APRS equipment for APRS2SOTA


#1

Hi all,

I use APRS2SOTA because I like packet-radio and it is easy to use. However, lately I have had problems with it and in my last Sota activation, on CT/ES-003, I was not able to self-spotting me (tks HB9BCB/P for spotting me). I have a Tinytrak4, a dynascan db-48 vhf/uhf ht, a GPS antenna (connected to the TT4) and to send Aprs msgs I use APRSDROID software.

At home this setup works quite fine and I do not have big problems with it.
Problems appear when I am in SOTA operation, there is always a small problem:
sometimes I do not have TX, other times I do not have RX, etc etc etc.

So, I wonder to know what you use for APRS2SOTA ?

Do you have a setup like mine or other kind of setup ?

I want to know to improve my setup.

Best 73.

APRS for SOTA (up to date suggestions?)
Self-Spotting from a Smartphone a Fair Means?

Hello David,

seems not too many activators have suggestions for your problem. I wanted to avoid the hassle with all the cables and devices and purchased a Kenwood TH-D72 all in one APRS-HT recently. Did not try out APRS2SOTA up to now but transmitting the position and receiving all sort of packets is fine. Have to play around with messaging in the future.

In reply to DB7MM:
The best is a THD72 because the Yeasu line of GPS handheld cannot send messages to APRS2SOTA because you can’t enter APRS2SOTA in the message screen.

My Yaesu VX-8GE does the job right and Stewarts APRS2SOTA server works very reliable. A few moments after sending your message you receive a “QSL, spotted!”. The following message transmissions are answered with “dupe” because Stewarts server already posted the spot. You just need to send your message to “SOTA”, e.g.

to callsign: SOTA
aprs message: OE/SB-225 14.285 SSB OE2ATN/P comments

It even works if you send the message without your callsign in the message text. So you can also spot a second operator via your HT! I`ve done this sometimes when we were 2 operators with one APRS-HT.
1st message: OE/SB-225 14.285 SSB CQ! >>> spotted as OE2ATN/P
2nd message: OE/SB-225 7.032 CW OE2SNL/P CQ! >>> spotted as OE2SNL/P
…both from my OE2ATN-7 VX-8GE.

Of course your callsign should be on the “whitelist” at Stewarts server.

Hello David, I also have the Kenwood D72E h/h - it works very well. I did replace the supplied antenna with a whip antenna. Full spec’ on link.

I did not know about that. I will try it with my VX8G for sure. Thanks.

Hi all,

tks for all your answers.

Well, I know about the Kenwood th-d72e and the Yaesu vx-8ge, they work very well for what I want. However, they are both a bit expensive. Next Monday I will phone to Kenwood Portuguese seller to know price.

Anyone using a tinytrak4 ?

Best 73 and till next email.

I’ve also used a Kenwood TM-D700 running UI-View from
the mobile and have spotted prior to leaving for the
summit. UI-View has a slick way of sending/RX msgs.

Later,

Hi all,

just to inform all that I have bought a Kenwood TH-D72E. It was a bit expensive but works very well and will perform well for sure.

Best 73 and good SOTA activations.

Hello David,

“just to inform all that I have bought a Kenwood TH-D72E”

Yes it is a bit expensive but you get a very good radio. The MCP-4A software works well especially the APRS beacon options - have fun! Hope to track you in the future!
Goodnight.
