Downloading Track Logs

Joshua KJ7LVZ
 

Anyone have an idea how to get the saved track logs and marked waypoints off a D710G?  I have and RT cable that I use for the TNC and programming.  
Also, I use a Macbook.  If there is a Linux software option, that's my second choice.  Last ditch effort is Windows.

I had to replace the internal battery inside. It is like a thin cap standing on its end. It brought mine back to life except for the year won’t change.

Re: Prog 115200

Jeff
 

A few years ago I had this exact problem. One day I turned on my D700 and got the Prog 115200 message on the display. I could not resolve it and sent the radio to the (now closed) authorized repair center in Virginia. The radio came back and worked maybe for a day, and the message returned. I sold the radio as-is to another Ham and bought a new D710. I never got feedback on what any resolution might be, but at the time read something about it possibly being a issue with a chip in the control head. Sorry I cannot provide more info.

TM-D710a will not transmit or receive

Earl_NV6E
 

A few weeks ago I replaced the 4 filters in my TM-D710A and all worked just fine until the other day.

Now, when I turn on the radio I get the usual 2 beeps then another beep, which I had never heard before.  The radio will not transmit, just get a beep, followed by another beep.  This happens on 2m and 440 both.  Will not receive a signal and most of the time the "busy" indicator is on no matter where the squelch is set.

Hello, I have a kenwood tm-v700, one afternoon, I turned it off working perfectly, but in the morning of the next day, I could not turn it on, after several attempts, it worked with the following message, prog 115200, and by pressing the middle key On the left, it appears not installed, I can't go from there, I have tried with the reset button without success, Has this happened to someone else? there's a solution? Thank you


D710a Operating Panel Firmware Update

Ryan - K9NBG
 

I just got a Kenwood D710a that had firmware 2.10 installed, figured I would go ahead and update it since the MCP software was complaining.
Firmware updated fine, did a full reset, but when i try to update the panel I get an error 'Could not detect the operating panel'
I've tried to reset the VFO and full memory, reboot computer, different com speeds, each time I can't update the panel firmware. Anyone else seen that or have any ideas?


Re: Digipeating MY CALLSIGN TH-D74a to TM-D710G

Dave, W8AAS
 

The suggested path is not quite right.  It would have to begin with the call of the digipeater, in your case N4SRN-1.  I think that would work for your D74, but would also digipeat any non-specific paths the D710 hears (relay, WIDE, etc.)  There are a couple of other possibilities:
 - Use the path TEMPn-N on your D74 (choosing n and N as you would for a WIDE path, based on your desired coverage).  This would let anyone using a TEMP path be digipeated, so you might get a few other hikers, but I think not many people are aware of TEMP.
 - Look at the NETWORK setting.  If you pick a unique ALTNET for your two radios, I think that would keep your digipeater private to you.  However, I'm not sure how this would affect further digipeats beyond your D710; this needs some research in the manual.

Dave, W8AAS


Re: Digipeating MY CALLSIGN TH-D74a to TM-D710G

Charles Jessee
 

Digipeat only "me" as entered in the MY CALLSIGN item, rather than anyone who hits my D710G.

I learned elsewhere that the D710G defaults to UIFLOOD TEMPn-N so that aspect appears already addressed.


Re: Digipeating MY CALLSIGN TH-D74a to TM-D710G

Joshua KJ7LVZ
 

What do you mean by digipeat your callsign only?  You don't want it to digipeat your position?  Or rather, you don't want it to digipeat others' callsigns and positions?

Joshua,

I agree it's a shame that APRS messaging isn't more widely used. I suppose it the chicken and the egg problem since most APRS radios are a nightmare to try and message through. Perhaps the next gen radios will feature built in BT TNC's for easier interfacing.

We have a handful here that message somewhat and I was recently contacted via APRS messaging by a ham in Turkey.

Thank was neat!

Have a good one.

Hi Joshua,

I didn't follow this real close but when I saw you mention the TMV71 it make me take note.

I too had some surprises when trying to connect to the TNC in my 710. I have since put the 710 in my daily driver and use the TMV71 in the shack for repeaters and APRS.

