K6FB Repeater News

 - Dan K6PRK

The social part of LCARC has kind of been in limbo for the past year or so. The biggest reason is probably because everyone has had their noses to the grindstone and has little time for ham radio.

The technical end of the repeater has been quite active and there have been some nice additions to the system.

The club purchased a remote base system several years ago, but we had some technical difficulties making it interface with our controller.

Tom K6KMT and I finally got the remote bases running late last year.

We now have the capabilities to operate the remote bases on 10 meters, 220,440 and 1.2 GHz. All of the remote bases are connected to their own separate antennas.

Last year there were incursions by a repeater coming on 223.88 MHz and 145.45MHz. These repeaters were both uncoordinated and it took considerable effort to get these 2 co-channel repeaters to move to a different frequency pair.

Everything is now clear on both frequencies.

The reason that an incursion occurred on 223.88 was because of inactivity. The repeater was not being used by our club membership and was only keyed up occasionally. Our 220 repeater is now linked to our 2-meter/440 repeaters and will show activity on the frequency.

The amplifier on the 2-meter side had a burned trace on the PC board and dropped down from about 55 watts into the antenna to only about 1 watt. This happened about July 2002. No one seemed to notice it and someone put a repeater on our 2-meter frequency in Shingle Springs, CA.

That new repeater caused some serious interference both on our input and output.

The amplifier was repaired and acted as in incentive for the uncoordinated repeater operation to move to a different pair.

There have been occasions where a spur from the 2-meter amplifier drifts across our input and causes de-sensing and noise. The manufacturer will not repair the amplifier and we must consider the purchase of a new one.

In the meantime the 160 watts 2-meter amplifier has been disabled and we are only running about 5 watts into the antenna. We want to replace the amplifier very soon or the frequency will be in jeopardy again.

The replacement amplifier will run about $600.

Your membership dollars are what help to keep K6FB on the air. When the time comes we hope to count on your renewal.

Except for the amplifier issue the repeater is in great shape.

73, Dan K6PRK
