Notice to all Buzzboard readers & posters: A requested server migration took place Saturday evening. Unfortunately, I did not re-point my DNS records to the new server until roughly 7:45p ET on Monday, November 12. As a result, any posts and new user registrations occurring between the nighttime hours of 11/10 and approximately 7:45p ET on Monday, 11/12 have been lost.

This was unavoidable, and the longer I waited to re-point to the new server, the greater the number of posts that would've been lost.

Please feel free to resubmit any threads / posts you created. They will NOT be lost this time! Many thanks for your patience these past couple of weeks while I've worked to migrate the Buzzboard to a more secure, more robust platform.

Re: FM Broadcast tech failures (FMX)

The modulation and equalization on National Weather Service AND Travelers Information Service is horrible. It is difficult to listen to, and so grating on the ears. Are they afraid that people would just listen to those if they made it sound like FM, or even AM, radio?

Re: CMU Sells Flint WCMZ-TV In FCC Spectrum Auction

The neighboring signals are all 40 or more miles away. All of their stations are now UHF, doesn't matter what channel they call it. Just the curvature of the earth makes them iffy. How they get the idea that those other three they mentioned having anything more than weak fringe OTA service makes me ...

Re: CMU Sells Flint WCMZ-TV In FCC Spectrum Auction

Wow. This is crazy. That signal could be sold to a commercial broadcaster as there is no "Educational Band" with TV. You plunk them, wherever. This should be the same with Radio, as is done in Canada. What would you do with it? Every major network is covered. They must've really wanted the 14 large...

Re: New VP at Cumulus Saginaw / Flint

Chris Monk was at Northern Star Broadcasting right after the first time Del Reynolds sold the group of stations he owned, and right before the first time Chris Monk went to what was then Citadel.

Re: Recent Video WKMF/WFNT/WGMZ/WCRZ Former Owner George H.

I remember listening to WKMF 1470 sign off quite a few times, when they were 24 hours a day for 5 days a week, and signed off for maintenance on Sunday and Monday mornings. The sign off tape was voiced by Dick Bing as I recall. About 1968, I remember that the sign off tape said WKMF was owned and op...

Re: Counterpoise pointers

In the 178 degree Day direction, the Augmentation is 1420.50 mV/m @ 1 km IDF with a span on 40 degrees. The Standard Pattern is 1140 mV/m @ 1 km in that direction. 1420.50/1140=1.24605. The power necessary if it were at the Standard Pattern value would be 5000*(1.24605^2)=7763.23 watts to get this a...

Re: Counterpoise pointers

There is Augmentation to both the Day and Night Patterns. To the South, in the Day Pattern, it's quite a bit. Not sure if this has anything to do with the limited number of radials. There's considerable variation in the Nondirectional proofs in various directions also. Equivalent to some directions ...

Re: Counterpoise pointers

It seems like I've heard of people adding screens near the tower base in areas where the conductivity is really bad, like in Western and Northern Michigan (not shown on M-3 Maps) but these are at ground level or buried like radials. I guess the idea, Rich or others can correct me if I'm wrong, is th...

Re: Counterpoise pointers

If a ground system has a certain number of mirror image planes, the way it behaves has that same behavior. The four radial X has two mirror planes, and a rounded rectangle behavior, eight at 45 degree angles would have four mirror planes, and a rounded octagonal behavior. In free space with "spheric...

Re: Spent a week one day in Detroit

jry, I've posted in the engineering section on this. There is no such thing as a free lunch. I suspect that it is the NUMBER of radials, not that they are above the ground, that affects the pattern. Perhaps 12 to 72 radials per tower for a complex DA, depending on MEASURED performance, would suffice...

Re: Counterpoise pointers

My educational background is extensively Applied Physics related. In Physics, they talk about "symmetry" a lot, particularly in regard to Electricity, Magnetism, and Electromagnetism and Waves. 120 radials per tower has a lot more "symmetry" than four radials per tower in a X arrangement. I don't do...

Re: Counterpoise pointers

I'm curious about the measured Night pattern on this. There are few radials and many very deep nulls in the pattern. Day pattern not so much. Two very shallow nulls, equivalent to 1 kW. Third minimum even more shallow.

Re: Skip today?

Got an e mail from Finland the other day. They sent an air check of WSNL.... The low end of the dial is rare over there. I told one of the DX-pedition organizers to try for WFLT also, as the IDF from the DA exceeds WWCK, which they have heard, in many directions except South and East. They also hea...

Re: Skip today?

Ann Arbor has some interesting terrain shielding that helps DX in some directions in some areas. One area near the Gandy Dancer on a hill off Fuller has terrain shielding of stations to the South. Art Vuolo's local Radioguides showed WWWM 105.5 as the dominant station on the frequency, a near local....

Re: Skip today?

Yup, was just some slight tropo enhancement due to the front passing through. Fort Wayne can be had daily on FM from the Ann Arbor area in the spring and summer because of what I assume to be all the humidity in certain levels of the troposphere. I regularly receive the NWS transmitter from Angola ...
