Inspired by this thread, did a brief test transmission with the Sternradio equipment and managed to get a reasonable signal out on 25.820MHz.  A bit different of a coverage area than the usual range from East Antarctica.

Here's one of the issues you've got with 11m transmissions, not as many people tend to be SWLing during the daylight hours.

Another is not many listeners will be actively checking the 11m band for pirates. Although that can be remedied to some extent by letting a few listeners know in advance. Once a broadcast gets logged by a listener, others will follow.  ;D

 Hey All,

I am not even sure of the "risk factor" when using shortwave (compared to AM, especially below the X band  and DEFINITELY  on FM  ) . And again if there IS one, would posting in advance increase it ? Can't say .

I am COMPLETELY off the air  ( ham , CB and "other" transmissions ). Had my fun , but  now keeping a LOW profile on receive only.

About the only transmitter I am interested in now is  an ultra super low flea AM'er (range in inches or a few feet at BEST ) to play around with (ie  as a  beat "tuning aid"/signal gen  for crystal sets, etc) .Even that hasn't been a high priority on the bench .But I'll get 'roundtoit "eventually".
