Re: Optimizing DTMF Tone Decode

Hi Steve,

The FT-857D is setup for 1200 bps packet. ?I use the same radio with a kantronics KPC3+ using the 6-pin DIN connector.


BTW, the DIN cable supplied with DINAH has a connector mold that does not allow complete insertion into the FT-857D DIN connector. ?The rectangular top edge buts up against the edge of the FT-857D case and the protrusion between the DIN and CAT connector, but I do not believe that is the issue. ?Once I solve this issue, I will procure a DIN-to-DIN cable that has round connector overmold in case I take the FT-857D portable. ?It is my main field radio and I want to ensure I get full insertion of the connector.

I will keep experimenting. ?I am certain this is operator error.

Hi Chuck,

Good to hear my RX level setup process worked for you.

You need to set the FT-857D for packet operation to use it as the node radio.? Look at pages 65 and 66 of the manual.

Hi Steve,

Following your document, I have been able to get reliable decodes from an ID51Plus and the FT1XDR.? Additionally, I can get reliable decodes from my FT-857D when my Icom IC-7100 is the node radio.

If I attempt to make my FT-857D the node radio, no decodes are happening at all.? With the FT-857D as the node radio, the callsign and IP address are announced from the radio at asterisk startup, so I know transmit occurs.? However, on receive I can see the S meter on the FT-857D indicate S9+, but I do not get any decodes nor is the courtesy tone transmitted.

I will play around some more before I try to make connections to other nodes and ensuring audio quality is good.

Thank you for pointing me in the right direction.? As a newbie to asterisk, I had no clue what the issue may be.

Thank you Steve.

I will give this a try.

Hi Chuck,

I have uploaded a short document to the files section describing the method I use to set the RX level in HamVOIP Allstar to optimize DTMF decoding.? Also, for DINAH, be sure that de-emphasis is turned off and that the plfilter is set to "yes".

Optimizing DTMF Tone Decode

Chuck Smith (K6CES)
 

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


Re: Issues connecting with Dinah Interface - SOLVED

 

Thank you again Steve for getting me straightened?out. I was able to connect to a friend in Virginia and the audio quality was excellent.

I worked with Les via a phone call to get his DINAH working.? He had a couple settings wrong.? I will be rewriting the DINAH setup procedure in the near future to make it more like the SHARI setup procedure which has more pictures in it.? Also I will include the COS LED setup as part of the procedure instead of a separate document.

Issues connecting with Dinah Interface - SOLVED

 

I recently purchased a Dinah interface to use to connect my RPi3 to a radio with a data jack. I originally connected to an old Icom 207H of which I have two of them and no luck with either of them In the mean time I got another 6pin mini din cable thinking maybe the one sent with the unit may have been bad. However no luck with the new cable. I connected it to? a Kenwood V71 I have and made sure the side of the radio I selected was correct for data. It transmits my callsign and? myi.p adddress on bootup and Id's once every hour. But I cannot connect to another node. The lights on the back do not light up. I even tried a different USB port on the Pi to no avail. Is there some configuration in the programming that I missed to get the DINAH to talk to the Pi.? I am at a lost what to? do with it.
