Re: How do I determine the install C-media device
In the Admin Menu, select item 9 - Start Bash Shell Interface Enter the command - lsusb You will get a list of USB devices attached to your Pi. Look for the C-Media device. The VID and PID (Vendor ID and Product ID) are given right after "ID" as shown in the clip below  0d8c is the vendor ID for C-Media 0012 is the PID for the CM108B 0013 is the PID for the CM119B I have tested both the CM108B and the CM119B on DINAH and SHARI and have found? the required audio level settings (RX and TX) are identical.

How do I determine the install C-media device
How can I tell what chip is built into my DINA, CM119B or CM108B USB audio codec integrated circuit? It appears to make a difference in how audio is adjusted for use in the allstars application.
NOTES FROM ALLSTAR
simpleusb output level calculations. First an explanation. The simpleusb
channel driver divides the number of mixer steps into 1000 steps. It is a
little more complicated than that depending on log or linear but basically
that is what is done. There has been a long standing bug in the simpleusb
channel driver that causes this to not work properly with genuine CM119B
chips. The divisor assumed 151 mixer steps for ALL chips and when the
CM119B chip is used which only has 37 steps the mapping was totally wrong.
Thus turning the level on the CM119B chips below about 375 actually muted
the chip. No values below that worked. This has now been corrected as the
code reads the number of steps from the chip rather than using a fixed
value and adjusts accordingly.
This change ONLY effects CM119B chips and ONLY the output level - item 3 or
4 on the simpleusb menu. After this update if you are using a CM119B chip
or you hear a difference in the output level (what you hear FROM Allstar)
you should adjust the level accordingly in the simpleusb-tune-menu settings.
There are currently two level methods. Method 0 is logarithmic and is the
default. Method 1 is linear. You can set these methods in the
simpleusb.conf file on a per node basis. The command is:
tx_audio_level_method=0 | 1 ; 0 is the default and is used if this
command does not appear in the config file.
Most users will not need to change the method. Soon there will be an
updated simpleusb-tune-menu program which will allow the setting of these
methods as well as a fine tuning DSP level change in addition to the
current mixer levels. Since the CM119B chip has about 75% less range steps
a finer DSP level will fill in the gaps.
Genuine CM119B chips are now commonly used as no other genuine chip is
being produced. The DMK-URI uses it as does the ARA boards produced by
George other will probably follow as the old stock runs out. Note also the
CM119B chips have less maximum output than the prior varieties. The DMK-URI
board has a 2X op-amp that can be jumpered into the circuit. The ARA rev 2
boards have a fixed 7X rail-to-rail op-amp which gives 5VP-P output into
100 ohms at maximum level.
I am sorry for not being more specific. The audio from my allstar node RPi3b+ to the Kenwood TMv71a is the audio that i am having problems with. The audio from the radio though the node sounds perfect.
I am using the cable that came with the DINAH and may not have noticed the fit. I will go back out to the remote site tomorrow and look for that issue and trim if needed.
I moved away from the area that I have accessed all of my repeaters from for years and set this radio up at my old home and am remoting into it from my new home.
Thank you for your help. I will reply to the group my findings.

Oops - I have used DINAH with the TM-V7A, not the TM-V71A.

I finally got my DINAH running into a Kenwood TMV71A as an all star node and it sounds like crap. I set up the TMV71A menu 518 and 519 to the appropriate settings. I adjusted everything i could on the allstars RPi3 node. I noticed a jumper mentioned jp1 in the manual but i do not know what it is for. Does anyone out here know? Does anyone have any experience with bad audio?

Thank you.? I was pretty sure that was going to be the answer.? I will look into your suggestions.? I still have much to learn about how all this stuff works.

I recently purchased a Dinah module and it is now connected to my mobile unit.? It was such an easy setup that I now would like to create a portable node for the local club.? But it needs to be on a budget and several members suggest they only want to use a handheld.? I am aware of no handheld with a data connector.? Has anyone tried using?it with any modified handheld (or maybe even a Baofeng) that has no 6-pin data connector?? Is it even possible? If so is there information somewhere about the modification or any handheld with a suitable external interface??
?Thank you.

KE5SQC, Randy here. I am using the FT-7900R with my DINAH and it works PERFECT!? No Issues.#52070

I was having trouble with my DINAH startup at the USB config stage. My two available DIN cables (I'd lost track of which came with the kit) were 8-pin so I had to remove the "center" pin on both ends. After the mod the insertion was fine, but there was a second issue- no COS. It turned out my Belkin cable was not 1:1 but appeared to be a crossover (1-2, 2-1, 3-4,4-3, etc). Fortunately my second cable was 1:1 and COS and PTT are working fine now.

I have not connected a DINAH to an FT 7900R? but checking the manual, I see that it has the standard packet interface using the 6 pin miniDIN connector so it should wok fine.

Has anyone successfully connected DINAH to a Yaesu FT7900R?

Re: DINAH using rigctl within allstar
I have no personal experience with HAMLIB but I believe your problem is you are missing a cable.? HamVOIP Allstar includes the HAMLIB but the connection for sending HAMLIB control commands to your rig is not made through a radio URI such as RIM, DINAH,? RA-35, etc. These URIs just provide the audio and radio keying (PTT, COS) interface. I think you also have to make a connection from a Raspberry Pi USB port to the 8 pin DIN connector labeled "PC" on your TM-V71A using a USB programming cable.? There is a "How To" link about using HAMLIB on the HamVOIIP website but it does not work for me. You can search the HamVOIP forum at?? ?Looks like lots of good information there.? If you need more help, I suggest you ask your question by sending it to? arm-allstar@....Steve - N8AR

DINAH using rigctl within allstar
I purchased the DINAH as a means to connect my V71a to an allstar node (RPI3b+) and control it (frequency agile) using the HAMLIB rigctl library. To test i am using the command " rigctl -m 227 -r /dev/ttyUSB0 -s 38400 -v " but instead of connecting i get the following result "rig_open: error = IO error".
dmesg command shows me this;

Re: Optimizing DTMF Tone Decode
Hi Chuck,
Thank you for the feedback.? I hope your 857D is an easy repair,
I have added the Icom IC-7100 to the list of radios compatible with DINAH..

Re: Optimizing DTMF Tone Decode
Hi Steve,
Just wanted to let you know that my FT-857D 6-pin DIN connector is partially dead.? That is the reason Dinah does not seem to work.? I connected my Kantronics KPC3+ to try to connect to another node and nothing. I then connected my SignalLink and again, nothing.? Tried multiple resets to try and get to factory defaults and no joy.
FYI, DINAH works with an Icom IC-7100.? You can add that radio to your list of radios with 6-pin that work, but that you have not personally tested.
Thanks for providing a new toy for me to learn.? This should be fun.
Regards,
Chuck, K6CES

Re: Optimizing DTMF Tone Decode
Hi Chuck,
I hooked my FT-857D up to SHARI again to test with the production version of DINAH since my previous testing was with various prototypes,? As you noted, the overmold precludes the miniDIN connector fully engaging.? I cured that with an Exacto knife as there is nothing but molding compound on the portion of the overmold that has to be removed.? I set menu item item No-073 to 1200bps and menu item No-071 to 50.? SHARI worked as expected with no changes required to the simpleusb.conf file.
