This is normally what one would expect. However, depending on how the igate
TNC or software involved handles the packet, the unused hops may or may not
show by the time you see it on APRS.fi .
The Internet is not the be-all and end-all of APRS. APRS is first and foremost
an RF-based system. The digipeater hops path settings are exclusively an RF
AS I mentioned in my last response, you must monitor OFF-THE-AIR on RF with
another radio/TNC/display to see the true story about what is going on with
these path settings.
In fact, of the original poster's two packet samples, only one was even
digipeated at all. The first one appears to have hit the igate directly (no
asterisk after the "WIDE1-1" hop.
Or possibly some "Select", "OK" or "Enter" key wasn't pressed after selecting
the two-hop path in the Yaesu's menu, and the radio has been transmitting
WIDE1-1 only all this time. (I'm not familiar with the structure of the Yaesu
APRS menus -- I have only had Kenwood APRS radios.)
Note that an off-air monitor to look at your own transmitted packets could be
as simple as a Bearcat scanner or something similar, with it's RX audio fed
into the soundcard of a laptop running the freeware UZ7HO Soundmodem soundcard
soft TNC app.
The Soundmodem program has a built-in text display that shows the raw received
packets without needing any external APRS software. Get it here on my website:
Scroll abut 3/4 of the way down the page of downloadable stuff and look for the
"UZ7HO Soundmodem" link. Note that "out-of-the-box" the modem is defaulted
to 300 baud HF mode -- you will have to change this to 1200 baud VHF in the
pulldown menu for two-meter monitoring.
