Re: Ever Hear Of A Rotator?

Those are mostly ham beams. Bottom is 6 meter. The next two are 2-meter, then it looks at 440 MHz, 220, 440... Ha Ha Ha, kidding? those are single channel VHF TV and top is UHF FOR TV reception. Y. Pretty efficient if you know exactly what distant stations hyou want to see. My 6 M Yagi has elements...

Re: WWV / WWVH

I've been going around resetting the clocks for DST. WWV is weak on 10 MHZ. On 5 MHZ I'm getting a good signal from WWVH, with a weaker WWV in the background. I have one clock that I never have to change, it sits on UT all year. by the way some of my clocks have an auto set feature for daylight sav...

Re: WWV / WWVH vAND

Some late evenings WWV is strong on 2.5 MHz and stronger on 5 mHz, not very good on 10 , and gone on 15, 20 and 25 MHz, some days you can hear it on 20, and rare E-layer openings it gets real strong on 25 MHz. I have heard WWVH on 5, and 10 at night, have heard them on 15, 20 and 25 in the afternoon...

Re: TV FM Antenna Nostalgia

I just bought a rotor for my HF and VHF small yagis (50 and 28 MHz) that is a few steps above the small TV antenna models, cost near $300 plus shipping. Some of the Bigger HF antenna arrays need a rotor with some horsepower, costing over $ 1000 ! For a while I had a small TV rotor for my 6 elememt F...

Re: Are You Sure Your "Upgrade" Is Really That Dramatic?

That ABBA song was a Great one to play on that new 100 K signal ! The girls in that group had very bright sounding voices ! A few years back I heard that the blond, Agnetha Faltskog had come back and recorded again. the CD Title was "A" so I bought it. She has had to relearn singing and the more mat...

Re: WWJ signal problems? (+ WJR audio distortion)

CKLW 's 5 tower array is way down south of Windsor, between Amherstburg and Harrow.
A lot closer to Toledo than the big Detroit AM sites.

so sorry spoke too soon, CK is actually a few miles farther from Toledo, than WXYT and WWJ, ! Just a few !

Re: Scanners

dipole wire should be insulated if you are worried about fire or detuning by touching odds and ends in the attic. bending ends around a corner is OK but just not bending back against the rest of the wire.
Best advice ...Move to where you can run your antennas up high in trees !

Re: WWJ signal problems? (+ WJR audio distortion)

My field strength list is a direct measurement . The order is pretty close to the theoretical (?) values in the VSoft list. First and second place is from a nearby Transmiitter site . THE METER READINGS ON THE TIED STATION VALUES were within less than a half S-unit/ I can blame the discrepancies on ...

Re: WWJ signal problems? (+ WJR audio distortion)

Last Night I drove from the Straits Area to the Detroit Area on I-75. The WWJ signal was bad most of the way. WFDF 910 was a lot stronger nearly every time I checked the two. Really, they ought to put a 5 kW-ND AUX back at 8 Mile and Meyers for when they have transmitter problems. It would serve th...

Re: WWJ signal problems? (+ WJR audio distortion)

Strogest Carrier signal. Here is my list of today's measurements from 10 Miles West of Pontiac, MI. Maybe not loudest but highest carrier signal level, Measured with a Yaesu FT990 , using a dipole antenna cut for 1820 KHz (with 150 ft of RG8/U type feedline) I used the 20 dB attenuator to tame the ...

Re: Scanners

All my scanners have mode locked to range of freq, AM for Aero band and FM for all others. You only find CW/SSB is on 6, 2 and 3/4 Meter ham bands . BUT on most scanner type radios,you can not go to the SSB mode. The really good Receivers that cover HF and up to VHF/UHF, With any mode selectable, ar...
