Same parameters but at 100 mW
So did I get that right it was 1.2 miles? It looks like that would cover some good population and yet on a rubber duck you won't go much ferther than 1.2 Mikles. Probably closer to 1/2 mile for a good digital boom box. That is the range I'm looking at. Was that suppose to be on the 2nd floor of 1st floor? Maybe we could get this. 100mW seems like something we could do for FM because it covers about the same as 100mW AM. Good Job. Now we know.
This never happened so far as I've heard.
Simulation. I know, but hey I didn't hear a damn thing lol. OK we really need to have a meeting as I have a few things we need to talk about and too long to type. I'm afraid to teamspeak the same time as I'm on air for it could cause my station to cut in and out. If I had the money I'd buy teamspeak for my Android wo I could go on with that and talk to you guys. Oh there is a service that is free. Its called Easy Conference. You can get up to 50 people on using your phone. You set up a number and passcode and anyone in the USA can call for FREE. Might have a good use for an emergency meeting where we want to keep the trolls at bay. And we can make more plans and talk about private stuff.
The ALPB Teamspeak server is usually running and for those interested in having an impromptu discussion just pick a time, login and see who shows up. If you pick a time announce it here.

In the early days of the ALPB we talked about having a "private meeting area" as a feature for members of ALPB, but decided against the idea. At the next Meeting we can recall why we think it's a bad idea. It's not fresh on my mind or I'd say more about it now.
There is another hobby website that does have a private meeting area for things they do not want the outside world to know. The KKK also has a secret meeting site.
I have three streams running from my computer and am able to use Teamspeak at the same time without any conflicts.
Also I should state my position on the FM improvement scene... as I've declared at the Meeting I support in principle the upgrade of 15.239 to match the BETS Canada standard, but I do not have time to be an activist beyond announcing that public position.
New Meeting tomorrow night?
Yea we could talk about this stuff Tomorrow at the meeting. Also we can meet anytime in the meeting room to talk about things that come up that we don't really want to talk about online here where the trolls could try and use against us. I don't think there is a problem with just logging in to the meeting room anytime during the day. I'll check in from time to time and see. I'd like to talk about the Pro FM stuff that comes up and questions and what not.
Thanks Carl. Yes, time has again slipped away and I didn't get the notice out but most of us know it's always the 1st and 3rd Saturday of every month.
And so the next regular ALPB TeamSpeak meeting will be Saturday August 1st at 9:00 pm Eastern time.
As mentioned above there has been a lot of activity regarding range testing of various FM transmitters in preparation of preparing a "suggestion" to the FCC about allowing a modest increase of ERP.
In the meantime it's amazing the coveage some are able to obtain at the current ERP level. All it takes is a great location for the transmitter/antenna system. After all, we are currently receiving images from the space probe fly-by of Pluto and I can't imagine there is a great deal of power expended from that transmitter. Anyone know?
If you'd like to join in and are not an ALPB member, simply read The ALPB Charter Document found on The ALPB website. If it sounds OK then download and install TeamSpeak Client 3. There are links to both the Charter Document and TeamSpeak download site on The ALPB homepage.
Once you have downloaded and installed TeamSpeak, let me know and I'll send you the TeamSpeak server address and password. That's it!
There is no commitment, nothing to sign or send in. Just agree to follow the minimal requirements of the Charter and join in.
See you at the meeting!
The "rubber duck" included with the Wholehouse 3.0 transmitter I received 10 days ago is clearly just a short metal wire inside a rubber (actually plastic) sleeve or housing. It doesn't even have an actual "reverse SMA" connector on it. It simply threads onto a bolt. It's basically a 5" piece of wire for an antenna. A rubber duck antenna contains a helix and is tuned to anticipated operating frequencies. I'm sure a real ruber duck on this transmitter would greatly and illegally increase it's coverage.

5 Inch wire is no where close to the wave length for FM. No wonder it takes 100mW to get close to 250 uV/m at 3 meters. It shows why it takes that amount of power to get to that range. And the type of bolt they use you can use anything as an antenna just be screwing the right nut into the bolt. Who would have thought? But such a missmatch can cause harmonics and spurs too unless you have an automatic antenna tuner inside the transmitter.
Yup.
