Disclamer: This blog will now be shared with friends only and GCC Engineering staff
and members only! Google has been leaking things out that should not be leaked out.
The station that was on AM 1620 kHz as an experiment using the same transmitter which did have problems with harmonics started to reside on 540 kHz the oldest frequency after Cybor 515 on 515 kHz. There is permission from the FCC that low power radio stations can run between 510 kHz to 1720 kHz and does not use an antenna no longer than 10 feet. Also the part 15 radio station cannot go more than 300 feet. The engineers such as me as an hobbyist does take range measurements and the signal did not go that far.
The Range Test : Its lucky that it just covers the entire apartment building and the outskirts
of the outside area to the small next door laundry room and apt. 102. So if you happen to be in the area. Give a listen with a amplified loop antenna or long wire antenna. You might not hear it that clear cause of other semi locals that are using the same frequency. Soon after I read more about low power AM transmission I will decide to use a wire antenna with the transmitter as long as it does not cause interference to the upper parts of the band. Since its a cheap build I don't think its appropiate to go over 300 feet cause of the harmonics on 1615 kHz. This is why its in limited and legal range within part 15 FCC regulations. The antenna that is being used right now is one of these antennas down here :
This transmitter was built using the 200 in One Electronic Lab Kit. You can get one of these from a flea market, ebay, electronics kit websites. I got this one for just a $1.00 at a Thrift Store. You can supply 6 AA batteries or a 1 9 volt battery. Follow the wiring diagram and have fun building it. More wiring instructions coming soon. Use the 2 terminals and add few more parts to the output transformer. I added a speaker crossover from a pioneer 40 watt speaker that crapped out and used 3 different resistors and a 1uF capacitor to the emitter of the transistor then used an external amplifier based on a LM-386 audio amp and piped the audio into the amplifier from the computer. More on this soon.
The station has been around since 1993 and has its old frequency 540 kHz. While WTRH-AM does not have a available transmitter for 1620 kHz WDAZ-AM is letting WTRH-AM use this transmitter under a schedule. So WDAZ-AM the 2nd oldest station that plays oldies of the 70's and 80's will share time with WTRH-AM on 540 kHz. The station can only go so far then you will need a loop antenna. Also to hear the station please visit the Mayfair Apartments area if you know anyone in that area in Virginia Beach. The station runs on a small 9 volt battery and uses a small antenna less than 10 feet. The station does not use any power amplifiers or huge antennas. This station is dedicated to the listeners in Mayfair Apartments and the visitors in the revolution.
All this station needs is just a 9 volt battery or 9 volt 20 mA solar panel to get on the air. This station is ment to be a survival "lost and stuck the island" low powered emergency transmission. It does not have any fancy compressors, power amplifiers, and huge antennas like other AM part 15 radio stations have. If this station was on an island with a 10 foot antenna it would cover the entire small island, but its not its in our community area. I will try to supply the schematic diagrams as soon as possible. The station is barely strong or not even loud. It goes far as a low powered 49 MHz walkie talkie.
Soon the station will be built on a PCB board when I get the parts I need to do it. Plus
I need to work on getting the sound quality better.
UPDATE - Summer 2009: The station will be transmitting from 1.5 volts to 6 volts which means that the station will be transmitting different programming using various power levels. WIth the security and unwanted listeners GCC engineering is working on various
experiments such as audio scrambling and nano transmitter jamming which means
use a jammer on the same frequency to block out the signal so it will not get out that much. Audio scrambling will be permitted when something bad is declared and we
do not any listeners except our fellow listeners, or when controversial programming
such as anti-nwo programming is on. But the best security that the station has is
nano transmission limiting.
UPDATE - Summer/Fall 2009 - GCC Radio Broadcasting has changed programming
schedules and stations. If you want to hear music like you did on 540 kHz you will
have to switch from AM to FM and tune to 88.3. WRSO-FM will be hosting the Music
war, infowar bumper music programming as of September 12, 2009. Which means the Alex Jones Show podcasts and other talk radio programming will be part of WTRH-AM AM 540 kHz. With AM 540 kHz you can hear the latest shows and information and when you need a break you can tune to 88.3 WRSO-FM for truth and music war programming.
UPDATE - Fall/Winter 2009 - GCC Radio is broadcasting a new radio station for the holidays while WRSO-FM, and WTRH-AM take a long break from broadcasting over the year. WBMQ-FM has now a new station more like a stunt broadcast which got released yesterday playing R&B, Hip Hop, Gospel, and Smooth Jazz holiday music since this kind of music is popular since we have alot of hip hop stations here in the 23462 area. GCC Radio is going to take over WTRH-AM for a limited time so we can work on a new programming schedule. WTRH-AM and WRSO-FM will do Christmas Music only on the weekends and alternate days on a limited schedule. and WBMQ-AM will be on air the other days. I just bought some contact cleaner to do the maintenence needed for the AM transmitter, I had to clean it and rewired the station and now it works good. WTRH-AM will return back on the air January 3rd, 2010. There will be new fresh music as well as the old favorites next year. So above all, the new R&B and Hip Hop Christmas music will share with WTRH-AM until regular broadcasting comes back on.
