I'm looking at this for our chI need one for hearing impaired and another for translation. Are the transmitter frequencies changeable, or factory set?

They are factory set... But you can order from 6 different Freq Bands... K1, K2, K3, K5, K7, & K8

HI, If the audio you want to send to the two different receivers is the same, then you would use two of the same receiver with one transmitter. If you want different program to go to each receiver, then you would need two different complete systems. The transmitters and receivers are factory set to ONE frequency There are four different bands available for this 900 series. I hope this answers your question.

Not sure what your asking about the Mexican frequencies? But the unit transmits the frequencies required and has nothing to do with where you are, its line of sight transmission. But having said that it is possible that Mexico uses those frequencies for uses that would interfere with your unit or even render it unusable!! So I would try and find out if the frequencies are used by government or commercial entities before I would buy the unit. Hope this helps?

I am not sure of the frequency, but it works well with my stereo receiver and my computer headphone outlet. I am satisfied. For some reason, the transmitters has a short life (about 2 years). The speakers last a longer time.

It has been a few months since I messed with the one I bought, I do know that you have to have some steps in assigning it a frequency. If you have not tried it yet, I would manual set up the same frequency matching the transmitter to receiver. If you have them both on the same frequency already, I can't help you. Hope this helps

From my experience, tuning in shortwave mode is very very sensitive. A slight twitch and you're in/out of focus. I was only able to find a handful of stations. About 3 Spanish ones (either Spain or South America), 1 from Australia, and couple around US (mostly religious stations). I'm based in Colorado, US.

My understanding is that each has a unique frequency. However, to be certain, I would suggest calling Dogtra directly. They have excellent customer service! I lost our transmitter and they were so helpful in the purchase of a replacement.

I believe they all sound off with a verbal alert as to the unit that has detected a problem. I don,t think you can switch the frequency.

Typically the transmitters and receivers are on the same frequency. If you have dip switches on the receiver or transmitter, you might be able to change the frequency of one of the units.

Yes. After turning the transmitter back on, the output frequency will be whatever station you left it at

You have to find a vacant frequency on your FM radio with the unit off and adjust the frequency of your transmitter to that frequency with the transmitter on.

OK, so this is a really old post right now, but maybe someone is looking for the information.Any FM transmitter in LA is going to be so-so. There are simply so many FM stations in LA that it's hard to use a transmitter without interference. If you are driving in your car there will be several times where you will need to fidgit with the settings. It can get really annoying. So, will it work? Probably. Will it be stable or enjoyable? Probably not.

sorry I cannot help you. I gave it to my deaf boyfriend, and he never used it because its to complex technology for him..it appears the instructions are not as user friendly as they could be..perhaps call the manufacturer..good luck..

I don't know the answer to your question, but I purchased the transmitter & it works great! I have no complaints about it.

The frequency can be varied. I was able to adjust the frequency of the output low enough that I could hear it. I use the repeller at a higher frequency that I cannot hear. The highest frequency that one can hear decreases with age.

With the two I own, no. I suspected not, as there is no obvious way to adjust the send or receive frequencies. In most cases where multiple units are in use it would probably be necessary for each to act independently. Theoretically it could be possible to pair two or more sensors to a receiver during manufactured rather like multiple remote keys for a car, but I doubt if this would be done.

They are all on the same frequency. I originally purchased the "normal" size collars and found the didn't have enough punch. I have 1600 feet of wire on the same transmitter and it works well within range on all sizes of collar. FYI, The transmitter website lists applicable devices....

You need an attenuator to be in compliance with FCC part 15. The volume level on the front panel doesn't alter transmit power, just modulation level. The carrier is still at 100mw or 500mw (whether you modulate or not) and is what the FCC will triangulate on if there are complaints of interference from others. After you get your transmitter, tune through the FM band and notice any harmonics above and below the fundamental frequency you transmit on. Now go outside and see what the distance limits are (try it in your car). Be aware that vhf/uhf TV may also be affected (again, harmonics).
