Re: any thoughtssss

Local (daylight) AM signals actually are ture ground wave, where the transmitter antenna induces currents in the surface of the Earth !

Re: Can't Get WJBK Off-Air in SW Detroit

a 26 inch dipole made of # 10-16 gauge insulated wire would work better for "Fox 2" (RF ch 7) than a high priced UHF antenna that is dsigned for more than twice the freq you want !

Re: The Old FM Band 42-50mhz

There was a lot of activity on 30-50 MHz band in my early years of mobile radio repair work. I could hear sporadic E-layer propagation bringing southern State's Sheriff departmant signals into the Detroit area, strong and clear in the summers. Little by little the users migrated , first to 420-450 M...

Re: CFRB Or WINS 1010 On STA? WINS 1010 Dominates In SE MI

CFRX 6070 is alive and well. Just now tuned in with my 90 Ft dipole up 35 Ft in trees. It is reading S9+20 on the FT990 meter. Not bad for 1 kW ! CFRB on 1010 is not doing as well with the daytime D layer soaking up the signal, audible but with QSB (fading) and a best reading about S8, using a 250 F...

WWV gives you updates on the time about every minute or so 😝
It's a bit more accurate than "about every minute". also gives propagation reports and marine storm warnings for shipping. Is also a primary frequency standard.

Re: Could WWV Be Repurposed As A Private Combined News Outlet/Time Signal Like Radio Reloj?

Our govt is not like the one in Cuba (yet) and would not be interested in giving WWV over to a civilian outfit, They would rather just scrap it.
In Cuba all those stations with the same program are also eliminating any signals from the outside from getting to the people.

Re: Rare catch on 720 AM at night

One morning, a lot of years ago, I heard a station giving out traffic warnings during an ice storm in Oklahoma, wiped out 740 in Toronto totally. Seems like a station in Tulsa (maybe KRMG ?) was running the daytime power of 50 kW and daytime antenna during the emergency situation. . Some times you j...

Have been hearing various E-skip (or perhaps F2?) just about every morning for the last week now.
Most likely some E-layer popping up, not going to be any F-layer skip up on that freq range, with the low solar activity..

Re: Metro Detroit CB

Strong enough to be local, maybe commercial paging is trying to reclaim 27 MHz channels.
May be testing a system. When I first started in mobile radio servicing (4 decades + ago), there were a few systems on the 27 MHz range. using legally assigned channels for paging.

When I was 17 I brought the first FM radio into our house, It was a three tube Granco Tuner that I listened to with some qulaity crystal earphones I rescued from my high school language lab, (trashed because of a broken p...
