At 9:15pm my time (EST) I was on both 175 and 178. I can hear the NET moderators 5-9 and very clear. some stations were clear, some not. I got a strong station from Utah. I did hear a station from Denver, but they were talking weak with the strong moderator.
I called CQ CQ CQ Denver Colorado on 177. But the moderator from 178 got back to me politely and firmly "the frequency is occupied!"
The 175 and 178 were doing endless rounds of signal reports and I did not stick around for long.
Bruce, I can go out lunch time 12PM EST (your 10am) to do CQ Denver on 40M.
Let me know a start frequency. I can try 177 again.
