Topband: A Tale of a Successful 160 meter RFI Hunt

[donovanf at starpower.net]

Hi Mike, 



Ah... The sweet sound of silence! Now if only there were some 
Topband activity,,, 


My county Office of Emergency Management was very responsive 
and took their Travellers' Information Station off the air this 
morning. Their TIS transmitter has been trouble free for many 
years. Hopefully they will take due care with repairs and testing 
before activating it again. 


The on-line FCC database shows only one TIS station in the Atlanta 
area, but its at Atlanta International Airport far from Ken's QTH.

I wouldn't limit your search to 1/2 mile, you should search at least 
two miles. A large loop antenna should serve your needs well. I've 
found the Tecsun PL-660 to be an excellent and inexpensive RFI 
hunting receiver. 


Good luck!

That is interesting Frank as I was just at K4TEA’s QTH yesterday trying to find why he had more noise from one direction that had no signature of any type, just higher background from 1.7 Mhz up to around 2.5 Mhz. 80 M is fine. He is near an interstate so maybe there is something similar out there. I built a large DF loop for 160 I can haul on a pickup to use with my K3. We moved from location to location trying to triangulate on it but we felt it was going to be within .5 miles but I see your source was 2 miles away. Thanks for the input. Keep us posted on your success on getting it turned off. 73 Mike K4PI
