Re: [IRCA] 740 KBRT heard in Michigan

Hi Tim

They did test their new transmitter once or twice some weeks back, but are planning to make the big switch on the 28th of this month.  Also I think their new transmitter would be a tougher catch there - it's directional aimed mostly out west over the Orange County area (and also L.A. somewhat but not as much) and out to sea.  The Catalina transmitter is (soon to be was) directional aimed inland, so from what I'm guessing (haven't actually looked at the mV/m @ 1 km numbers on the FCC data, but have looked at Radio-Locator coverage map and FCC pattern graphs) actually sends considerably more power toward you than their new transmitter.

They commented that when doing a drive test of their signal, it was noticeably weaker in the San Diego area.  I expect it'll definitely be weaker where I am, especially, considering where I am in the pattern (I'm a little more inland and east.)  It'll be interesting to compare it to 830 KLAA's omnidirectional 50kW signal (their stick is just a few miles on the other side of state highway 91 in that area.)  Once the switch is made, I expect 1070 KNX will be the strongest station I hear from the L.A. & nearby area in the daytime.  With KBRT on Catalina Island, they have KNX beat by a couple dB or so.  KFI is in 3rd place, followed by KLAA and KLAC (5kW on 570, not sure at the moment which is stronger as I'm too busy listening to 1110 KDIS right now.:) )

73, Stephen

1043-1151+ UTC, 740 KBRT in and out for the last hour or so, sometimes
dominating 740 for several minutes at a time.  I've recorded several
nice IDs already.  I'm guessing that this is from their new transmitter
location on the mainland (50kw now?).  Go get 'em!
