No possible due to the frequency band of the radio. Governed by component values.

Hi,

I suspect that the extended transmit will really allow you TX on 2 Meter from 136-174 or thereabouts even with modifications.

At any rate, Air Bands are amplitude modulated, have you tried switching mode to "AM" when operating 116-136MHz??

Would you post back please on how the modification (extended transmit) was done; software programming of the EEPROM or jumpers (JP1001-1009).

Good luck and kind regards.

SOURCE: choosing the right frequencies for Uniden GMR1058-2CKB

Hello huko,

I see from your profile that you are in Bulgaria. Assuming that you are using the European PMR446 version of the Uniden radio in question, the channels / frequencies should be;

1 - 446.00625 MHz
2 - 446.01875 MHz
3 - 446.03125 MHz
4 - 446.04375 MHz
5 - 446.05625 MHz
6 - 446.06875 MHz
7 - 446.08125 MHz
8 - 446.09375 MHz
So, to operate on 446.09375 MHz you would chose channel 8.

If your radio has more then 8 channels, then you may have the U.S. version of the radio which operates on a different set of frequencies and does not have a channel that corresponds to 446.09375 MHz.

Best Regards,
Ken

if the band assigned to the radio doesn't cover the frequencies you want then it will not happen. you need to get the software and the right programming lead. make sure the mic socket is good and clean

How do you get the cobra walkie talkie to say the weather


Provided that your 2-way radio has the feature, there should be either a dedicated weather button or somewhere in the menus. Not sure what model you have. If it is a more advanced radio where you can set the frequency, the list of weather broadcast frequencies taken from NOAA are listed below. Two way radios are normally automatically programmed to one of these frequencies and usually require a push of a button.

Can the GRECOM PSR255. be used to scan for aircraft /airband frequencies


Your radio is not capable of recieving air band frequencies. It will only receive 4 bands consisting of: 26 - 54 MHz; 68 - 88 MHz; 137 - 174 MHz and 380 - 512 Mhz.

The VHF airband uses the frequencies between 108 (just above commercial FM radio) and 137 MHZ (just below 2 meter Ham radio). Amplitude Modulation ("AM") is the mode that transmissions are made. The lowest 10 MHz of the band, from 108-117.95 MHz, is split into 200 narrow-band channels of 50 kHz. These are reserved for navigational aids such as VOR beacons, and precision approach systems such as ILS localizers

Looking to find the frequenecies of the upper and lower channels



  • Hi I can help.
  • For the Grant 40 channel CB there are 40 frequencies I will list below.
  • When you refer to the upper and lower channels for this raidio you must mean USB (Upper Side Band) and LSB (lower side band).
  • This is called single side band modulation which is to say the the carrier is removed from the upper or lower sideband depending on which your pick and the signal goes farther on less power.
  • So the upper and lower side bands are the same frequency just upper side band or lower sideband.

In Thailand Cb radio users must use freq range 245.000 - 249.999 freqs. Do usa Cb's use this freq?


Thailand actually has three "CB" bands, the first is the same as the U.S. / CEPT (EU "European Community) band 26.965 - 27.405 MHz, the second is a 78MHz VHF mid CB band (I think its either 40 or 80 channels with FM mode) and then the 245.0000 - 245.9875 MHz VHF 80 channel band - apparently the law also stipulates that the 78MHz CBs must be yellow colored and the 245MHz CBs must be red colored.

But yeah, 245MHz Thailand VHF CBs are very illegal in the United States.
