I have been using the address ‘www(dot)sota(dot)org(dot)uk(slash)Spotlite(slash)displaySpot’ on both my payg mobiles for some time. One, on Vodafone, with keys, works OK still (except that on GW/NW-044 this afternoon I was on the wrong side of the summit for signals and the battery was low). The other, a touchscreen mobile on T-mobile, keeps reverting to old spots when I change the contents of other boxes. In some desperation today I spotted with what IT wanted to spot (albeit with the correct frequency) and, very kindly, a chaser corrected the spot for me.
Is there a more modern address to use for self-spotting, please?
SMSbot(SMSbotNA) (I wrote them). You send an SMS to a UK(USA) number and the spot appears on SOTAWATCH. Access control is by pre-registration. Mail me (mm0fmf_sota AT intermoose.com) if you want access.
APRS. If you have APRS capabilities you can send spots and alerts over APRS. Stewart G0LGS runs a server, I’m sure there are others. Mail Stewart for the details.
The advantages of using SMS over mobile internet are based on observations made by many people. There are many summits where you can get a mobile signal but not be able to get a mobile internet connection to work. However, sending and receiving an SMS tends to nearly always work if you can get a signal.
Pick whichever takes your fancy. They all do exactly the same thing.
