Once again, the sizzling time (referring to the hot outdoor temperatures during this contest) is back! Harry WA0CNS and Herbert AF4JF attended the ARRL VHF Contest as Rovers. First day (Saturday June 12) from Winfield in EM49pa / EM49ob, second day (Sunday June 13) from Cottleville EM48qs.
We met at the Winfield dam a little ahead of time and tried to find new locations in the area. Found two promising places closer to Foley, but both were surrounded by trees which made the higher elevation useless. We have tried a RS contact with W8BYA from EM49ob, but the dish was pointing right next to group of trees. That affects Fresnel zones enough to make the contact impossible. We will keep looking in that area, EM49 is quite rare grid on microwave frequencies.
The contest itself started for us on "wrong foot". We have experienced some technical difficulties that cost us some points from higher bands. Some bands that we tested just a week ago didn't work. Since we got them working the next day, we believe that the problem might have been heat-related.

We called it a day and decided to continue on Sunday morning. However, when Herbert returned home and noticed the Rainscatter situation, he dressed again and went to the local park in EM48qs to try RS with Gedas again ... and IT WORKED!

That was a nice end of the day. However, we met in the same park next to Community College campus where this RS contact was made from in the morning of Sunday June 13 again. Probably thanks to colder temperatures, everything worked.

We were able to make contacts on 10 bands this weekend! We didn't bring our 122GHz simply because there wasn't enough space in our cars.

Everything considered, this was a nice contest. We didn't make too many QSOs, but we were active on 10 bands and we survived the heat. Even my dog was quite happy with the results:
