I have already mentioned in another post that your problem may be
unresolvable as normal phenomenon. In fact in the Greater Los Angeles basin are there are numerous repeaters on every frequency (CTCSS tone protection required) and it is considered "Liddy" to DX repeaters as it ties up local co-channel or adjacent channel repeaters. It should be noted that our co-ordination body inverts the input/output pair for adjacent 15 kHz repeaters for that reason. Your best bet might be to use a 22 element or longer beam with greatly reduced power. I routinely keep the TS2000 set to 5 watts (lowest) rather than 100 watts and use a beam because I have some elevation. For your peace of mind, I am a certified technician (NABR, GROL, PCIA) with many years experience with Motorola, Kenwood, Icom, Yaesu, BK, Midland and numerous proprietary systems. I can perform diagnostic testing and corrective adjustments or repairs of all key performance parameters, including before and after documented measurements for the mere sum of $50, ship to my address with prepaid return. Please ship in sturdy box, wrapping unit with microphone in order to provide a minimum of 3" of bubble or Styrofoam packing (no shredded or crumpled paper, it will settle in shipment). If there are serious malfunctions that would be beyond that flat rate, there would be no charge at all pending your approval. Payal is preferred because it works and provides card services that are safer than your local stores. I personally perform and guarantee the work myself and that my time is not subsidized by crime, your taxes, or any conspiracy to subvert the US economy. J.

I like to talk to the 146.700 repeater in Pratt, KS (about 95 miles). Problem is that when I transmit on 146.100 for the Pratt machine, I inadvertantly also key up the 146.715 machine. At first I suspected my transmitter was off freq so I tested 3 other repeaters - 145.370 at 1/2 mile away, 146.895 at 1 mile away and 146.850 at 3 miles away. On all three tests, I could key up those machines as long as I was +/- LESS than 15 khz from the correct input freq. On all 3 when I went to the next channel (15 khz spacing) up or down, I could not key up the machine. I also did a simplex test with an OP about 1/2 mile away. I tx'ed DTMF #5 for 30 seconds while he moved above and below my freq. He reported he lost my signal as soon as he got more than 10 khz from me. He also reported that the signal levels at 10 khz were equal between + and - . All these tests were done with a known good antenna & new CQ-102 coax. Rig is a 1 year old Kenwood TM-271A. All tests were done at an indicated 68 w which is about normal for hi power from this rig. I'll refrain from using the Pratt repeater until this is fixed. My question is this - have I done enough to assume that the problem is not on my end? Sending in my rig for service monitor testing would be difficult & a genuine pain in the neck. Ken KG0WX |
