WTKA is far enough from any major road , it's difficult to spot.
I see 4 towers at WTKA

E-layer can happen any time of day, but it's seasonal.

All I can give you is QRZ.com...Colonel Flagg wrote: ↑Thu Jun 08, 2023 1:54 pmHow about posting a link to that discussion.
Sounds interesting.
I started reading the pages by Carl Smith and got lost in the math by page 40 !

Re: Televes Hi-VHF Yagi
CKLW-TV had a much better signal from the Riverside Dr. tower. Too bad they couldn't have just put a tower or building up there somewhat taller than the Ren Cen. But moving was also part of a Canadian government restriction of Canadian stations appealing to a US audience and advertisers that began ...

When I read the antennas under test were "inside an attic"......Well I made up my mind . THAT'S the PROBLEM.

Re: Hammarlund HQ 140
That was a great, old "Boat Anchor " of a radio. I have had my share of old receivers donated or sold to me cheap as I was growing into the radio hobby. I have had Hallicrafters, heathkit, hammarlund, RME, WW2 surplus of unknown manufacturer, and so on. Sometimes a beat up, rusty, dubious looking ra...

AM directional arrays
I saw an interesting discussion of phased vertical antennas. On QRZ.Com/ sub Antennas towers etc.
Lot of the engineering hams jumped in with modeling software graphics.
Reminds me of my study of AMBC tower arrays in my youth !

Re: FM DX e-skip 5/31/23
I lived in Livonia from 1949 to 1963, In about 1961 I got a three tube Granco FM tuner and connected a twinlead dipole that I tacked to my bedroom wall. Heard and sent reception reports to distant stations all over the map. Got some QSL cards and letters frm ON, W.MI, OH, IN , IL etc. This was long ...

Re: Alternate FM channel use in Canada
I don't think directional ants are used for protecting other stations on FM like they do on AM ??

Re: FM Transmitter Range
Who mentioned hiding tha box and antenna in a tree on state land. ? This 1000 W transmitter will need a 20A #12 Romex power wire going to it , assuming about 2 kW of 120 VAC power to generate 1 Kw of RF output.power .
I sure would leave a $1000+ of gear behind ANYWHERE!

Re: FM power in different areas
When I was a kid I had some books about broadcasting engineering, there were several charts showing signal strength for various distances VS antenna height and power, in the FM band. I converted the data to show how the signal strength varied with distance with low height and high power and vicevers...

Re: Seeking Receiver recommendations
I also have a Tecsun 880 and believe the small size can not accommodate a decent AM ferrite stick antenna ! It is sadly lacking in AM and LW sensitivity. For Short Wave listening , it can make up for the poor AM/LW. You can plug in a coax fed antenna or just a wire of 20+ ft and really pull in some ...

Re: FM power in different areas
Power Answers Most chicago FM transmitting is done from a few buildings a thousand ft tall or more, The FCC has a chart that shows required power Reduction when the antenna is over 500 ft tall for Class B and C stations. This is to Give an equivalent signal level at a certain distance from the tran...
