At times one has heard two Sotas on one freq but feel there not in each others catch zones and no doubt can't hear each other it happens and tops of mountains can be the deadest of places for cell reception. But chaser being from many parts of world can give game away if the regulars are calling in and using far more bigger power. But have been chasing one Sota at times and then as it finished off another pops up.
But after two years of chasing Sotas has a strange one couple weeks ago, heard one Sota calling worked few chasers, called in a S2S and worked each other. Then caught the first one did the usual things and next thing I know that Sota is calling back and twigged was different voice. Then thought perhaps multi op on same summit, turns out not so but the 2nd Sota that just worked the first was now working me. double whammy. two sotas on one freq with in seconds of each other. Then the 2nd Sota vacated the freq and the first carried on. rather chuffed with that.
But being a low powered station myself nigh on QRP with the limited 10w I have at hand often get jumped on by a more powerful station but it happens they prob can't hear me due to way conditions running , two got more power than efficient antenna or just bully there way in.
But does pay to key up and ask IS THIS FREQ IN USE, if reply comes back you move on or even join in.
But my biggest grid is when stations accuses you not running the power other than what you are licensed too like myself at 10w limit and not even ID them selves as they should do. Why do i do so well, its my location on top of big hill in area i live in back end of m small town, not to built up and making antennas to take my little old 10w and make it earn its keep by running more better antennas. May b there are those that run more than they should but have heard some that even exceed the power limits of there full licences. And lastly Technics gain with with experience of known when to call in or not times i have beaten the big boys toys with my simple old set up make me grin
Right sorry for that little bit of slight change to current subject
