Based on the information you provided, it seems like the Kenwood TK-2000 radios you have may have been programmed with the wrong band split. The TK-2000 is available in both VHF and UHF frequency ranges, and it's possible that the radios you have are actually UHF models, despite being listed as VHF frequencies when you read the radios.
To check if your radios are UHF or VHF, look for a label on the back of the radio that specifies the frequency range. If it says UHF, then the radios can only accept frequencies in the 400-440 MHz range. If it says VHF, then the radios should be able to accept frequencies in the VHF frequency range.
If you've confirmed that the radios are indeed VHF models, then it's possible that the band split settings may need to be adjusted in the programming software to match the specific VHF frequencies you're trying to program. I recommend checking the manual for your programming software to ensure that you have selected the correct band split settings before programming the radios. If you're still having issues, it may be helpful to contact Kenwood customer support for further assistance.
This would depend on which area of radio you are asking about. In FRS/GMRS there is no "low frequency" though some manufacturers may use those phrases. FRS/GMRS radios are all in the UHF range, or ultra high frequency. In amateur radio we use UFH, VHF, and HF or high frequency. Though the FCC does not allow amateur use of the LF range, there are experimental stations that are allowed to operate ther. See http://www.arrl.org/lf-low-frequency for an explanation of this. For an understanding of the range of frequencies and what is UHF, VHF, HF, etc. see the chart at the lower part of the page at http://en.wikipedia.org/wiki/Radio_frequency
What you're looking for is called a "crossover". A crossover is an electronic filter for an audio or speaker circuit. In an audio circuit, a crossover is used to prevent or pass certain frequencies or a range of frequencies from passing through it. Since your sub will reproduce the bass or low frequencies, you don't want other speakers to reproduce them. A band pass filter on your door speakers will do this for you. A band pass filter passes only a range or "band" of frequencies and blocks those that are above and below the range or band of frequencies selected. Installing a band pass filter will prevent the very high & very low frequencies from getting to the door /dash speakers. Likewise, you should consider connecting a low pass filter to your subs, too. The low pass filters work a little differently from of the way band pass filters work - they only allow low frequencies to get to the sub - blocking all the other higher frequencies (your other speakers are better suited to reproduce those). Lastly, you would install a high pass filters on tweeters. Tweeters are designed to reproduce only the high frequencies - sending mid and low frequencies to them is wasting power and can cause damage to them.
You purchase the filters for specific crossover points (the block / unblocked point) as determined by the individual speakers. If a sub has a frequency response of 20Hz - 100Hz, a low pass filter of 100Hz would be ideal. Remaining filters would need to begin at 100Hz - assuming the mid-range speakers have a frequency response beginning at 100Hz. A band pass filter of 100Hz - 3KHz would fit the bill nicely if the mid-range speakers go up to 3Khz Match the high end of the band pass to the high end of the frequency response of the mid-range speakers. Next, a high pass filter at 3KHz would allow only the high frequencies to your tweeters. Basically, you want to have the entire audible range 20Hz - 20KHz covered by the speakers and have the crossover points that match the frequency response ranges of the speakers.
Hi
Motorola CP-200 have frequency range VHF: 136–162, 146–174MHz; UHF: 403–440, 438–470, 465–495MHz depending on the model Motorola AXU4100 have frequency range 435 - 480 Mhz The first model has a wider frequency range so it is best to include transmitter Motorola Axu4100 to transfer and try to receive signal to Motorola CP-200
The amps frequency setting is on LP (low pass) only playing bass so you have to put it on FR( Full Range) all frequency's and you'll get your sound back.
view sonic -E70fB monitor displaying H.V frequency out of range when ever i play a game on the monitor screen it is displaying h.v frequency out of range....how to solve this problem
