Omaha - Tower 170

[W0JJK]

The Omaha site is at NSP office at 108th and L st. Notice the new antenna's and shortened tower.

Graves what type antenna are you using?

RadioShack's rubber duckie 800 and the normal stock antenna that came with the scanner (Pro-106). I can't test my PSR-800 because its not picking up anything (must have done something to it)

I use vhf commercial antenna on PSR500 and gt Omaha site 50 to 100% in my house in Olde towne Bellevue. I put the stock one on and it does not get more 50%.

Considering I was less than 2 miles north of the NSP tower, I have to conclude that the Omaha site is NOT on the NSP tower, but rather on a tower to the west.

My uncle, who is also a Ham and has been in the radio communications business since before I can remember, suggested that the site _may_ be on the tall OPPD tower north of 180th and West Dodge. The hypothesis has quite a bit of merrit as he's witnessed NPPD and OPPD co-locating communications gear where it makes sense.

That site is on high ground and is well-connected in the microwave and networking sense, not to mention that it's an interconnect point between N-WIN and the overall ORION system.

Just a thought! Anyone have any supporting evidence?

I can say that on my trip to Midtown Crossing (32nd and Dodge), my scanner's signal would jump on terrain when I went east bound.

I will also report that my PSR-800 is working again (some reason it changed my systems from P25 to MOTOROLA). I will be testing this system on the PSR-800 soon as that has better performance on P25 than my Pro-106.

Hey, 'JJK!

Humm.... you're right about the new antennas, so it's hard to argue that it would be anywhere else...

I just thought it was _very_ odd that my RSSI would vary as much as it did when blocked to the west, even though I was only 1 to 2 miles north of the tower at NSP.

Have a GREAT evening!

I recieve the Omaha site at the office at 100% until the 152.480 pager transmitter on top of the hill starts to page out. Could be something similar in your case, a high power transmitter in that area.
