FD Propagation

[Edward A. Dauer]

At about 1930 Z last Sunday, during the final hours of FD, it seemed that HF propagation completely collapsed where I was. Ten went away, not ever having been open much, then 15 went completely dead, 40 at about the same time except for some locals, 80 had been useless all afternoon, and finally by about 2000Z there were only eight or ten signals left on 20.  Finis, all done, as quickly as I’ve ever seen it.  I went CL with over an hour of contest left.

Was I alone in seeing that at my Colorado mountain QTH?   Maybe I was just too tired to listen any more?

(Not entirely OT – I was using a K3 at the time.)

Ted, KN1CBR

Hi Ed 
I was up at a Red Feather Lakes, CO for FD and had strange propagation as well. Since I was the only op and there was a hot tub, I missed some prime operating hours...
Sunday morning produced an opening on 15 with skip so short I worked WY and SD. On 15m! Had to have been something other than f2.
88ft doublet up 40 feet/ends at 33-ish feet. KX3 at 15W with an AnyVolt3 set to 14.4V. No noise from this little wonder.
Not a serious effort but had tons of fun.

The majority of clubs set up before FD begins at 1800 UTC Saturday so activity falls off a cliff 24 hours later.

"3.2. Stations who begin setting up before 1800 UTC Saturday may work only 24 consecutive hours,
commencing when on-the-air operations begin."

I may be interpreting the rules incorrectly, but I think unless you started your total set-up at 1800, you could only operate 24 consecutive hours, so most everyone called it quits at 1800 on Sunday.

Propagation was still there but 95% of the stations timed out.

Only those stations that started their complete set-up, including stringing antennas etc. after 1800 could operate until 2100.

If you set-up Friday for example, then Field day was a 24 hour affair.  Of course, you COULD have started later for example, at 2100 on Saturday and quit 24 hours later, but I don't think anyone did that.

Operated at a site that used 100% K3 HF rigs (K5FD)

FD Rules allow you to setup both Thursday and Friday night!!!

No class A or B station may begin its set-up earlier than 0000 UTC on the Friday (Thursday afternoon
or evening local time) preceding the Field Day period. Cumulative set-up time shall not exceed a total of 24 hours.

A good thing for OLD timers!!
