First North America-To-South America Contact On 902 MHz Moonbounce Reported:

Some hams may not even realize that there is a ham band at 902 MHz, but Bruce Halasz, PY2BS, in Embu, Brazil, reported on the Moon-Net reflector that after months of preparation and testing, he and Al Ward, W5LUA, in Allen, Texas, completed a two-way EME (Earth-Moon-Earth) -- or moonbounce -- contact on the band on June 8.

PY2BS said the main issues he had on his end involved reception, including "an in-band noise from another service" that he could not eliminate by filtering. "Fortunately," he said, "its bursts are spaced enough apart to allow [reception] from the moon-coming signals in between them."

W5LUA has a 5 meter solid dish and was running about 400 W at the feed point. PY2BS used a 5.1 meter mesh dish with 180 W at the feed point. Both used very low noise FET preamplifiers. W5LUA and PY2BS exchanged reports on CW (549/559) and JT65C (-17dB/-18 dB).

"We've found out that [the] Faraday [effect] does exist at 902; [it] just rolls kinda slow," Halasz added. He said his 902 MHz setup is temporary, but he is interested in contacting other stations. -- Thanks to Bart Jahnke, W9JJ
