I received a note from one of the directors at Radiostation Grimeton in 
Sweden that they are considering a wintertime cw transmission of SAQ 17.2KHz when 
conditions are optimum for worldwide reception on VLF. He asked if there was 
any particular day, time of day and month of year that would be best for radio 
amateurs and radio hobbyists to listen for their signal. I told him I thought a 
Sunday morning transmission would be optimum when most radio amateurs are 
home from work and radio noise is usually quietest on a Sunday and that January 
and February are the best months of the year for low static on VLF. Does this 
sound good to most everyone here? He said they have run into problems in the 
past with cooling water for the Alexanderson Alternator bearings being too 
chilly in the winter months but they are working to fix that problem. This would be 
a great opportunity for more hams worldwide to listen to their VLF 
transmission under optimum conditions. Now would be a good time of year to pull out your 
R-389s, SRR-11's, RAKs, RBAs and other cool tube and solid state VLF boat 
anchor receivers from storage to make sure they are still working properly!  
Conditions are great on LF/VLF right now! I will pass along any news if they 
decide to go ahead with a wintertime transmission!   73 Todd WD4NGG.
