Re: FM reception in the southeast part of the US

I picked up WLW in downtown Plymouth back in the 90's. AM (WLW) and FM have totally different kinds of propagation beyond the normal service areas. AM radio (Medium wavelandth) can travel long distances via skywave where the signal hits the ionosphere hundreds of miles up and is bent back to Earth ...

Re: FM reception in the southeast part of the US

Something to consider ; South Florida and the Gulf coast is pertty flat land with no hills or mountain ranges to block the line of sight! When I was in the mid Fl Keys I could hear many steady FM signals from Miami (90 miles) and even a rare few Tampa/St Pete (200 Mi) stations intermittantly. I was ...

Re: Crawford WMUZ AM Antenna Array

YES, That large array is quite an antenna for 1200 WMUZ ! I have checked it out on Google Earth and driven to the area to eyeball it. The company that I worked for, in Chicago, also acquired 1200 kHz as a NEW frequency for that area and built a large array on the far south side , beaming up through...

Those NDB beacons were my first Morse practice signals when I was about 13 years old! Back in the stone age !

Re: Visit America's Last Morse-Code Station

DONT FORGET, there are literally millions of individually owned and operated Amateur Radio Stations around the world. They can use Morse code on the CW mode of transmission if they want to . Thousands of those operators belong to various organizatons promoting the use of Morse Code on the air ! Most...

Re: Tropospheric ducting on Saturday 2/3

Wow. I can't believe I was getting a translator from Holly in that area, and enough to fight with a Lansing station that generally comes in reliably in my area. The "Holly" translator is actually across US24 from Dixieland Flea Market on the Waterford/Pontiac border, NW of downtown Pontiac (last I ...

Re: Tropospheric ducting on Saturday 2/3

Reading this thread makes me want to get an antenna back on the roof and get my semi-retired Fisher tuner back in service. Had some roof work done and the people took down my big antenna tripod . Maybe this spring I will get the 3 Meter dipole back up. Spending all my free time on the higher freq HF...

Re: AM Civil Defense pre-1963

I recall being shown the mechanisms in the AM transmitter and antenna tower tuning sheds, to change WXYZ's freq from 1270 to 1240 for Conelrad.We updated the monitor reciever from tube to solid state and I got gifted the old tube reciever.

Re: Better sensitivity/selectivity from new RF DSP Chip

I guess a do-it-all radio would be very expensive, I could live without The FM band and all the digital data you can pull out, give me a good long wave, AM, SW radio I can afford. My TecSun portable suffers from proor AM and Long wave due to the size of the intermal antrenna. FM and SW bands seem to...

Re: Better sensitivity/selectivity from new RF DSP Chip

From a Quick read and look at the manual presented.
I am guessing it does not support SSB/CW operation on the shortwave bands.
Not having that function limits severely what you can listen to on the SW bands/

It Will NOT be on my XMAS wish list.

Re: CKWW 580 Signal Observations

Is WJR running the power saving type transmitter now too? Might explain weird S-meter readings in addition to about 5KHz filtering and whatever crap they use for ratings transmission. CFCO never disappoints, and they did have a null at one time to the SW clipping Toledo a bit. WWJ is hammered with ...

Re: History of WLW

GREAT EVALUATION OF POSSIBLE DESIGNS. Sometimes the cost of many towers colors the final designs. Like the WXYZ AM antenna in Southfield.using two towers to do what three usually did. :shock: :D
