Hi. This question may actually be for the Allstar community, but thought I would ask here first. I recently received a DINAH and have installed Asterisk. The DINAH is connected to an ICOM IC-7100 and appears to be working. I had planned to use a Yaesu FT1XDR as the HT for communicating with the node as it has a front panel keypad for sending DTMF easily. For some reason, I cannot reliably decode DTMF commands using the FT1. When I try using an Icom ID-51PLUS2, the received DTMF is decoded flawlessly. I have tried to replicate the DTMF transmission settings of the two radios and no matter what, the only reliable character decoded by the node is an '8'. '*' and '#' is intermittent decode along with all other characters. Is there a method of 'optimizing' DTMF decoding within asterisk? Who knows, maybe this is a Yaesu to Icom thing. If this doesn't work, I pull by FT-857D from the car and try it just to see if the issue is the radio connected to DINAH or something else. Thanks, Chuck, K6CES

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.

Staring at the schematic I'm not sure what the intention of JP1 is? I would like to use the discriminator output of the radio, pin 4 on mDin6 connector, but the only way I think that is possible is to make a cable that routes pin 4 on the radio side to pin 5 on the DINAH side. Could someone who has enabled 9600 baud on DINAH explain how they did it? I've been using 9600 baud packet with another sound card and config the radio to use 9600 baud data for both 1200 & 9600 data rates. Doing this you can easily switch between 1200/9600 baud packet by just changing the data rate within direwolf config file. I received my DINAH kit yesterday and put it together with no problems. The instructions are VERY good. Had it running 1200 baud packet straight way using a Raspberry Pi. Very satisfying. Thanks, /Basil n7nix
