Ham Member Lookups: 11299

 

Awards: WAS, WAC, DXCC

I'm an RF electrical enginner and I work at Motorola HQ in Schaumburg, IL designing 2-way MOTOTRBO mobile radios and repeaters. I earned my BSEE from Michigan Tech and my MSEE from the University of Tennessee. I was a past officer and president of both college amateur radio clubs W8YY and AA4UT. I've been licensed as a ham since 1996. I sit on the tech board the North Shore RC (NS9RC) and the Motorola ARC (K9MOT). I am also a member of the ARRL, Keweenaw County RA (K8MDH), and OMISS. OMISS is a worked all states net and my member # is 4948. I am a former webpage editor for the Copper Country RAA and KCRA.

PACKET: I operate an Xastir APRS 2m i-Gate and weather station on 144.39 MHz at home (AA9VI-10) and you can also contact me via a brief text message to my vehicle (AA9VI).

ANALOG REPEATERS: I am also sysop for IRLP node # 8721/Echolink Node #7641 on the 443.575+ TPL 114.8 repeater in Schaumburg. I also operate Allstar node #42060 / Echolink Node #7694 locally on simplex 445.55 MHz TPL 114.8 that serves the Palatine/Hoffman Estates/Schaumburg areas.

DMR: I enjoy working with MOTOTRBO DMR radios on the ham bands. We currently have a half dozen local DMR repeaters that use the 2 slot (channel) digital protocol. Both networks are fun. I am sysop for both the K9MOT repeater (444.79375+ CC1) and my AA9VI repeater (441.21875+ CC1) that are on the DMR-MARC network (800 worldwide repeaters in 18 countries). I also sometimes have a DMRPlus repeater with time slot 2 on 444.8375+.  DMR is rather new to ham radio but it's really neat (think awesome voice quality, great RF range, extended battery life, and 2 voice channels from one repeater). The repeaters and radios are really well priced, and have multiple manufacturers to choose from. Obviously, my preference is Motorola MOTOTRBO.

D-STAR: I recently purchased a couple D-Star radios. The D-Star networking is supurb but the Icom RF design, especially the RX side needs some serious work. The RF range is limited due to the Icom repeater 25W TX output, the poor RX selectivity and poor intermod rejection. So, that's what prompted me to begin my latest project: A Robust non-Icom D-Star Repeater. I managed to build my own homebrewed repeater, WX9NC-B 441.95625+, with Motorola CDM-1550 radios, a Moencomm Star Board, and a Raspberry Pi running the G4KLX software using the ircDDB. It works really well. I call it "M-Star" since it is built out of Motorola radios and Icom already trademarked the D-STAR name.

I enjoy HF. SSB, RTTY and BPSK31 are my favorite modes these days. Email me to arrange a sked! If you need any QSL cards from when I was in RI (May 2003 - May 2006), no problem, I have extra cards.

Me gusta practicar hablando espanol cuando tengo la oportunidad en el radio.
