Well, 4XTECH showed up on the display of my mobile D710 a couple of times, but I didn't get a MY POSITION. I wasn't able to find anyone local to listen out for me.
The good news is that it is easier to see one's self via GO32 than via the ECHO satellite, because GO32 has a PTT delay some of the time. So your radio will have turned around in time to hear your packet come back... But being in the mobile, you probably only get a good -downlink- for the center 3 minutes of a good high pass.
But you can get in on the uplink from horizon to horizon if you are running your typical 50 watts mobile. That is why we need LOTS more people Igating the downlink.
The best way to do this is to encourage all D7 owners that do not use their D7 routinely, to not just set it in the closet, but leave it hooked to an Igate all the time they are not using it. Connect this through a SHORT coax to a 19" vertical whip.
This station will receive GO-32 downlink packets for the center 3 to 5 minutes of the best two passess per day... And if we have enough people doing this (say a dozen over the USA), then at least one of them will always have a good chance of hearing each packet and feeding the APRS-IS... Thus giving mobiles all over the continant the ability to get out a positon, messsage, or email from anywhere.
And since coax loss is the big bugga... The better way is to put the D7 up near the antenna and run only the 3 wire RS-232 down to the shack... Then you don't need a pre-amp... Shucks, you can even use the same RS-232 to remotely control the radio, and use it for other weak-signal reception work as needed too...
