Hello Chris and Co
I would say that the QRS mode is useful under
certain adverse conditions but even that is debateable because of the very
slow speed of data transfer which leaves it vunerable to garble caused
by bursts of noise, static and the proverbial QSB which seems to
be more prone on 500 khz probably because of the permitted
max power being so low. This observation has been made by others on the
band besides myself.
On normal CW working which allows a quick exchange
of information this is not a problem also one can use QSK to advantage which is
not an option on QRS mode.
All the current stations active on 500 both in the
UK and EU are audible with me so why would I want to work them on QRS when I
could exchange the relevant information in a few secs/mins and even have a
discussion when this would take an hour plus on qrs plus the disadvantages as
discussed above.
Why would anyone crawl when they can WALK.
From info published from the USA, those using the
500 khz band prefer normal CW. This LMCW mode is not used on any other amateur
band, so why 500.
Beacon use also needs a mention. A more
useful and considerate approach would be to beacon at around 6 wpm
with call and say locator any other info is not normally necessary,
again the slow qrs mode is not appropriate and sometimes in the evening
there is more of this activity than QSO'S taking place, so what is the
point of these endless transmissions. I do not see this
reflector swamped with reports and the odd one just confirms what
happened the day before from the same source.
My suggestion, if one is compelled to beacon, use
normal 6 wpm cw and listen at a specified time for a possible QSO ie on the
half hour or hour, or any other suitable time
The 500 khz band has always
been designated primarily for Telegraphy.
To date as far as I know all QSO'S that have taken
place have been on normal CW and you have a good strong signal always
589 with me and I am sure you are equally strong with all the others on the
band. I do not suppose with your signal and your ability to send
good CW you would acticipate using LMCW.

Subject: LF: QRSS on 500 kHz
It appears that the use of QRSS modes on 500 kHz is
unfortunately somewhat contraversial.
Admittedly this band has a
particular historical heritage and it would be a shame were traditional CW to
become a minority mode.
I prefer manual CW to any other mode but QRSS
has its place too.
My N.O.V. entitles me to use CW, QRSS and DFCW on 500
kHz.
As far as I am aware there is at present no 'gentleman's agreement'
for band segmentation regarding the various modes.
Maybe after nearly 3
months into the year's trial it might be opportune to consider one.
The
usefulness of QRSS is obvious but appears to need restating:
a) Those
amateurs who are not fortunate enough to generate a strong (or even decent)
signal may still work other, even DX stations.
b) QRSS QSO's may be
time-shared with other activities e.g. construction or metal work.
c) It
generates a bigger 'presence' on the band - useful for any interested parties
who may be testing an RX, aerial system or investigating propagation.
d) It
allows the involvement of some of our more distant non-G friends who may be
interested in the band yet have no transmit entitlement.
e) The bandwidth
of QRSS is very narrow and hence spectrum efficient.
Have there been
any UK 2-way QRSS QSO's on 500 kHz ?
Is there any interest in having QSO's
in this mode?
I anticipate reducing my transmit power by say 40 dB and
calling CQ late at night in QRSS. At this low level it should cause no
interference to any CW activity.
If there are no serious objections then I
shall suggest a frequency and time at a later date.
