broadcasting to the dummies

May 7, 2013 by rock95seven

With all the commotion about alleged shut downs, inspections and what-not i had a serious thinking session about what to do with Rock 105.3.

Do i want to continue to pump 1 or 2 millliwatts into a 0 db folded dipole and risk a visit or letter in the mail ? Or should i just run a part 15 certified fm transmitter with it’s short antenna (it’s 5 inches) and make due with the woeful 150 feet of transmission range?

The second option sounds pretty safe, however the first had more coverage. Why?
Because it was a Ramsey FM 25B set at 2 mW into coax leading up to a folded dipole 15 feet above the ground.

That set up covered just barely a 1/4 mile to the north of here and 1 mile south, west and east to a factory car stereo. Sounds ideal doesn’t it? But wait a minute, fcc rules for part 15 clearly state that range on a legal (certified) fm transmitter or even home brewed should have a limited range of 250 feet. 

In my situation 5 homes surround my home and are anywhere from 12 feet to 70 feet which i like to call my captive audience. Whether they listen or not they are more likely to hear my station no matter how many mW i pump into a dipole or a short wire antenna. 

As we have all seen in the past and present actions from the fcc some operators were busted, while some were given some tip’s by the fcc agents and when everything was kosher the agent went back to whatever it was they had planned next.

And it has been said over and over again that some fcc agents are easy going , that they will allow the stations to continue to broadcast as long as the operator made a few changes. One good example is a station in Florida but i will not be naming names here out of respect for the owners of said station. 

Some changes were made to that station per request of the field inspector and after those changes met his or her satisfaction, the station was allowed to continue broadcasting.

Other part 15 stations were not so lucky.  
So option 2 looks pretty good. It’s safe and i guess we could make a whole new catagory of broadcast modes for our hobby. Call it Minicasting as opposed to Microcasting which seems to have an iffy definition to it. When i hear that word i actually think to myself “yeah they are pushing more than the legal limit” .

I say that because 9 times out of 10 that station is actually pushing 100 mW to 2 Watts on f.m. and before you know it they are on the fcc’s list of violators. 

It is my opinion that the field agents should treat every station the same. 
One agent should not be allowed to say “eh lower the antenna and i’ll let you go” while another say’s ” i don’t like what i see on the field intensity meter shut it down and hand it over” “you’ve been served”  Every field agent should treat each station ,wether it is licensed or not the same way with the same aggression as the next.

Full powered licensed stations break the laws just as much as the pirate’s.
At least some of the pirates and part 15 stations carry some good programming.

So maybe we should all just connect to a dummy load and be greedy with our signals. Keep the signals within our homes and never even mention that we put a lot of time and effort into our tiny hobby stations. 

Another thing that bugs me, while part 15 fm is limited to 200 feet and it’s power is measured by field intensity what would become of part 15 AM ?

The rules also mention a limit of 200 feet even though the power is measured differently the limit is still stated in the revision made back in 2000.  
What if an agent decided , hey you know what? i think today i will excersize my authority and streatch the truth a bit. Hey buddy , your station is being heard a mile away on 1620 khz i am afraid i am going to have to inspect your station.
Yes just as i thought, you are running too much power. Yes, i see the certification sticker but your limit is 200 feet. Shut it off and fix it or i will take everything you have right here and now.

See we need that kind of enforcement but on the other hand, if all the agents do their own thing regardles off protocol then enforcement will fail and radio will continue to be the  big mess it is today. 

So with all things considered, i think i will safely broadcast the 200 foot limit and be content with the 25 to 30 homes i hope can tune into my minicaster.

It sure beats russian rulette.

Tuners and 3 meter antenna’s

February 13, 2013 by rock95seven

Just out of curiosity, wouldn’t a tuner such as the one made my MFJ Enterprises work to take place of the loading coil of a 3 meter antenna on the AM band? If so i think it would shorten the hours of fine tuning a coil and antenna system. What do you think?

My Apologies

January 2, 2013 by rock95seven

My apologies to the group. The opinion i shared in a thread is one i should have kept to myself. I just felt the need to voice my personal feelings in the forum but later after reflecting on my comment it reminded me of my old CB Radio days when a CB Rambo would run 1000 Watts keying over people, being a real nuisance to good radio operators. Eventually i learned to change the channel and ignore those CB Rambos. This is what i will do again but not a 2 way radio but rather online. If i don’t like what i read or hear, i can always change the station or just ignore things i don’t agree with.

On a less serious note, have a great 2013 everyone.

Saying good bye to a dear friend

May 4, 2012 by rock95seven

This article i am sharing with you is about a school program where i received my training for Radio & TV Broadcasting. Scarlet Oaks Vocational School is where i took this course the last two years of High School. Scarlet Oaks Voc. School is located in Sharonville, Ohio and caters to many vocation’s such as culinary arts, law enforcement, computer aided drafting just to name a few. Scarlet Oaks is a branch of a number of vocational schools operating under the name Great Oaks Vocational Schools. The various branches teach many vocations and offers students a hands on approach to real life training.

Scarlet Oaks owns a radio station operating on 88.3 fm with 175 watts and shares it’s frequency with WAIF-FM Cincinnati Ohio.
The school board announced they will be pulling the plug on the Radio and Television program which has been operating since 1979. Apparently other high school “student operated” stations have already closed down and WJVS-FM will be no different. I learned valuable lessons those two years at WJVS-FM and made some great friends along the way.

I will truly miss the program and the great WJVS-FM.
Here is the article:http://cincinnati.com/blogs/tv/2012/04/30/scarlet-oaks-wjvs-fm-signing-off/

alright stop, collaborate and listen..

January 23, 2012 by rock95seven

After reading http://www.part15.us/node/3302 Texas part 15 tour and http://www.part15.us/node/3298 Florida part 15 tour post’s i couldn’t help but wonder, has any of the part 15 stations in Florida or Texas ever considered creating a cluster of syndicated stations?

That is carry the same programming, creating a network out of their part 15 AM stations even taking turns providing programming for their network?

It just seems like it would be cool to have other part 15 stations in the same state not necessarily in the same city carry a network feed all over the state.

If i knew of other part 15 stations in Kentucky i would attempt this myself. Sort of what was proposed for the LW project.

Just a thought..

Yo, we out of here. Word to your mother…lol
