- Stop and get out of the vehicle when I encounter a spike. And have a good visual of the area - if possible. Take some pictures, and note things like weather conditions (skies, wind, temp, humidity), and note the pole number (if there is one).
- Get out a VHF/UHF antenna and swing it back and forth, up and down, and all around the suspected site to try to get a closer indication of the problem source.
- Get out an Ultrasonic Parabolic dish and hunt around the area detected by steps 1 and 2 above. With this type of device very often it's possible to narrow down the offending source to within about 12 inches. Depending on the dish, and specs of the device.
In order to accomplish steps # 2, and 3 above I've ordered these items.
- An MFJ-5008 - "Ultra-Sonic Receiver W/Parabolic Reflector, 40-kHz, Portable, 9-Vdc" which can be found here and HERE - While this device doesn't have many if any reviews on it that I've been able to find, it's price-point as an entry level ultrasonic dish for this purpose seems like a good place to start. (Even though I don't like a lot of the stuff MFJ sells, some of it is absolutely perfect for a given task, and I'll give them the chance on this one). There are others like the one Midnight Science makes called an RX-3. But it's a bit over 2x the price I'm paying for this one. And has semi-mixed reviews.
- Arrow II Hand Held Portable, Item# 437X14
- Alaskan Arrow Satellite Antenna with Split Boom and Duplexer, Item# 146/437-14WBP
- Male SMA duplexer instead of BNC, Item# MALESMADuplexer
I do reasonably well on 50 Mhz here in Missouri. However, I *KNOW* that folks are hearing me that I'm not hearing due to this local noise problem.
Anyway, I just wanted to post about the next round of items I'm intending to try to use and why.
