This begs the question in my mind whether the SA818-prog script could be adapted to have an "unattended" mode, so that it could be reused for this type of programmatic call. |

Channel changing script
开云体育I cobbled together a simple script to change frequencies faster on the SHARI pi hat using DTMF. ? I had a need to be able to change it on the fly as some areas I frequent have interference and remoting into it and stepping through the SA818-prog script can be a pain. ? This is python2 to support hamvoip. ? In rpt.conf under functions you can add: ? C01=cmd,/etc/asterisk/local/channel.sh --channel 1 C02=cmd,/etc/asterisk/local/channel.sh --channel 2 C03=cmd,/etc/asterisk/local/channel.sh --channel 3 ? I have it set the filters off and pre/deemph on. Volume set to 7. Reverse burst on. ? Channel format is as follows: spacing,FreqTx,FreqRx,tx_ctcss,squelch,rx_ctcss ? So for 438.2500 simplex with a tone of 123.0(encoding and decoding), squelch set at 4, and 25khz channel spacing: 1: "AT+DMOSETGROUP=1,438.2500,438.2500,0018,4,0018\r\n", ? Tone chart:
? ? ? ? #!/usr/bin/python2 ? import argparse import time import serial ? def main(): ??? parser = argparse.ArgumentParser(description='Send text string through serial port') ??? parser.add_argument('--channel', type=int, help='Channel number (1-3 for ham)') ??? args = parser.parse_args() ? ??? channel_map = { ??????? 1: "AT+DMOSETGROUP=1,438.2500,438.2500,0018,4,0018\r\n", ??????? 2: "AT+DMOSETGROUP=1,438.5000,438.5000,0018,4,0018\r\n", ??????? 3: "AT+DMOSETGROUP=1,438.7500,438.7500,0018,4,0018\r\n", ? ??? } ? ??? if args.channel not in channel_map: ??????? raise ValueError("Invalid channel number. Must be either 1 to 3.") ??? text = channel_map[args.channel] ? ??? ser = serial.Serial('/dev/ttyAMA0', baudrate=9600, timeout=1) ??? ser.write(text.encode()) ??? ser.write("AT+DMOSETVOLUME=7\r\n".encode()) ??? time.sleep(1) ??? ser.write("AT+SETTAIL=1\r\n".encode()) ??? time.sleep(1) ??? ser.write("AT+SETFILTER=0,1,1\r\n".encode()) ??? ser.close() ? if __name__ == '__main__': ??? main() ? ? ?

Re: Multiple DTFM characters detected from a single key press
It can happen to any radio. MY oldest FT60 is more than 12y old and in the past few months one of the keys has been acting finnicky. I probably need to pull it apart and do a cleaning. FT60 was well constructed. That older unit has been dropped and bounced around many times and it's still doing very well.

Re: Libre SBC, and also AURSINC Shari
This has been my experience as well, but I have only had a few hours of free time to work with it. I can say that the Libre looks like it would make a fine MMDVM for DMR etc, but it sure has a bad allergy to dahdi.
But the ham community is remarkably ingenuitive, as evidenced by Allstar and the Shari itself. It wouldn't surprise me one bit if the next big digital mode to come out involves teleportation, so surely, someone has dahdi running on a le potato. :) |

Re: Multiple DTFM characters detected from a single key press
Download this file from the Files section of this group.
/g/SHARI/files/Setting%20the%20RX%20Level%20in%20HamVOIP%20Allstar.pdf It will allow you to see your DTMF levels when setting the RX level in simpleusb.? In addition to setting the correct level, make sure the level is about the same for all the DTMF characters. |

Shari Pixx No serial communication with sa818
I'm trying to reprogram the SA818 on my Pi3U. After launching SA818-prog, it says "Testing serial communications" then, "No Serial Communication with the SA818 module"
I've never had issues with SA818 before. Any ideas? <X><

Re: Multiple DTFM characters detected from a single key press
I'm thinking that either the VX-6 keypad is extremely sensitive or you are inadvertently sending tones more than once. The fact that it works well with Supermon shows it's likely a keypad issue. I have sent tones from 3 different Yaesu FT60s without issue.
