WITH A CALLSIGN OF K6SEE WE HAD TO PUT UP AN
Our machine is currently transmitting in beacon
mode on 2.442 GHz fm ATV. When inputs are active, they will include 2.412
GHz ( if the actual placement allows this!) Desense in lab test at current
power levels is acceptable.
A 33 cm am input (freq to be determined) and a
70 cm am output (tbd) are currently in the works. Consideration of the existing
Bay Area ATV system , W6CX
Mt. Diablo, will determine our 70 cm input/ output.
Current power level is just over 1 watt to the
antenna with an ERP of about 35 watts. The 2.442 GHz exciter is by FM Technologies with a power am to boost
the ouput to 1 watt.
The 70cm exciter is a PC
electronics TXA5-70c with a Toshiba S-AU4 brick for 10 watts pep output.
Currently, a 2.412 GHz input through a P.C. Electronics
Video Operated Relay board, VOR-2a, keys the 2.442 GHz exciter.
The output antenna is a Comet GP-24, 1/2 wave x
22 verticle (15.4 dBi)
The receive antenna for signals from the west is
a 2 ft dish from MDS service (vertical). Currently receive antennas for
signals from the east are being tested.
Any suggetions and help on antennas for 13 cm would be
HOW DO I RECEIVE THE SIGNAL?
