Decided to check out 3250 based on this report, as it's a WBCQ frequency I have never copied. There's a very rough signal there on my PL-600 with its whip antenna. (My bigger loop, which can tune almost that low, is in the shop so 90m listening is restricted to built in antennas for me.) Not bad given that it's still not dusk yet. Will check again in 1/2 an hour.
