The original 378 foot WJJY tower is on the right. The new 498 foot WJJY tower is on the left with a new Electronic Research broadband FM antenna in black radomes near the top of the tower. About half way up is an ice shield over the STL dish. This new tower and antenna were constructed during the summer of 2001. They are currently being used for WJJY FM at 106.7 MHz and KBLB FM on 93.3 MHz. Both are 100,000 watt stations. |
 |
Here is the new WJJY/KBLB transmitter building with the M. W. Persons service van parked in front. The facility was completed in December 2001. |
 |
New utility power transformers had to be installed to handle the increased electric load for the second station. Here, utility workers connect primary underground power. |
 |
A Continental 20 KW FM transmitter, on the trailer, is delivered to the site and offloaded by Electricians and Dave Cox (on the right). |
 |
These two Collins/Continental Transmitters started out their life as 20 KW units. They were retuned and upgraded to operate on 93.3 MHz and 106.7 MHz at 25 KW. This was an interesting project that involved a number of updates in the design. Note the 10 foot high transmitter area and no ceiling. Hot air, from the transmitters, collects in the upper area of the building interior and is vented by 5 fans on the gabled ends of the building. |

(l-r) Jeff Taylor
and Mark Stapleton of Electronic Research doing final installation of a 4
inch rigid transmission line to the six cavity combiner system for the two
stations.
In addition to being well trained with a network analyzer, Jeff is a certified welder. He helped make the custom pieces of transmission line that were required in bringing the antenna feed to the combiner system. |
 |
Here is your intrepid Radio Broadcast Engineer Mark Persons again looking at the completed two-station combiner. Each station goes through a 3-cavity band pass filter before going to a T in the middle and then up to the antenna. |
 |
A 100
KW electric generator plant was installed to take the station through
electric power outages. This plant will run both broadcast
transmitters at full power and still have headroom to spare. It has
a turbo-charged Ford V-8 engine.
On the left is Al Hauser from Caterpillar in Duluth with Mark Persons, WJJY Corporate Engineer. The photo was taken when the generator was commissioned on December of 2001. |