I have been quite happy using a Mobilinkd TNC (v2) with APRSdroid on my Galaxy S20 Ultra. (You could also use a cheap tablet off amazon) It works quite well and you can get the cable to plug it right into the audio port on the back of the radio from Mobilinkd.

This isn't a perfect solution for a digipeater or similar but it's great for letting my friends know I'm on the air and what frequency I'm on ATM.

Just thought I'd mention it.

Have a good one.

Re: TNC Quirks

Hello Joshua,

One was a Baofeng, one was a Retevis.  I'm only a little surprised since I have a Baofeng setup as a bi-directional iGate and it functions perfectly in that role. 

I could go on and one here about the issues with many of these cheap chinese radios be it their slow and/or inconsistent key up times (requires a high TXDELAY), their slow or inconsistent TX to RX time, inconsistent receiver issues, poor transmission signal quality, etc. and ultimately... all of these issues changing from one radio to the next (little quality from one radio to the next off their production line).  It sounds like you might have gotten a "good" radio but many other people get something less.  You will be far better served buying an older used radio from a decent company than these radios when it comes to consistent packet operation.


I don't see a TNC firmware update on Kenwood's software update page, just the main body and the control head updates.  Also, the release notes don't mention anything consequential.  However, both my main body and control head are two software versions behind.  I'll have to use my work computer to handle the update since Kenwood's update software only works on Windows. 

I looked as well.  If you look at the D710A pages, you can see some TNC firmware updates but I guess the D710G hasn't needed any updates yet.


The Mobilinkd style TNC is a TNC I built using Mobilinkd's schematics and instructions.  It is an Atmel 328P communicating with an HC-05 bluetooth serial adapter exactly like the Mobilinkd.  I have a few photos of building it here: https://joshuajayg.smugmug.com/Tech/Ham/TNC/

Gotcha.  Those setups really are pretty impressive in how they do so much but you're still sacrificing 1200bps AFSK decode rates compared to say Direwolf, a Kantronics KPC3, UZ7HO soundmodem, etc.  It's all a compromise though.. it get it and these Mobilinkd units aren't bad by any means.


Also, I haven't found that Direwolf has a front end that will emulate a normal TNC like BPQ's Simple KISS does.  If you know of a way it would work, I'm willing to give it a try. 

It all depends on what you're looking to do.  Why do you want to connect to a "classic TNC" serial terminal interface?  Are you looking to create connected mode sessions to remote stations?  Are you looking to send unconnected (unproto) packets?  You can do all of these with Linux's native AX.25 support and either included or third party packet applications with just a KISS TNC.  BPQ32 can do all these things with a KISS TNC w/o the TNC2 UI interface, JNOS can natively do these things, Qtterm + Direwolf's AGW interface can do these things, etc.  I'm personally biased to use LInpac + Linux's AX.25 stack as I maintain that code ( https://sourceforge.net/projects/linpac/ ).


But in reality, I don't know of a reason my D710G needs to receive an incoming connection request.  I imagine I will always initiate the request FROM the 710.

There are packet communities out there that run KB2KB packet stations where people leave packet messages on remote TNCs be it KPC3s, PK232s, D710s, etc.  It's a simple, old school yet effective interface.  The D710 makes this one step easier as the radio and TNC are in one (more expensive) package.  If you're willing to work a bit for it, buying say a Kenwood V71 and connecting it up to say a Raspberry Pi Zero will yield you a solution with a substantially better TNC and a lot more flexibility with what you can do with the setup.  It can be all self-contained, it can offer packet services via Wifi or Bluetooth, etc.  Sky is the limit.

That's strange to hear it wouldn't accept a connection from the same callsign but a different SSID.  That *should* work.  Are you sure you're running the newest version of the D710 TNC firmware?

When you say "Mobilinkd style TNC", is this some simple PIC based Bell 202 TNC?  Those can work but their performance isn't all that great.  Since you're a Mac user, consider trying out Direwolf.  It runs natively on the Mac and it's performance is practically unbeaten by any other hardware or software TNC out there:

   https://github.com/wb2osz/direwolf

This also works very well on Linux with hardware like Raspberry Pis, etc.  I have a document for that too:  :-)

Anyway..that's all food for future though.  Glad to hear you got things working!
