so ive been running SO2R for a couple years now but sweepstakes always humbles me. i feel like my rate just falls apart compared to guys running single radio. maybe im overthinking the second radio or something. my setup is a K3 and a K3S, both into a 2x2 matrix switch, antennas are a tribander at 50ft and a 40m wire yagi — nothing fancy but it works most of the time.

the problem is i feel like i spend so much mental energy babysitting radio 2 that i lose my rhythm on radio 1. like i'll have a good run going on 20 and then i chase some multiplier on 40 and suddenly my CQ cadence falls apart and callers give up. is this just a skill issue that goes away with reps or is there some strategy adjustment that actually helps

also curious if anyone has strong opinions on when to break a run for a mult. ive been using a rough rule of anything over 5 kHz away and i wont chase it mid-run, but that feels like it might be too conservative. sweepstakes specific answers appreciated but general SO2R tips welcome too

yeah SO2R is genuinely just hard and it takes way longer than people admit to get comfortable with it. i think i ran it for 3 contest seasons before it stopped actively hurting my score. the mental load thing you're describing is real — you're basically training yourself to do two things at once that both require full attention, so early on one of them always suffers.

the rhythm thing on the run frequency is the key issue imo. what helped me was basically treating radio 2 as completely passive for the first hour or two until i was in a groove. like yes you're leaving mults on the table but your rate on R1 will be higher and you'll end up ahead. once the run frequency starts slowing down naturally, that's when R2 becomes more valuable because you're not sacrificing as much by glancing away.

on the mult chase threshold — 5 kHz is probably fine for sweepstakes since it's not a crazy multiplier contest, there arent that many mults to chase. i'd tighten it to maybe 3 kHz and only break if it's a section you genuinely need. if you can hear the guy on R2 while you're calling CQ and he's still there after your next CQ, then chase him. if you lose him, move on.

honestly the 50ft tribander might be part of the problem too, not blaming the antenna but on 20m that's not a lot of height and you might be losing runs because your signal isnt as strong as you think it is on the east or west coast. i noticed a huge difference in my run rate when i got my beam up higher, fewer people had to ask for repeats which kept the rhythm intact.

not really an SO2R answer i know but if the fundamentals are working against you the second radio stuff gets harder to diagnose. also what keyer are you using for the SO2R switching, i'm trying to figure out if the microHAM stuff is worth the price for a first SO2R setup
