I'm surprised I haven't seen any post about this past weekend's activity. A bit of hit and miss Es made 6 meters interesting here in EM95 on Saturday. But the highlight of the contest was the tropo o
The East Coast 70 CM net will operate as usual tonight during the sprint. I don't believe this has caused a problem in the past and I know it has helped many stations make contacts they otherwise wou

These newbies are what I believe is our most valuable operators and are often overlooked. I think some consideration should be given to recognize them. Perhaps a category in which the score is based
Zack, I bought a LO crystal to make the change to 902 several years ago but haven't done so yet. I use a DEMI xverter with a FT-221 IF and the IF radio will not tune down to 143.100 MHz. However I ha
Got home to late to get on also Dave. Seems like the same happen last year. Maybe there would be less of a schedule conflict if the 6 meter sprint was on Thursday night instead of a Saturday? And whi
