[K3PZN-List] RI1ANF at Bellinghausen Base

[Curt Milton]

Jim

thanks for sharing!  my experience on top band is that usually there are only a few DX signals - so even when it is F* or G* or DL*, that everyone has to pounce in and try to work them - often with their kW and full sized verticals!  (somehow still, I am up to 71 entities on 160m).  


so working RI1ANF is very cool (err cold!) indeed.  they were the only DX I heard last nite when I had the rig briefly on 160m CW -- they seemed workable, but I sensed every 160m DX'er was after them!  I presume you were on a digital mode, in a bit less traffic?  


those who don't do much on top band haven't heard that it often has a 'ducting effect' - not as pronounced as 6m but very real, where a particular path is favored at a given time.  also, that QRN is also skywave ... but I wonder if perhaps that they may be as distant from the topical storms as you are (meaning low QRN there).  


a year or two back I worked an Antarctic station not at a base, but in a tent!  


BTW, my little ~260 foot Beverage indeed is very useful - thanks for the encouragement.  


with sunspots being a bit scarce this cycle, anyone interested in DX should be equipping their station for low band operation.  in my case all I use are short verticals (which are much more effective than long dipoles) and 100w (ok I am wishing for a 0.5 kW amplifier some day).  


CUL Curt

Hey just worked RI1ANF at Bellinghausen Base, King George Island in the South Shetland Islands this is the little appendage that comes out of Antartica and heads toward South America.. I have been trying to work him since september but this is the first time he has been of such quality he could be reliably copied. This is no trivial task on TB .. remember it is summer down there and mostly light all the time so he should not be able to hear me .. theoretically

Thanks Jim,
Friday, I will be at the Fisher Building at noon with my mother.  She is in physical rehab there Central MD Rehabilitation Services.  They are on the ground floor,
around back.  This is the 5th session and she walked with no walker today, used a cane for first part then up and down the hall with the therapist but no cane.
She has a few dozen or so more sessions, but for 90 years old they are really amazed at her progress.  Most sessions are at 12:30 M W F, except Feb where she
has some medical appointments.  Would really like to join you, but just cannot at this time.  Just checked the sked, won't have an open Fri until 2nd Fri in MAR!
Most anytime after 2:30 or so OK, usually have her home by then.  So, I could stop by this Friday, but probably be around 2 PM?
