[chirp_users] Baofeng UV-5R Frequency mod

Am I understanding that this can only apply in VFOs not the Working Bands?

    “One thing you can do is use CHIRP to set either 

    (or both or some combination) of the band limits

    to 100 MHz and 999 MHz.”

    Could you send me instructions on how to do this?  I could not find 

    anywhere in the chirp menu settings to allow me to modify the band 

    limits.  I have a 127.8 Frequency I would like to attempt to program 

    into my Baofeng UV-5R.  Any help would be appreciated.

    Thanks again, Tom

  Hi Tom,

  After you have downloaded from your UV-5R (or loaded a .img file that was created from your UV-5R) you should go to the Settings > Other Settings menu. Here is where you can set you VHF and UHF lower and lower limits. Here is how mine are set:

  VHF Lower Limit(MHz): 100

  VHF Upper Limit(MHz): 199

  UHF Lower Limit(MHz): 200

  UHF Upper Limit(MHz): 999

  Now when I am in either the [A] or [B] VFO set to VHF, I can key in frequencies form 100.0000 - 199.9975 MHz. When either VFO is set to UHF, I can key in 200.0000 - 999.9975 MHz. Obviously the frequencies that you can key in are dependent on the STEP setting for that display's VFO.

  The allowable range in CHIRP is from 1 to 1000, so there is nothing stopping you from setting either or both VHF and UHF VFOs to 1 - 1000.

  Also, if you want to scan between 800 and 850 MHz you would set either the VHF or UHF limits as shown below:

  VHF Lower Limit(MHz): 800

  VHF Upper Limit(MHz): 849

  Now with either the upper [A] or lower [B] VFO set to VHF, scanning the VFO with a STEP of 2.5 KHz will scan from 800.0000 to 849.9975 MHz.

  Any frequency that you can key in can be stored in a channel using menu 27 just like you would with any frequency with the factory specified limits.

  So here you go. Just don't expect any results much outside the factory specified limits.
