Hi Uwe
thats the sence of the castle mode, Eddie.
Yes that's fine for an 'E' or a 'T' but a figure is five different
rising / falling frequencies which take five times longer.
Can you transmit 5 different frequencies? How about making your own
code Freq.1 = D, Freq.2 = J, Freq.3 = 8, Freq.4 = W, Freq.5 = X , 2
hours per symbol, gives your full call in 10 hours, just twice the
time taken for Castle to send one figure at your 1Hour symbol time.
It needs to be a locked frequency, a divider step, of course, this
could be controlled by a PIC to release the computer.
OK there has to be something wrong with this idea, someone blow it
out of the water.

thats the sence of the castle mode, Eddie.
the only handicap here is the stnd alone generator because
the shift is too wide for VLF.
but I dont like to use a PC as beacon generator.
seems I should tx in carrier mode agn (8970.022Hz).

Hi Uwe
I have seen some clusters of dots here but your symbol time is
not
long enough to be sure. Castle is pretty difficult to follow on
an
R5 signal at QRS3, Step is better, but I would say that, I
developed
it.
If you are using multiple frequencies then surely the absolute
coding system used by Marcus is far superior and would cut the
time
to send a letter or figure and allow longer symbol time giving a
chance of decoding here as opposed to zero.

Hi all,
an hour or
so
ago the DJ8WX TX has been switched on.
QRG:
8970.022Hz
Mode: CASTLE
Speed: 3600
(means one sign = one hour)
Shift:
119mHz
(sri, but I cant get it narrower programming an
EEPROM
AT90S2313-10PC)
QRGs
occupied:
8970.082Hz and 8969.963Hz.
So it shows
the
letter:
The TX will
be
on the air at least until tomorrow late afternoon
when my XYL
begins her garden work.
Meanwhile
she
knows the PAs off-switch
and she
doesn’t
hesitate using it disrespectful (when getting an
electric shock).
but today
she is
on shopping tour.
