Many thanks for providing such a reliable service. My SOTA adventures wouldn’t have been nearly as successful without them.

hi stewart,

thanks for running your gateway and for the stats! your APRS2SOTA service has become my favourite way of spotting myself on a summit.

Hi Stewart,

Thanks for adding me to the whitelist!
I just managed to send a Test Spot via APRS2SOTA, after failing for several times.

It seems i’m in APRS2SOTA business now :slight_smile:

Many Thanks fpr providing this excellent service!

Dear all

APRS2SOTA is a good thing for me since starting SOTA when out of mobile coverage and for me as an SSB guy (the CW operators have RBN at least, as long as it is alerted, or their standard frequencies, thus better than nothing).

You simply have to cope with the old-style SMS-like handling and let a sent APRS2SOTA spot count down to avoid rebroadcasting the old spot from your next summit if you turn off the spotting device too early.

Was happy to have it once this May at the DL/OK border with neither mobile data nor cellular phone/SMS coverage.

Thank you for APRS2SOTA! It is my primary spotting tool. I have used it successfully from many remote summits in the Montana and Idaho backcountry.

I have to chime in and add my thanks for this extremely useful resource. I’ve used APRS2SOTA on many remote summits here in the PNW. Many of those activations would have been failures (or taken way too long!) without APRS2SOTA.

Thank you sir!!

How do you know when that is complete Markus? (I’ve never tried APRS)

When you send a message to “SOTA” it is heard by a local I-Gate and gets forwarded to the APRS2SOTA gateway:

You receive two messages, an “ACK” and the second one lets you know that you were successfully spotted on SOTAwatch:

When there are only RX I-Gates (without TX possibilities) in reach of your SOTA summit it can happen that your device is not receiving the answer messages. Then your spotting message is repeated up to 5 times by your TRX. If you turn off your handheld after the first sent out message and power it again on the next summit it can happen that the old message is sent out again by your device … and a wrong spot appears on SOTAwatch!

After I spot myself via APRS2SOTA I keep the TRX on the APRS QRG for at least five minutes, then I can be sure that the message will not be repeated again.

Great to see it growing in popularity. I’ve found it really useful.

I use a Yaesu FT-1D for APRS spotting. In the message list it shows you how many retries are left, and you can also delete messages. I usually check the message list and delete any messages with remaining retries before I shut the radio down.

I had exactly this situation on a summit last week - I wasn’t getting any ACKs so I had no way of knowing if I was getting spotted until the pileup arrived =)

Hi Andy

Martin, OE5REO, puts it in a nutshell – simply wait these 5 minutes (5 retries, about 1 retry per minute) before turning your device off. The number of retries and how to check this out is described in the manuals of the handhelds. Mine is an FT2DE and offers exactly these possibilities.

Wait the 5 minutes or delete the specific APRS message if you want to submit a new/different SOTA spot.

An APRS coverage can in general be expected in my area.

I have created a page on my web site with the updated versions of the above Stats and a few more:

It will generally be updated once a day.
