Jeff
Thank you.
Europe in general uses 3580 to 3620 for RTTY but it will spread higher and
lower during peak occupancy.
I would expect EU to move below 3570 at peak times. Asians often go below 3580
and lower to avoid the EU QRM so EU will work them below 3580. I have worked
them below 3570 but unusual.
I expect 7045 will be very heavily used in EU as it is in the middle of the
data segment. No chance that will be avoided. I also expect EU will go above
7060 as 40m will be a prime DX band. See

hi David - This is just my observation, but since the 3600 KHz upper band limit
went into effect, we seem to crowd between 3580 and 3600. Overflow as needed
will start at 3570 and head down - we'll also be looking for JAs there.
Please don't spend all your time above 3600. ;)
Where does the UK normally operate in this contest? 73 jeff wk6i

What is the likely USA 80m frequency segment that will be used? Any hints on
how UK might avoid very congested segments would be helpful.

I was asked to provide this - like I'm an expert ;) - but I did some digging
and this seems to be a good start. If anyone else has further info please do
chime in.
First, the information I have received is that the following frequencies
within the RTTY segments may contain emergency traffic. Please take steps to
avoid them:
7045, 7060, 7075, 7090
14120
These are all phone nets and we are asked to give them wide berth (phone
bandwidth). For obvious reasons there may be weak stations you can't hear
but others are trying to hear them. (Source: ARRL and others)
Also don't forget about the beacons at 14100 and 21150 - NCDXF recommends
giving them 500Hz on either side, at least. (Be nice if 21150 was actually
an issue!)
And of course, there are our friends using various other digital modes in
the 70-80Khz segments on each band.
And remember that the US 80m RTTY band is limited to 3500-3600. Non-US
stations CQ-ing above 3600 please consider listening below as well.
Have fun! 73 jeff wk6i
ps: Please do not avoid 10m. Take a listen and throw out a couple CQs. You
never know.
