Our dell showed up and is loaded with win xp pro (ugh) and is currently running winamp for the time being. The station sounds great with a few plug-ins for sound control. The stations signal is pretty sweet too, considering our antenna is inside our mobile home, wich we all know is a tin can.
Aside from the metallic obstacle we have a signal that covers 1/4 mile to 1 mile at it’s best. After that the signal covers a mile with considerable fading.
Im impressed so far with the fm25b my earlier stations used the fm25a.
It was good but i believe this transmitter is by far better.
More news later.
Be careful
I don’t want to be a nag but if you are getting a 1/4 mile to a mile you are not running under part15 FM if you don’t want to run into any troubles with the FCC I would change your power so you
are getting 200-300ft range. If you are looking for better range I would go on part15 AM. If it doesn’t matter to you if your running legal make sure to not get caught!
It would depend on the receiver
A lot would depend on the receiver, but 1/4 mile range *should* be possible on FM within the legal field strength limits.
I’m starting another thread for that topic, though.

Tin Cans Are Poor antennas
Considering i am stuck with my antenna inside a mobile home, i figured it was pretty dam good.
The fm25b to my knowledge isnt capable of doing more than 20mW or less if you lower the output by adjusting the voltage inside the transmitter. I believe the power limit for part 15 fm is 10mW.
I can lower the voltage and lose some coverage and remain legal.
Bear in mind too that most car stereos are more sensitive than alot of radios bought for home use at your local walmart.
Our 1997 pontiac transport uses a dipole antenna on a factory car stereo, wich is more effecient than a straight steel whip.
I have every intention of remaining legal despite the obstacles.
As for part 15 am, i doubt it would be feesible to operate a transmitter on am in a mobile home. Not to mention the rf flying around the house, lol.
Maybe i just hit on a good design for a fm antenna, it certainly did not receive television signals when it was just a set of rabbit ears.
AM Radio and Mobile Homes
Actually, a Rangemaster type transmitter mounted directly on your roof assuming it’s metal would not be a bad idea.
