About the Author’s
Mike Schlamp (W5CUL) was first licensed in 2003 as AD5OX. Soon after receiving his license he
applied for and received his grandfather’s call sign through the FCC vanity system. Despite recently
obtaining his amateur license, he has been around the hobby and other venues of communications for
many years. His first introduction into the hobby was at the young age of 5 as a SWL’er, and later was
tutored by his grandfather in receiver and transmitter theory. It wasn’t until his induction into the armed
services that Mike started working on communication equipment that did not exclusively utilize tubes.
His grandfather was a little biased when it came to IC (rice box) technology. During his tenure in the
active service, he repaired everything from AM/FM/SSB transceivers to microwave & satellite
transceivers. The last four years, prior to transitioning out of the active service, found him deep into
cryptograph cellular systems. This experience ultimately drove him into working for SWBT upon his
departure from the service. He now works for AT&T Labs, formerly SBC Labs, Inc, in their Broadband
Transport Group in Austin, Texas. He is married and has 3 boys, one Eagle Scout, and two runner-ups.
His hobbies are Scouting, Amateur Radio, and Wood Working, in that order.
Jim Thomson (VE7RF) was first licensed in 1972 as VE7AJP at age 16. Prior to that he was an avid
SWL'er between 1969-1972. In 1987 he obtained his first two letter call sign, VE7RQ. He obtained
his current call sign, VE7RF, in the mid 90's. He spent some time working as a commercial radio op for
the MOT in 1974. Later, after attending his local college, he worked for Canadian Telephones and
Supplies, a subsidiary of the then British Columbia Telephone Co. as a Central office equipment
installer. The last 27 years has been spent in Network Operations for both the former BC Tel Corp.,
and now the current Telus Corp, as a Network tech. During his 30 years of employment, he has seen a
transition from electromechanical to electronic analog, to the current digital /fiber networks now widely
in use today. Much of his amateur equipment consists of a combination of commercial radios, modified
commercial products, and home designed and built linear amplifiers with mating HV supplies. He
currently uses 2 x FT-1000-D's, and 2 x FT-1000-MP-MK-V's, all 4 of which are heavily modified. He
also has six linear amplifiers. His interest in ESSB dates back only 5 years. Currently, 14 pieces of audio
rack gear are employed. Other hobby's include jazz, and some gardening. His Spouse and two grown
children support his efforts to enhance and promote amateur radio.
