Thelegacy’s post is just plain wrong, and goes over the line of ad hominem attacks. I was going to Unapprove it (and in fact, did for a little while). Then I saw Carl’s rebuttal, which is by and large accurate and factual. However, it made no sense without the original post being there. So the offending post is back.
I think that it is tim…[Read more]
Besides the 3 hobby radio forums there’s also the 2 on Facebook.
I don’t think the Admin. of the ALPB is acting as dictator as he’s asking for member input on a name and even the separating of the forum and the ALPB. In fact the new name is the result of input from the few members including myself.
I think only 3 people, myself included, bothered…[Read more]
I can also answer some of Rich’s questions, and respond to his comments about ALPB member participation.
I was one of the original members of the ALPB (not original original, but joined a few months in) and stayed until mid last year. That was for a period of multiple years.
The ALPB meetings were always sparsely attended, with a few staunch…[Read more]
An earlier thread referenced time travel and discussed the possibility of its existence. Perhaps this answers the question.
I particularly like that the character in question sold the townspeople umbrellas to protect them from stray meteorites.
Ya, those BV900s were made for gyms where you worked out with headphones and the transmitted music…..guess where it wasn’t a TV set large screen and an FM frequency for sound.
Don’t know if I would want to have 900MHZ headphones on all the time to hear my station.
A simple frequency counter will tell you the transmit frequency if it’s sensitive enough.

And in case some don’t know the song I have been posting the songs here for any interested……https://youtu.be/3D8-NIFo-vY
I think the good thing about the ALPB is the forum as Artisan has informed is staying with a new name, even though there will be no ALPB or if there is it will be a separate from the forum. Micro Broadcasters is a good name and accurate of unlicensed broadcasting.
@ thelegacy….If you got another visit it wasn’t necessarily because someone reported you for something it was because you are on their radar as you were visited once. So follow up checks may happen. Be good with them and they will be good with you.
You are too quick to assume someone is a “narc” and that’s why you got a visit.
Also they didn’t…[Read more]
I thought it was just changing it’s name to and was interested in feedback about new names.
I and a few others gave some suggestions but nothing was mentioned about shutting down. I wouldn’t like to see it close as it would be missed.
Thelegacy, you really have no idea what you are talking about.
You’ve never been involved in the running of the ALPB – I have, first as Forum Moderator and then Chairman when Bob walked away from the position.
You weren’t involved in the behind-the-scenes machinations when Bob came back and decided that he didn’t like what was being posted in…[Read more]
Occasionally I go over to the ALPB Forum to see what is happening. Usually not much.
It now appears that the ALPB is effectively disbanding. It’s been in limbo since the Chairman passed away. Something was said about continuing social meetings, but whether that would be under the banner of the organization is still questionable. The ex…[Read more]
Here comes Oompah Hour #256, ready to go at the usual link:
This week’s lineup includes a rare Frankie Yankovic tune, AND I narrate a bit of the Hokey Pokey written in Shakespearian prose!

Thanks guys for explaining it!
“So, for example, if the d-c input power to an r-f amplifier stage is 100 mW, the r-f input power to it is 2.5 mW, and its r-f output power is 50 mW, then the amplifier has a power gain of 50/2.5 = 20 (13 decibels), and its operating efficiency is 50%.”
That is a big help, thanks.
@ Mark: Answering your question, since the power output is in fact minuscule < 10 mW, and with an unpredictable load impedance, it’s simply easier to specify input power as V * I to determine the power whether it be transistors or tubes. Also, even if the load impedance was fixed acquiring a measurement device at such a low power levels is…[Read more]
Just noticed this is available on Amazon Canada and Amazon .com
It seems a little clearer to me now. Thanks Tim.
Would be simpler if the rule referred to actual power out at the input to the 10 ft. antenna, realistic to what actually gets fed to the antenna.
How did they come up with input unmodulated to the final anyway?
Also what if you got a very high power amp as the final and even with the loss had a…[Read more]
