Multipliers are key in the RTTY Roundup to make the highest score. You also of course need and should maximize rate to get the Qs, but a little looking around can pay off.
1. In last year's Roundup, there were 90 DXCC entities available, excluding mainland W and VE: 4 Africa, 15 Asia, 44 EU, 10 NA, 9 Oceania, and 8 SA. And all 48 states, DC, and 9 provinces were represented last year (VE4 notably missing). That makes 148 total available multipliers. The top stations last year had over 130 of those.
2. If you are comfortable with packet, enter as Unlimited. Last year Unlimited entries typically had 10-20 more mults than the corresponding unassisted categories.
3. The good news is that multipliers count only once, so take advantage of - and anticipate - band openings to different parts of the country and world to fill up your mult list.
4. Be aware of band plans in other parts of the world, especially on 40 and 80. You'll find plenty of domestic stations above 3580 and 7080 and some DX, but a lot of DX will be lower in the band on 40 - around 7035 to 7055. On 80 Asian and Oceania will be below 3575, down as low as 3525.
5. A third of those DXCC were represented by one callsign. Work them when you got them! It can be worth it to spend a few tries to beat the pileup. This also applies to VE4. ;)
6. When you are running be aware of the power of the Skimmers. Throw out some contest CQs and search the RBN for your call before the contest to make sure they are decoding your CQ. And move once in a while to make sure you get re-spotted. Here -

I've copied last year's DXCC entity list below for reference, but hopefully more than this will be available!
And if you have anything to add please chime in.
Have fun! - jeff wk6i
