Re: Cannot transmit with D700a using TNC PKT

Don Poaps
 

Are you using Linux or Windows?

 

Have you setup the menu to use 1200 B? Are you trying this on your voice side of the radio? That could be one reason why it won’t PTT.

Subject: [TMD700A] Cannot transmit with D700a using TNC PKT

 

I am trying to use my d700a with yaac or another aprs program to receive and transmit aprs packets.  Everything is set correctly and I can receive packets correctly.  However I cannot transmit.  The software is set up correctly but my beacon does not get transmitted, neither can I transmit if I hit the transmit button.  Is there some special setting that I have to set in my radio to enable transmission of packets?  This is only apparently a problem if I use the built-in tnc because if I connect an external tnc everything works fine. 

I would appreciate any help to get me going.  Thanks in advance.

Correction Dave, you were right.  closing  the squelch did it and enabled me to transmit!!  Thanks and what a simple thing to do!!!

HI Dave

 

I tried to close the squelch but no luck.  Still cannot transmit.  Should the packet TXC setting be manual or auto?

When I can't transmit packets, it is usually because I left the squelch open and the DCD setting prevents transmission.  It thinks the channel is busy.

I understand 
When you want to use the TM-D700 internal TNC, you must switch from APRS mode to PKT mode on the radio.
Then power off the radio and controlling computer, connect the data cable to both, then power up the computer.
Power up the radio as you load the program of choice, preferably a simple terminal program.
The internal TNC might not be in Command mode, so type and send <CTRL C> to TNC to ensure it is in command mode.
Type DISPlay command
. The TNC should respond with the TNC Command list and current settings for each command,
   Type MYCall with a space then your Callsign followed with return key to enter
FYI after this, send the letter "k" to switch TNC to Converse mode and send "test" while watching radio display
for transmit.
If this does not work (radio transmits), you may have a setting on serial flow control wrong in your computer, or a bad cable.

If you connect to the TNC via the COMMAND interface, can you successfully transmit a BEACON or other packet?

I am curious who Powerwerx deals with, cause I baught a wouxon and cable and it worked great for several yrs, then suddenly it is no longer recognised. I have since bought a new cable, but feel rather swindled and cheated that a cable I bought from a reputable source turns out to be garbage, and no we arent offered a proper free replacement, no we are required to spend more.
 I have spoken with legal counsil, and there is a possibility of suit, as this seems to be a prolofic problem.

HI David

 

Actually no, I have a real com port but I have had my share of troubles with the prolific chip.  I have two usb serial adapters to run my home automation software on my raspberry pi but otherwise have tried to steer clear of them if possible.  I still like “real” com ports.

Since very few computers have real RS-232 ports any more, I'm assuming you're using some kind of USB to RS-232 adapter.   If so, here's an anomaly I ran into a few weeks ago.

I have such an adapter, a Trendnet TU-9S if I remember right, which has the infamous Prolific chip set that everyone rags on and says doesn't work and so forth.   So I attempt to program in TS-2000 after a full reset a few weeks ago, and in spite of the setup being exactly the same as it was previously, I couldn't communicate with the TS-2000.   I tried lots of stuff, including putting a new TU-9s into the system.   Still wouldn't work.

Then I retrieved the cable from RT-systems that came with their programming software, put it in the line, and things started working.   I was able to program the TS-2000 with all the info I had saved previously.

Why did the old Prolific-based USB to RS-232 adapter stop working?   I can only speculate that the bunches of updates that Windows is continually receiving somehow messed with the USB communications.   They keep updating Win 10, and this and that stop working or work differently, it just keeps happening.   That might be the problem.

I wasn't trying to use the Prolific interface with my TMD700, it was in the programming cable for my Wouxon radios.

I have successfully used a USB-RS232 dongle that provides all the control lines with my D700 and the Kenwood software. I don't know who made the dongle, however, I don't see any markings on it.

Sorry I can't be of more help.

I ran into the Prolific problem with an older Wouxon programming cable I

Googling told me it was due to counterfeit Prolific boards that some

Re: Cannot connect tmd700a with yaac

Hi Ron

 

Yes all this is correctly set up.  In discussions with yaac’s author, it appears that yaac runs a validation test on startup and does not enable the port unless the test is passed.  It has something to do since kenwoods use hardware flow control.  I am still struggling with this and will post my results as I can.

Re: Cannot connect tmd700a with yaac

Randy Allen
 

I assume since you mentioned the hardware flow control of the com port, you also ensured that the com port is also set to 9600 to match the radio and YAAC ?  I mention it as I've messed that up in the past.

Is there a possibility of something else is already using the com port?

And going back to basics, YAAC is trying to open the com port the cable is connected to? 

(I'd be embarrassed to tell how many times I missed this when trouble shooting.  I'm sure that Murphy comes in behind me to change settings when I'm not looking).

What operating system are you using?

Hope this helps

Have had a Yaesu FTM-350AR for years and decided to come back to Kenwood.  Now I have the Kenwood TM-D710G and the radio seems to be great except for the display.
Have not found a way to make the Memory Name larger and the Frequency read out smaller.  With mobile operations it is easier to go through the name vs frequency.  Would think that Kenwood could fix this with a firmware update, if they want to stay ahead of competitors.   Am I missing something in manual or some magic key combination?
