Re: D710 repetitive restarting

David Ranch
 


Few things come to mind:

  - pop out the fuses in each of the holders, squeeze the contact holders together a bit and put the fuses back in
  - when you turn the radio on, start tapping the TNC button as soon as to get it to turn off

Now.. does the radio stay on?  Try setting the radio to low power and transmit.  Does it reset?  Try medium and then high power tests too.

As the group co-owner, I can confirm the group is for both radios.

Thanks for your help...

And last time I checked this group was for BOTH the d700 and D710. At least that is what it shows on the group home page.

Re: D710 Inhibit APRS beacon

Randy Allen
 

Are you talking D710 (per the subject line) or D700 (this being a D700 group)?

For the D710:
Menu 601, set DCD Sense to "D or RxD Band".

Using the MCP-2A software, look under <Menu>, <APRS/NAVITRA>, <Internal TNC>, <DCD Sense>, "D or RxD Band"

For the D700:
Menu 1-6-2, <TNC>,<DCD Sense>, "A and B Bands"

Using the MCP-D700 software: <Radio Menu 2>, <DCD sense>, "A"and "B" bands

Hope this helps

Re: TM- Operation sans Head

Jim Nagle
 

One software package I previously used was the D700 SunSat SW

http://www.qsl.net/g6odt/d700.html

 


Re: TM- Operation sans Head

noskosteve
 

 

Yes.  The D700 can be programmed and operated via computer-serial port.  It can also be operated WITHOUT a control head via the serial port.    I think someone else made a computer mirrored control head, but don't recall who/where...  I played around with a control hear replicadisplay also, but only started setting up the display format and didn't couple it to the commands.

 

It can also send and receive APRS messaged via computer.   I did some APRS messages and also email testing though the EMAIL server, but it's not in the released workbook. 

 I also started adding the ability to do WinLink email, but never completed the macros.   Winkink takes more than one APRS message to send an email and you must ping the Winlink-APRS server to receive your email since ordinary email can't cause a ham transmitter to transmit.

 

If anyone wants to play with the macros, the workbook on my site is open source.  If you are serious about doing some programming for email, I'll even send you what I can find with the email testing stuff --- whatever it is -- I don't recall much off the top of my head but could get you pointed in the right direction...perhaps.  It's been a while since I played with it. but I do try to comment my code well.

K9DCI - Amateur Radio Control 

 

It wouldn't be too difficult to add a macro to send the 35 CRs to turn it on (or off) to my existing code, then use the spreadsheed to use the radio.  It is not a control head look-alike interface, however.  you would enter a freq, then click on it or another button to tune there.

 

The following is the contents of a Jan 2011 document that I surely must have uploaded into the Files area, or at least posted here: 

 

D700 operates Without Control Head.docx

 

The following applies WITH or WITHOUT the Control Head connected.

  You can turn on the D700 radio from the serial port. The command is simple ASCII "PS 1" no quotes, end with a Carriage Return (CR) character. In Hex this is &h50 &h53 &h20 &h31 &h0D.

HOWEVER ONE WON"T DO IT.

  It appears to be an issue of having serial port activity for some time period because of the following observations.  I never traced out the schematic to see if there was something between the serial port and power circuitry to verify this assumption.

 

  Typing manually with Hyperterm, it takes 2 or 3 PS 1 commands.

  Testing at 9600 baud, it takes about 35 characters to wake up the processor to then accept the command.

  I found that sending 35 or more CRs followed by the PS 1 CR works well. In HEX this is 35 &h0D's then &h50 &h53 &h20 &h31 &h0D.  The CRs dont do anyting to confuse the processor because it ignores them until it gets some other characters that it tries to interpret as a command.

 

  Other characters work, but if you have more than 35 before the PS 1 command, the radio will balk at the invalid command the characters represent and respond with "?". The number 35 seems to be slightly different for different characters. Sending complete PS 1 commands takes 8 of them which is 36 characters before the final command. Sending from 32 to 34 CRs in the "prefix" will turn on the radio, but it responds with "?". This is not recommended, use = or > 35.

