Stretch-out the antenna first, then plug-in the Transmitter. For optimum signal strength, it's extremely important to stretch out the antenna first, and then plug-in the Transmitter.
And, when you do plug-in the Transmitter, plug the power supply the AC power pack into a wall outlet first, and then plug the other end into the Custom Power jack on the back of the Transmitter. After the Transmitter has calibrated, make sure to tell the client not to touch the antenna. Explain that if they do touch the antenna, it will knock the Transmitter out of calibration. Encourage your client to tune into the broadcast on a regular basis on their own car radio to check that the signal is calibrated and broadcasting clearly.
Show them how to unplug and re-plug the power cord at the back of the unit so they can re-power and re-calibrate the unit in case the antenna is touched, and the unit is knocked out of calibration. If you follow these simple steps, the signal should be crystal clear at almost any location. Low Power Radio Repository. Search this site. Building Bus'tr By Mike Sokol.

The Talking House Transmitter is a powerful tool when you use it to its fullest potential. This feature can save you the time and trouble of re-recording the part of the message which contains your free offers, and contact information.
The two-part message feature basically splits the 5-minute voice chip into two-parts. It allows you to record a part of your message once, and lock-it-in.
As we hope you are aware, the Talking House Transmitter allows you to broadcast your message in several ways: By recording a message in your own voice, using the hand-held microphone. By broadcasting directly from an external audio source, which allows you to utilize a longer pre-recorded message that exceeds the Message Chip storage time on your Transmitter. Lay out the antenna,.
Plug the power supply the AC power pack into a wall outlet. Then and only then plug the other end into the Custom Power Unit jack on the back of the transmitter. Find an open frequency. Talking House Transmitters have a patented tuning system designed to perfectly tune the output at every AM frequency.
However, to work best, the frequency you choose must be free and clear of any commercial or government radio broadcasts. Open and available AM frequencies vary by area. Therefore, it is up to you to find an open frequency. This is easy to do! There are very few commercial radio stations assigned to frequencies above AM.
Therefore, simply park your car in front of a listing. Tune your car radio to on the AM band, and go up one frequency at a time , , , etc. A frequency is open if all you hear is loud static-no voices or music. Two-Part Message System. Plus, this feature also. Although setting the frequency you are broadcasting on is easily accomplished using the up or down buttons on the front panel, the procedure to determine which frequency will work best for you, in your particular area, is more involved.
The reason for this is simple. We needed to choose some frequency, and since in many areas of the country works well, this is the one we chose. If it works well in your area, you may not have to go any further to find a suitable frequency to broadcast on. Antenna Tutorial. Maximizing Signal Distance and Reception Quality: What prevents you from receiving a good clear signal on your car radio is really dependent on what takes place between the transmitting antenna and the receiving antenna.
These parameters are: The selected frequency. This is why during your frequency testing stage you want to get the antenna wire outside a window, just until you confirm that you have good reception with the frequency that you are attempting to transmit on.
After you have found the frequency that works best in your particular area, one that gives you a good clear signal for the distance you need, you can then bring the Transmitter antenna inside the house to find a good location to transmit from.
Having the antenna wire up off of the floor and unobstructed will transmit a signal much farther than having the antenna lying at floor level. And again, in addition to making absolutely sure you execute a proper Outdoor Frequency Test, you want to remember these other guidelines for successfully setting up your Transmitter, as explained in your Talking House Operations manual: Your goal is to find at least 4 or 5 good frequencies that you will be able to use in your area.
By taking the time now to find more than one frequency, you won't be caught off guard when setting up at a specific location and your favorite frequency doesn't come in clear at that location. There are very few commercial radio stations assigned to frequencies between AM and AM. Therefore, this is the best place to start looking for the best frequencies. At night, many more distant stations can be picked up and can interfere with your signal. If you're planning to be heard at night, it is best to make sure that your chosen frequency is available both night and day.
Do not expect to get quite as good reception at night as you will during the day. The frequencies that are the most crystal clear on your car radio are the best to use. Due to their product name and everyone typing something different iam Radio, I A. Radio, i. The only review I found for their best model is here. I found a video featuring the audio of the new i. Radio compared to the talking house - but they use a old 4. Anyone care to comment about their experience with the i.
Radio model? Nearly all kit links and sources are non-existent today, and lots of dead links abound. Looking at the page for details , and what else is needed as not all parts are included in the kits, takes it out of my comfort zone and possibly price range even after saving. The other option is homebrew. As such many schematics I find are unbuildable as they usually do not list the transformer s voltage, old invalid part numbers only, or a generic part name at best.
I guess most assume if a person can build it they do not need a parts list - as lists are more rare than anything. I'm not sure why I found only one solid state build, but I'll happily build any if it meets my simple needs. If anyone has any options, experiences on the topics, or can point me to something that will fit my needs I am all ears.
At this point I'm tired of searching, I am not building a transmitter just for fun, and want something that will simply work. There has to be a solution that isn't just settling and without merit. I tired not to ramble, but it seems I wrote quite a post anyway. I made circuit boards for both.
Zero Hum. You should know this: It's hard to avoid the need to tinker with homebrew projects. RichPowers Participant. January 12, at am Radio Joe Participant. After doing that connect to the external antenna connector F59 center pin a short lead going into a loading coil For a fast loading coil, what works good is a ferrite loop stick antenna adjustable the kind found in crystal radio. Adjust the loop stick for maximum RF in the antenna wire. You can also experiment adding about uh or greater in series with the antenna wire antenna until you cancel out the capacitive reactance in the antenna wire to achieve maximum RF output I have also found that if the talking house transmitter will not calibrate and give an error, if you open the case, you will find a trimmer cap near the antenna, the standard antenna connection.
