The Repeater

The K4JBV repeater is one Six Repeaters that are a part of The Northern Kentucky Repeater Association.

K4JBV repeater operates on a VHF frequency of 146.895 mhz TX and 146.295 mhz RX. The tx transmits a 100.0 hz pl tone. The equipment is a General Electric Master II transceiver. The receiver has the factory ultra high sensitivity preamp.The transmitter has an output power of 100 watts. There is an ACC RC96 controller which performs all of the control functions. Also a Hall RV4 voter selects the remote receiver with the best signal and retransmits that signal. The voter votes very quickly and may switch receivers many times during a single transmission.

The VHF repeater antenna is 100 ft high atop a self supporting pole behind Bill, K4JBV's garage.It is fed with 7/8" copper heliax cable.

Signals are received at the VHF remote receiver sites and are then retransmitted on UHF to the repeater site where they are compared in the voter with the main receiver and the best signal is fed to the transmitter to be retransmitted.

There are four remote receive sites. two in Independence, the main site receiver and another at 60 ft on a tower along side Bills house, One on the Erlanger PCS tower at Commonwealth Avenue and I75 at 150 ft and the fourth one is located on the Alms Hill Apartment building in Cincinnati, Ohio at 175 ft.














The Main Site




The Trustee

My name is Bill Martin K4JBV and I have been a


Ham radio operator since 1956 when George Reed W4TCO (deceased) first introduced me to ham radio. I was 13 years old.

I passed my Novice class  test and was on the air. I wanted voice privileges and soon upgraded to Technician Class within the first year.

I was 21 when I finally upgraded to General class. It wasn't until 1994 until I upgraded to Advanced class and a week later to Extra class.

I built my first repeater in 1974 the 146.86/26 repeater. It started out on the water tower in the Devou Park in Covington, KY and was later moved to The Northern Kentucky University and after a merger with the Northern Kentucky Amateur Radio Club the frequency was changed to 147.255/147.855.

Then with the help of others. I put on my second repeater the 147.375/147.975 repeateron the water tower in Walton, KY. Then in 1986 the third one went on 146.895/146.295 at my home as a low profile machine. It was later moved to my new QTH where it is now after the 100 ft pole was erected.

The Autopatch ( The Autopatch is Temporarly Disabled)

I believe that an Auto patch should be open to all who would like to use it at no cost. However someone has to pay for the phone line. So use it for emergency calls, or for any other calls you may like. But if you use it on a regular basis. I would expect a donation to help to offset the cost of the phone line.

Since I only have one phone for my residence and the repeater, when trying to make an auto patch, if the line seems deadhang up the patch. Since the phone line is in use.The code to turn on the auto patch is * and to turn it off it's  #

To make a call to my residence for example dial *356 2115 without a pause the repeater will say auto patch and read the number back to you 356 2115. You will then hear a beeping while the controller dials the number and it will then ring.

Please don't abuse the auto patch. and if you use it regularly please donate to the cause. Thanks.
