Re: UV-5R Dual band mod to 220 MHz band


 

I've not had any splatter problems with the 3 I have.

Here's the instructions as promised:



How to program your Baofeng UV-5R to operate in the 1.25 Meter band (220 MHz).

?BEFORE you do this procedure, I ¡°HIGHLY¡± recommend that you download your current radio settings (database) to a folder that you can reload into your radio, just in case this doesn¡¯t work on your radio.

You must use CHIRP programming software to accomplish this modification as there is NO OEM programming software for this radio.

Connect up the radio via the programming cable.

Click on the ¡°RADIO¡± tab

Select ¡°Download from Radio¡±

Select the COM PORT

Select the ¡°Vendor: RADIODDITY¡±

Select the ¡°Model:??UV-5RX3¡±

Click ¡°OK¡±

This will download everything that¡¯s already programmed into the radio.? Once it¡¯s finished downloading, go ahead and make frequency modifications as desired.

Make sure to go to the Repeaterbook.com site and make a list of the 220 repeaters you want to use.? This may take some trial and error as not all the 220 MHz repeaters listed are actually on the air.? This band is sorely underused and this modification will, I hope, help to increase its usage.

Next step:

1) Click the ¡°SETTINGS¡± tab on the left side of the screen.

2) Click on the ¡°Other Settings¡± tab.?

3) Go to the line labeled: ¡°Upper VHF Limit (MHz).¡±? Change this line to read, ¡°250 MHz¡±.

Leave everything else as is.

Save the changes to the radio.? Give it a try!? I now have 3 handhelds that operate on the 2 meter, 220 MHz, and 440 MHz bands.

Let me know how you did!


Thanks!

Rod,
? ?Good info. Have you been able to test the signal to see if is OK with no splatter. I have five of these radios and would consider putting one on 220.?
