Chelsea Yaesu DR-2X Repeater Setup
Wesley Cardone, N8QM
July 3, 2022
14.
The water tower
a.
Schedule a visit to the water tower to install the repeater there.
b.
Ask if it will be possible for us to make a vector impedance measurement of the antenna
at its input at the top of the water tower.
c.
Inform the water tower that we would like to have three (3) visits in the immediate
future.
i.
Visit 1
1.
To install the repeater
2.
To make vector impedance measurements of the antenna input at the
water tower top if permitted. This measurement will be used by Wes to
design a tuning stub to optimize the repeater output.
ii.
Visit #2
1.
To install a tuning stub
iii.
Visit #3 (optional if needed)
1.
To remove or make changes to the tuning stub.
15.
Perform varied testing for learning purposes while we wait for water tower installation
a.
Get some metrics over the next few days on the difference between
i.
Power out:
1.
LOW,
2.
MEDIUM, and
3.
HIGH power output.
ii.
Squelch
1.
RX and TX Squelch options
iii.
Other things not thought of earlier.
b.
Make some decisions on refinement of repeater programming that are not available for
change by remote.
16.
Visit #1 at the water tower with equipment
a.
Install the repeater at the water tower
b.
Make vector impedance measurements of the water tower antenna.
i.
At coax connector at water tower base
ii.
At antenna input on top of the water tower if permitted.
iii.
These measurements will be used to design a tuning stub for the antenna.
c.
Confirm that the repeater works as programmed.
d.
Confirm with the water tower person that we plan these visits in the next couple of
weeks as requested earlier.
e.
Assure the water tower person that our intent is to minimize our visits to their facility.
17.
Visit #2 at the water tower
a.
Install the tuning stub
18.
Visit #3 at the water tower (may or may not be needed)
