DORJI DRA818V



Has anyone any experience with this little transceiver module?  DORJI DRA818V.


Specifically, interfacing with the T3-Mini.

Script autoACK and flag condition problem [1 Attachment]

[Attachment(s) from ve2wfn <at> yahoo.ca [tracker2] included below]

Hi,


 
I made a script that I adapted from codes examples of James VE6SRV. I uses analog inputs for a door intrusion monitoring.  (5V, 50units = Door Open, on input 0-20V of the OT3m)


As the OT3m will be used in the north, the site is powered by solar panels, all amp must be saved especially in fall and winter periods.  The other constraint is that it's very difficult to receive packets (APRS messages) from the south, the traffic goes down well to Igates, but it works much less well in reverse.



So in these cases, the radio is only open for transmissions, controlled by the Power control command of OT3m (PS output drive a SSR). A manual remote ACK Alarm (Macro ALARMACK) isn't possible in this cases.


My solution is to reset alarms automatically between 30 or 60 minutes, with a block of code for this.

I do my code, but in my tests, I have a problem when the second incrusion (door open = 5V) occurs.


the first intrusion sending the message immediatly when I put Analog 1 to 5v. But, after the Flag reset period, if a do a second intrusion, nothing, the script doesn't react to this, no message sent What is my code problem?


my script:

----------------------------------------------------------------

On Second
  Increment Counter 1
  If Counter 1 > 300                           ;5 minutes only for my test
    Clear Flags 00000000
    PrintA " Flag Reset "
    Set Counter 1 = 0
  End Block
End Block
Exec "ANALOG 1 IN"
If Result > 40
  If Flags 0xxxxxxx
    Exec "SEND EMAIL xxxx <at> hamradio.com Door Open"
    Set Flags 10000000
  End Block
End Block



----------------------------------------


Else, it's normal in the script Editor, I am not able to do a  «don't care» condition with «set flags» or «Toggle flags», only with «If flags» ...  even if the boxes are gray, it puts "0", no a "x"   ?  (view flag.jpg)



thank you for your help!

Weather trame & 1WIREWX command



hi,


just to be sure, It isn't clear in the manual, but when the command 1WIREWX is ON, automatically the OT3 transmits a weather trame has all the TX Interval (Transmit Every x sec) like a normal beacon? 


No need to do a script to send the BEACON W every X minutes. The OT3 did this automatically by activating this 1WIREWX command, right?


I use it with a DS18S20

OT3m Digipeating - Garbled oitput



Hi Group


I have an OT3m and I have had it connected it to two different radios in the past few weeks to see if there is any difference in performance, as I have been experiencing serve garbled output from the OT3m when used as a digipeater. Let's face it, it does digipeat, but the output of the characters is so bad, that it might as well not even peat anything.


I have checked the cable for and that seems to be good. I have tried adjusting the levels of the audio thru the config program (which I have connected via USB interface).


I have had assistance from a fellow ham with the setup in resolving the problem. He too has reported difficulty in getting the settings right to prevent the output being poor.


Am I just to persist on getting the audio levels right or could there be another issue present that I am overlooking?

I have the jumpers set for the type of radio being used (208H or TM8110. I will be trying FT7900R in a few weeks to see if any difference) 

I have the latest firmware installed - 2013 version


Any assistance would be greatly appreciated, especially those with similar experience in how you got your OT3m working after similar problems.


Cheers

Dave

SSR power Control on T3-Mini



hi,

   My next step with my T3-Mini is fed by power control (GP6 pin) my radio (Radio Shack HTX-242) with a Fotek SSR-40 DC-DC.

What is the best way to drive the input of the SSR?

T3-Mini power starting problem



hi,

 
If I start my mini-t3 only with a 12v (power supply) on the Vin input (nothing on the USB port), it seems to have a problem ... It starts with the normal short LEDs flashing sequence ... but nothing after..., no beacon TX . But at all 30 seconds the red LED will flash shortly.

I did another test, powered with the Vin 12V and 120V to USB-5V adapter  on the USB port .. Same problem ...


The only way to transmit normally, it's to connect a USB cable from the PC and  only open OTWINCFG.exe and when I leave the software, it normally starts and do these transmissions to the interval set.

A idea for me ?


thank's

question on scs tracker audio input levels



Is there a way to either adjust the tracker input level, or the audio output level of the ICOM718?
I ask because many times, I can hear a signal clearly, but the tracker DCD light remains off.
I am getting a sense that the audio level might be insufficient to drive the SCS input at times.
thanks!

Adafruit GPS



Does anyone have any experience using an Adafruit ultimate GPS breakout V3 with there open tracker? I have mine wired and connected, but it will not transmit a beacon. I know the GPS has acquired a fix from its on board LED. 

If I check the don't require GPS fix box, it will beacon as normal.

T3-135 and DR-06T Digi



I just bought 2 of the t3-135s and have them installed in my 135 and 06T. I'd like to create a Digi/Igate on 6 meters with the 06T. Has anyone done this ??? Can someone share a config file with the appropriate setup ? I want to try and get going something like they're doing on the east coast here in the mountainous area in north east Nevada.  Thanks,  Brian  nb9e

Bletooth on the T3 to use with APRSdroid



I found a bluetooth dongle shown on the T3 facebook page back over a year ago and wanted to see if I could get my T3 to work on bluetooth so I might use it on the ARRSdroid app on my droid tablet. I could not find any referance or place to purchase the dongle on Argent's web page. Is this unit available and where might one be purchased.


Has anyone used the T3 with the APRSdroid app? I have purchased the AP510 portable tracker and it works great with the APRSdroid program on my Nexus 7 tablet but I would like more power as the 1 watt does not quite make it happen in the rural area where I live.


Thanks


Mike
