so ive been doing contests on and off for a few years now, nothing serious, usually just hop on for SS or the CQ WW and try to crack 500 QSOs before i get bored or my wife wants the shack back. lately ive been reading more about SO2R and watching some of the top ops talk about rate and i honestly cant tell if its something worth trying to set up or if its just for the guys who are already running 200/hr and want to squeeze out more.

my current setup is a K3 and an IC-7300 sitting there doing nothing so technically i have two radios. the problem is i have no idea where to even start with the antenna switching and keeping the two from killing each other. ive seen the band pass filter setups but those arent cheap and my station isnt exactly optimized to begin with — single tower, a 3 element yagi on 20 and a dipole for 40/80. realistically is it even worth the effort at my rate or does SO2R only really shine once youre already a competent enough op that the second radio is finding mults while the first one is running a frequency

also curious if anyone has tips just for general rate improvement that dont involve SO2R. like i feel like i leave a lot of points on the table just from slow exchanges and not knowing when to switch from running to SandP and back

honest answer — SO2R at 500 QSO casual levels is probably more distraction than its worth unless you genuinely enjoy the technical challenge of setting it up. the filtering problem is real and if you have a yagi and a dipole on the same tower youre going to have coupling issues that band pass filters alone might not fully solve depending on how close they are physically. i spent a whole contest weekend chasing RF feedback issues before i got my station properly sorted and it was miserable.

where i think you'd get more actual rate improvement faster is just working on your CQing discipline. a lot of casual ops dont hold a frequency aggressively enough — you give up too fast when its slow and then youre back to SandP which is always slower for rate. the rule i use is if im above maybe 80-90 an hour running ill stay on freq and if i drop below that for more than a few minutes ill go hunting for a bit. also just getting your exchange down cold so theres no hesitation — that alone probably saves 3-4 seconds per QSO which adds up badly over a full contest period.

the second radio thing does pay off but really its most valuable for finding mults while youre running. if youre not running a freq consistently the second radio doesnt help as much as people think

yeah the bandpass filter cost is the thing that stopped me too for a while. i ended up going with the 4O3A filters eventually and they work well but it was a commitment. one thing i'll say though is even a crude SO2R setup where you're just using the second radio to listen on another band while you transmit on the first can teach you a lot about the workflow before you invest in the full filtering setup. you obviously cant transmit on both at the same time without the filters but just having it there to spot mults passively is something.

for the running vs SandP question i think the band conditions matter more than people give credit for. early in the contest when rates are high almost everyone should be running if they can hold a freq. later when the pileups thin out sometimes aggressive SandP on the second day is actually better for your score depending on the contest. SS is a bit different since its all domestic but in WW knowing when to go hunt europe vs stay on a freq is kind of an art honestly
