I don't know if this isyour problem,but the critical frquency? (which is the easily measurable part of the ionosphere:? ?the? highest frequency a radio- ionosonde station can send upwards (vertically) and get a "ping" back) --- is dropping to really low
levels.? ?By this time in Florida, you can't communicate to nearby cities even on 80 meters.? ?
Here is a worldwide plot of the critical frequency, provided courtesy? of the Austrailian goverment, drawn from readings from ionosondes all over the world.??
--This was the impetus for my efforts to move my bitx40 to 80? meters--
?
Right at this moment, 40 meters? is ABOVE the critical frequency throughout all of the continental USA.? ?That doesn't mean that you can't reach someone thousands of miles away --- but inside your own state or several nearby it may be impossible

thanks for the research Willy. I just had 4 great QSO's with guys in PA, MD, WI and KY on 7.277. Started at 2148 Z to now at 2300 and conditions generally got worse and worse. The last QSO with PA was cut short even after moving to 7.285. Conditions just
are not cooperating on 40M lately.?
I tend to agree that we are going to have to try earlier time and/or frequency. Suggest 7.285 the old QRP freq. BTW I wasn't running QRP this afternoon - only QRP contact was VE3RDQ about 3 miles away! Will be back tonight around 0000Z (7PM LOCAL) on 277 and
285.
