The topic of propagation conditions was probably the most discussed during the May round of the OM Activity Contest. Several stations mentioned it directly on the band. Paradoxically, this may even be an advantage, as it reduces the effect of mutual interference.

Compare the signal from OM0AD
Ivan is a regular participant in 80-meter contests. Here’s how his signal sounded in the SSB League:
A week later, OM0AD in the OM Activity Contest:
On my end, the only change was in power: FT-1000MP 100W into an inverted Vee antenna on an RDM-12 mast. Logging contacts with N1MM+.
OM Activity Contest May 2023
In the first few minutes of the OM Activity Contest, only a handful of stations are calling, but interference from nearby stations isn’t significant. So I keep calling the call sign. Things gradually pick up from there. OM3KEG puts a stop to it by launching a call on exactly this frequency. Experience tells me there’s no point in trying to resolve it.
I had already “collected” a few callsigns using my second FT-1000MP receiver. The idea is that I log the stations responding to the call in the second N1MM+ window. Once tuned in, their times are displayed in the bandmap, and retuning to them is just a matter of a click. Spotting stations provided additional call signs like these on the bandmap. This way, calling stations is very fast and more efficient than issuing a call.

However, I return to calling out multiple times in various sections of the 80-meter band for the OM Activity Contest. It’s easy to see which stations have a good grasp of the band. With the advent of SDR equipment, it’s clear who knows how to use it. The last contact, number 74, belongs to Tibor OM7CF. In the last fifteen minutes, I’ve logged seven contacts.