 

  I did find some variations from the 35 character "prefix" that would both power up the radio and respond with a "?". Then, subsequently sending any other command resulted in receiving a PS 1 from the radio. It has to get that ) the invalid commands) out of it's system, so to speak.

 

  When the radio powers up, it responds with the same thing as the command, namely "PS 1".

 

  I also found some variations (usially 2 or 3 less characters) that did NOT power up the radio, but responded with the "?".

 

  Less than about 30 or 31 characters of prefix has no effect (no response from radio).

 

  I did not do any exhaustive testing of other commands once powered up sans head, but a few worked normally, so It's a safe bet that everything that can normally be done from the serial port also works and pretty much normal radio control is possible. I know that there are some things that can only be done with the Control Head, however, I do not have a complete list compiled.

 

  I also have a free for the download Excel spreadsheet that does control and memories including ALL PMs. I'll have to add the power up sequence and basic volume and squelch capability in the future.

Re: D710 loss of RX sensitivity

Dan Huber
 

Yes - the A-band on my D710 is silent for wide FM.  If I tune it to the local weather service and switch to narrow FM, I can receive it.

There is a YouTube video explaining what happens - filters going bad.  Sent email to Kenwood - they will fix under warranty even if the radio is out of warranty.

My D710 recently has lost it's RX sensitivity.  I have swapped the antenna out (on the NMO side, so it used the same cable and connectors), and it did not change.  The SWR is the same as it always has been about 1.15:1.  At our club meeting last night, two vehicles side by side, mine had static on the local repeater while all the others were full quieting.  I have not ruled out the coax yet, but has anyone else experienced this?

Re: D710: APRS and 4RRX1T? = mystery solved!

scotchmandr@...
 

Honestly, this is weird. As stated, I am doing APRS and not AX25 Packet. On the Radio ONLY (no software or PC). This is entirely on both the D710 and a D72A. Different SSIDs same weird String prefix. Other D700/710 owners have similar Strings. They change "occassionally" if one looks at enough raw packets. Bob WB4APR suggested checking the unproto thinking the same as you did. Well, IT And ALTNET are both blank on both radios. I am not running AX.25 Packet nor PC Software for APRS. IT is ONLY Radios!

No one seems to know where this comes from and I am not the only one. Check APRS.fi and study the raw packets of other Kenwood users. Yaesu FTM-400 does something similar.

My Argent Opentracker has a fixed String prefixing all its packets. APOTU0 - and it does not change.
Most packets start with CQ but these do not.

IT seems to have many of you puzzled as well! Check your own packets on APRS.FI and see if it is a small group or all of us? I have also emailed Kenwood.

How did this even start? Because,
coincidentally; both myself and a local igate decided to switch to 146.825 and listen for the ISS. I emailed him when I noticed his igate "off freqency" gating my ISS packets to IS. He emailed me asking why I had such weird packet data. What got his attention first was my forgetting to set my path to ARISS. But he then noticed the strang string. And no one today can definitively say what it is and there is NO menu setting any of us can find to change it. Not even in CMD mode in a packet Terminal.

So, who will figure it out first! Maybe it is just a Kenwood joke LOL!

NOTICE: I jut received an email from my local iGate host as I wa writing this. Here is his response.

[Re: mystery solved!]


Phillip,

Had to dig deep to figure this out but consider it solved.

Your packets are in a format called "Mic-E"

The 4RRX1S is what is called the DESTINATION field in this format where in other formats of aprs packets this would be the TO field. 

There is a table of what these packets mean and those 6 characters translate to:

42 degrees 28.13 minutes North +0 Offset in Western Hemisphere

It's your latitude. 

Find the table in this pdf:  http://www.aprs.org/doc/APRS101.PDF

On page 44 following the page numbers on the pages or page 54 of the PDF.
