If you can configure the KAM to be always in KISS mode, configure the port type in APRSISCE/32 to be Simply(KISS) to avoid having it taken out of KISS by accident.  The KISS (not simply) is for Kenwood APRS radio TNCs (except for the D74).

From your post, I would recommend:
   Port(APRSIS) -> indicates what is received and sent to the internet
   Port({KAM}) -> indicates what is received and sent on RF
These open additional windows to view activity.

If you want your station to work properly with APRSISce/32 and the KAM, you really need to place the TNC in KISS mode.

As I recall, the KAM XL require a power cycle after sending the INTERFACE KISS command.  Placing the TNC in KISS mode through another application may be the best method.  Other KAM (like the KAM Plus) only require the INTERFACE KISS command.  Check the WIKI for information on editing the XML for OPEN and CLOSE commands:

how can i tell if my home station if spotting received aprs RF to the internet?

is there a easy way to fake a gps and send location packets from the home station
using a old kam typically not in kiss mode?

I would think someone would have made a online calculator on a web page that you input

The Google Maps API is a totally separate issue. Not related to
Bryan's issues, but as always the APRS-IS stream is a source of bad
data to use for evaluating the performance of your APRS RF system.

The best source as always is to put a radio based system on the local
RF channel and evaluate your station performance using information
seen by the station.

I think Bryan has more underlying fundamental issues with his station
that need to be corrected before we go down the road suggested.

I replied to Bryan off-list in an attempt to work towards getting
those fundamentals looked after.

It doesn't look like his station is hearing APRS network traffic
properly, so it's tough to digipeat something you can't hear. There's
also the challenge of knowing how to determine if your station is
doing what you think it should by looking for evidence at places like
aprs.fi or other APRS-IS filtered sources.

I'm hoping to be able to get him sorted on the basics, but it's not
something pertinent to this forum.

The following <Open/CloseCmd>s are the result of selecting KISS as the port type in APRSIS32.  This selection (which needs to be renamed) is actually designed for the Kenwood APRS radios (but not the D74) to put them into KISS mode when they are initially in Packet12 mode.

You need to disable this port and create a new port selecting Simply(KISS) as the type.  Then make sure that you have externally configured your OT3m to be in KISS mode when it powers up.  With that configuration, please ensure that you are actually receiving packets from the TNC which is indicated by an asterisk (*) next to an entry in the packet scroller to the right of the display.  You might want to check Configure / Scroller / RF Only so that only RF-received packets even show up.  I also find that Configure / Scroller / Show Igate/Digi is very informative on instances with active RF ports.

You may also want to open and enable the Enables / View Logs / Port(<YourPortName>) trace log to monitor some communications with the TNC via the port.

Once you have confirmed that packets are coming in to APRSIS32 from the TNC, you can poke Transmit on the menu and make sure that your radio keys up.  If not, there's a Wiki page that has a list of things to check.  The Port(<YourPortName>) and Transmit trace logs can also help diagnose failure to transmit.  But don't expect transmit to work until you've confirmed that receiving works!

http://aprsisce.wikidot.com/doc:transmitting

<!--DigiXform-->
</RFPort>
<!--RFPort[0]-->

<DigiXform>WIDE1-1=WIDE*</DigiXform>
This is the correct <DigiXform to modify, but as was pointed out, the WIDE* should actually be WIDE1* since that is the original path component that is being "used up".

Once you have receiving and transmitted working as described above, this digipeater configuration should "just work", provided that packets are being received whose first unused path component is WIDE1-1.  You should have some Digi(*) trace logs showing up that will help you debug digipeating once everything else on the port is working.  Note that you'll have to make sure these trace logs are enabled or there'll likely be nothing in them.

This link which James provide is actually a good one to show who your IGate is copying packets from over time.

http://ldeffenb.dnsalias.net:3000/catchall?FormName=RFTRAFFIC&Action=Display&IGates=kb9uzo-1

I also checked the raw RF reception logs for KB9UZO-1 and it appears that you are receiving packets that would digipeat with a WIDE1-1.  So, once you get the port type straightened out and ensure reception and transmission, you should be up and running. Remember, the Digi(NOT) trace log is probably your best friend.

BTW, do you know if the FTM-400 supports digipeating internally?

The FTM-400 is a great stand-alone APRS radio, but it doesn’t do digipeating.

Of course, it’s also a great FM and digital C4FM voice radio. With a super-deluxe colour touch screen, it’s probably the best one for sending/receiving APRS messages and it can do the same for digital text messages. It can also send/receive colour pictures.

Did I say it was a great APRS Radio? Just no digipeating and RX only output from the TNC.

As with just about anything else in life, it is always best to learn
and understand any project that you are going to start before you
decide to get after it. Take some time and read up on what APRS is,
what roles digipeaters play, what roles i-gates play, and how the APRS
system as a whole works. Read up on the products that you have, such
as the OT3m, and also the software you are running. Once you gain a
basic understanding of all that you are working with, it makes it
easier for others to help you out. You will be able to converse about
the basic functionality, using common terms used by those who are
familiar with the products and systems.

You'll probably also learn the answers to many of your questions along
the way by reading the documentation for the products and software.

Right now, it looks like you may not have the basic functionality set
up, let alone working at getting a digipeater functioning. Either
that, or the APRS frequency is very dead in your area.

I'm not using an FTM-400 (I don't have one), but I believe the instructions for the FTM-350 and APRSISCE/32's support for the same should work.   You might want to read the following page of the Wiki:

http://aprsisce.wikidot.com/ftm350

If you work out any difference from this information, post it here and we can see about getting that page updated, or a dedicated page created for the FTM-400 if the changes are substantial.

BTW, do you know if the FTM-400 supports digipeating internally?
