TNC Not Transmit

dusty.nr4n@...
 

I have a TM-D710A in a fixed station. I hadn't exercised the APRS in a while and decided to transmit a few packets. I hit BCON and no TX. I'm not using a GPS and have it set to use a single location. Nothing has changed in my setup or memories. I decided to try Winlink. Winlink will connect to the radio and put it in packet mode. When I tell it to connect... Nothing. Eventually it times out. I figure... the TNC must have gotten SNAFU'd and did a FULL reset. I put my callsign and SSID in, did minimum to get it to beacon APRS... Nothing. Yes... the squelch is closed... no 'busy' on either band. So I set it to beacon every 3 min. I turn the tx beep on so I will hear it beacon and I hear the beep but no "on air" TX. It beeps every three minutes faithfully but no TX.  So... I try to manually get the TNC to transmit the only way I know how.. I get PuTTY going and connect. I'm able to send and receive commands to the TNC, I'm able to receive packets and read them with PuTTY. The TNC is working. When I send the C command and a callsign I know is on the air, nothing... no tx. It eventually times out. 

I'm about to pull my hair out. Audio in and out is fine. No problem using it as an FM radio through repeaters. Audio reports are fine. I pulled the nearly dead battery out of the head and ordered a new one. Left it over night and put the old one  in the next day. That did not fix it. I even reinstalled the firmware for the head unit. That required a full reset again. It just will not TX from the TNC. Even tried to send an APRS message and nothing. I have tried three different cables to connect the head to the radio.. nope.

Can the head unit's battery being very flat (only keeps clock a couple of minutes after turning it off) cause this behavior? I mentioned I have new ones on order but can't test yet as they won't be here for a few days. Does anyone else know what else to try? I am not the first owner and opening it up, the only thing that looks obvious is that it has been modded for MARS/CAP. I cannot see the board that has the jacks for the mic and the control head without pulling the main board which I'm hesitant to do since it looks pretty pristine. I have posted this on the Facebook group so please ignore me if you have read all this before... thanks

Frank,
Was ISS in APRS Mode?  ISS was doing Slow Scan TV recently, with APRS off, I believe.

For Lynn, I believe Frank  N3FLR was using the TM-D700 Radio with internal TNC to monitor 145.825 MHz on receive and 144,390  MHz as transmit (odd split pair in the frequency memory), with digipeater ON.

Saved as a PM, or Program Mode in that separate memory, select PM and a QSY to the special Frequency odd-split memory as above, and selecting digipeater ON should allow repeating packets from ISS to local Terrestrial network, but to what end escapes me.

Re: TMD710A memory question

Bill Mader
 

The manual is the best place to start!  I own several TM-D710A's.  I have programmed them into the ten possible banks for the entire State of New Mexico plus a bit of surrounding States I am likely to visit.  I broke NM into nine geographical areas and saved the tenth bank for APRS (channel 999) plus many other non-ham frequencies I might want to monitor in contingencies.  I can scan any of the ten groups on one "side" while I use APRS on the other.

You cannot listen to any VHF frequency on one side while APRS is transmitting.  That should be obvious since any two 2m frequencies are too close together.  However, APRS only transmits when "necessary" and most often infrequently.  If you make a turn and the radio recognizes that turn, It will send a new beacon.  If you're listening on 2m on another frequency, you'll lose that tiny piece of information while the other side sends the new APRS beacon.

The key is to RTFM!  You may need to do that.  "Help" from others may or may not be helpful although for the most part it is, especially in these groups.  Other sites have lots of information is that is simply false.  Such as it is in our scientific avocation where opinions of myths outnumber facts.

Re: TMD710A memory question

J K
 

Rich is right, check the manual. Here's an excerpt from user manual concerning PM, not to be confused with the frequency memories.
-------------------------------------------------------------
Programmable Memory (PM) stores virtually all settings currently set on the transceiver. This transceiver provides 5 PM channels to
store 5 sets of transceiver configurations. Later, you can quickly recall any one of these channels, depending on the operations you
have in mind or the operating environment.
----------------------------------------------------------------------------
Pay particular attention to the user manual where it lists specific items that are NOT stored in PM's.


Re: TMD710A memory question

Sorry, no Banks per Yaesu on the 710 line, but you can program by memory # and then scan by 100, 200, 300 etc.

Read the manual for specifics

check out the manual. The tm-d710ga has 5 programmable memories. each memory can hold 5 frequencies...

Re: Best Way to Change Configurations TM-D710G?

I figured I was missing something! Thanks.

Now that I have separate MCP-6 files, is there a way to "combine" them or do I need to manually configure each set-up and store via PM?

Bret/N4SRN


Re: Best Way to Change Configurations TM-D710G?

Jeff Lehman, N8ACL <n8acl@...>
 

LOL what Mike said….

I have 4 PM’s set up in my 700 - 2 for APRS around town (one for day mode at full screen brightness and one for night mode with a dimmed screen brightness) nd 2 for APRS when I travel (same modes). 

Program what frequencies you need and then configure the radio for use with Winlink and save it to a PM. Then turn off the PM and configure for APRS and see to the next PM. Make sure that is off and set it up for your next configuration and save to a PM.

That way when you need Winlink, turn that PM on and the radio configures itself. Need APRS? Turn on that PM and the radio configures it self. 

It doesn’t;t change the channel programming (that can be done front panel or via the software), but that is why you would want to store all the frequencies you might need.

Re: D700A help with ribbon cable connector

Joseph LaFerla
 

HI Leo

After a very long wait looking for part numbers and parts, I have finally been able to get the connector soldered in place.  I first contacted Kenwood USA who gave me the part number and that I could get it through East Coast Transistor and Parts. I sent the radio to a local repair shop since the connector is smd and very tiny.  The repair shop guy tells me that, once the connector was soldered in, the radio immediately powered up and the tnc now works.  So it would seem that something in the bootloader goes around looking for each component and will hang until it finds everything.  Although it took much longer, especially since I live in Canada, I preferred to wait until the exact replacement part was received rather than getting one from Digikey.  I actually bought two connectors and will keep one as spare just in case.

Thanks for your help and suggestions to all who provided input.
