Repeater

(Scroll all the way to the bottom to see the repeater approximate coverage and technical information)

Once more, at the insistence of my students, we set up a UHF repeater on top of the school roof.  I need to mention here that this small group of enthusiasts keeps me on my toes about the hobby.  First it was the classes they asked me to teach them, then installing a repeater, next they already told me they want to have a Foxhunting contest.  In my life did I think I would be a trustee of a repeater, much less this early in my career as an amateur radio operator.

My first group of students who got a license in 2012. Thanks for being such a great group!

The repeater works on the user side on the frequencies of RX:441.600 and TX:446.600 with a CTCSS tone of 114.8 both for receive and transmit.  You may set your radio to these frequencies if you are ever in our area.   The equipment is a Kenwood TKR-820 donated by KB2MFS, the antenna is a Decibel Products DB-420 donated by W5FN (special thanks for tuning the whole machine to specs), the system identifier ID-O-Matic-II donated by WB6TXX, 100 feet of Heliax cable donated by WA7JAW, and all the connectors and lightning arrestor donated by WN3A

Not exactly part of the repeater, but also to be used WITH the repeater were some brand new HTs donated by NH7QH and K2CEM. W0EP gave a cash donation to get the club started.

Pictures will come when the repeater is all completely in place.  A blog entry showing how we received all this wonderful equipment is here.

 

Not part of repeater, but used with it.

 

 

Following is a picture of the repeater coverage.  The green area represents the strong signals, and the yellow area represents the weak signals. The repeater is a Kenwood TKR-820 working at approximately 11 watts, antenna is a DB-420 at 45 feet high from the ground with about 9 dB gain, and the feedline is a Heliax of about 30 feet long as the repeater is located on a second floor.
