so ive been doing contests semi-seriously for a few years now, mostly phone but been getting more into CW lately, and every time i read the writeups from the top scorers they're always talking about SO2R and how critical it is for rate. i get the concept — run on one radio while you're searching and pouncing on the second one, or use the second radio to find a mult while you're holding a frequency on the first. makes total sense in theory.

but honestly my station is nowhere near ready for that. im running an IC-7300 into a tribander at about 45 feet and i dont really have a second antenna that could work simultaneously without blowing up the front end on radio 2. i've read about band pass filters and all that but the cost adds up fast. the question is whether the rate improvement is actually noticeable for someone doing like 500-800 QSOs in a typical CQWW weekend or if SO2R only really matters when you're pushing 2000+.

also curious if there's a middle ground — like using a second radio just for monitoring without actually transmitting on it. does that even help enough to bother with the setup hassle

honest answer — for the 500-800 QSO range SO2R is probably not where your time is best spent. the big gains from SO2R come from filling dead time, and if you're not already running close to 100% efficiency on radio 1 then you're leaving more points on the table from things like not knowing when to switch from running to S&P, or not having a good feel for when a band is about to close. those are zero-cost fixes.

that said the "radio 2 just for monitoring" thing is actually underrated and I did that for a couple years before going full SO2R. just having a second receiver on 10 while you're running 15 so you notice when 10 opens — that alone has saved me mult opportunities i would have completely missed. you dont need filters or anything special for that if you're not transmitting on it, just keep the gain backed off and physically move the antenna jack if you have to. not elegant but it works.

the filter situation is real though, dont skip that when you do go SO2R for real. ran without them once during SS and my second radio was basically useless the whole time i was transmitting on radio 1.

yeah what he said about the monitoring idea is solid. i actually run my old FT-897 as a dedicated second receiver during contests, just toss a random wire out the window and let it sit on a different band. obviously it picks up a bunch of noise and the antenna is terrible but it's enough to tell you if there's activity. kind of surprised how often i catch an opening that way.

one thing nobody talks about enough with SO2R is the mental load. ive tried it a few times with borrowed gear and honestly my rate went DOWN at first because i kept making mistakes — sending the wrong callsign, logging on the wrong radio, stuff like that. you basically have to unlearn how you operate and build new reflexes. so even if you had the perfect station setup tomorrow id say budget like 3 or 4 contests just to get the workflow down before you expect any improvement in numbers
